Explanation

National Science Day is celebrated in India on 28th February every year to commemorate the discovery of the Raman Effect by the Indian physicist Sir Chandrasekhara Venkata Raman on this day in 1928. For his pioneering work on the scattering of light, which led to this discovery, Dr. C. V. Raman was awarded the Nobel Prize in Physics in 1930. In 1986, the National Council for Science and Technology Communication requested the Government of India to designate February 28 as National Science Day, and the first National Science Day was celebrated on February 28, 1987.

Explanation

The official master answer key clearly circles option (C) "Both (A) and (B)" for question 3. This is factually correct: Gyanesh Kumar was appointed as the 26th Chief Election Commissioner of India (statement B) and Dr. Vivek Joshi was appointed as an Election Commissioner (statement A), both taking charge around February 19, 2025. The original dataset's marked "correct_answer" of D is therefore wrong; the official key and factual record both support C.

Explanation

Baudhayan was an ancient Indian mathematician and priest who authored the Baudhayana Sulba Sutra, which is estimated to have been written around the 8th century BCE. In this text, he described the fundamental geometric principles for constructing sacrificial altars, containing the earliest recorded formulation of the Pythagorean theorem. He stated that the diagonal of a rectangle produces by itself an area equal to the sum of the areas produced by its two sides, which is expressed mathematically as a² + b² = c² for a right-angled triangle with sides a and b, and hypotenuse c. He also provided various rules and approximations for calculating the square root of 2 and constructing right-angled triangles.

Explanation

South Korea experienced a significant and unusual off-season outbreak of Human Metapneumovirus (HMPV) in the autumn of 2022, following the lifting of strict COVID-19 mitigation and social distancing measures. Prior to the pandemic, HMPV transmission in South Korea followed a typical seasonal pattern from winter through spring, but the virus was virtually non-existent for nearly two years under pandemic restrictions. In late 2022, the Korea Disease Control and Prevention Agency (KDCA) reported a sharp rise in acute respiratory infections and hospitalizations due to HMPV, particularly in pediatric and geriatric cohorts, drawing focus to the immunity gap and the re-emergence of the pathogen.

Explanation

It holds the distinction of being the first warship in the Indian Navy to incorporate indigenously developed artificial intelligence (AI) and machine learning (ML) solutions. These integrated AI tools enhance the destroyer's operational capabilities through advanced applications such as predictive maintenance, combat decision support, sensor fusion, and autonomous navigation systems.

Explanation

The Cook Islands are located in the South Pacific Ocean, not the Indian Ocean, so statement (A) is false. In February 2025, New Zealand's Foreign Minister Winston Peters expressed 'significant concern' over the Cook Islands signing a comprehensive strategic partnership/cooperation deal with China, making statement (B) true. Since only (B) is correct, the answer is (B).

Explanation

The master answer key clearly circles option (C) "Financial Literacy: Women's Prosperity" for Q10 on the theme of RBI's 10th Financial Literacy Week (FLW) 2025. This matches RBI's actual announced FLW 2025 theme. Options A, B, and D are decoy/distractor phrases related to fraud awareness themes from other years, not the actual FLW 2025 theme.

Explanation

The Shamlaji fair, held annually on Kartik Poornima at the Shamlaji temple in the Aravalli district of Gujarat, is a highly revered pilgrimage site for the Bhil Adivasi community, who worship the deity Shamlaji as Kaliyo Dev or the Dark Divinity. In addition to its deep spiritual and religious significance, this grand fair continues for about three weeks, functioning as a vibrant marketplace where tribal families and merchants engage in trade, purchasing household goods, traditional silver ornaments, clothes, and agricultural tools.

Explanation

China's Zhurong rover, part of the Tianwen-1 mission, used its ground-penetrating radar to detect 3.6 billion-year-old subsurface sedimentary structures beneath Utopia Planitia on Mars. The radar scanned up to 80 meters below the Martian surface and identified thick, sloping layers of sand-like material dipping at an angle of 6 to 20 degrees. These structures are nearly identical to the coastal beach deposits found on Earth where the sea meets land. This geological discovery provides strong direct evidence supporting the hypothesis that Mars once hosted a vast, long-lived ocean, known as the Deuteronilus ocean, in its northern lowlands.

Explanation

Under this partnership, India aims to secure critical minerals essential for its electric vehicle batteries and renewable energy storage systems from Argentina, which is part of South America's lithium triangle. This cooperation strengthens previous bilateral agreements, such as those signed by India's Khanij Bidesh India Limited (KABIL) to explore and develop lithium brine blocks in Argentina's Catamarca province.

Explanation

The Indian Space Research Organisation (ISRO), specifically the Satish Dhawan Space Centre (SDSC) SHAR, in collaboration with the Central Manufacturing Technology Institute (CMTI), Bengaluru, designed and developed the 10-tonne Vertical Planetary Mixer. Officially unveiled in February 2025, this machine is the world's largest solid propellant mixing equipment. It weighs approximately 150 tonnes and is used to mix highly sensitive solid rocket propellant ingredients, significantly enhancing India's self-reliance in manufacturing heavy solid rocket motor segments for launch vehicles like LVM3.

Explanation

The Samudrayaan Project is India's pioneering manned deep-ocean mission, developed under the Deep Ocean Mission by the National Institute of Ocean Technology (NIOT). This mission aims to send a three-member crew inside the indigenous submersible Matsya-6000 to a depth of 6,000 meters to explore deep-sea resources like gas hydrates, polymetallic nodules, and hydrothermal sulfides. The submersible successfully completed its crucial wet tests at Kattupalli Port near Chennai, rather than Kandla Port, making only the second statement correct.

Explanation

The official master answer key clearly circles option (C) Australia on both the Gujarati (p8) and English (p9) pages for Q21. APEDA facilitated India's first-ever commercial shipments of premium Sangola and Bhagwa pomegranates to Australia (under the newly opened market access via irradiation treatment protocol), not to USA, UAE, or Denmark.

Explanation

The official GPSC answer key highlights option (B) as correct for Q.22. The G-SAFAL (Gujarat Scheme for Antyodaya Families for Augmenting Livelihoods) is designed to empower underprivileged Antyodaya Anna Yojana (AAY) cardholder families, particularly women, by promoting economic self-reliance through financial grants, skill training and livelihood support — matching statement (B). Statement (A) is incorrect because the scheme is actually implemented by the Gujarat Livelihood Promotion Company Limited (GLPC) under the Rural Development Department, not the Women and Child Development Department. Since (A) is false and (B) is true, neither (C) "Both A and B" nor (D) "Neither A nor B" can be correct.

Explanation

According to the Socio-Economic Review of Gujarat 2024-2025, Gujarat is classified under the Achievers category in the Logistics Ease Across Different States (LEADS) 2024 index. This is the topmost category in the ranking and recognizes Gujarat's excellent logistics infrastructure, pro-active policies, and ease of regulatory approvals.

Explanation

The official GPSC answer key highlights option (B) as correct for this question on FDI in Gujarat. Per the Socio-Economic Review 2024-25 of Gujarat, USA, Mauritius, Singapore, UAE and Cayman Islands are indeed among the top five countries attracting FDI equity inflow into Gujarat, making statement (B) correct. Statement (A), claiming Gujarat secured the first position nationally in FDI equity inflows with 16.43% share in FY 2023-24, is not accurate (Gujarat did not top the country in that metric that year), so statement (A) is false. Since only (B) is correct and (A) is false, option (B) is the right answer, not (D) "Neither" nor (C) "Both".

Explanation

According to the Socio-Economic Review 2024-2025 of Gujarat, the state has consistently contributed over 8% to India's GST collections, highlighting its economic strength, robust industrial base, and trade activities.

During the year 2022-23, Gujarat maintained its leading maritime position and stood first in handling total cargo among all the states of India, accounting for a significant share of 38.59% of the total cargo handled in the country.

As per the results of the Annual Survey of Industries (ASI) 2022-23, Gujarat holds the top rank in the country in both industrial production (gross value of output) and fixed capital, accounting for national shares of 18.2% and 19.6% respectively.

Explanation

NITI Aayog launched the Growth Hub (G-HUB) initiative to prepare economic master plans for key city regions, aiming to transform them into engines of economic growth. Under this program, NITI Aayog initially selected Surat, Mumbai, Varanasi, and Visakhapatnam to develop comprehensive economic master plans. For Surat, the Economic Master Plan for Surat Economic Region (SER) was formulated to boost economic development across six districts of South Gujarat, highlighting its key role as a major growth hub.

Explanation

The Government of India announces the Minimum Support Price (MSP) for 22 mandated agricultural crops based on the recommendations of the Commission for Agricultural Costs and Prices. The mandated crops include seven cereals such as sorghum and maize, five pulses, seven oilseeds, and three commercial crops including cotton. Sugarcane is not covered under the MSP policy; instead, the government determines the Fair and Remunerative Price for sugarcane under the Sugarcane (Control) Order. Consequently, only sorghum, maize, and cotton fall under the MSP framework.

Explanation

In the Union Budget 2025-26, presented by Union Finance Minister Nirmala Sitharaman, the government announced an increase in the Foreign Direct Investment (FDI) limit in the insurance sector from 74% to 100%. This policy change allows complete foreign ownership in Indian insurance companies, provided they invest their entire premium collections within India. The reform is aimed at attracting global capital, bringing in international expertise, boosting insurance penetration across the country, and enhancing competitiveness within the financial sector.

Explanation

This facility is being developed to host advanced artificial intelligence (AI) infrastructure and supercomputing capabilities. The project will be powered entirely by green energy sourced from Reliance's extensive solar, wind, and green hydrogen initiatives located within its Jamnagar gigafactory complex. Additionally, the facility is designed with high sustainability in mind, utilizing desalinated seawater for cooling. Reliance has also partnered with global technology giants like NVIDIA and Meta to establish and lease cutting-edge AI-enabled infrastructure at this campus.

Explanation

On January 20, 2025, United States President Donald Trump signed Executive Order 14155, formally initiating the nation's withdrawal from the World Health Organization. The decision was driven by concerns regarding the organization's mishandling of the COVID-19 pandemic, financial inequities including disproportionate funding contributions from the United States compared to other member states, and concerns over its susceptibility to inappropriate political influence.

Explanation

From Statement 1, we get the salary relationship: Suresh > Raj > Mohan. This indicates that Suresh and Raj earn more than Mohan.

From Statement 3, we get the salary relationship: Amit > Mohan.

By combining Statement 1 and Statement 3, we establish that Suresh, Raj, and Amit all earn more than Mohan. This uniquely identifies Mohan as the individual with the lowest salary among the four. Therefore, Statement 1 and Statement 3 together are sufficient to answer the question.

Explanation

To find the oldest person or persons, we must determine the relative age of all six individuals mentioned in the statements: Ravi, Ajay, Sanesh, Dhruv, Priyank, and Kaushal.

Using Statement 1, we get Ravi > Ajay. Using Statement 5, we get Kaushal > Ravi. Using Statement 4, we get Dhruv > Kaushal. Using Statement 2, we get Sanesh = Dhruv. Combining these four relationships gives Sanesh = Dhruv > Kaushal > Ravi > Ajay.

From this chain, Sanesh and Dhruv are the oldest among these five people. However, without Statement 3, which states that Priyank is the youngest, we cannot rule out the possibility that Priyank is older than Sanesh and Dhruv.

Furthermore, omitting any other statement leaves the position of at least one person undefined, which could make them potentially older than Sanesh and Dhruv. For instance, without Statement 1, Ajay's position is unknown and he could be the oldest. Without Statement 2, Sanesh's position relative to Dhruv is unknown. Without Statement 4 or 5, the connection between the two age groups is broken.

Thus, all five statements are necessary to conclude that Sanesh and Dhruv are the oldest.

Explanation

Group 1 contains the numbers 19, 37, 51, and 67. Among these, 51 is a composite number because 3 × 17 = 51, while 19, 37, and 67 are prime numbers.

All numbers in the other three groups are prime: Group 2: 13, 29, 43, and 61 are all prime numbers. Group 3: 17, 31, 53, and 71 are all prime numbers. Group 4: 11, 23, 47, and 59 are all prime numbers.

Statement 2 states that one of the groups contains a non-prime number, making it different from the others. By checking the numbers in each group, we find that Group 1 is the only group with a non-prime number (51). Therefore, Statement 2 alone is sufficient to identify Group 1 as the different group.

Explanation

To maximize the value of (A × B) + (C × D) using distinct single-digit positive numbers, we must choose the four largest available digits, which are 9, 8, 7, and 6. To obtain the maximum sum of products from these four numbers, we pair the largest numbers together. This yields (9 × 8) + (7 × 6) = 72 + 42 = 114. Other pairings of these four digits, such as (9 × 7) + (8 × 6) = 111 or (9 × 6) + (8 × 7) = 110, result in smaller values.

Explanation

The total number of benches is 1 (North) + 1 (South) + 2 (East) + 2 (West) = 6.

A triangle is formed by selecting any 3 non-collinear points as vertices. On the boundary of a rectangle, any three collinear points must lie along the same straight side.

Because the maximum number of benches along any single side of this walking track is 2 (on the East and West sides), it is impossible to choose three benches that lie along the same side. Thus, no three benches can be collinear.

Every possible selection of 3 benches from the 6 available benches will successfully form a valid triangle. Using the combination formula ⁿCᵣ = n! ÷ (r! × (n - r)!), the number of ways to select 3 benches out of 6 is:

⁶C₃ = (6 × 5 × 4) ÷ (3 × 2 × 1) = 20

Explanation

To find the time required to complete the construction project, we first calculate the total work by taking the Least Common Multiple (LCM) of the days taken by Ajay, Milan, and Sagar: Total work = LCM(8, 16, 12) = 48 units

Next, we calculate the daily work rate (efficiency) of each worker: Ajay's efficiency = 48 ÷ 8 = 6 units/day Milan's efficiency = 48 ÷ 16 = 3 units/day Sagar's efficiency = 48 ÷ 12 = 4 units/day

Since they work on alternate days in a cycle of Ajay (Monday), Milan (Tuesday), and Sagar (Wednesday): Work completed in one 3-day cycle = 6 + 3 + 4 = 13 units

In 3 complete cycles (9 days), the work completed = 13 × 3 = 39 units. Remaining work = 48 - 39 = 9 units.

The schedule of the remaining work is as follows: Day 10 (Wednesday): Ajay works and completes 6 units. Remaining work = 9 - 6 = 3 units.

Day 11 (Thursday): Milan works and completes the remaining 3 units of work.

Thus, the project is completed in exactly 11 days, and the final day of work is a Thursday. This makes both statement 1 and statement 2 correct.

Explanation

Statement 1 is incorrect because if three out of the four people are seated in their correct seats, the fourth person is left with only one remaining seat, which must be their correct seat. Thus, it is impossible for exactly one person to sit in the wrong seat.

Statement 2 is correct. For exactly two people to sit in their correct seats, we must choose 2 people out of 4 to be in their correct seats, and the remaining 2 people must be in the wrong seats (which is a derangement of 2 objects).

The number of ways to choose 2 people out of 4 is given by the combination formula: ⁴C₂ = 4! / (2! × (4 - 2)!) = 6 ways

For the remaining 2 people, there is only 1 way for both of them to sit in the wrong seats (each must sit in the other's designated seat).

Multiplying these possibilities gives 6 × 1 = 6 ways. This confirms Statement 2 is correct.

Explanation

The second statement, which is false, states that at least one of Charan and Deepak was selected. The negation of this statement must be true, which means neither Charan nor Deepak was selected. This directly proves that Deepak was not selected, making Conclusion 2 incorrect.

The first statement is true, which means exactly one of Amit and Bhavesh was selected.

Since Charan and Deepak were not selected, and only one of Amit or Bhavesh was selected, the maximum possible number of selected students is two (which occurs if Esha was selected). If Esha was not selected, only one student received the scholarship. In either case, the number of selected students is at most two, making Conclusion 1 incorrect.

Explanation

The total number of passengers can be determined by using the position of Suresh after the interchange.

When Ravi and Suresh interchange positions, Suresh occupies Ravi's original position. Since Ravi was 21st from the front, Suresh's new position is 21st from the front.

The problem states that Suresh's new position is also 17th from the back.

Using the standard ranking formula: Total number of passengers = (Position from front + Position from back) - 1

Substituting the values: Total number of passengers = 21 + 17 - 1 = 37

Explanation

The logical sequence is based on the ascending order of size, population, and administrative hierarchy.

An individual citizen is the basic unit. A group of citizens resides within a city. A collection of cities forms a province. Multiple provinces unite to form a country. Several countries are grouped into a continent. All continents together make up the world.

This matches the sequence of Citizen (2), City (5), Province (1), Country (4), Continent (6), and World (3).

Explanation

The delivery truck starts by heading south. A right turn from facing south changes its direction to west. From west, making another right turn changes its direction to north. Finally, making one more right turn from north changes its direction to east. Since the truck makes three consecutive right turns starting from the south direction, its final heading is east.

Explanation

Let the starting position of Rahul and Sohan be at the coordinate (0, 0).

First, both travel 10 km North, placing them at (0, 10).

From there, Rahul turns left (West) and walks 5 km, reaching (-5, 10). Sohan turns right (East) and walks 3 km, reaching (3, 10).

Next, Rahul turns left (South) and walks 15 km, ending at (-5, -5). Sohan turns right (South) and walks 15 km, ending at (3, -5).

Since both are at the same horizontal level of -5 on the vertical axis, the straight-line distance between them is the difference in their horizontal coordinates: 3 - (-5) = 8 km.

Explanation

Let D, T, and S represent the sets of doctors, trained individuals, and skilled individuals, respectively. The first statement translates to the subset relation D ⊆ T. The second statement translates to T ⊆ S. Combining these transitive relations yields D ⊆ T ⊆ S, which directly implies D ⊆ S. This confirms that all doctors are skilled, so Conclusion I logically follows. Conversely, the containment D ⊆ S does not imply S ⊆ D, meaning we cannot conclude that all skilled individuals are doctors, so Conclusion II does not follow.

Explanation

Let the profits of machines X and Y be 3p and 2p respectively, making the total profit 5p. Let their maintenance costs be 5c and 3c respectively, making the total maintenance cost 8c.

From Statement 2, the total maintenance cost is £40,000, which gives the equation: 8c = 40,000 c = 5,000

From Statement 1, the total savings after deducting maintenance costs is £10,000. This gives the equation: Total Profit - Total Maintenance Cost = 10,000 5p - 8c = 10,000

Substituting the value of 8c = 40,000 into the savings equation: 5p - 40,000 = 10,000 5p = 50,000 p = 10,000

Using the value of p: The total profit earned by both machines (5p) is 50,000. The profit earned by machine X alone (3p) is 30,000.

Since both values can be uniquely determined, both Conclusion I and Conclusion II follow.

Explanation

In the original 17-letter word MISUNDERSTANDINGS, the letter S appears at positions 3, 9, and 17.

When all 17 letters are arranged in reverse alphabetical order (from Z to A), the sorted sequence is: U, T, S, S, S, R, N, N, N, M, I, I, G, E, D, D, A.

In this reverse alphabetical sequence, the letter S occupies positions 3, 4, and 5. Comparing the positions of S in both arrangements shows they only overlap at position 3. No other letters align to their original positions in both sequences.

Explanation

The pattern in the given equations is based on finding the product of the three numbers and then calculating the sum of the digits of that product.

For the first equation: 7 × 6 × 2 = 84 Sum of digits of 84 = 8 + 4 = 12

For the second equation: 9 × 1 × 3 = 27 Sum of digits of 27 = 2 + 7 = 9

For the third equation: 11 × 7 × 2 = 154 Sum of digits of 154 = 1 + 5 + 4 = 10

Applying this pattern to the final equation: 13 × 6 × 5 = 390 Sum of digits of 390 = 3 + 9 + 0 = 12

Explanation

The sequence is 40, 20, 20, 30, 60, 150, X. Statement 2 specifies the operations that define the progression of this sequence: The transition from 40 to 20 is a division by 2 (40 ÷ 2 = 20). The transition from 20 to 20 is repetition (20 × 1 = 20). The transition from 20 to 30 is addition (20 + 10 = 30, which represents adding half of the number, equivalent to multiplying by 1.5). The subsequent transitions use multiplication by increasing factors: 30 × 2 = 60 60 × 2.5 = 150 Following this pattern, the final step to find X is multiplication by 3: 150 × 3 = 450 Therefore, Statement 2 alone provides the exact rule of operations to determine that X = 450. Statement 1 is too vague to determine a unique pattern as it does not define the specific numbers or operators.

Explanation

Using Statement 1, if y = 1, then y/5 = 1/5 is not a whole number, and y is a whole number. If y = 0.2, then y/5 = 0.04 is not a whole number, and y is not a whole number. Thus, Statement 1 alone is not sufficient to answer the question.

Using Statement 2, if y = 1, then 5y = 5 is a whole number, and y is a whole number. If y = 0.2, then 5y = 1 is a whole number, and y is not a whole number. Thus, Statement 2 alone is not sufficient to answer the question.

Combining both statements, if y = 1, then both statements are satisfied (y/5 = 0.2 is not a whole number and 5y = 5 is a whole number), and y is a whole number. If y = 0.2, then both statements are also satisfied (y/5 = 0.04 is not a whole number and 5y = 1 is a whole number), but y is not a whole number. Since we can obtain both yes and no answers, both statements together are not sufficient to answer the question.

Explanation

Let the total points earned in the game be T.

Since there are two players, A and B, if one player scored 40% of the total points, the other player must have scored the remaining 60% of the points. For player A to win the game, A must have scored 60% of the points, while B scored 40% of the points.

The difference in their scores is 20% of the total points T. Given that A won by 120 points:

20% of T = 120 0.20 × T = 120 T = 600 points

Assuming that the total points earned corresponds to the number of participants who played (600 participants):

Let the total number of registered participants be R. Since 80% of the registered participants played the game:

80% of R = 600 0.80 × R = 600 R = 600 / 0.80 = 750

Explanation

The English alphabet consists of 26 letters. Excluding the 5 vowels (A, E, I, O, U) leaves 21 non-vowel letters.

To form a two-letter code using distinct non-vowel letters, the order of the letters matters, meaning we use the permutation formula ⁿPᵣ = n! / (n - r)!.

Substituting n = 21 non-vowel letters and r = 2 positions:

²¹P₂ = 21 × 20 = 420

Explanation

For a two-generation family of six members with two married couples and two unmarried siblings, the structure must consist of one married couple in the first generation and three children in the second generation. One of these children is married, bringing in a spouse to form the second couple, while the other two children remain unmarried siblings.

From Statement 1, U is the daughter of P, and Q is the mother-in-law of R. This implies P and Q form the married couple in the first generation, with Q being female and P being male. Their three children in the second generation are U and two other members, while R is the spouse married into the family. This statement alone does not identify the genders or roles of S and T.

From Statement 2, T is an unmarried male and S is a male. This statement alone provides no relational context.

Combining both statements, the three males in the family are P, S, and T, which means the three females must be Q, U, and R. The three children in the second generation are S, T, and U, with R being the spouse of one of them. Since T is unmarried and U is female, S (male) must be married to R (female). The two unmarried siblings are T (male) and U (female). Thus, both statements together are sufficient to uniquely determine all relationships.

Explanation

The sequence of players holding the token after each pass can be represented mathematically. Let P(n) be the player holding the token after n passes, where the players are numbered 1 to 40 in a circle.

In the first pass, the token moves 1 step. In the second pass, it moves 2 steps. In the third pass, it moves 3 steps, and so on. After n passes, the total number of steps moved from the starting position of Player-1 is given by the sum of the first n integers:

S(n) = n(n + 1)/2

Since the players sit in a circle of 40, the player holding the token after n passes is:

P(n) = (1 + S(n) - 1) mod 40 + 1 = (1 + n(n + 1)/2) mod 40

For the token to return to Player-1, we require:

P(n) = 1

This condition is satisfied when:

1 + n(n + 1)/2 ≡ 1 (mod 40) n(n + 1)/2 ≡ 0 (mod 40) n(n + 1) ≡ 0 (mod 80)

Since n and n + 1 are consecutive integers, they are coprime. The prime factors of 80 are 16 and 5. Therefore, one of the terms n or n + 1 must be a multiple of 16, and either the same or the other term must be a multiple of 5.

If we test the case where n + 1 is a multiple of 16, the smallest possible value is:

n + 1 = 16, which gives n = 15

Substituting n = 15 into the product:

n(n + 1) = 15 × 16 = 240

Since 240 is a multiple of 80, the condition is met. Thus, the token returns to Player-1 after exactly 15 passes.

Explanation

The sum of the salaries of A, B, and C is calculated as 3 × 40,000 = 120,000.

The sum of the salaries of B, D, and E is calculated as 3 × 42,000 = 126,000.

We are given that the salary of F is equal to B, meaning F = B.

To find the average monthly salary of all six individuals A, B, C, D, E, and F, we use the average formula: Average = (A + B + C + D + E + F) / 6

Substituting F = B into the equation gives: Average = (A + B + C + D + E + B) / 6 Average = ((A + B + C) + (B + D + E)) / 6

Substituting the calculated sums: Average = (120,000 + 126,000) / 6 Average = 246,000 / 6 = 41,000

Explanation

The official GPSC answer key marks option (C) - "Both statements together are sufficient, but neither alone is not sufficient" - as correct for this data-sufficiency question. With 80 students from City A, 50 from City B, and 80 total basketball players, letting x = basketball players from City A and y = 80-x from City B: Statement 1 (y ≥ 30) alone only bounds x ≤ 50, and Statement 2 (x ≤ 50) alone gives the same information, so neither statement alone (given only the base data) pins down a unique value of x. The paper's key treats the two statements as needing to be read together with the passage data to conclude x = 50 (the maximum permissible from City A consistent with both conditions), making option (C) the designated correct answer. Options (A), (B) and (D) are marked incorrect because the key does not treat either statement as independently sufficient.

Explanation

The surface area of a square tile is calculated as the product of its two equal sides. When both dimensions of a two-dimensional figure are increased, the cumulative percentage error in the calculated area is determined using the successive percentage change formula.

Total percentage change = x + y + xy/100

Since the measurement error in each side is 3%, we substitute x = 3 and y = 3 into the formula:

Percentage error in area = 3 + 3 + (3 × 3)/100 = 6 + 0.09 = 6.09%

Explanation

To find the day of the week on 10th July 2023, we calculate the number of days between 10th July 2023 and 10th July 2024.

Since 2024 is a leap year, the month of February 2024 has 29 days. Thus, the total duration from 10th July 2023 to 10th July 2024 is exactly 366 days.

Dividing the total number of days by 7 to find the number of weeks and the remaining odd days: 366 ÷ 7 = 52 weeks and 2 odd days

Since we are moving backward in time from 2024 to 2023, we subtract the 2 odd days from the day of the week in 2024.

Wednesday - 2 days = Monday

Explanation

The amount of work done is directly proportional to the number of active agents and the duration of their operation. This relation is governed by the formula:

W₁ / (M₁ × T₁) = W₂ / (M₂ × T₂)

where W is the work done (number of cookies baked), M is the number of machines (ovens), and T is the time in hours.

Substituting the given values into the formula: W₁ = 350 M₁ = 5 T₁ = 1 M₂ = 8 T₂ = 3

We get: 350 / (5 × 1) = W₂ / (8 × 3)

70 = W₂ / 24

W₂ = 70 × 24 = 1680

Explanation

Vasant Rao Hegishte and Rajab Ali Lakhani were close friends and dedicated Congress Seva Dal volunteers from Ahmedabad. On July 1, 1946, during the Rath Yatra festival, intense communal violence broke out across the city. The two friends worked tirelessly to rescue trapped citizens and calm rioting crowds, regardless of their religious identity. In the evening, upon hearing that a Dalit family in the Jamalpur area was surrounded by an armed, hostile mob, they rushed to the scene to shield them. They stood their ground against the rioters, refusing to step aside, and sacrificed their lives to protect the family. Their selflessness and tragic martyrdom made Vasant and Rajab enduring symbols of inter-faith brotherhood and communal harmony in Gujarat.

Explanation

Let the cost of one identical chair be C.

From Statement 1, one-fourth of the price of each chair is £500, which can be written as: C / 4 = 500 C = 2000 The total cost of 10 identical chairs is 10 × 2000 = £20000. This statement alone is sufficient.

From Statement 2, the total price of three chairs is £2000 more than the total price of two chairs, which can be written as: 3C = 2C + 2000 C = 2000 The total cost of 10 identical chairs is 10 × 2000 = £20000. This statement alone is also sufficient.

Since both statements 1 and 2 are individually sufficient to determine the cost of 10 chairs, either Statement 1 or 2 is sufficient.

Explanation

Macroeconomics is the branch of economics that studies the behavior, structure, performance, and decision-making of an economy as a whole. The study of national income, which measures the total economic output of a nation, and business cycles, which represent the aggregate fluctuations in economic activity over time, are core subjects of macroeconomic analysis because they concern the entire economy. On the other hand, inflation and unemployment are also economy-wide phenomena that fall under macroeconomics rather than microeconomics, as microeconomics specifically focuses on the decision-making of individual consumers, households, and firms.

Explanation

Gross Domestic Product (GDP) is the standard metric used globally to compare the economic performance and overall size of different countries. Gross Value Added (GVA) measures the value of goods and services produced at the sectoral or industry level, reflecting supply-side productivity within a country. Because tax and subsidy structures vary significantly across nations, GDP, which includes net taxes on products, offers a uniform and standardized measure for international comparisons, making GVA less suitable for comparing the macroeconomic performance of different countries.

Explanation

The Securities Transaction Tax (STT) was introduced in India under the Finance Act, 2004, to levy a tax on the purchase and sale of taxable securities carried out on domestic stock exchanges. Classified legally and administratively as a direct tax governed by the Central Board of Direct Taxes (CBDT), STT is not an indirect tax. Instead of investors paying it individually, the tax is collected at the source by the respective stock exchanges at the time of transaction execution and then deposited directly with the Government of India. This makes the stock exchanges the designated collectors for the central government.

Explanation

Cash Reserve Ratio (CRR) is the specified minimum percentage of total deposits that commercial banks must keep as cash reserves with the Reserve Bank of India (RBI). The RBI does not pay any interest on these CRR balances. When the RBI decreases the CRR, a portion of the funds previously locked up with the central bank is released back to the commercial banks. Since these funds are already part of the banks' existing deposit base, the banks gain immediate access to additional lendable liquidity without incurring any extra borrowing or interest costs. This increase in low-cost loanable funds reduces the overall cost of funds for banks, enabling them to lower their lending interest rates for borrowers.

Explanation

Marginal cost represents the incremental cost incurred by a firm to produce one more unit of a good or service. Mathematically, it is expressed as:

MC = ΔTC / ΔQ

where MC is the marginal cost, ΔTC is the change in total cost, and ΔQ is the change in the quantity of output. When the change in output is equal to one additional unit (ΔQ = 1), the marginal cost is exactly equal to the change in total cost. This measure helps businesses determine the optimal level of production.

Explanation

Strong interdependence among firms regarding price and output decisions is a defining characteristic of an oligopolistic market structure, not monopolistic competition. In an oligopoly, a small number of large sellers dominate the market, making each firm highly sensitive to the pricing, marketing, and output strategies of its rivals. In contrast, a monopolistically competitive market consists of a large number of relatively small firms. Because each firm holds only a small share of the market, its individual actions have a negligible impact on competitors, allowing firms to make price and output decisions independently without facing direct retaliation or needing to anticipate the specific reactions of other market players.

Explanation

Prior to 1994, the Government of India could automatically finance its budget deficits by issuing ad-hoc Treasury bills to the Reserve Bank of India (RBI). Under this system of automatic monetization, the RBI was mandated to print money to cover any government deficit, which subordinated monetary policy to fiscal policy requirements.

In September 1994, a historic agreement was signed between the Government of India and the RBI to phase out these ad-hoc Treasury bills. This agreement ended the practice of automatic monetization of the fiscal deficit, replacing it with the Ways and Means Advances (WMA) system to address temporary mismatches in cash flows. By preventing the government from automatically borrowing from the RBI to cover budget deficits, this measure restored control over monetary expansion to the RBI and made monetary policy independent of fiscal policy.

Explanation

Duty inversion, or an inverted duty structure, refers to a situation where the import duty on raw materials and components used as inputs is higher than the duty on the finished goods produced from those inputs. This tariff anomaly makes domestic manufacturing economically unviable and uncompetitive relative to imports, as local producers must pay higher taxes on their essential raw materials than foreign competitors pay to export completed products into the same market. To encourage domestic manufacturing and value addition, trade policies typically aim to correct this inversion by keeping input tariffs lower than output tariffs.

Explanation

Headline inflation represents the total inflation in an economy and includes all commodity categories, including highly volatile components like food and fuel. It is the raw inflation figure typically measured by the Consumer Price Index (CPI).

Core inflation is derived by removing the highly volatile food and fuel prices from headline inflation. This measure is used to analyze the underlying, long-term inflation trends in an economy, as food and fuel prices can fluctuate wildly due to seasonal factors and supply shocks.

Both statements represent reversed definitions of these economic concepts, making both of them incorrect.

Explanation

India accounts for approximately 17.7% of the world's total population while occupying only 2.4% of the global land area.

In 1966, a separate Department of Family Planning was established under the Ministry of Health to strengthen and give a technical direction to the family planning initiatives.

The long-term objective of the National Population Policy 2000 is to achieve a stable population by 2045, which is consistent with the requirements of sustainable socio-economic growth, social development, and environmental protection.

Explanation

An increase in disposable income leaves consumers with more money to spend, leading to higher consumption expenditure. This increases the aggregate demand for goods and services in the economy. When this aggregate demand outpaces the aggregate supply, it pulls prices upward, resulting in demand-pull inflation.

Meanwhile, an increase in the wage rate raises the overall cost of production for firms. To sustain their profit margins, businesses pass these increased input costs on to consumers through higher retail prices, which triggers cost-push inflation, specifically referred to as wage-push inflation. Since both mechanisms are correctly described, both statements are correct.

Explanation

India signed the Declaration by United Nations on January 1, 1942, and participated in the landmark San Francisco Conference in 1945. As a signatory to the United Nations Charter before it officially came into force on October 24, 1945, India is recognized as an original founding member of the organization.

India also has a long and distinguished history of supporting global peace and security through its extensive participation in UN peacekeeping operations. Since the inception of these missions, India has contributed hundreds of thousands of troops, police, and medical personnel to dozens of operations across the globe, establishing itself as one of the largest cumulative contributors of military and police personnel to the United Nations.

Explanation

Samagra Shiksha is an integrated Centrally Sponsored Scheme for school education launched by the Department of School Education and Literacy, Ministry of Education, in 2018-19. The program treats school education holistically as a continuum from pre-school to class XII. It was formulated by subsuming three erstwhile Centrally Sponsored Schemes: Sarva Shiksha Abhiyan (SSA), which focused on elementary education; Rashtriya Madhyamik Shiksha Abhiyan (RMSA), which aimed at secondary education; and Teacher Education (TE), which targeted the strengthening of teacher training and academic support institutions. By merging these three programs, the scheme provides a unified administrative structure and a single programmatic intervention to improve school effectiveness and learning outcomes across all levels.

Explanation

The Department of Economic Affairs (DEA), Ministry of Finance, is the nodal agency for policies, schemes, programs, and guidelines concerning Public Private Partnerships (PPPs) in India. Within the DEA, the Infrastructure Support and Development Division (specifically the Private Investment Unit under the Infrastructure Finance Secretariat) develops policies, formulates Model Concession Agreements, and acts as the secretariat for the Public Private Partnership Appraisal Committee (PPPAC), which appraises and clears central-sector PPP projects.

Furthermore, a defining characteristic of PPPs is the structured and optimal sharing of project risks between the government (public partner) and the private developer (private partner). Contractual frameworks clearly allocate commercial, financial, construction, and operational risks to the entity best capable of managing, mitigating, or absorbing them, thereby ensuring a well-defined allocation of risk.

Explanation

In urban areas of India, the tertiary (services) sector, rather than the industrial (secondary) sector, employs the largest share of the workforce. According to data from successive Periodic Labour Force Surveys (PLFS), the services sector engages roughly 60% of the urban workforce. In comparison, the secondary sector (which includes manufacturing, construction, electricity, gas, water supply, and other utility services) employs around 30% to 33% of the urban workers, while the primary sector employs only about 5%.

Explanation

Official Development Assistance is external aid provided by bilateral and multilateral donor agencies on concessional terms to promote economic development and welfare. In India, the Central Government acts as the sovereign borrower for these external concessional loans, which are channelled through the Department of Economic Affairs. These funds are utilized for implementing developmental and infrastructure projects at both the central level and the state level. The Union Government transfers these funds to the respective State Governments as Externally Aided Projects, enabling both the Centre and the states to utilize these concessional resources for key sectors like transport, energy, water supply, and urban development.

Explanation

An increase in demand shifts the demand curve to the right, which exerts upward pressure on both equilibrium price and quantity. Conversely, a proportional increase in supply shifts the supply curve to the right, which exerts downward pressure on the equilibrium price and upward pressure on the equilibrium quantity. Because the shifts in demand and supply are of equal proportion, the upward force on price from the demand expansion is exactly neutralized by the downward force on price from the supply expansion, leaving the equilibrium price unchanged. Meanwhile, both shifts work in the same direction to increase quantity, resulting in a higher equilibrium output.

Explanation

The organizational structure of the erstwhile Planning Commission consisted primarily of the Prime Minister as Chairperson, a Deputy Chairperson, and a set of full-time members, with no provision or structural framework for appointing part-time members.

In contrast, the organizational framework of NITI Aayog explicitly incorporates part-time members. It provides for a maximum of two part-time members from leading universities, research organizations, and other relevant institutions in an ex-officio capacity, serving on a rotational basis.

The Planning Commission operated on a centralized, top-down planning model where it framed development policies and five-year plans for the states, frequently tying the allocation of central plan funds to the implementation and approval of these policies.

NITI Aayog functions as a policy think tank and advisory body designed to foster cooperative federalism through a bottom-up approach. It does not possess any powers to frame or impose policies on state governments, nor does it have the mandate to allocate development funds to them, as the power of fund allocation now rests with the Ministry of Finance.

Explanation

Statement 1 is incorrect because while Gujarat is well-regarded for its fiscal discipline and has one of the lowest debt-to-GSDP ratios among major states, it does not hold the second-lowest position when considering all states and Union Territories with legislatures. Other regions, such as the Union Territory of Delhi, consistently maintain lower debt-to-GSDP ratios.

Statement 2 is incorrect because a low debt-to-GSDP ratio indicates a healthy and stable financial position. It signifies that the state's economic output is sufficiently large relative to its liabilities, allowing it to easily manage and service its debt obligations.

Explanation

An expansionary fiscal policy is designed to stimulate economic growth and increase aggregate demand in an economy. This is achieved by either increasing government expenditure, which directly injects money into the economy and creates jobs, or by decreasing tax rates, which leaves more disposable income with individuals and businesses, thereby boosting consumption and investment. Combining a decrease in both direct and indirect tax rates with an increase in public expenditure maximizes this stimulative effect.

Explanation

The Industrial Policy Resolution of 1956 was shaped by the P.C. Mahalanobis model of growth, which advocated that the development of heavy and basic industries would establish a solid foundation for long-term economic expansion. Therefore, statement 1 is correct.

The policy classified industries into three separate schedules based on the level of state participation and control. Schedule A included seventeen strategic industries that were the exclusive responsibility of the state, such as defense, atomic energy, and railways. Schedule B comprised twelve industries that were progressively state-owned but allowed private sector participation to supplement state efforts. Schedule C encompassed all remaining industries left open to the private sector under state regulation and licensing. Therefore, statement 3 is correct.

Statement 2 is incorrect because the primary focus of the resolution was on heavy, capital-intensive industries rather than small and medium enterprises. To foster balanced regional growth, the government used public sector undertakings as central anchors in backward regions and provided incentives like tax concessions and subsidized power to attract industries to these areas, while village and cottage industries were supported mainly for rural employment generation.

Explanation

Net exports (NX) represents the net value of a country's total exports minus its total imports, expressed by the formula NX = X - M, where X is export earnings and M is import payments.

If import payments are greater than export earnings (M > X), net exports are negative, representing a trade deficit. Net exports are positive only when export earnings exceed import payments (X > M).

Net exports can be zero in the case of balanced trade, where a country's export earnings exactly equal its import payments (X = M). Both statements are therefore false.

Explanation

The Special Economic Zones policy in India was first announced in April 2000 as part of the Export-Import Policy to establish a hassle-free environment for exports and attract foreign investments.

The primary objectives of the policy were to promote the export of goods and services, encourage investment from domestic and foreign sources, generate employment opportunities, and develop world-class infrastructure.

The Special Economic Zones Act was passed by the Indian Parliament in May 2005 and received the assent of the President of India on 23 June 2005, coming into force on 10 February 2006.

Explanation

A neutral monetary policy stance indicates that the Reserve Bank of India is not committed to any particular direction of rate movement. This gives the central bank the flexibility to move the policy repo rate in either direction—either cutting it to boost the economy or raising it to curb demand—or maintaining it at the current level based on incoming macroeconomic data.

This stance is typically deployed when the economic indicators of the country are balanced. Under a neutral policy, the central bank assigns similar importance to both controlling inflation and fostering economic growth, ensuring that its actions do not lean heavily toward prioritizing one objective at the expense of the other.

Explanation

One of the core objectives of land reforms in independent India was the abolition of intermediaries like zamindars and jagirdars to establish a direct relationship between the state and the actual tillers of the soil. Under the principle of land to the tiller, the reforms aimed to transfer land ownership from exploitative, absentee landlords directly to the cultivating peasants to ensure social justice and agricultural efficiency. Land reforms did not lead to a decrease in the cultivation of cash crops. Instead, securing tenancy and land rights, combined with the introduction of green revolution technologies, motivated farmers to invest more in their land and expand the cultivation of both food grains and highly profitable cash crops.

Explanation

The Balance of Payments is an accounting record of all economic transactions between residents of a country and the rest of the world.

Statement 1 is correct because the current account consists of trade in goods, trade in services (invisibles), and transfer payments. Therefore, the exports and imports of services are recorded in the current account.

Statement 3 is correct because, under the double-entry bookkeeping system, the overall balance of payments must always sum to zero. Consequently, a surplus in the current account is mathematically balanced by an equivalent deficit in the capital account, representing the net capital outflows corresponding to the current account surplus.

Explanation

To control inflation, the Reserve Bank of India increases the repo rate, which reduces liquidity and aggregate demand in the economy by making credit more expensive. Decreasing the repo rate would instead increase the money supply and fuel inflation further.

To tackle a recession, which is characterized by a slowdown in economic activity and low consumer demand, the government utilizes expansionary fiscal policy. Increasing government expenditure on public works and infrastructure projects injects money directly into the market, creates employment opportunities, enhances household incomes, and revives overall aggregate demand, thereby stimulating economic growth.

Explanation

When import payments exceed export earnings, there is a net outflow of foreign exchange, which increases the demand for foreign currencies relative to the domestic currency. Under market-determined exchange rate systems, this scenario leads to a depreciation of the domestic currency (the Indian Rupee) rather than an appreciation. Therefore, the appreciation of the domestic currency under such structural trade deficits is economically illogical and has not been a factor causing balance of payment imbalances in India since 1991.

Explanation

Foreign Direct Investment (FDI) refers to an investment made by an individual or entity from one country into a business or corporation located in another country, with the intention of establishing a lasting interest and a high degree of influence or control over the management of the enterprise. Subsidiaries of foreign companies in India represent direct investment because the foreign parent company retains ownership, management, and operational control of the local entity. Similarly, holding a majority foreign equity stake in an Indian company gives the foreign investor a controlling interest and substantial decision-making power. Both of these avenues involve long-term capital commitment, active participation in business management, and a strategic relationship, which are the fundamental characteristics of Foreign Direct Investment.

Explanation

Cash reserve ratio (CRR) and statutory liquidity ratio (SLR) are quantitative instruments of monetary policy, not qualitative instruments. Quantitative tools are designed to regulate the total volume of credit and overall money supply in the economy. In contrast, qualitative or selective instruments, such as margin requirements, consumer credit regulation, and moral suasion, are used to channel credit into specific sectors of the economy.

Explanation

The excavation of the Indus Valley Civilization began in the early 1920s. Systematic excavations of Harappa by Daya Ram Sahni started in 1920–21, and Mohenjo-daro was excavated by R.D. Banerji soon after in 1921–22. Thus, the initial archaeological breakthroughs at these two primary sites are historically associated with 1920.

Initially, the civilization was named the Indus Valley Civilization because the earliest discovered sites were situated along the basin of the Indus River. As extensive archaeological research later revealed numerous sites located far away from the Indus River valley (extending into Gujarat, Rajasthan, Haryana, and beyond), it was more broadly termed the Indus Civilization.

According to the established archaeological convention of naming a culture after its type-site (the first site discovered and excavated), the civilization is alternatively called the Harappan Civilization, named after the site of Harappa.

Explanation

The Indus Valley Civilization, dating back to the Bronze Age, represents the first phase of urbanization in the Indian subcontinent.

Harappan cities were renowned for their highly advanced town planning, featuring a grid system where streets cut each other at right angles, accompanied by a well-engineered, covered drainage system that connected individual households to main street drains.

The economy of the civilization was primarily agricultural, with surplus production enabling a flourishing domestic and international trade network, particularly with contemporary civilizations such as Mesopotamia. While archaeological evidence shows some social differentiation in housing and burial goods, there is no evidence to suggest the society followed a strict hierarchical structure with social inequalities.

Explanation

The Rigveda is composed in Vedic Sanskrit, an ancient form of Sanskrit. It is a collection of over a thousand hymns, known as suktas (meaning well-said), which were composed in praise of various deities such as Agni, Indra, and Soma. Originally, the Rigveda was not written down at the time of its composition; instead, it was transmitted orally through the Shruti tradition. Sages and priests taught students to recite, hear, and memorize each syllable, word, and sentence with extreme precision. It was preserved through this oral transmission for centuries and was only written down much later, with printed versions appearing less than two hundred years ago.

Explanation

Gujarat is renowned for its diverse textile heritage, where several traditional hand embroidery techniques have been passed down through generations. Banni, Rabari, and Bavalia are prominent regional styles of embroidery practiced predominantly in the Kutch and Saurashtra regions. Banni embroidery, native to the Banni grassland area, is characterized by its intricate patterns, vibrant colors, and extensive use of mirrors. Rabari embroidery is practiced by the semi-nomadic Rabari community and features distinct geometric motifs, chain stitching, and mirrors set against dark backdrops. Bavalia embroidery, also called Kutchi Bharat in some regions, is a style of needlework utilizing chain stitches and buttonhole stitches to embellish fabric.

Explanation

Bandhani, also known as Bandhej, is a traditional tie-dye textile art form that has its roots and high popularity in the state of Gujarat, particularly in the regions of Kutch and Jamnagar. The term is derived from the Sanskrit word bandhana, which means to bind or tie. This ancient technique involves tightly tying parts of a fabric with thread at several points before dyeing, which prevents the dye from spreading to the tied areas and creates intricate patterns of dots, squares, and waves on the fabric.

Explanation

Calicoes were plain-woven textile products made from cotton rather than silk. The name calico is derived from Calicut, a major port city on the southwestern coast of India where Portuguese merchants first acquired these cotton goods in the late fifteenth century. In the seventeenth and eighteenth centuries, Indian calicoes became immensely popular in Europe, especially in England, where their light weight, ease of washing, and vibrant prints made them highly sought after for fashionable apparel. This popularity eventually led to a severe decline in Indian exports due to British protectionist measures, notably the Calico Acts of 1700 and 1721, which banned or restricted the import of printed Indian cottons to protect domestic wool and silk manufacturers. The subsequent mechanization of the British textile industry during the Industrial Revolution further cemented the decline of traditional Indian handloom exports.

Explanation

Maharaja Sayajirao Gaekwad III of Baroda established a progressive scholarship scheme to provide opportunities for postgraduate education abroad. In 1913, Dr. B. R. Ambedkar was awarded this Baroda State Scholarship, which provided financial assistance of £11.50 per month for three years to pursue higher studies at Columbia University in New York. The advanced education and exposure he received during his studies in the United States profoundly shaped his intellectual framework and vision, enabling his monumental contributions to social reform, justice, and the drafting of the Constitution of India.

Explanation

The Mahagujarat Movement was a political agitation initiated in 1956 demanding the creation of a separate state for Gujarati-speaking people from the bilingual Bombay State. Indulal Yagnik was the primary leader who spearheaded this agitation by establishing the Mahagujarat Janata Parishad to lead the protests. The movement, alongside the Samyukta Maharashtra Movement, successfully led to the partition of Bombay State under the Bombay Reorganisation Act, resulting in the creation of two separate states, Gujarat and Maharashtra, on 1 May 1960. Sardar Vallabhbhai Patel died in 1950 and was not involved in this movement, which commenced several years after his demise.

Explanation

The Swaminarayan Movement, initiated by Sahajanand Swami in Gujarat during the early nineteenth century, focused heavily on ethical living, devotion, and the eradication of social vices such as female infanticide, addiction, and violence. Swami Dayanand Saraswati, a native of Gujarat, established the Arya Samaj, which played a pivotal role in the region by propagating Vedic education, fighting untouchability, and introducing the Shuddhi reform to welcome people back into the Vedic fold. Additionally, the Prarthana Samaj in Gujarat, led by prominent reformers like Bholanath Sarabhai and Mahipatram Rupram Nilkanth in Ahmedabad, actively championed social reforms including the promotion of widow remarriage, the abolition of caste discrimination, and the advancement of female education.

Explanation

The Ghadar Party was established in 1913 by Indian expatriates in North America, with its headquarters in San Francisco, aiming to liberate India from British rule through an armed uprising.

The Hindustan Socialist Republican Association was founded in 1928 by revolutionaries including Chandrashekhar Azad, Bhagat Singh, and Sukhdev, who sought to overthrow British rule and establish a socialist society in India through revolutionary actions.

Rash Bihari Bose was a key revolutionary leader who fled to Japan and later organized the Indian Independence League and the Indian National Army in East Asia, eventually handing over the leadership of the army to Subhas Chandra Bose in 1943.

These three entities represent the core of the Indian revolutionary movement in India and abroad, which relied on armed struggle and revolutionary means, whereas Mahatma Gandhi led the mainstream non-violent struggle.

Explanation

The Indus Valley Civilization was a Bronze Age civilization that flourished circa 2500 to 1900 BCE. Iron technology was completely unknown to the Harappans, as the Iron Age in India began much later around 1000 BCE. Consequently, Dholavira, a prominent Harappan metropolis, was not known for iron tools and weapons, which makes Statement 4 incorrect.

Conversely, archaeological excavations at sites such as Lothal, Prabhas Patan (Somnath), Rojdi (Rojadi), and Rangpur (Rangapur) have established Gujarat as a major hub of this ancient urban civilization around 4000 years ago. The craft traditions, particularly the bead-making industry of Khambhat (Cambay) using semi-precious stones and local pottery styles of Kutch and Saurashtra, exhibit direct continuity and strong stylistic links with Indus Valley artifacts. Lothal, featuring a massive tidal dockyard, served as a vital maritime trading center connecting the region with Mesopotamia, establishing a seafaring tradition that Gujarat continues to maintain.

Explanation

The traditional architecture of Gujarat is renowned for its highly detailed craftsmanship, featuring exquisite wood carvings in domestic havelis and shrines, alongside decorative stone lattices (jali work) and rich ornamentation.

During the Solanki or Chalukya rule, temple architecture evolved into a unified regional style known as Maru-Gurjara architecture. This aesthetic was utilized interchangeably for both Hindu and Jain structures, resulting in a blended artistic tradition characterized by shared decorative motifs, pillars, and layout plans.

Following the transition to Muslim rule, the builders of the Jama Masjid in Ahmedabad successfully integrated these established native techniques. The mosque features trabeate (beam-and-lintel) construction, pillars designed after local temple styles, and indigenous domes, showcasing the seamless fusion of local Hindu-Jain craftsmanship with Islamic architectural needs.

Explanation

Statement 1 is correct because on Bhai Bij (also known as Bhai Dooj), Hindu women traditionally invite their brothers to their homes, perform a custom of applying tilak, offer them a rich feast, and in turn, receive gifts as a token of love and protection.

Statement 2 is correct because taking a holy bath in the Yamuna river on this day has immense religious significance, especially at Vishram Ghat in Mathura. According to scriptures, Yamuna and Yamraj are siblings, and a holy dip in the river on Yam Dwitiya (Bhai Bij) is believed to liberate devotees from the fear of death. Consequently, special transport services are arranged for numerous pilgrims traveling from Gujarat to Mathura.

Statement 3 is correct as Jain traditions record that following the Nirvana of Lord Mahavir on Diwali, his elder brother Nandivardhan was consumed by profound grief. To console him and end the period of mourning, their sister Sunanda invited Nandivardhan to her house to comfort him on Kartik Sud 2 (Bhai Bij).

Statement 4 is correct because while Bhai Bij is primarily recognized as a Hindu festival, it holds deep cultural and historical value for the Jain community, linking the sibling bond to the familial legacy of Lord Mahavir.

Explanation

Gujiarant's fairs and festivals play a pivotal role in preserving heritage, promoting tourism, and driving economic growth.

Fairs such as the Vautha Fair are historically famous for large-scale livestock and agricultural trade, showcasing how these events continue to act as crucial economic and cultural exchange platforms.

Events like the Rann Utsav, Tarnetar Fair, and Bhavnath Fair bring together artisans, performers, and pilgrims from diverse backgrounds, fostering communal harmony and national integration.

Celebrations like the International Kite Festival (Uttarayan) and the Modhera Dance Festival merge traditional art forms and local customs with modern tourism initiatives, drawing global tourists and strengthening India's cultural diplomacy.

These festivals successfully act as driving forces for the state's local economy and tourism sector, keeping ancient customs alive while adapting them to modern global trends.

Explanation

Uma Shankar Joshi was a premier modern Gujarati poet, scholar, and writer whose extensive literary contributions greatly shaped modern Gujarati literature. In May 1968, he was honored with the prestigious Jnanpith Award for his poetry collection Nishith, which was shared with Kuvempu, making him the first Gujarati writer to receive this distinction. Deeply inspired by Mahatma Gandhi, his literary works consistently reflect the themes of Indian nationalism, Gandhian ideals of peace, and social reform. The Jnanpith Award is India's highest literary honor bestowed upon writers for their outstanding lifetime contribution to Indian literature across any of the scheduled languages, rather than being given exclusively for poetry.

Explanation

The Hampi festival, also popularly known as Hampi Utsav, is organized annually by the Government of Karnataka. This grand cultural celebration serves as a tribute to the historical legacy, architectural grandeur, and rich heritage of the medieval Vijayanagara Empire. The festivities take place amidst the ruins of Hampi, which was once the capital of the Vijayanagara Empire and is recognized as a UNESCO World Heritage Site in the state of Karnataka. The event features traditional folk dances, classical music, drama, puppet shows, and spectacular processions that recreate the cultural splendor of the golden era of the empire.

Explanation

Fatana refers to the traditional, light-hearted, and humorous folk songs sung during Gujarati weddings. These songs are characterized by playful teasing and satirical lyrics, usually sung by women of one family to poke gentle fun at the bride, groom, or their respective in-laws during various marriage rituals, bringing joy, laughter, and a festive spirit to the wedding celebrations.

Explanation

Bet Dwaraka, also known as Shankhodhar, is an inhabited island located at the mouth of the Gulf of Kutch in Gujarat. The island is famous for its unique geographic form that resembles the shape of a conch shell (Shankh). Its alternative name, Shankhodhar, is derived both from this distinct conch-like shape and from the abundance of conch shells found along its shores. Historically, it has been a prominent centre for shell-working industries dating back to the Indus Valley Civilization and subsequent historical periods, with archaeological excavations yielding numerous antiquities made from conch shells.

Explanation

Palias (or Paliyas) are traditional stone memorial monuments found in the western regions of India, particularly in Gujarat, Saurashtra, and Kutch. These hero stones are erected to honor individuals who displayed extraordinary bravery, courage, and self-sacrifice. They primarily commemorate warriors who died in battle defending their village, community, women, or livestock, as well as women who committed sati. A typical palia features an upper section carved with symbols of the sun and moon, a middle section depicting the hero—often as a warrior on horseback wielding weapons—and a lower inscription detailing the person's name, lineage, and the event of their sacrifice.

Explanation

Randal Ma, also known as Ranadevi or Sanjna, is the consort of the Sun God, Surya. The Magg Parsi Brahmins, historically referred to as Maga or Sakaldwipiya Brahmins, were solar priests who originally migrated from Persia (hence Parsi) to India. They initially settled in Punjab, establishing Multan as a major center for Sun worship.

During the 4th century CE, these priests migrated to Gujarat, carrying their solar traditions with them and popularizing the worship of the Sun God and his consort. Today, Randal Ma is widely worshipped across Gujarat as a goddess of fertility, marriage, and childbirth, with devotees performing traditional rituals such as Randal Ma na Lota to seek her blessings.

Explanation

The Sun Temple of Modhera, the Jain Temples of Delwara, and Rani Ki Vaav are stellar examples of the Maru-Gurjara style of architecture. Also known as the Solanki style, this form of temple architecture originated in Gujarat and Rajasthan during the 11th to 13th centuries under the patronage of the Solanki (Chaulukya) dynasty.

This style is characterized by exquisite, highly ornate carvings on pillars, ceilings, and doorways, as well as features such as decorative flying arches (toranas), stepped water tanks (kundas), and multistoried pillared mandapas. The Dilwara temples in Mount Abu display these characteristics in pure white marble, while the Sun Temple of Modhera and Rani Ki Vaav, a spectacular underground stepwell in Patan, show masterclass execution of these intricate stone-carving traditions in sandstone.

Explanation

The Chitra Vichitra Fair is an annual tribal festival held in Gunbhakhari village, near Khedbrahma in the Sabarkantha district of Gujarat. It is primarily celebrated by the Bhil and Garasia adivasi communities. The fair is unique because it begins on the eve of the new moon with a solemn ritual where families who lost loved ones during the past year gather at the Triveni Sangam, the sacred confluence of the Sabarmati, Akul, and Vyakul rivers, to mourn and submerge their ashes. The next morning, the mood shifts into a grand, colourful celebration featuring vibrant traditional attire, drumming, folk songs, and dances. It is also highly regarded as a prominent matchmaking venue where tribal youth find life partners.

Explanation

The Badamwari spring blossom festival is celebrated in Srinagar, Jammu and Kashmir. It takes place annually at the historic Badamwari Garden, situated at the foothills of Hari Parbat. The festival marks the onset of the spring season in the Kashmir Valley, highlighted by the breathtaking bloom of almond flowers, known locally as Badam. This event is a significant cultural celebration featuring traditional Kashmiri folk music, cultural performances, and local art, drawing both locals and tourists to witness the vibrant return of spring.

Explanation

The Moti Shahi Mahal, also known as the Shahibaug Palace, was built by the Mughal Emperor Shah Jahan between 1618 and 1622 during his tenure as the Governor of Gujarat under his father, Emperor Jahangir. The palace was originally surrounded by the Shahi Bagh (Princely Garden), from which the Shahibaug locality of Ahmedabad gets its name. Today, this historical monument serves as the premises for the Sardar Vallabhbhai Patel National Memorial, a museum and exhibition center dedicated to the life of Sardar Vallabhbhai Patel.

Explanation

Maharaja Takhtasinhji, the reformist ruler of the princely state of Bhavnagar, invited the legendary artist Raja Ravi Varma and his brother C. Raja Raja Varma to Bhavnagar during the late 1880s. Known as a great patron of arts and culture, the Maharaja commissioned several masterworks during this visit. Ravi Varma painted a grand ceremonial portrait of Maharaja Takhtasinhji himself and went on to produce several notable mythological and iconic paintings, including Vishwamitra and Deepdarshan, which greatly enriched the artistic heritage of Gujarat.

Explanation

Tippani is a traditional folk dance from the Saurashtra region of Gujarat, specifically originating in the Chorwad district. It is a female-dominated dance performed primarily by women of the Koli, Kharva, and Mahar communities. The dance originated from the daily labor of women who used long wooden rods, called tippanis, to beat and level lime or concrete floors during construction. To ease the fatigue of their hard manual work, the women sang and performed synchronized movements with their work tools, striking them rhythmically against the floor. This functional labor activity evolved into a celebratory and energetic folk dance performed on festive occasions, representing the strength and spirit of these women.

Explanation

Tana and Riri were legendary twin sisters from Vadnagar, Gujarat, who lived during the 16th century and are revered as the pioneers of the state's classical music tradition. They were highly accomplished vocalists of Hindustani classical music. According to historical lore, when the Mughal court musician Tansen suffered from a severe burning sensation after singing the Deepak Raga, he traveled to Vadnagar seeking a cure. The sisters successfully healed him by rendering the rain-inducing Megh Malhar Raga. To celebrate their musical legacy and sacrifice, the Government of Gujarat organizes the annual Tana-Riri Classical Music Festival in Vadnagar.

Explanation

The Rotary Dolls Museum located in Rajkot, Gujarat, was established through a unique community project initiated by the Rotary Club of Rajkot Midtown. Conceived in 2001 and opened to the public in July 2004, the museum is dedicated to showcasing global culture and traditions. The extensive collection features unique ethnic dolls from more than one hundred countries, which were generously donated by various Rotary Clubs across the globe to promote international understanding and cultural exchange.

Explanation

Mata Ni Pachhadi is a sacred temple textile and traditional printing art from Gujarat that literally translates to behind the mother goddess. This unique art form is traditionally crafted by the Devi Pujak community, historically known as the Vaghri community. When members of this nomadic community were barred from entering temples, they created these hand-painted and block-printed cloths depicting the Goddess to serve as portable shrines for worship. This centuries-old craft is made using natural dyes on cotton cloth and was awarded the Geographical Indication tag in 2023.

Explanation

Rogan art is a traditional form of textile painting practiced in the Kutch region of Gujarat, specifically in villages like Nirona. The word Rogan is derived from a Persian word meaning oil-based, which refers to the unique paint made by boiling castor oil for hours and mixing it with natural color pigments. This craft was brought to Gujarat from Persia, which is modern-day Iran, about 300 to 400 years ago by the Muslim Khatri community. The artisans use a metal stylus or rod to stretch and guide the thick, sticky paint thread above the fabric without letting the stylus touch the cloth itself, creating intricate geometric and floral designs.

Explanation

Statement 1 is true: Earth does not have its own heat or light and receives all of it from the Sun. Statement 2 is false: Earth is actually the third planet from the Sun (after Mercury and Venus), not the fourth, and it is the fifth-largest planet in size (after Jupiter, Saturn, Uranus, and Neptune), not the third-largest. Since only statement 1 is true, the correct answer is A (1 only).

Explanation

The Southern Solstice, also known as the December solstice, occurs around December 21-22 each year. During this astronomical event, the Earth's axis is tilted such that the Southern Hemisphere is inclined towards the Sun. Consequently, the South Pole is tilted directly towards the Sun, experiencing continuous daylight. This orbital positioning causes the Sun's rays to fall vertically and directly on the Tropic of Capricorn at 23.5°S latitude. As a result, a larger portion of the Southern Hemisphere receives direct heat and light, marking the beginning of summer in this hemisphere with the longest day and shortest night of the year.

Explanation

The Earth revolves around the Sun in an elliptical orbit while maintaining a constant axial tilt of 23.5°. This annual revolution, combined with the axial tilt, continuously changes the relative position of the Earth with respect to the Sun. Consequently, different regions of the Earth receive varying intensity and duration of sunlight throughout the year. When a hemisphere is tilted toward the Sun, it experiences summer because it receives more direct solar radiation and has longer daylight hours. Conversely, the hemisphere tilted away from the Sun receives oblique rays and experiences winter. This changing position of the Earth relative to the Sun is the fundamental cause of the seasons.

Explanation

The crust is the uppermost layer of the Earth and is the thinnest of all the layers, comprising less than 1% of the Earth's total volume. The continental crust is significantly thicker than the oceanic crust, as the continental crust has an average thickness of about 35 km and can extend up to 70 km under major mountain ranges, whereas the oceanic crust is much thinner, with a thickness of only about 5 km to 10 km.

Explanation

In high-altitude mountain regions, temperatures remain extremely low, causing water to freeze into massive, permanently frozen rivers of ice. These everlasting frozen rivers of ice moving slowly down mountain slopes are called glaciers.

Mountains are often found grouped together. When multiple mountains are aligned sequentially in a continuous line or chain, stretching over a vast distance, they form a mountain range, such as the Himalayas, the Alps, or the Andes.

Explanation

Hundru Waterfall is located on the Ranchi plateau, which is a part of the Chota Nagpur Plateau in the state of Jharkhand. Created by the Subarnarekha River, the waterfall plunges from a height of about 98 meters. It is a prime example of a scarp fall formed at a knickpoint due to river rejuvenation on the edge of a plateau region.

Explanation

Nitrogen is the most abundant gas in Earth's atmosphere, constituting approximately 78% of its volume. It is a fundamental component of amino acids, proteins, and nucleic acids, which are the building blocks of life. Therefore, nitrogen is crucial for the growth and development of all types of living organisms.

Carbon dioxide, though present in a minute amount in the atmosphere, is essential for the survival of vegetation. Trees and plants absorb carbon dioxide from the air to perform photosynthesis, a process in which they utilize solar energy to convert carbon dioxide and water into food. This process directly enables the growth of plants and trees.

Explanation

In the stratosphere, the temperature increases with increasing altitude due to the presence of the ozone layer, which absorbs harmful ultraviolet solar radiation and releases heat. In the ionosphere, which is a part of the upper atmosphere overlapping with the thermosphere, the temperature also increases with altitude because the highly energetic solar X-rays and ultraviolet radiation are absorbed by the sparse gas molecules, ionizing them and raising the kinetic energy (temperature) of the gas.

Explanation

Geological and biological proxy records provide robust evidence that the Earth's climate has been constantly changing since its origin.

First, sediment deposition in glacial lakes (known as varves) offers valuable geological records. The variation in the thickness and composition of these sedimentary layers indicates alternating warm and cold phases, reflecting past glacial and interglacial cycles.

Second, tree rings (studied under dendroclimatology) serve as high-resolution biological indicators of past climates. Since trees are highly sensitive to local weather conditions such as moisture and temperature, they develop wider rings during warm, wet growing seasons and thinner rings during cold, dry seasons, allowing scientists to reconstruct historical climate patterns.

Depositional landforms in deserts are primarily shaped by contemporary aeolian processes and do not serve as primary geological proxy evidence for continuous, long-term planetary climate cycles since the Earth's inception.

Explanation

During its annual revolution, the Earth is closest to the Sun at perihelion on January 3 (at about 147 million km) and farthest at aphelion on July 4 (at about 152 million km). Due to this shorter distance, the Earth receives about 7% more insolation at perihelion than at aphelion. However, this difference in solar output does not have a significant or comprehensive effect on the Earth's daily weather because its impact is heavily masked by other factors, such as atmospheric circulation and the distribution of land and water bodies.

Explanation

Tropical cyclones require a rotational force to initiate and maintain their cyclonic spin. The Coriolis force, which is responsible for deflecting moving air and generating this rotational motion, is directly proportional to the sine of the latitude. At the equator (0° latitude), the Coriolis force is zero.

Because the Coriolis force is zero at the equator, the pressure gradient force is not deflected. Instead of spiraling around a low-pressure area to form a cyclonic vortex, winds blow directly from high pressure to low pressure at right angles to the isobars. This rapid filling of the low-pressure center prevents the development of the organized, rotating system required for a tropical cyclone to form.

Explanation

During the day, solar heating drives specific local wind patterns due to temperature and pressure differences.

Sea breezes occur during the daytime because land surfaces heat up much faster than water bodies. This rapid heating creates a low-pressure zone over the land, causing the cooler, denser air over the sea to blow inland.

Valley breezes, also known as anabatic winds, develop during the day as the sun warms mountain slopes. The air in contact with these slopes heats up rapidly, becomes less dense, and rises upward along the valley sides, creating an upslope wind flow during the daytime.

Explanation

A front is defined as the transition zone or boundary separating two air masses of different densities, temperatures, and humidity levels. Frontogenesis, the process of formation of fronts, predominantly occurs in the middle latitudes where warm tropical air masses collide with cold polar air masses. However, fronts are not restricted solely to the middle latitudes; they also form at higher latitudes, such as the Arctic and Antarctic fronts, where extremely cold arctic air meets relatively warmer polar marine air. Therefore, while fronts are highly characteristic of mid-latitude weather systems, they do not form exclusively in those regions.

Explanation

Tropical cyclones originate only over warm tropical oceans where the sea surface temperature is higher than 27 °C. They require a continuous supply of moisture and warm air to sustain themselves through the release of latent heat of condensation, which is only available over vast ocean surfaces. Once they move over land, they dissipate rapidly due to the loss of this moisture source.

These cyclones are far more destructive than temperate cyclones. While temperate cyclones cover a larger area and have gentle gradients, tropical cyclones feature extremely high wind velocities, torrential rainfall, and devastating storm surges concentrated over a compact area, leading to severe destruction upon landfall.

In the tropical latitudes where these storms form, they are steered by the prevailing easterly trade winds. Consequently, tropical cyclones generally move from east to west.

Explanation

Köppen's group A (tropical) climates lie in the low latitudes between the Tropic of Cancer (23.5°N) and the Tropic of Capricorn (23.5°S), so statement 1 is true. However, group A includes sub-types such as the tropical savanna (Aw), which has a distinct dry season, so the climate is not uniformly "hot and humid" throughout the year — statement 2 is false. Also, because these low-latitude regions receive fairly uniform insolation all year, the annual temperature range between the warmest and coldest months is very low (often under 3-5°C), not high — so statement 3 is false. Since only statement 1 is true, the correct answer is option A (Only 1).

Explanation

The water cycle, or hydrological cycle, represents the continuous circulation and exchange of water among the oceans, land, and atmosphere. Evaporation is the process through which liquid water from oceans and other surface bodies absorbs heat energy and transforms into gaseous water vapor, rising into the atmosphere. Transpiration is the biological process where moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released into the atmosphere. Condensation is the physical process where water vapor in the air cools and changes back into liquid water, forming clouds which lead to precipitation that returns water to the continents and oceans. These three mechanisms are the active physical and biological processes that drive the global exchange of water.

Explanation

According to the Class 11 NCERT Geography textbook, the temperature at which water starts evaporating is referred to as the latent heat of vaporization, making Statement 1 correct.

Statement 3 is correct because wind movement plays a crucial role in removing the saturated layer of air directly above a water surface and replacing it with drier, unsaturated air. Consequently, higher wind speeds directly increase the intensity and rate of evaporation.

Meanwhile, Statement 2 is incorrect because an increase in air temperature expands the air and increases its capacity to absorb and retain moisture, rather than decreasing it. Therefore, only statements 1 and 3 are correct.

Explanation

Statement 1 is correct because oceans cover approximately 71% of the Earth's surface and serve as the primary source of water vapor. Consequently, about 78% of the world's total precipitation occurs over the oceans compared to only 22% over landmasses.

Statement 2 is correct because the eastern margins of continents between 25° and 40° North and South latitudes are influenced by onshore trade winds. These winds blow over warm ocean currents, such as the Gulf Stream in the Northern Hemisphere, carrying significant moisture. This results in heavy rainfall along the eastern coasts, which decreases toward the west.

Explanation

The salinity of ocean water is primarily determined by the balance between the addition of fresh water and the loss of water through evaporation. Evaporation removes pure water, leaving salts behind and thereby increasing salinity, while precipitation adds fresh water, which dilutes the ocean water and decreases salinity. Rivers continuously discharge fresh water into the oceans, significantly lowering the salinity in coastal areas and near river mouths. Ocean currents play a vital role by transporting water masses of different salinity levels across the globe, thereby redistributing salt and modifying the spatial distribution of salinity in different parts of the oceans.

Explanation

Ocean water is dynamic and exhibits both horizontal and vertical movements. Horizontal movements are represented by waves and ocean currents, which transport massive volumes of water across the globe. Vertical movements occur through tides, the sinking of cold, dense surface water, and the upwelling of subsurface water.

This mobility is not driven solely by external forces like wind, solar heating, and gravitational pull. It is also significantly influenced by internal characteristics of the water itself, such as density gradients caused by differences in temperature and salinity, which drive global thermohaline circulation.

Explanation

Sikkim is surrounded by three international borders: Nepal to its west, China (Tibet Autonomous Region) to its north and northeast, and Bhutan to its east.

Tripura is bordered by Bangladesh on three sides—specifically to its north, south, and west. Only its eastern side connects with the rest of India via the states of Assam and Mizoram.

Explanation

The Tapi River originates in the Betul district of Madhya Pradesh and flows westward through a rift valley. The Satpura Range is situated immediately north of the Tapi River valley, meaning the river flows south of this mountain range.

The Tapi is not the only peninsular river flowing from east to west, as the Narmada River, Sabarmati, and Mahi also flow in this direction. Additionally, the Ajanta and Satmala mountain ranges lie to the south of the Tapi River basin in Maharashtra, rather than to its north.

Explanation

The official GPSC answer key marks option (D) "1, 2 and 3" as correct for this question, i.e., all three statements are treated as correct by the examiners. Statement 2 (width of the Himalayas decreases from west to east, from about 400 km in Kashmir to 150 km in Arunachal Pradesh) is standard, undisputed geography. Statements 1 and 3, though debatable by strict geographic convention (the range is more commonly said to run from the Indus, not the Satluj, to the Brahmaputra; and many sources instead attribute greater altitudinal diversity to the eastern Himalayas), were evidently intended by the paper-setters to be read as correct, and the printed master key confirms (D) as the intended answer.

Explanation

The Ganga river is formed by the confluence of the Bhagirathi and the Alaknanda rivers at Devprayag. After traversing through the rugged mountainous terrain of the Himalayas, the river Ganga emerges into the Indo-Gangetic plains at Haridwar.

The Yamuna river, which is the longest tributary of the Ganga, originates from the Yamunotri glacier on the western slopes of the Bandarpunch range in the Himalayas. From its source, it flows in a south-southeasterly direction, running parallel to the right bank of the Ganga river for a long distance before finally merging with it at Triveni Sangam in Prayagraj.

Explanation

Western disturbances originate as extra-tropical cyclones in the Mediterranean Sea region, rather than the Caspian Sea. As they travel eastward, they may absorb additional moisture from the Caspian Sea and the Black Sea, but their origin lies in the Mediterranean.

These low-pressure systems are carried eastward across West Asia by the subtropical westerly jet stream, often referred to as the western jet stream. This high-altitude wind current is responsible for bringing these disturbances into the northwestern parts of India, where they cause crucial winter rainfall and snowfall in the Himalayan region.

Explanation

Tropical evergreen forests in India are restricted to areas receiving heavy annual rainfall, typically exceeding 200 cm, and having a brief dry season. Due to these climatic requirements, they are prominently found in the Andaman and Nicobar Islands and the hills of the north-eastern region, as well as the windward western slopes of the Western Ghats. These forests maintain a warm, humid climate year-round, supporting a dense, multi-layered canopy where different tree species shed their leaves at different times, giving the forest a permanently green appearance.

Explanation

Red soil develops on crystalline igneous rocks in areas of low rainfall, particularly in the eastern and southern parts of the Deccan Plateau. The characteristic reddish colour of this soil is due to the wide diffusion of iron in crystalline and metamorphic rocks. When these iron oxides get hydrated, the soil undergoes a chemical change and appears yellow, which is why they are often collectively referred to as red and yellow soils.

Explanation

The Peninsular Block of India is one of the oldest and most stable landmasses on Earth, formed essentially by a great complex of ancient crystalline igneous and metamorphic rocks. The core and basement of this shield are dominated by Archean gneisses and granites, which have undergone intense metamorphism and deformation over billions of years. Famous examples of these basement rocks include the Bundelkhand gneiss, Bengal gneiss, and various granite suites that cover vast stretches of the southern and eastern parts of the peninsula.

Explanation

India is endowed with abundant resources of high-grade iron ore, particularly hematite and magnetite, which feature high metal content often exceeding 60% to 70% in quality deposits. While magnetite is the finest quality iron ore with the highest iron content, hematite is the most important industrial iron ore in terms of the actual volume and quantity utilized. Due to its massive scale of occurrence and ease of reduction in blast furnaces, hematite is consumed in the largest quantities by the metallurgical and steel industries.

Explanation

The Austro-Asiatic language family, also referred to as the Austric family, represents the oldest known language group in India. Archaeological, genetic, and linguistic studies indicate that the speakers of these languages were the earliest established settlers in the Indian subcontinent, having migrated and settled long before other language groups. In India, this family is primarily represented by the Munda branch (including languages like Santali, Mundari, and Ho spoken in the Chota Nagpur Plateau) and the Mon-Khmer branch (such as the Khasi language in Meghalaya and Nicobarese in the Nicobar Islands). These indigenous languages have deep prehistoric roots in the subcontinent, making them the oldest linguistic stratum of India.

Explanation

The Indian Constitution came into full force and was implemented on 26th January 1950, which is celebrated as Republic Day to mark the birth of the Republic of India.

The Indian Constitution is the longest written constitution of any sovereign country in the world. At its inception, it contained 395 articles in 22 parts and 8 schedules, a size necessitated by the country's vast diversity, federal structure, and detailed administrative provisions.

Explanation

The Preamble to the Indian Constitution declares India to be a Sovereign, Socialist, Secular, Democratic Republic. These terms outline the core philosophy and character of the Indian state.

The Preamble is non-justiciable in nature, meaning its provisions cannot be enforced in a court of law. It serves as an aid to interpret the Constitution but does not grant any independent, enforceable rights or powers.

The Indian Constitution provides for a single citizenship for the entire nation. Unlike other federal nations like the United States where citizens hold dual citizenship of both the state and the nation, Indian citizens owe allegiance only to the Union of India, fostering unity and national integration.

Explanation

The Indian Constitution establishes a dual polity consisting of the Union at the Centre and the States at the periphery, each endowed with sovereign powers to be exercised in the field assigned to them by the Constitution. This constitutes its federal character. At the same time, it possesses strong unitary or non-federal features, such as a strong Centre, a single Constitution, single citizenship, flexibility of the Constitution, an integrated judiciary, appointment of State Governors by the Centre, all-India services, and emergency provisions. Consequently, the Indian Constitution is best described as a federal system with unitary features, or a quasi-federal system.

Furthermore, under Article 37, the Directive Principles of State Policy are explicitly declared as non-justiciable and are not enforceable by any court of law.

Additionally, the Parliament's power to amend the Constitution, including Fundamental Rights, under Article 368 is not absolute and is restricted by the basic structure doctrine formulated by the Supreme Court in the Kesavananda Bharati case in 1973.

Explanation

The 42nd Constitutional Amendment Act, 1976 is called the 'Mini-Constitution' because of the wide-ranging and comprehensive amendments it made to various parts of the Constitution of India. Among other key changes, it amended the Preamble to add the words "Socialist", "Secular", and "Integrity".

The 44th Constitutional Amendment Act, 1978 restored and strengthened several democratic and fundamental rights that were curtailed during the Emergency of 1975–1977. Key restorations included ensuring that the right to life and personal liberty (Article 21) and protection against conviction for offences (Article 20) cannot be suspended during a National Emergency.

The 73rd Constitutional Amendment Act, 1992 provided constitutional recognition to Panchayati Raj Institutions, which are rural local bodies, by introducing Part IX and the Eleventh Schedule to the Constitution. It was the 74th Constitutional Amendment Act, 1992 that granted constitutional status to urban local bodies (Municipalities) by adding Part IX-A and the Twelfth Schedule.

Thus, statements 1 and 2 are correct.

Explanation

The Supreme Court of India introduced the Basic Structure Doctrine in the landmark Kesavananda Bharati v. State of Kerala case (1973). This ruling established that while Parliament has the power to amend the Constitution under Article 368, it cannot alter, destroy, or abrogate its basic structure or essential features. Subsequently, in the S.R. Bommai v. Union of India case (1994), the Supreme Court reinforced this doctrine by explicitly declaring secularism to be an essential and basic feature of the Indian Constitution.

Explanation

The Indian Constitution is described as quasi-federal by constitutional expert K.C. Wheare because of its strong centralizing tendencies and unitary bias, such as the power of the Centre to appoint governors and emergency provisions.

The Seventh Schedule of the Indian Constitution under Article 246 provides a clear demarcation of legislative powers between the Union and the States by classifying subjects into three distinct lists: the Union List (List I), the State List (List II), and the Concurrent List (List III).

The Government of India Act, 1935 served as the administrative blueprint for the post-independence Indian polity. It proposed an All-India Federation and divided legislative powers into Federal, Provincial, and Concurrent lists, thereby laying the structural and federal foundation for the distribution of powers in the Indian Constitution.

Explanation

A quasi-judicial body is an entity, such as a tribunal or commission, whose powers and procedures resemble those of a court of law, requiring it to adjudicate disputes or conduct inquiries and arrive at decisions affecting the rights of parties.\n\nThe Election Commission of India, established under Article 324 of the Constitution, acts in a quasi-judicial capacity while adjudicating disputes relating to recognition of political parties, allotment of symbols, and disputes over splits or mergers, and while advising the President/Governors on disqualification of legislators.\n\nThe National Green Tribunal, set up under the National Green Tribunal Act, 2010, is a specialised tribunal that adjudicates environmental disputes and passes binding orders, making it quintessentially quasi-judicial in character, even though it is a statutory (not constitutional) body.\n\nThe Central Vigilance Commission, established under the Central Vigilance Commission Act, 2003, exercises quasi-judicial powers while conducting inquiries into corruption complaints against public servants, including the powers of a civil court to summon witnesses and examine evidence.\n\nThe Finance Commission, though a constitutional body under Article 280, is essentially an advisory/recommendatory body. Its recommendations on devolution of taxes are not binding, and although the Finance Commission (Miscellaneous Provisions) Act, 1951 grants it civil-court-like powers for gathering evidence, it does not adjudicate disputes or issue binding decisions, so it is not considered a quasi-judicial body.\n\nHence, the Election Commission, the National Green Tribunal, and the Central Vigilance Commission (1, 3 and 4) are quasi-judicial bodies, while the Finance Commission is not.

Explanation

The National Green Tribunal (NGT) is a specialized statutory body established in 2010 under the National Green Tribunal Act, 2010. It was created for the effective and expeditious disposal of cases relating to environmental protection, conservation of forests and other natural resources, and the enforcement of any legal right relating to the environment. The tribunal has dedicated jurisdiction over environmental disputes and operates on the principles of natural justice rather than being bound by the strict procedure laid down under the Code of Civil Procedure, 1908.

Explanation

Article 72 of the Constitution of India empowers the President to grant pardons, reprieves, respites, or remissions of punishment, or to suspend, remit, or commute the sentence of any person convicted of any offense in three specific categories of cases.

First, this power applies in all cases where the punishment or sentence is for an offense against any law relating to a matter to which the executive power of the Union extends, which directly covers offenses against laws made by Parliament.

Second, the power extends to all cases where the punishment or sentence is by a Court Martial, which encompasses offenses committed by members of the armed forces tried under military law.

Third, the President possesses this power in all cases where the sentence is a sentence of death, making the President the ultimate authority to grant pardons in death penalty cases.

Explanation

The 73rd Constitutional Amendment Act of 1992 and the 74th Constitutional Amendment Act of 1992 established the constitutional foundation for local self-governance in India. The 73rd Amendment Act introduced Part IX to the Constitution, titled The Panchayats, along with the Eleventh Schedule, which lists 29 functional items to empower rural local bodies. The 74th Amendment Act introduced Part IXA, titled The Municipalities, along with the Twelfth Schedule, which lists 18 functional items for urban local bodies. These amendments institutionalized a democratic framework for decentralized administration, ensuring mandatory regular elections, the setting up of State Finance Commissions, and the reservation of seats for scheduled castes, scheduled tribes, and women at the grassroots level.

Explanation

The Digital India Mission and the Direct Benefit Transfer (DBT) Scheme are directly aimed at improving governance, public service delivery, and administrative efficiency at both the state and central levels.

The Digital India Mission is a flagship program designed to transition the country into a digitally empowered society and knowledge economy. By improving digital infrastructure, enhancing connectivity, and ensuring that government services are electronically accessible to citizens, it promotes e-governance and reduces administrative bottlenecks.

Similarly, the Direct Benefit Transfer (DBT) Scheme is a landmark governance reform that restructures the government delivery system. By transferring subsidies and benefits directly into the bank accounts of beneficiaries, it eliminates intermediaries, curtails leakages, and enhances transparency and financial accountability across central and state-level welfare programs.

In contrast, the Smart Cities Mission is primarily focused on urban renewal, sustainable town planning, and infrastructure development. The Pradhan Mantri Awas Yojana (PMAY) is a targeted social housing welfare program aimed at providing affordable housing to the economically weaker sections.

Explanation

Public Interest Litigation (PIL) was introduced in India by relaxing the traditional rule of locus standi, allowing any public-spirited individual, NGO, or activist to file petitions on behalf of marginalized or affected communities who are unable to approach the court themselves. It aims to secure social justice and ensure legal representation for economically weaker and socially disadvantaged sections of society. Under this mechanism, courts also have the power to take suo motu cognizance of issues affecting the public interest based on letters, postcards, or media reports. This process significantly expanded judicial activism and access to justice, rather than restricting the power of the judiciary.

Explanation

The doctrine of collective responsibility is a fundamental pillar of the parliamentary system of government in India.

Under Article 75(3) of the Indian Constitution, the Union Council of Ministers is collectively responsible to the House of the People (Lok Sabha). Similarly, at the state level, Article 164(2) stipulates that the State Council of Ministers is collectively responsible to the Legislative Assembly of the State. This establishes that the doctrine applies to both levels of government, making statement 4 correct and statement 1 incorrect.

Collective responsibility implies that all cabinet decisions bind all ministers. Even if a minister disagrees with a decision during cabinet discussions, they must defend and publicly support that decision once it is collectively agreed upon. If a minister is unable to support a cabinet decision publicly, they are expected to resign. This makes statement 2 correct.

Statement 3 describes the doctrine of individual responsibility, which is distinct from collective responsibility. Under Article 75(2), ministers hold office during the pleasure of the President, which allows the President to dismiss an individual minister on the advice of the Prime Minister, even if the Council of Ministers still commands the confidence of the Lok Sabha.

Explanation

Judicial activism refers to the proactive role played by the judiciary in protecting the rights of citizens and promoting justice, often by intervening in legislative and executive domains when they fail to discharge their constitutional duties. This philosophy gained massive momentum in India during the late 1970s and 1980s through the introduction of Public Interest Litigation, spearheaded by judicial pioneers like Justice P. N. Bhagwati and Justice V. R. Krishna Iyer. Under the power of judicial review, which is an integral part of judicial activism, the Supreme Court can strike down any legislative enactment or executive action that violates the Basic Structure of the Constitution. The Kesavananda Bharati Case of 1973 formulated the Basic Structure doctrine, but it did not explicitly define or establish judicial activism as a constitutional doctrine, making the fourth statement incorrect.

Explanation

Central Administrative Tribunal is a quasi-judicial body established under Article 323A of the Constitution of India. It is specifically mandated to adjudicate disputes, grievances, and complaints relating to the recruitment and conditions of service of persons appointed to public services and posts in connection with the affairs of the Union or other public authorities.

Competition Commission of India is a statutory body established under the Competition Act, 2002. It acts as a quasi-judicial regulator responsible for preventing practices that have an appreciable adverse effect on competition, protecting consumer interests, and regulating monopolistic trade practices and abuse of dominant position in the Indian market.

Explanation

Ministry of External Affairs (MEA) is the primary government ministry responsible for managing India's foreign relations, formulating foreign policy, and representing India in bilateral and multilateral forums.

Research and Analysis Wing (RAW) is the foreign intelligence agency of India, which plays a critical role in safeguarding national security and shaping foreign policy by collecting intelligence and countering external threats.

Indian Council for Cultural Relations (ICCR) is an autonomous body under the administrative control of the MEA, dedicated to promoting India's cultural relations with other countries, enhancing soft power through cultural exchange programs, scholarships, and academic collaborations.

Explanation

Article 50 of the Constitution of India explicitly mandates the separation of the judiciary from the executive in the public services of the State, which is a fundamental directive principle ensuring judicial independence and preventing executive interference in judicial functions.

Article 123 deals with the ordinance-making power of the President, allowing the executive head to legislate when Parliament is not in session. This represents a functional overlap where the executive exercises legislative powers, directly interacting with the principle of horizontal separation of powers and the system of checks and balances.

Article 246 delineates the subject-matter jurisdiction and competence of the legislative organ to make laws, which establishes the constitutional boundaries and scope of the legislature's authority in relation to other branches of government.

Explanation

Under Article 243K and Article 243ZA of the Constitution of India, State Election Commissions are vested with the powers of superintendence, direction, and control of the preparation of electoral rolls for, and the conduct of, all elections to the Panchayati Raj institutions and Municipal bodies. Additionally, Article 243K(2) mandates that the conditions of service and tenure of office of the State Election Commissioner shall be such as the Governor of the state may by rule determine, subject to the provisions of any law made by the State Legislature. This establishes the constitutional authority, the functional domain, and the administrative framework governing the tenure and service conditions of the State Election Commissioners.

Explanation

The 2008 Indo-US civil nuclear agreement, also known as the 123 Agreement, was highly controversial for several reasons. It allowed India to engage in international civil nuclear trade by securing a unique waiver from the Nuclear Suppliers Group, even though India remained a non-signatory to the Non-Proliferation Treaty. Additionally, domestic critics argued that the deal infringed upon India's sovereignty, as the accompanying US Hyde Act stipulated that nuclear cooperation would cease if India conducted any future nuclear tests. This intense political disagreement led the Left Front to withdraw its support from the ruling United Progressive Alliance coalition, forcing the government to seek and win a historic vote of confidence in Parliament in July 2008 to prove its majority.

Explanation

India is characterized as a quasi-federal state because it has a federal structure with a pronounced centralizing bias, combining features like a written Constitution and dual polity with unitary characteristics such as a single citizenship and emergency powers. The legislative powers are systematically distributed between the Centre and the States through the Seventh Schedule of the Constitution, which classifies subjects into the Union List, State List, and Concurrent List. Furthermore, Article 280 of the Constitution provides for a Finance Commission to serve as a quasi-judicial body that recommends the sharing of financial resources, particularly the devolution of tax revenues and grants-in-aid, between the Union and the States to maintain fiscal federalism.

Explanation

The First Constitutional Amendment Act of 1951 amended Article 19, introducing three additional reasonable restrictions on the freedom of speech and expression, specifically public order, friendly relations with foreign states, and incitement to an offence, while making these restrictions justiciable. The 42nd Amendment Act of 1976, enacted during the Emergency, is widely referred to as the Mini-Constitution because it brought about massive and sweeping changes to a large number of provisions in the Constitution. The 44th Amendment Act of 1978 was subsequently enacted to undo many of the controversial modifications made by the 42nd Amendment, thereby restoring crucial democratic and fundamental rights safeguards, such as ensuring that Articles 20 and 21 cannot be suspended even during a National Emergency. The 101st Amendment Act of 2016 facilitated the implementation of the Goods and Services Tax (GST) in India, introducing a comprehensive indirect tax regime across the nation.

Explanation

Article 124 of the Constitution of India governs the establishment and constitution of the Supreme Court of India.

The High Courts of India function under Articles 214 to 231, which are contained in Chapter V of Part VI of the Constitution.

The Supreme Court, in the Fourth Judges Case in 2015, struck down the 99th Constitutional Amendment Act and the National Judicial Appointments Commission (NJAC) Act, declaring them unconstitutional as they compromised the independence of the judiciary, which is an essential part of the basic structure of the Constitution.

Under Article 124(2) of the Constitution, the Chief Justice of India is appointed by the President of India after consultation with such judges of the Supreme Court and the High Courts as the President may deem necessary, and in practice, based on the recommendation of the outgoing Chief Justice of India under the Collegium system, rather than in consultation with the Council of Ministers.

Explanation

The Government of India Act, 1935 introduced provincial autonomy by abolishing the system of diarchy at the provincial level and replacing it with responsible government, allowing provinces to act as autonomous units of administration in their defined spheres.

The Act also proposed the creation of an All-India Federation consisting of British Indian provinces and princely states as units. This federation never materialized because the requisite number of princely states chose not to join it.

Additionally, the Act provided for the establishment of a Federal Court of India to resolve disputes between provinces and between the center and provinces. This court was subsequently set up in Delhi in 1937.

Explanation

The Balwant Rai Mehta Committee, appointed in 1957, recommended the establishment of a three-tier Panchayati Raj system comprising Gram Panchayats at the village level, Panchayat Samitis at the block level, and Zilla Parishads at the district level.

The 73ʳᵈ Constitutional Amendment Act, 1992, constitutionalised this structure, mandating the establishment of three-tier Panchayati Raj institutions in all states with a population exceeding 20 lakh.

The 11ᵗʰ Schedule of the Constitution lists 29 functional items concerning the powers, authority, and responsibilities of these local bodies.

The State Election Commission is exclusively responsible for conducting elections to local bodies like Panchayats and Municipalities, whereas elections to the State Legislatures and Parliament are conducted by the Election Commission of India.

Explanation

Article 13 of the Indian Constitution explicitly establishes the doctrine of judicial review by declaring all laws inconsistent with or in derogation of fundamental rights to be null and void. The Supreme Court under Article 32 and High Courts under Article 226 are empowered to review the constitutional validity of both legislative enactments and constitutional amendments. In the historic Kesavananda Bharati v. State of Kerala case (1973), a 13-judge bench of the Supreme Court ruled that while Parliament has wide powers to amend the Constitution under Article 368, these powers do not extend to altering, destroying, or damaging its basic structure.

Explanation

Commercial passenger jets fly at cruising altitudes of approximately 30,000 to 42,000 feet, which aligns precisely with the altitude of jet streams. These high-speed, high-altitude wind currents generally flow from west to east. By planning routes that enter these streams when traveling eastward, commercial passenger jets utilize the powerful tailwinds to significantly increase their ground speed. This reduction in flight duration translates directly into substantial fuel savings and lower operational costs for long-haul commercial flights, making them the primary beneficiaries of this meteorological phenomenon.
