UPPSC Prelims 2024 Question Paper with Answers & Explanations

Explanation

Kanchipuram (A) corresponds to the Ancient Period (4) as it was a major religious and political center during the Pallava era from the 4th century onwards. Jaisalmer (B) belongs to the Medieval Period (3) since it was founded in 1156 AD as a fortified Rajput city. Kodaikanal (C) represents the Colonial Period (2) because it was established as a hill station in 1845 by British officials and American missionaries. Bhilai (D) is a Post-independence (1) planned city, developed specifically as an industrial hub following the setup of the Bhilai Steel Plant in 1955.

Explanation

Mango shower matches with Karnataka Coastal Areas as these pre-monsoon rains help in the early ripening of mangoes in the region. Blossom shower matches with Kerala because these rains are crucial for the blossoming of coffee flowers. Norwesters match with West Bengal where they are known as Kalbaisakhi and involve severe thunderstorms during the spring. Loo matches with the region from Punjab to Bihar, describing the hot, dry summer winds characteristic of the North Indian plains.

Explanation

Khartoum is the capital and largest city of Sudan, situated at the geographical convergence of the White Nile and the Blue Nile. The capital city of Ethiopia is Addis Ababa, which also serves as the headquarters for the African Union. Therefore, the association of Khartoum with Ethiopia is geographically and politically inaccurate.

Explanation

FLY91 is a regional airline based in Goa, promoted by Just Udo Aviation Private Limited, which received its Air Operator Certificate from the Directorate General of Civil Aviation in March 2024. As a new entrant in the Indian aviation market, it aims to enhance regional connectivity under the government's UDAN scheme. The airline officially commenced its commercial operations on March 18, 2024, with its inaugural flight departing from Manohar International Airport at Mopa, Goa, destined for Agatti in Lakshadweep. The carrier utilizes a fleet of ATR 72-600 aircraft to connect Tier 2 and Tier 3 cities across the country.

Explanation

According to the 2011 Census of India, the states listed follow a specific hierarchy in terms of total population. Uttar Pradesh is the most populous state in the country with approximately 19.98 crore residents. Bihar follows as the third most populous state in India (after Maharashtra) with a population of approximately 10.41 crore. West Bengal ranks fourth nationally with a population of about 9.13 crore. Andhra Pradesh, considering its undivided boundaries as per the 2011 Census data, had a population of approximately 8.46 crore, placing it fifth in the national ranking. Consequently, the descending order of these states by population is Uttar Pradesh (3), Bihar (1), West Bengal (4), and Andhra Pradesh (2).

Explanation

The Human Development Report is a flagship publication of the United Nations Development Programme (UNDP), first launched in 1990 to assess global progress through the lens of human capabilities rather than just economic growth. The World Economic Outlook is released twice a year by the International Monetary Fund (IMF), providing comprehensive analysis and projections for global economic growth, inflation, and trade. The World Investment Report is an annual publication by the United Nations Conference on Trade and Development (UNCTAD) that tracks global trends in foreign direct investment and analyzes the impact of international investment policies. The Emissions Gap Report is published annually by the United Nations Environment Programme (UNEP), serving as a scientific assessment of the gap between anticipated greenhouse gas emissions and the levels required to limit global warming to 1.5 degrees Celsius or 2 degrees Celsius.

Explanation

The correct chronological sequence is determined by the launch dates of these social welfare and employment schemes. Prime Minister Rozgar Yojana (PMRY) was initiated on October 2, 1993, with the goal of providing self-employment to educated unemployed youth. The Rural Employment Generation Programme (REGP) was launched in April 1995 by the Khadi and Village Industries Commission to generate employment in rural areas and small towns. Pradhan Mantri Gramodaya Yojana (PMGY) was introduced during the 2000-01 financial year to focus on rural development through five critical sectors including health, education, and housing. Finally, the Valmiki Ambedkar Awas Yojana (VAMBAY) was launched in December 2001 to provide shelter and improve the living conditions of urban slum dwellers. This yields the sequence 3, 2, 1, and 4.

Explanation

Gunnar Myrdal is the author of Economic Theory and Under-developed Regions (1), a 1957 work that critiques static equilibrium theory and introduces the principle of circular cumulative causation to explain regional inequalities. Albert O. Hirschman wrote The Strategy of Economic Development (2) in 1958, where he proposed the theory of unbalanced growth and emphasized the importance of investment linkages in the development process. Nicholas Kaldor authored Strategic Factors in Economic Development (3) in 1967, focusing on the role of industrialization and the manufacturing sector as the primary driver of rapid economic growth. Adam Smith published An Inquiry into the Nature and Causes of the Wealth of Nations (4) in 1776, which is the fundamental text of classical economics detailing the division of labor and the function of free markets.

Explanation

The number of species in an ecosystem is positively correlated with resource availability and niche variety. When resources are sufficient and equitably distributed, the ecosystem can support a greater diversity of organisms, leading to an increase in the total number of species rather than a decrease. Resource abundance facilitates niche partitioning, where different species adapt to utilize specific portions of the available resources, thereby reducing direct competition and allowing a larger biological community to thrive. Consequently, the assertion that a sufficient resource supply leads to a small number of species is ecologically inaccurate.

Explanation

Simlipal Biosphere Reserve is located in the Mayurbhanj district of Odisha and is renowned for its tiger population and vast expanses of sal forests. Nokrek Biosphere Reserve is situated in the West Garo Hills of Meghalaya and serves as a critical habitat for the endangered Red Panda and various citrus species. Agasthyamalai Biosphere Reserve is positioned at the southern end of the Western Ghats, encompassing regions in Kerala and Tamil Nadu, and is known for its high level of endemism and medicinal plants. Manas Biosphere Reserve is located in the foothills of the Himalayas in Assam and is recognized as a UNESCO World Heritage site for its unique biodiversity, including the pygmy hog and the wild water buffalo. The correct matching sequence is A-2, B-4, C-1, and D-3.

Explanation

Scientific investigation is inherently tied to practical ideals such as objectivity, systematic observation, and the rigorous application of the scientific method. These ideals serve as a normative framework that guides researchers in gathering data, testing hypotheses, and ensuring that their results are verifiable and relevant to the physical world. Without a commitment to these practical standards, inquiry would deviate into mere speculation rather than grounded scientific knowledge.

Honesty is equally indispensable because science is a cumulative and collaborative enterprise. The scientific community relies on the integrity of shared data to build new theories and conduct further experiments. If honesty is compromised through the fabrication or falsification of results, the process of peer review and reproducibility—the self-correcting mechanisms of science—fails. Therefore, maintaining high ethical standards of honesty is critical for the credibility of research and the overall progress of human knowledge.

Explanation

The taxonomic hierarchy is a standardized system used in biological classification to organize living organisms into successive levels based on their complexity and shared characteristics. This hierarchy proceeds from the most inclusive rank to the most specific. At the highest level is the Kingdom, which for plants is the Plant Kingdom. This is followed by the Phylum, a major grouping that defines the body plan of the organisms within the kingdom. Below the Phylum is the Class, which further categorizes organisms based on more distinct shared features. Next in descending order is the Order, which consists of families that share even more specific traits. This sequence accurately represents the transition from a broad ecological group to increasingly refined biological categories.

Explanation

The Justice Party, officially known as the South Indian Liberal Federation, was formed in 1916 by leaders like T.M. Nair and P. Theagaraya Chetty to represent the interests of non-Brahmins in the Madras Presidency. It consistently opposed the Indian National Congress, characterizing it as a vehicle for Brahmin interests and arguing that Congress-led movements like the Home Rule League were designed to establish Brahmin supremacy over the non-Brahmin majority.

The party sought to counter this perceived domination by demanding institutional safeguards through communal representation. Drawing a direct parallel to the Morley-Minto Reforms of 1909, which had granted separate electorates to Muslims, the Justice Party petitioned the British government for similar communal reservations. They argued that without such protections, the numerically superior but socially and educationally disadvantaged non-Brahmin communities would remain excluded from the administrative and legislative processes. This sustained political pressure eventually led to the provision of reserved seats for non-Brahmins in the Madras Presidency under the Government of India Act 1919.

Explanation

The Workers and Peasants Party (WPP) was established as a legal political platform for the then-illegal Communist Party of India to carry out its activities. By 1927, the party had strengthened its provincial units in Bombay, Bengal, Punjab, and the United Provinces, effectively taking the shape of an All India organization to coordinate radical activities across the country. The primary political objective of the WPP was to function as a revolutionary left-wing bloc within the Indian National Congress. Members sought to radicalize the Congress from the inside, pushing the leadership to adopt the goal of complete independence (Purna Swaraj) and to transform the organization into a mass-based revolutionary party that represented the socio-economic interests of the common people, specifically the industrial workers and the peasantry.

Explanation

The chronological sequence begins with the East India Association, founded by Dadabhai Naoroji in London in 1866 to discuss the Indian question and influence British public opinion. This was followed by the National Indian Association, established by Mary Carpenter in 1870 to promote social reform and cooperation between Indians and the British. The Indian Society was subsequently formed by Anand Mohan Bose in London in 1872 to foster a sense of brotherhood and political consciousness among Indians living in Britain. Lastly, the Indian Association was founded by Surendranath Banerjee and Anand Mohan Bose in Calcutta in 1876 as a major political organization to unify people on a common political program and agitate for civil rights. This results in the sequence 1866, 1870, 1872, and 1876.

Explanation

The UK Parliamentary Delegation, led by Robert Richards, arrived in India on January 5, 1946, to study the political situation and meet with Indian leaders. The Royal Indian Navy (RIN) Revolt began on February 18, 1946, when ratings of the HMIS Talwar in Bombay went on strike to protest against racial discrimination and poor food. British Prime Minister Clement Attlee announced the dispatch of the Cabinet Mission to India on February 19, 1946, in the House of Commons, largely as a response to the growing unrest exemplified by the naval mutiny. The Interim Government of India was eventually formed on September 2, 1946, with Jawaharlal Nehru serving as the Vice-President of the Executive Council.

Explanation

Behramji Malabari, a Parsi social reformer from Bombay, was the central figure in the movement that led to the Age of Consent Act of 1891. Through his publication of Notes on Infant Marriage and Enforced Widowhood in 1884 and his persistent lobbying of both the British public and the colonial administration, he highlighted the physical and social dangers of early marriage. His efforts were instrumental in pressuring the government to raise the age of consent for girls from 10 to 12 years.

Bal Gangadhar Tilak and the extremist wing of the nationalist movement strongly opposed the Act. Tilak argued that a foreign, colonial government had no right to interfere in the domestic religious and social customs of Indians. He believed that social reforms should originate from within the community through education and self-awakening rather than being imposed by the British state. This opposition turned the debate over the Act into a major political confrontation between social reformers and orthodox nationalists.

Explanation

Shivaji’s efforts to establish Swarajya faced significant internal resistance from powerful hereditary landed elites known as Deshmukhs. Chieftains such as the Morays of Javali, the Ghorpades of Mudhol, and the Savants of Wadi were entrenched in the socio-political hierarchy of the Deccan. These Deshmukhs held their ancestral land grants (watans) as vassals of the Adil Shahi Sultanate of Bijapur. They viewed Shivaji’s rise as a threat to their traditional privileges and local autonomy. Since the Bijapur Sultanate provided legal legitimacy to their feudal status and largely allowed them to function as independent lords within their territories, they were reluctant to support a centralized Maratha state. Shivaji’s vision required these lords to subordinate their private interests to the cause of a sovereign state, which directly contradicted their desire to remain feudal intermediaries under the existing Bijapur administration. This conflict of interest made their loyalty to Bijapur the primary driver of their opposition to Shivaji.

Explanation

Coral bleaching in the Andaman and Nicobar Islands is primarily driven by thermal stress resulting from marine heatwaves. Corals maintain a symbiotic relationship with microscopic algae called zooxanthellae, which provide them with nutrients and their vibrant colors. When the sea surface temperature in the Indian Ocean rises by approximately 2°C above the normal summer maximum and remains elevated for a prolonged period, the corals undergo intense physiological stress. This stress causes the coral polyps to expel the zooxanthellae, leading to a white, bleached appearance. Without these algae, the corals lose their primary energy source and become highly susceptible to disease and starvation. Sustained temperature anomalies of this magnitude, often exacerbated by global warming and El Nino events, lead to the catastrophic mass mortality of reef systems across the archipelago.

Explanation

Ashoka introduced a new class of high-ranking officials called Dhamma-mahamatras in the 14th year of his reign, which corresponds to the period after he had been consecrated for thirteen years. As recorded in Major Rock Edict V, these officials were tasked with propagating the principles of Dhamma and ensuring the welfare and happiness of his subjects across all religious sects, including Brahmanas, Shramanas, and the destitute. Their responsibilities also included overseeing the justice system to prevent wrongful imprisonment and supervising the distribution of charities throughout the empire.

Explanation

Article 155 of the Constitution of India provides for the appointment of the Governor, stating that the Governor of a State shall be appointed by the President by warrant under his hand and seal. The provisions regarding the removal of the Governor are not contained in Article 155; instead, Article 156(1) specifies that the Governor shall hold office during the pleasure of the President, which encompasses the power of removal. Because Article 155 is exclusively dedicated to the appointment process, matching it with the removal of the Governor is constitutionally incorrect.

Explanation

Article 59(1) of the Constitution of India explicitly states that the President shall not be a member of either House of Parliament or of a House of the Legislature of any State. This provision ensures the independence of the executive head and mandates that if a member of any House is elected as President, they are deemed to have vacated their seat upon entering office. Additionally, Article 79 defines the composition of the Parliament, stating that there shall be a Parliament for the Union which shall consist of the President and two Houses, to be known respectively as the Council of States and the House of the People. Although the President is not a member of either House and does not participate in the proceedings of Parliament, they are an integral part of the legislative process as no bill passed by both Houses can become law without the President's assent.

Explanation

According to Article 368 of the Indian Constitution, an amendment can be initiated only by the introduction of a Bill for the purpose in either House of Parliament, namely the Lok Sabha or the Rajya Sabha. The Constitution does not provide for the initiation of constitutional amendments by the State Legislatures or the President of India. A Bill for amendment can be introduced either by a Minister or by a private member and does not require the prior recommendation of the President. While certain amendments affecting the federal structure require ratification by at least half of the State Legislatures, the formal process of initiation remains strictly within the domain of the two Houses of Parliament.

Explanation

The Election Commission of India derives its powers from Article 324 of the Constitution, which limits its jurisdiction to the conduct of elections for the Parliament, the State Legislatures, and the offices of the President and Vice-President. The elections for the Speaker and Deputy Speaker of the Lok Sabha and the Deputy Chairman of the Rajya Sabha are internal parliamentary procedures managed by the respective houses rather than the Election Commission. Similarly, elections for local bodies such as Municipal Corporations and Municipalities fall under the exclusive jurisdiction of the State Election Commissions as per Articles 243K and 243ZA. Disputes and doubts arising from elections are also not decided by the Election Commission; for instance, Article 71 stipulates that the Supreme Court resolves disputes regarding Presidential and Vice-Presidential elections, while the High Courts adjudicate disputes regarding elections to Parliament and State Legislatures through election petitions.

Explanation

Biotic succession follows a systematic progression starting with the arrival of organisms in a bare area and ending in a stable community. The process begins with Migration, which is the dispersal of seeds, spores, or other propagules to a new site. This is followed by Ecesis, the stage where these propagules successfully germinate, grow, and establish themselves in the environment. Once established, the organisms interact with their surroundings and each other, leading to Reaction, where the existing species modify the physical environment, such as soil composition or microclimate. These modifications often make the habitat more suitable for new species while becoming less favorable for the current occupants. Finally, the community reaches Stabilisation, also known as the climax stage, where a state of equilibrium is achieved with the regional climate, resulting in a persistent and self-perpetuating biological community.

Explanation

Relative humidity is the ratio of the actual amount of water vapor present in the air to the maximum amount of water vapor the air can hold at a specific temperature. The moisture-holding capacity of air is directly dependent on its temperature; as temperature increases, the saturation vapor pressure increases. Consequently, if the actual moisture content remains constant while the temperature rises, the relative humidity decreases. This confirms that Assertion (A) is true.

Absolute humidity refers to the actual mass of water vapor per unit volume of air. Evaporation is the process by which liquid water is converted into water vapor and added to the atmosphere. As evaporation increases, the total mass of water vapor in the air increases, thereby raising the absolute humidity. This confirms that Reason (R) is true. However, the decrease in relative humidity mentioned in the assertion is caused by the change in the air's capacity to hold moisture due to temperature shifts, not by the process of evaporation described in the reason. Therefore, both statements are true, but the reason does not explain the assertion.

Explanation

A pycnocline is a layer in a body of water, such as the ocean, where the water density increases rapidly with depth. Seawater density is determined by the relationship ρ = f(T, S, p), where T is temperature, S is salinity, and p is pressure. The pycnocline represents the region of the greatest vertical density gradient, separating the lower-density surface mixed layer from the higher-density deep ocean water. This stratification acts as a barrier to vertical mixing and the exchange of nutrients and gases between the surface and the deep sea.

Explanation

The Muri alumina refinery is located in the Ranchi district of the state of Jharkhand. Established in 1948 by the Indian Aluminium Company (INDAL) and currently operated by Hindalco Industries Limited, it stands as one of India's oldest alumina refining units. The plant is strategically situated to utilize bauxite ore sourced from the Lohardaga region of Jharkhand. It processes this raw bauxite into alumina, which is then transported to various smelting plants for the production of aluminium metal. Consequently, the pairing of Muri with the state of Chhattisgarh is geographically incorrect as the facility resides entirely within Jharkhand.

Explanation

Pin Valley National Park is located in the Lahaul and Spiti district of Himachal Pradesh, rather than Jammu and Kashmir. Established in 1987, the park is situated in the cold desert habitat of the Spiti Valley within the high Himalayan bio-geographical zone. It is well-known for being a natural habitat for several endangered species, most notably the snow leopard and the Siberian ibex.

Explanation

The Himalayas are the result of an ongoing continent-continent collision between the Indian Plate and the Eurasian Plate. This tectonic process began approximately 50 million years ago following the closure of the Tethys Sea. Because the Indian Plate continues to move northward at a rate of approximately 5 centimeters per year, it exerts immense pressure against the Eurasian Plate. This continuous convergence leads to the crustal thickening and uplift of the mountain range. Modern geodetic measurements using GPS confirm that the Himalayas are still rising at a rate of several millimeters per year. Since the northward movement and resultant subduction-collision process are active, the tectonic pressure directly causes the ongoing vertical growth of the mountains.

Explanation

Hutar coalfield is located in the Latehar district of Jharkhand and belongs to the North Koel valley group of coalfields. Ib River coalfield is situated in the Sambalpur and Jharsuguda districts of Odisha and forms a major part of the Mahanadi basin coal reserves. Tatapani-Ramkola coalfield lies in the Surguja and Balrampur districts of Chhattisgarh. Umaria coalfield is found in the Umaria district of Madhya Pradesh and is categorized under the Son valley coalfields.

Explanation

(A) Upper Bari Doab Canal matches with Ravi (4) because it originates from the Madhopur Headworks on the Ravi river to irrigate the districts of Gurdaspur and Amritsar. (B) Sirhind Canal matches with Sutlej (1) as it is a major irrigation network in Punjab that draws its water from the Sutlej river at the Ropar Headworks. (C) Gurgaon Canal matches with Yamuna (2) because it receives water from the Yamuna river via the Okhla Barrage to serve the needs of Haryana and Rajasthan. (D) Indira Gandhi Canal matches with Sutlej, Ravi, Beas (3) as it starts at the Harike Barrage located at the confluence of the Sutlej and Beas rivers, and its water allocation includes the regulated surplus from the Ravi river system.

Explanation

Bihar contribution to the total rice production of India is approximately 5 to 7 percent. According to the data from the Ministry of Agriculture and Farmers Welfare for recent years, major rice producing states like West Bengal and Uttar Pradesh lead the national production shares, while Bihar usually ranks lower in the hierarchy. For instance, in the 2021-22 and 2022-23 agricultural years, Bihar produced roughly 7 to 8 million tonnes against a national total of over 130 million tonnes. The value of 15.7 percent indicated in the pair is an overestimation and does not reflect the actual statistical contribution of the state to the national rice basket.

Explanation

Cotton is primarily a Kharif crop in India, typically sown between May and July and harvested from October onwards. It requires high temperatures ranging from 21 to 30 degrees Celsius and at least 210 frost-free days to mature. Regarding moisture, cotton is a drought-resistant crop that thrives in semi-arid conditions. It requires a moderate amount of annual rainfall, generally between 50 cm and 75 cm. While it can tolerate up to 100 cm of rain, the distribution is critical, as heavy rainfall or stagnant water during the boll-opening and harvesting stages can damage the fiber. The crop is traditionally grown in the black soil regions of the Deccan Plateau, where the soil's moisture-retention capacity supports growth even with limited rainfall.

Explanation

Red soil is the second largest soil group in India, covering approximately 18.5 percent of the total land area, following Alluvial soil which is the most extensive. This soil develops on crystalline igneous rocks under conditions of low rainfall in the eastern and southern parts of the Deccan Plateau.

Geographically, Red soil is found encircling the Black soil region of the Deccan Trap. It extends along the southern, eastern, and north-eastern fringes of the plateau, covering states such as Tamil Nadu, Karnataka, Andhra Pradesh, Chhattisgarh, and Odisha. While both statements are factually accurate, the geographical position of Red soil relative to Black soil does not explain the reason why Red soil constitutes the second largest soil category in the country. The classification by size is determined by the vast extent of the underlying parent metamorphic and crystalline rocks across the Indian peninsula rather than its proximity to other soil types.

Explanation

Kanchipuram = Ancient (4, ~1st century BCE Pallava capital). Jaisalmer = Medieval (3, founded 1156 CE). Kodaikanal = Colonial (2, developed ~1845). Bhilai = Post-independence (1, steel plant 1955). Code: A-4, B-3, C-2, D-1 = "4 3 2 1" = Option D.

Explanation

Mango shower = Karnataka Coastal Areas (3). Blossom shower = Kerala (2). Norwesters = West Bengal (4). Loo = Punjab to Bihar (1). Code: A-3, B-2, C-4, D-1 = "3 2 4 1" = Option C.

Explanation

Khartoum is the capital city of Sudan, located at the confluence of the White Nile and the Blue Nile. The capital of Ethiopia is Addis Ababa, which serves as the country's political and commercial hub as well as the headquarters of the African Union. Since Khartoum is the administrative center of Sudan and not Ethiopia, this pair is incorrectly matched.

Explanation

The Upper Gangetic Plain region, identified as Zone IV by the Planning Commission, primarily covers thirty-two districts within central and western Uttar Pradesh. This region is characterized by flat topography and highly productive alluvial soils deposited by the Ganga and its tributaries. Due to the extensive development of canal networks and private tubewells, the area enjoys high water availability for agriculture. The irrigation intensity in this zone is reported to be over 130 percent, as a significant portion of the net sown area receives water for more than one crop season. Similarly, the cropping intensity in the Upper Gangetic region is high, typically ranging between 144 percent and 150 percent, as the availability of irrigation allows for multiple cropping cycles, predominantly featuring wheat, rice, and sugarcane. These factors together make it one of the most agriculturally advanced zones in India.

Explanation

Debsa Pass is a high-altitude mountain pass in the Greater Himalayas that connects the Kullu and Spiti districts of Himachal Pradesh, situated at an elevation of 5360 metres. Rohtang Pass is a prominent mountain pass on the eastern Pir Panjal Range of the Himalayas, serving as a gateway between the Kullu Valley and the Lahaul and Spiti Valleys at a height of 3978 metres. Bara-lacha La is a high mountain pass in the Zanskar range that connects Lahaul in Himachal Pradesh to Leh in Ladakh, standing at an altitude of 4850 metres. Banihal Pass is located across the Pir Panjal Range and serves as a vital connection between the Jammu region and the Kashmir Valley, positioned at a height of 2832 metres.

Explanation

Jute is an indigenous plant of the Indian subcontinent, specifically native to the humid regions of the Ganges and Brahmaputra deltas. Botanical evidence and historical records, including ancient Sanskrit texts, confirm that species such as Corchorus capsularis originated in the Indo-Burma region, making Assertion (A) true. Statement (R) is false because Jute is technically classified as a Pre-Kharif or Zaid crop rather than a standard Kharif crop. In the Indian agricultural calendar, the Kharif season officially begins with the onset of the monsoon in June. Jute, however, is predominantly sown between February and May to utilize pre-monsoon showers and ensure the plants are tall enough to withstand the subsequent monsoon floods. While the sowing and harvesting months described are largely accurate for the crop's lifecycle, the seasonal label of Kharif is technically incorrect.

Explanation

Devana Bhatta was a prominent 12th-13th century scholar from South India who authored Smriti Chandrika, a comprehensive work on civil and religious duties that became highly influential in South Indian jurisprudence. Hemadri, a minister in the Yadava court of Devagiri in the 13th century, compiled the Chaturvarga Chintamani, which is an extensive encyclopedic treatise on Dharmashastra covering various aspects of religious observances. Madhvacharya, often identified with the 14th-century scholar Vidyaranya of the Vijayanagara Empire, wrote the Parashar Madhav, an influential commentary on the Parashara Smriti. Ballal Sen, the 12th-century king of the Sena dynasty in Bengal, was the author of Dan Sagar, a celebrated work focusing on the types and merits of religious gifts and charities.

Explanation

The Turkish invasions of India, spearheaded by Mahmud of Ghazni and later Muhammad Ghori, were successful as they led to the eventual establishment of the Delhi Sultanate. The political landscape of North India during the 11th and 12th centuries was characterized by the presence of numerous small, independent Rajput states such as the Chauhans, Gahadvalas, and Kalachuris. These kingdoms were frequently involved in internecine warfare and lacked a centralized authority or a sense of national unity. This fragmentation prevented the Indian rulers from organizing a collective and sustained military resistance against the invaders. The Turks were able to exploit these internal divisions and defeat the regional powers individually. Consequently, the absence of political unity was a fundamental factor that directly facilitated the success of the Turkish military campaigns in the subcontinent.

Explanation

India hosted the 2nd Voice of Global South Summit in a virtual format on November 17, 2023, following the successful conclusion of the first summit in January 2023. This second edition focused on sharing the outcomes of India's G20 Presidency and discussing the challenges faced by developing nations under the theme Together, for Everyone's Growth, with Everyone's Trust. The term Global South refers to a group of countries often characterized as developing, less developed, or underprivileged, primarily located in Africa, Latin America, and developing parts of Asia. It is used to distinguish these nations from the Global North, which represents developed, high-income countries. Since the term specifically identifies developing nations and not developed ones, the second statement is incorrect.

Explanation

Cereal yield is a measure of agricultural productivity defined as the amount of grain produced per unit of harvested land area. It is calculated by dividing the total production volume by the total area harvested, typically expressed in kilograms per hectare (kg/ha) or tonnes per hectare. This metric reflects the efficiency of land use and the impact of various factors such as soil fertility, seed quality, irrigation, fertilizers, and climate conditions on crop output. While total production accounts for the cumulative mass of crops grown across an entire region or country, yield specifically isolates the performance of the land itself. Organizations like the Food and Agriculture Organization (FAO) use this measure to track technological progress and food security levels globally.

Explanation

According to the Periodic Labour Force Survey (PLFS) data released by the National Statistical Office (NSO), the unemployment rate (UR) in urban areas for persons aged 15 years and above was 8.4 percent in the July-September quarter of 2019. By the July-September quarter of 2022, this figure had dropped to 7.2 percent. This data illustrates a clear downward trend in the unemployment rate between these two specific periods. The decline is attributed to the steady economic recovery and increased labor force participation following the disruptions caused by the COVID-19 pandemic. As the official statistics show a reduction from 8.4 percent to 7.2 percent, the unemployment rate did not remain static but experienced a significant decline.

Explanation

The Global Multidimensional Poverty Index (MPI) is an international measure of acute multidimensional poverty covering over 100 developing countries. It was launched in 2010 by the Oxford Poverty and Human Development Initiative (OPHI) and the United Nations Development Programme (UNDP) for the UNDP flagship Human Development Report. These two organizations jointly prepare and publish the report annually to monitor progress and capture the simultaneous deprivations that people face in their daily lives, such as poor health, lack of education, and inadequate living standards. The index uses ten indicators across three dimensions—health, education, and standard of living—to identify who is poor and how they are poor.

Explanation

The Brundtland Report, formally titled Our Common Future, was published in 1987 by the World Commission on Environment and Development. It is credited with popularizing the concept of sustainable development by providing its most widely accepted definition as development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Conversely, The Limits to Growth is a separate and distinct study published in 1972 by the Club of Rome, which focused on the consequences of exponential economic and population growth within a finite resource base. Since the Brundtland Report is titled Our Common Future and not The Limits to Growth, the assertion is correct while the reason is false.

Explanation

World Heritage Day is observed every year on April 18 to raise awareness about preserving cultural heritage and diversity. The International Day of Light takes place on May 16, celebrating the role light plays in science, culture, and art, specifically marking the anniversary of the first successful laser operation. World Thyroid Day is recognized on May 25 to emphasize the importance of thyroid health and educate the public on thyroid disorders. World No Tobacco Day is observed on May 31 to highlight the health risks associated with tobacco use and advocate for effective policies to reduce consumption. The chronological sequence based on the calendar months and days is April 18, May 16, May 25, and May 31.

Explanation

Gopi Thotakura (A) matches with 3 because he became the first Indian citizen to fly as a space tourist on Blue Origin's NS-25 suborbital mission in May 2024. Dipa Karmakar (B) matches with 1 as she made history in 2024 by becoming the first Indian gymnast to win a gold medal at the Asian Senior Gymnastics Championships in Tashkent. Aroh Barjatyya (C) is paired with 2 because he is the Indian-born NASA scientist who led the Atmospheric Perturbations around Eclipse Path mission to study the ionospheric impact of the April 2024 solar eclipse. Dev Patel (D) matches with 4 as the British actor who released his feature film directorial debut, the action-thriller Monkey Man, in 2024.

Explanation

According to data released by the Department for Promotion of Industry and Internal Trade (DPIIT) for the fiscal year 2023-24, Singapore was the largest source of Foreign Direct Investment (FDI) into India, contributing approximately $11.77 billion in equity inflows. This continues a multi-year trend where Singapore has overtaken Mauritius as the primary gateway for foreign capital. The shift is largely attributed to the amendment of the India-Mauritius Double Taxation Avoidance Agreement (DTAA), which phased out capital gains tax exemptions and introduced stricter checks like the Principal Purpose Test (PPT) to curb treaty shopping. These regulatory changes reduced the comparative advantage of Mauritius, prompting global investors to route their capital through Singapore, which offers a more robust financial services ecosystem and a sophisticated legal framework. Consequently, the treaty amendments were a direct driver in restructuring FDI flows, making Singapore the dominant source country.

Explanation

R21/Matrix-M is a malaria vaccine developed by the University of Oxford in collaboration with the Serum Institute of India. It is the second vaccine recommended by the World Health Organization for the prevention of malaria in children living in endemic areas. The vaccine uses the Matrix-M adjuvant to enhance the immune system's response to the circumsporozoite protein of the Plasmodium falciparum parasite. The Serum Institute of India is the primary manufacturing partner, providing the large-scale production capacity necessary to deploy the vaccine globally and significantly reduce the burden of malaria-related mortality.

Explanation

Anasuya Sengupta won the Best Performance award in the Un Certain Regard section at the 77th Cannes Film Festival in 2024 for her role in the film The Shameless. Directed by Konstantin Bojanov, the film features Sengupta as Renuka, a woman who escapes a Delhi brothel after a violent confrontation. Her victory was a historic achievement for Indian cinema, as she became the first Indian actor to win a top acting prize in any category at the Cannes Film Festival. The Un Certain Regard jury, led by director Xavier Dolan, honored her for her compelling portrayal of a marginalized character navigating a journey of survival and love.

Explanation

The RudraM-II is an indigenously developed, solid-propelled air-to-surface missile system designed by the Defence Research and Development Organisation (DRDO). It serves as a high-speed anti-radiation and ground-attack weapon intended to neutralize enemy radar, communication sites, and other radio frequency emitting targets from stand-off distances. On May 29, 2024, the missile was successfully flight-tested from a Su-30MKI fighter aircraft of the Indian Air Force. This specific flight test was conducted off the coast of Odisha at the Integrated Test Range in Chandipur, not in Rajasthan. Because the missile is an air-to-surface system and the May 2024 test occurred in Odisha, both statements are incorrect.

Explanation

Gitanas Nauseda secured a second term as the President of Lithuania after winning the runoff election in May 2024. Luong Cuong was elected as the President of Vietnam by the National Assembly in October 2024, succeeding To Lam. Halla Tomasdottir, a prominent businesswoman, won the Icelandic presidential election in June 2024 and took office in August 2024. Jose Raul Mulino was elected as the President of Panama in May 2024 after standing in for the disqualified former president Ricardo Martinelli.

Explanation

The intertrappean beds within the Deccan Trap volcanic sequence are sedimentary deposits formed in inland freshwater lakes and river systems during intervals between successive lava flows. These beds contain a rich record of terrestrial and freshwater biodiversity from the Late Cretaceous period. Typical fossils include freshwater gastropods like Physa prinsepii, land plants, and remains of terrestrial vertebrates such as turtles and dinosaurs. The depositional environment was continental rather than marine, as the volcanic activity occurred while the Indian plate was passing over a mantle plume. Consequently, these beds are characterized by the presence of freshwater life forms rather than sea plants and marine animal fossils.

Explanation

Jet streams are narrow bands of high-speed winds that circulate in the upper troposphere. Although they were extensively documented by pilots during World War II, they are primarily westerly winds, meaning they flow from west to east in both the Northern and Southern Hemispheres. This is due to the combined effect of the atmospheric pressure gradient and the Coriolis force. Consequently, the assertion labeling them as easterly winds is incorrect. The reason provided is accurate because jet streams are defined by their intense speeds, which typically range from 160 km/hour to over 400 km/hour, with peak velocities frequently recorded between 300 and 500 km/hour within the core of the stream during the winter months.

Explanation

The Pyrenees mountain range forms a natural border between Spain and France, stretching approximately 430 kilometers from the Bay of Biscay to the Mediterranean Sea. The Alps are the most extensive mountain system in Europe, and Switzerland is internationally recognized for its central and high-altitude Alpine regions. The Balkan Mountains, or the Stara Planina, are a major mountain range in the eastern part of the Balkan Peninsula, running primarily through the center of Bulgaria. The Apennines consist of a series of mountain ranges that extend about 1,200 kilometers along the entire length of peninsular Italy, serving as the country's geographical backbone. Matching these pairs gives the sequence A-3, B-1, C-4, and D-2.

Explanation

The term terrestrial is derived from the Latin word terra, which means earth or land. In biological and ecological contexts, terrestrial habitants are organisms that live and grow on land. This category encompasses a wide variety of flora and fauna adapted to life in diverse land-based environments such as forests, grasslands, deserts, and mountain regions. These organisms have developed specific physiological and structural adaptations to survive in non-aquatic conditions, including mechanisms for breathing atmospheric oxygen and managing water retention.

Explanation

The joint where the neck joins the head is a pivotal joint. This type of joint allows for the rotation of the head, enabling it to move forward, backward, and side to side. Specifically, the atlanto-axial joint, located between the first cervical vertebra (atlas) and the second cervical vertebra (axis), functions as a pivot. In this arrangement, a bony projection called the dens or odontoid process from the axis fits into a ring formed by the atlas and a ligament, facilitating the turning motion of the skull.

Explanation

Pathogens are biological agents that cause disease or illness to their host. The term is derived from the Greek words pathos, meaning suffering, and genes, meaning producer. This broad category encompasses all types of microorganisms and infectious agents, including certain bacteria, viruses, fungi, and parasites, that have the capacity to bypass the host immune system and cause clinical symptoms or infection. In microbiology and medicine, the classification of an organism as a pathogen is specifically based on its ability to cause harm to a living host through various mechanisms such as toxin production, tissue destruction, or interference with cellular functions.

Explanation

Milk is a colloidal system known as an emulsion, which is a mixture of two or more liquids that are normally immiscible. In milk, the dispersed phase consists of tiny liquid fat globules, while the dispersion medium is water. This specific classification is known as an oil-in-water (O/W) emulsion. The system is stabilized by proteins like casein, which act as emulsifying agents to prevent the fat droplets from coalescing and separating from the aqueous phase.

Explanation

Baking soda is the common name for the chemical compound sodium bicarbonate, which has the chemical formula NaHCO₃. It is an ionic salt consisting of a sodium cation (Na⁺) and a bicarbonate anion (HCO₃⁻). In practical applications, it serves as a leavening agent because it undergoes a chemical reaction that releases carbon dioxide gas (CO₂) when it is heated or combined with an acidic ingredient. This release of gas creates bubbles that expand in doughs and batters, providing the necessary lift for baked products. It is commercially manufactured through the Solvay process, where carbon dioxide and ammonia are passed through a concentrated solution of sodium chloride.

Explanation

CPR is an acronym for Cardiopulmonary Resuscitation, a critical emergency medical procedure used when an individual's heartbeat or breathing has stopped. The term cardio refers to the heart, while pulmonary refers to the lungs, and resuscitation signifies the process of reviving or restoring life. It typically involves a combination of chest compressions and rescue breaths designed to maintain the flow of oxygenated blood to the brain and other vital organs until advanced medical care can be administered. This intervention is a fundamental component of basic life support used in cases of cardiac arrest or near-drowning.

Explanation

In the human circulatory system, veins are generally defined as blood vessels that carry blood toward the heart. While most veins transport deoxygenated blood from the body tissues, the pulmonary vein is the primary exception. It is a critical component of pulmonary circulation, which facilitates gas exchange. Once blood reaches the lungs, it releases carbon dioxide and absorbs oxygen within the alveoli. The pulmonary veins then collect this freshly oxygenated blood and carry it from the lungs to the left atrium of the heart. This oxygen-rich blood is subsequently pumped into the systemic circulation to meet the metabolic demands of the body. This unique functional role makes the pulmonary vein the only vein in the adult human body that carries oxygenated blood.

Explanation

Diabetes mellitus is a chronic metabolic disorder primarily rooted in the dysfunction of the pancreas. The pancreas serves a dual role in the body, but its endocrine function is central to glucose regulation. Within the pancreas, specialized clusters of cells called the Islets of Langerhans contain beta cells, which synthesize and secrete the hormone insulin. Insulin is essential for maintaining blood sugar homeostasis as it facilitates the transport of glucose from the bloodstream into the body's cells to be used for energy. Diabetes occurs when the pancreas fails to produce sufficient insulin, or when the body cannot effectively use the insulin it produces. In Type 1 diabetes, the pancreas produces little to no insulin due to autoimmune destruction of beta cells, while Type 2 diabetes involves a combination of insulin resistance and a progressive decline in the pancreatic secretion of the hormone.

Explanation

The COVID-19 pandemic, which resulted in significant global disruptions and lockdowns, was caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). This novel coronavirus was first identified in Wuhan, China, in late 2019. It belongs to the broad family of coronaviruses that cause illnesses ranging from the common cold to more severe respiratory diseases. The virus spreads primarily through respiratory droplets and aerosols when an infected person coughs, sneezes, or speaks. Due to its high transmissibility and the initial lack of pre-existing immunity in the human population, it triggered a worldwide public health emergency, leading to the prolonged global pause to contain its spread and reduce the burden on healthcare systems.

Explanation

Average speed is defined as the total distance traveled divided by the total time taken. Let the total distance be 2d. The time taken to cover the first half of the distance d at speed v₁ is t₁ = d/v₁, and the time taken to cover the second half of the distance d at speed v₂ is t₂ = d/v₂.

The total time for the journey is T = t₁ + t₂ = d/v₁ + d/v₂. Simplifying this expression by finding a common denominator yields T = d(v₁ + v₂ / v₁v₂). Substituting these values into the average speed formula:

Vₐᵥ₉ = Total Distance / Total Time = 2d / (d(v₁ + v₂ / v₁v₂)) = 2v₁v₂ / (v₁ + v₂)

This mathematical relationship shows that when a journey is divided into two equal distance intervals, the average speed is the harmonic mean of the individual speeds.

Explanation

The Ramganga multipurpose project, located on the Ramganga river, provides irrigation to a total command area of approximately 5.75 lakh hectares. This irrigation network serves the agricultural requirements of several districts in Western Uttar Pradesh, including Bijnor, Moradabad, Rampur, and Bareilly. The matching of 6 lakh hectares is incorrect because the actual irrigation potential established by the project is officially recorded as 5.75 lakh hectares, making the provided figure of 6 lakh hectares an inaccurate representation of the technical specifications.

Explanation

India is situated in the tropical monsoon climate zone, which is characterized by high temperatures and a distinct seasonal distribution of rainfall. These conditions facilitate three main cropping cycles: Kharif, Rabi, and Zaid. The year-round availability of solar radiation and the moisture provided by the seasonal monsoons allow for the growth of a wide variety of crops, ranging from tropical staples like rice and sugarcane to temperate crops like wheat and mustard. This climatic diversity ensures that the country maintains a highly varied agricultural output across different seasons.

Regarding land extent, international data from the Food and Agriculture Organization (FAO) indicates that the United States of America possesses a slightly larger absolute area of arable land, totaling approximately 157.7 million hectares, compared to India's approximately 156 million hectares. Because the USA has a greater total extent of arable land, the claim that India has the maximum geographical area cultivated among the specified group of countries is statistically inaccurate.

Explanation

The Panch Prayag (five sacred confluences) in Uttarakhand are: Devprayag — confluence of Alaknanda and Bhagirathi, where the Ganga officially begins (List-II: 2). Rudraprayag — confluence of Alaknanda and Mandakini from Kedarnath (List-II: 4). Karnaprayag — confluence of Alaknanda and Pindar from Pindari Glacier (List-II: 1). Tehri — confluence of Bhagirathi and Bhilangana, site of the Tehri Dam (List-II: 3). The correct matching is A-2, B-4, C-1, D-3, which corresponds to the code 2 4 1 3 = Option D.

Explanation

Western Europe experiences a Marine West Coast climate, also known as the British type climate, which is characterized by a moderate temperature range and a fairly even distribution of precipitation throughout the year. This year-round rainfall is primarily due to the region's constant exposure to the Atlantic Ocean and the consistent influence of moist maritime air masses. Furthermore, Western Europe is situated within the mid-latitude belt of the prevailing Westerlies, which blow from the southwest across the North Atlantic towards the European landmass. These onshore winds act as a persistent mechanism for transporting moisture and cyclonic depressions from the ocean to the land, ensuring that rainfall occurs across all months without a pronounced dry season.

Explanation

The West to East arrangement of these mountain ranges follows the longitudinal progression across West and South Asia. The Pontic Mountains are located in northern Turkey along the Black Sea coast, roughly between 30° E and 42° E. Moving eastward, the Zagros Mountains run through western and southern Iran, primarily between 45° E and 55° E. Further east, the Hindu Kush range extends through Afghanistan and northern Pakistan, centered around 68° E to 72° E. Finally, the Karakoram range is located at the junction of Pakistan, India, and China, situated between 75° E and 78° E. This sequence accurately reflects the geographical transition from the Anatolian plateau through the Iranian plateau to the high-altitude ranges of the Pamir Knot and the Himalayas.

Explanation

The Mekong River originates in the Tibetan Plateau and flows in a generally south-easterly direction through the Yunnan province of China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. It eventually empties into the South China Sea through the Mekong Delta in southern Vietnam. Because its course traverses the Indochinese Peninsula toward the Pacific Ocean, its primary directional flow is south-east. A south-westerly direction would lead toward the Indian Ocean, which does not characterize the drainage basin of the Mekong.

Explanation

The Kashagan oil field is located in the northern part of the Caspian Sea, within the territorial waters of Kazakhstan. It was discovered in 2000 and is considered one of the largest offshore oil field discoveries in the world in the last several decades. It is developed and operated by the North Caspian Operating Company (NCOC) consortium. Kuwait’s major oil production is instead derived from fields such as Greater Burgan, which is one of the world’s most productive sandstone oil fields, as well as the Raudhatain and Sabriya fields in the north of the country.

Explanation

The Mediterranean climate is characterized by a distinct seasonal rhythm where rainfall is concentrated in the winter months while summers remain dry. This pattern is primarily caused by the seasonal shifting of the planetary wind belts. During the winter, the apparent movement of the sun toward the opposite hemisphere causes the global pressure systems to migrate equatorward. This shift brings the Mediterranean regions, typically located on the western margins of continents between 30 and 45 degrees latitude, under the influence of the moisture-laden Westerlies. These prevailing winds blow from the oceans toward the land, bringing cyclonic and frontal precipitation. The arrival of these moist air masses during the cooler months provides the necessary hydration for the region's unique sclerophyllous vegetation and agricultural cycles.

Explanation

The major anti-Maoist operation carried out in April 2024 took place in the Kanker district of Chhattisgarh, specifically in the forest area near the villages of Binagunda and Hapatola. This operation was conducted as a joint tactical strike by the Border Security Force (BSF) and the District Reserve Guard (DRG) of the Chhattisgarh Police. The DRG is a specialized counter-insurgency unit of the Chhattisgarh state police forces, primarily composed of local tribal youth who possess exceptional knowledge of the regional terrain. The BSF is a central paramilitary force that provides essential operational support in the insurgency-affected Bastar division. The encounter resulted in the neutralization of 29 Maoists, making it one of the most successful engagements against Left Wing Extremism in recent history. Since the District Reserve Guard is a unit unique to the Chhattisgarh Police and the BSF collaborated with them for this specific Kanker-based mission, the involvement of these forces is accurately described.

Explanation

The initial aerodynamic design of spacecraft and launch vehicles requires the evaluation of a large number of airfoils and complex geometric shapes to optimize flight stability and minimize drag. PraVaHa, which stands for Parallel RANS Solver for Aerospace Vehicle Analysis, is a high-end Computational Fluid Dynamics (CFD) software developed by the Vikram Sarabhai Space Centre (VSSC) to facilitate these tasks. It allows engineers to simulate and analyze fluid flow using the Reynolds-Averaged Navier-Stokes (RANS) equations across subsonic, supersonic, and hypersonic regimes. By providing detailed data on pressure and temperature distributions, the software significantly reduces the reliance on costly wind tunnel experiments during the preliminary design phase. Statement 1 is incorrect because the developer is the Vikram Sarabhai Space Centre, not Sagarbhai, whereas statement 2 correctly identifies a primary requirement in the aerospace engineering workflow that this software addresses.

Explanation

India delivered the first batch of BrahMos supersonic cruise missiles to the Philippines in April 2024 as part of a $375 million defense deal signed in 2022. This marked India's first major export of a sophisticated weapon system to a foreign nation. The missiles were transported to the Philippines by the Indian Air Force using C-17 Globemaster transport aircraft. The Reason (R) is incorrect because the standard export version of the BrahMos missile provided to the Philippines has an operational range of approximately 290 kilometers. While extended-range versions (BrahMos-ER) capable of reaching 450 to 500 kilometers have been developed and tested by India, the specific range of 490 kilometers is not the official or standard specification for the missiles transferred under this specific contract.

Explanation

The first Nepal-India International Sanskrit Conclave was held from March 28 to 30, 2024, in Kathmandu, Nepal. This three-day event was organised by the Niti Anusandhan Pratisthan (Policy Research Institute, Nepal) in collaboration with the Central Sanskrit University, New Delhi, and the India Foundation. The conclave brought together scholars and experts from both nations to discuss the promotion and preservation of the Sanskrit language and concluded with a five-point resolution to strengthen bilateral cultural and academic cooperation through Sanskrit.

Explanation

The Lunar Polar Exploration Mission (LUPEX) is a planned robotic lunar mission jointly developed by the Indian Space Research Organisation (ISRO) and the Japan Aerospace Exploration Agency (JAXA). Statement 1 is correct as it is a bilateral collaboration between India and Japan to explore the Moon's South Pole for water ice and other resources, with a launch scheduled in the mid-2020s.

Under the mission framework, the technical responsibilities are clearly divided: JAXA is responsible for providing the H3 launch vehicle and the lunar rover, while ISRO is responsible for developing the lunar lander system. Statement 2 is incorrect because it wrongly attributes the development of the lander to JAXA.

Explanation

The Tamil Nadu School Education Department officially issued the Guidelines for Elimination of Corporal Punishment (GECP) on April 26, 2024, in response to directives from the Madras High Court and the provisions of the Right of Children to Free and Compulsory Education Act, 2009. These guidelines are specifically designed to prioritize and safeguard the physical and mental well-being of students by strictly prohibiting any form of physical discipline, mental harassment, or discrimination within educational institutions. The GECP mandates the formation of Monitoring Committees at the school level to track and address grievances, while encouraging teachers to adopt positive pedagogical practices and psychological interventions instead of punitive measures. By providing a clear framework for accountability, the guidelines seek to foster a fear-free learning environment that supports the healthy emotional and cognitive development of every child.

Explanation

Pradhan Mantri Awas Yojana - Gramin (A) was launched on 20th November 2016 (4) to provide pucca houses with basic amenities to all rural families living in dilapidated houses. Jal Jeevan Mission (B) was launched on 15th August 2019 (3) to ensure functional household tap connections to every rural home by the year 2024. Swachh Bharat Mission (C) was launched on 2nd October 2014 (2) to accelerate efforts toward universal sanitation and to eliminate the practice of open defecation. Pradhan Mantri Ujjwala Yojana (D) was launched on 1st May 2016 (1) to provide clean cooking fuel through LPG connections to women from Below Poverty Line households.

Explanation

The Human Development Index (HDI), published by the United Nations Development Programme (UNDP), is a composite index that measures average achievement in three basic dimensions of human development. The first dimension is a long and healthy life, which is measured by the indicator of life expectancy at birth. The second dimension is access to knowledge, which is measured by two indicators: mean years of schooling for adults aged 25 years and older, and expected years of schooling for children of school entering age. The third dimension is a decent standard of living, measured by Gross National Income (GNI) per capita at purchasing power parity (PPP), which reflects the income level of the population. While environmental sustainability is tracked through other indices like the Planetary pressures-adjusted HDI, it is not a component of the standard HDI calculation.

Explanation

The Swachh Bharat Mission was launched on October 2, 2014, to accelerate efforts to achieve universal sanitation coverage and eliminate open defecation. The Pradhan Mantri Kaushal Vikas Yojana followed on July 15, 2015, aimed at mobilizing youth to take up industry-relevant skill training to secure a better livelihood. The Pradhan Mantri Garib Kalyan Yojana was introduced in December 2016 as part of the Taxation Laws (Second Amendment) Act to provide a voluntary declaration scheme for unaccounted income for the benefit of the poor. Finally, the Pradhan Mantri Mahila Shakti Kendra Scheme was approved in November 2017 to empower rural women through community participation and provide them with a one-stop convergence support for skill development and digital literacy.

Explanation

Thomas Robert Malthus, in his 1798 work An Essay on the Principle of Population, proposed that human populations tend to grow at a geometric rate, represented by the progression 1, 2, 4, 8, 16, 32, because humans have a biological drive to reproduce that leads to doubling over regular intervals. In contrast, he posited that the food supply and agricultural production only increase at an arithmetic rate, represented by the progression 1, 2, 3, 4, 5, 6, because land is a finite resource and additional labor or capital applied to fixed land yields diminishing returns. This fundamental divergence creates a gap between population size and the means of subsistence, which Malthus argued would eventually be corrected by positive checks like famine or preventive checks like moral restraint.

Explanation

The Economic Survey 2022-23 highlights that the Government of India implemented targeted fiscal measures to insulate the domestic economy from the surge in global commodity prices and supply chain disruptions. To control inflation and ease the burden on consumers, the government significantly reduced the Central Excise Duty on petrol and diesel in May 2022. Furthermore, to stabilize input costs for industries, the government lowered or waived import duties on critical raw materials, including pulses, edible oils, and key industrial inputs like coking coal and ferronickel. These tax reductions were instrumental in managing domestic price levels and ensuring the availability of essential goods despite the volatility in international markets caused by geopolitical tensions.

Explanation

Pradhan Mantri Shram Yogi Maandhan (PM-SYM) involves a monthly contribution ranging from ₹ 55 to ₹ 200 based on the entry age of the subscriber to provide a monthly pension to unorganized workers.

Pradhan Mantri Jeevan Jyoti Bima Yojana (PMJJBY) is a life insurance scheme that offers a coverage of ₹ 2 lakh for an annual premium of ₹ 436.

Pradhan Mantri Suraksha Bima Yojana (PMSBY) provides accidental death and disability insurance cover with a highly subsidized annual premium of ₹ 20.

Atal Pension Yojana (APY) is a social security scheme where the pension amount and required contributions are determined by the beneficiary category, specifically the entry age and the chosen slab of fixed monthly pension.

Explanation

Development is a multidimensional concept that encompasses qualitative improvements in the quality of life, such as enhanced health outcomes, better education, and reduced poverty. This definition is fundamentally based on the recognition that growth in per capita income is a purely quantitative metric that fails to account for the distribution of wealth, environmental sustainability, or the general well-being of the population. Because per capita income alone is an insufficient indicator of a nation's progress, the focus of development must shift toward improving living standards and welfare to ensure a holistic assessment of societal advancement. Thus, the limitations of income-based metrics provide the logical necessity for defining development through the lens of human welfare.

Explanation

Sustainable Development Goal 4 (SDG 4) aims to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all by 2030. Target 4.1 of this goal specifically mandates that all girls and boys complete free, equitable, and quality primary and secondary education, which requires making education free and compulsory to eliminate socioeconomic barriers. Additionally, Target 4.a focuses on building and upgrading education facilities that are child, disability, and gender-sensitive to provide safe, non-violent, and effective learning environments. Improving basic school infrastructure and embracing digital transformation are essential to achieving these targets, as they ensure that schools have the necessary physical and technological resources to deliver modern, high-quality education and improve learning outcomes for all students regardless of their location or background.

Explanation

The freedom to acquire, hold, and dispose of property was originally included as a fundamental right under Article 19(1)(f) of the Indian Constitution. However, the 44th Constitutional Amendment Act of 1978 deleted this provision along with Article 31. This amendment shifted the right to property from the category of Fundamental Rights to the status of a legal right. It is now incorporated under Article 300A in Part XII of the Constitution, which states that no person shall be deprived of his property save by authority of law. Consequently, the freedom to own, acquire, and dispose of property is no longer a guaranteed freedom under the cluster of rights provided by Article 19.

Explanation

Assertion (A) is false because the Seventh Constitutional Amendment Act of 1956 amended Article 153 of the Indian Constitution to facilitate the appointment of the same person as Governor for two or more States. Prior to this amendment, the Constitution contemplated a distinct Governor for every state, but the logistical and administrative needs led to this change. Reason (R) is true as it correctly cites the opening mandate of Article 153, which establishes the office by stating that there shall be a Governor for each State. While the proviso added in 1956 allows one individual to hold multiple charges, the fundamental requirement for every state to have a Governor remains intact.

Explanation

Under Article 3 of the Constitution of India, the power to alter the name of any State is vested exclusively in the Parliament. While the President is required to refer the bill for renaming a State to the concerned State Legislature for its views, the Parliament is not bound by those views. The Parliament can proceed with the legislation even if the State Legislature opposes it or fails to provide its opinion within the prescribed time. Therefore, the ultimate authority to change a State's name rests with the Union Parliament through a law passed by a simple majority, and not with the State Legislature.

Explanation

The Consolidated Fund of India (A) is governed by Article 266, which serves as the primary account for all revenues received, including taxes and loan repayments, as well as all loans raised by the government. The Finance Commission (B) is a constitutional body established under Article 280 to recommend the distribution of financial resources between the Union and the States. Financial Emergency (C) provisions are contained in Article 360, which empowers the President to declare an emergency if the financial stability or credit of India is under threat. The Comptroller and Auditor General of India (D) is an independent authority created by Article 148, responsible for auditing the accounts and expenditures of both the Union and the State governments to ensure financial accountability.

Explanation

The Right against Exploitation is a fundamental right enshrined in Articles 23 and 24 of the Indian Constitution. Article 23 prohibits traffic in human beings, begar, and other similar forms of forced labour, ensuring that no person is compelled to work against their will or subjected to human trafficking. Article 24 prohibits the employment of children below the age of 14 years in any factory, mine, or other hazardous occupations to protect their childhood and health from industrial exploitation. These two specific provisions constitute the entirety of the constitutional group categorized as the Right against Exploitation.

Explanation

Input devices are hardware components used to provide data and control signals to an information processing system such as a computer. A mouse is a pointing device that allows users to interact with a graphical user interface by detecting two-dimensional motion. A keyboard is the primary input peripheral used for entering text, numbers, and executing various commands. A scanner is an optical input device that captures images or text from physical documents and converts them into digital data that the computer can process and store. Since each component in this group is designed specifically to feed information into the system, it represents a collection of exclusively input devices.

Explanation

ROM, or Read-Only Memory, is a type of storage medium that permanently stores data on personal computers and other electronic devices. It is classified as non-volatile memory because it does not require a continuous power supply to retain its stored information. This property makes ROM ideal for storing critical system instructions, such as the BIOS (Basic Input/Output System) or firmware, which the computer needs to perform the bootstrap process and initialize hardware components every time it is turned on. Data in ROM is typically written during the manufacturing process and remains intact even when the device is powered off or during a power failure.

Explanation

The relationship between the Fahrenheit scale and the Celsius scale is defined by the linear equation T_F = 9/5 T_C + 32. This formula is derived from the two standard fixed points of water: the freezing point (0°C or 32°F) and the boiling point (100°C or 212°F) at standard atmospheric pressure. Because the interval between these points is 100 units on the Celsius scale and 180 units on the Fahrenheit scale, each degree Celsius is equivalent to 180/100 or 9/5 degrees Fahrenheit. The constant +32 accounts for the offset between the two scales at the freezing point of water. In this context, the notation represents the mathematical dependency where the Fahrenheit value is calculated by scaling the Celsius value by the fraction 9/5 and adding the baseline constant.

Explanation

The nucleus is the most vital organelle during cellular reproduction as it contains the genetic material in the form of DNA and chromosomes. It coordinates the process of cell division by replicating its DNA and then dividing through karyokinesis to ensure that both daughter cells receive an identical or appropriate set of instructions. This process is essential for growth, repair, and the transmission of hereditary traits from one generation of cells to the next, making the nucleus the central director of the reproductive cycle.

Explanation

Acid rain is primarily caused by the chemical reaction of sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and carbon dioxide (CO₂) with water molecules in the atmosphere. These gases are acidic oxides that dissolve in rainwater to form various acids through reactions such as SO₂ + H₂O → H₂SO₃, 4NO₂ + 2H₂O + O₂ → 4HNO₃, and CO₂ + H₂O → H₂CO₃. While CO₂ naturally makes rain slightly acidic, the high concentration of these gases—released through fossil fuel combustion and industrial activities—constitutes atmospheric pollution. This polluted state of the air provides the necessary high-density precursors that significantly lower the pH of precipitation. Since the presence of these specific pollutants in the air is the fundamental condition that enables the formation of acid rain, the Reason correctly explains the Assertion.

Explanation

Statement 1 is correct: At the 7th India-Indonesia Joint Defence Cooperation Committee (JDCC) meeting, Indonesia agreed to enhance collaboration in defence industry, maritime security, and multilateral cooperation. Statement 2 is incorrect: The meeting was held in New Delhi on May 3, 2024, not in Jakarta on May 5, 2024. It was co-chaired by India's Defence Secretary Giridhar Aramane and Indonesia's Secretary General of the Ministry of Defence. Since only Statement 1 is correct.

Explanation

The FWD-200B is a Medium Altitude Long Endurance (MALE) Unmanned Combat Aerial Vehicle (UCAV) developed by the Bengaluru-based private defense firm Flying Wedge Defence and Aerospace Technologies (FWDAT). Unveiled in May 2024, the aircraft has a payload capacity of 100 kg and a maximum takeoff weight (MTOW) of 498 kg. It is designed to carry optical surveillance systems and precision air-strike weapons, such as missile-like munitions, for diverse combat and bombing roles.

Statement 1 is incorrect because the claim of being India's first indigenous bomber UAV is factually contested by earlier state-led projects. The Defence Research and Development Organisation (DRDO) has already developed and tested several indigenous combat-capable (UCAV) platforms, including the Rustom-II (Tapas-BH-201) and the SWIFT (Stealth Wing Flying Testbed). These platforms are classified as indigenous unmanned strike systems that predate the FWD-200B. The FWD-200B is more precisely recognized as the first indigenous bomber UAV to be developed by a private Indian company.

Explanation

Shri Sunil Barthwal, the Commerce Secretary of India, co-chaired the first meeting of the Joint Committee established under the India-Australia Economic Cooperation and Trade Agreement (ECTA) in July 2023. This committee serves as the primary institutional body responsible for overseeing the implementation of the trade pact, reviewing bilateral trade performance, and resolving market access issues. His participation in these high-level meetings ensures government oversight in streamlining trade procedures and facilitates the ongoing negotiations for the more comprehensive CECA (Comprehensive Economic Cooperation Agreement).

DUSTLIK (A): India-Uzbekistan joint exercise, 5th edition, held April 15-28, 2024 at Termez = code 3. SHAKTI (B): India-France joint exercise, 7th edition, held May 13-26, 2024 at Umroi, Meghalaya = code 2. Tiger Triumph (C): Indo-US tri-service exercise harbour phase, held March 18-25, 2024 at Visakhapatnam = code 4. MILAN (D): Biennial multilateral naval exercise, February 19-27, 2024 at Visakhapatnam = code 1. The matching sequence A-3, B-2, C-4, D-1 = 3 2 4 1 = Option B.

Explanation

India has consistently maintained that the Shaksgam Valley is an integral part of the Union Territory of Ladakh. In early 2024, the Indian government lodged a formal protest against China for its attempts to alter the status quo through infrastructural developments, specifically the construction of a road in the valley. This move followed satellite imagery showing new road connectivity from the Chinese G219 highway toward the Shaksgam Valley. The Ministry of External Affairs stated that India has never accepted the 1963 Sino-Pakistan Boundary Agreement, under which Pakistan illegally ceded this territory to China. While the region is part of the territory claimed by India, it is currently under Chinese administration and is distinct from the administrative units of Pakistan-occupied Kashmir (PoK), such as Gilgit-Baltistan or the so-called Azad Kashmir. Therefore, India views any construction in the Trans-Karakoram Tract as a violation of its sovereignty and territorial integrity, leading to the lodging of protests against Chinese activities in the region.

Explanation

The chronological sequence of these government schemes is established by their respective dates of introduction. The Integrated Rural Development Programme (IRDP) was first introduced in 1978 and expanded nationwide in 1980 to provide productive assets and inputs to the rural poor. The Swarnjayanti Gram Swarozgar Yojana (SGSY) was launched on April 1, 1999, as a restructured self-employment program that replaced earlier schemes including the IRDP. The National Rural Employment Guarantee Act (NREGA) was enacted in 2005 and launched in February 2006 to provide a legal guarantee of at least 100 days of wage employment in a financial year to rural households. Finally, the Pradhan Mantri Jan-Dhan Yojana (PMJDY) was launched on August 28, 2014, as a national mission for financial inclusion to ensure that every household has access to at least one basic banking account. This timeline confirms the order as 1, 2, 3, and 4.

Explanation

The Indian economy is fundamentally a mixed economy, a model adopted post-independence where both the private sector and the public sector coexist and contribute to national growth. This framework allows for market forces to operate while the state maintains control over strategic sectors and social welfare. Furthermore, India is traditionally classified as an underdeveloped or developing economy because it exhibits structural characteristics such as low per capita income, significant income inequality, high population growth, and a substantial portion of the workforce engaged in the primary sector compared to high-income developed nations. Statement 3 is inaccurate because Adam Smith is universally regarded as the Father of Economics following his 1776 publication, An Inquiry into the Nature and Causes of the Wealth of Nations, whereas John Maynard Keynes is specifically recognized as the Father of Macroeconomics.

Explanation

A flexible exchange rate system, also known as a floating exchange rate, is defined as a regime where the value of a national currency is determined by the interaction of the market forces of demand and supply for foreign exchange. Under this system, the equilibrium exchange rate is established at the point where the quantity of foreign currency demanded equals the quantity supplied. The demand for foreign currency primarily arises from the need to pay for imports and for making investments abroad, while the supply arises from export receipts and foreign investments coming into the country. These forces are driven by the actions of private individuals, firms, and investors participating in the global economy. Consequently, the central bank does not determine the demand and supply of foreign currency; instead, these are market-driven phenomena. The role of a central bank in a pure flexible exchange rate system is minimal, as it allows the market to reach its own equilibrium without intervention.

Explanation

Financial inclusion aims to provide accessible and affordable financial services to the unbanked and marginalized sections of society. The nationalisation of banks in 1969 and 1980 was a fundamental step in this direction, as it shifted the focus of banking from a profit-driven urban model to a social-priority model, mandating credit flow to agriculture and small-scale industries. Regional Rural Banks were established in 1975 under the RRB Act to combine the local feel of cooperatives with the professional resource mobilization of commercial banks, specifically targeting the credit needs of small farmers and rural artisans. The Village Adoption Scheme, initiated by the Reserve Bank of India and commercial banks, sought to improve the rural credit delivery system by allowing bank branches to focus their developmental efforts on specific villages. Together, these initiatives expanded the geographical and functional reach of the formal financial system across India.

Explanation

The National Food Security Act (NFSA) was enacted in 2013 to provide food and nutritional security by ensuring access to adequate quantities of quality food at affordable prices. Under Section 3(2) of the Act, it legally entitles up to 75 percent of the rural population and 50 percent of the urban population to receive subsidized foodgrains under the Targeted Public Distribution System, covering approximately two-thirds of the country's total population. The Act also places a special emphasis on the nutritional needs of women and children. Pregnant women and lactating mothers are entitled to a nutritious meal free of charge through local anganwadis and maternity benefits of at least Rs. 6,000. Similarly, children in the age group of 6 months to 14 years are entitled to free nutritious meals under the Integrated Child Development Services and Mid-Day Meal schemes. While the Act was indeed enforced on July 5, the year was 2013, not 2010, making the third statement incorrect.

Explanation

The Human Development Index (HDI) is a composite measure focusing on three basic dimensions: a long and healthy life, access to knowledge, and a decent standard of living. In the Indian context, there is a clear positive correlation between a state's HDI score and its performance on the NITI Aayog SDG India Index. This relationship is driven by the fact that the 17 Sustainable Development Goals (SDGs) incorporate and expand upon the core components of human development. Specifically, SDG 3 (Good Health and Well-being) and SDG 4 (Quality Education) directly mirror the health and education pillars of the HDI. Because these foundational human development indicators are weighted significantly within the SDG framework, states that have invested in social infrastructure and human capital naturally achieve higher rankings in both indices. Therefore, the focus of the SDG targets on health and education serves as the underlying reason for the synchronized performance of Indian states across both human development and sustainability metrics.

Explanation

According to the World Bank's Migration and Development Brief, India was the world's largest recipient of remittances in 2022, ranking first. Mexico ranked second, having overtaken China on the back of strong labour-market conditions in the United States. China ranked third, and the Philippines was fourth. Hence Mexico-2, China-3, India-1, Philippines-4, i.e. the code 2 3 1 4.

Explanation

According to the CareEdge Research report 'State of States' (2023), which ranks states by cumulative expenditure on infrastructure over 2019-23, the rankings are as follows:

Uttar Pradesh - First: about Rs 5.31 lakh crore, driven by massive investment in mega-projects such as expressways and dedicated freight corridors. Maharashtra - Second: about Rs 4.39 lakh crore. Tamil Nadu - Third: about Rs 2.84 lakh crore. Karnataka - Fourth: about Rs 2.76 lakh crore.

Hence Maharashtra-2, Uttar Pradesh-1, Tamil Nadu-3, Karnataka-4, i.e. the code 2 1 3 4.

Explanation

Article 352 of the Indian Constitution empowers the President to issue a Proclamation of Emergency if he is satisfied that a grave situation exists whereby the security of India or any part of its territory is threatened by war, external aggression, or armed rebellion. This makes Assertion (A) correct as it accurately identifies the article governing National Emergency. Reason (R) is considered false because, in a constitutional context, an emergency cannot be declared arbitrarily or at any time without the fulfillment of specific conditions. Following the 44th Amendment Act of 1978, the President can only proclaim an emergency after receiving a written recommendation from the Union Cabinet. Furthermore, the proclamation must be based on the specific grounds mentioned in the text of Article 352 and is subject to judicial review and parliamentary approval, meaning it is not an unconditional power that can be exercised at any time without cause.

Explanation

e-Governance leverages Information and Communication Technology to streamline administrative processes, leading to significant cost reductions for the government by automating routine tasks, minimizing paper usage, and decreasing the need for physical infrastructure and manual labor. Furthermore, it enhances democratic participation by providing digital platforms that facilitate direct communication between the state and its citizens. These ICT tools allow for real-time feedback, public consultations, and active citizen engagement in policy formulation and grievance redressal, thereby substantially increasing the volume and quality of citizen input into governmental functions. Through the integration of technology, the government can reach a wider audience more efficiently, ensuring that public services are more responsive to the needs and suggestions of the population.

Explanation

The Union Public Service Commission (UPSC) derives its mandate and operational scope from a combination of constitutional, legislative, and administrative sources. Articles 315 to 323 of the Constitution establish the Commission and enumerate its primary functions, such as conducting examinations for appointments to the services of the Union. Article 321 further empowers the Parliament to expand these functions through legislation, allowing the UPSC to handle recruitment for local authorities or other public bodies. Executive rules and orders, particularly those issued by the President under the provisos of Article 320, define specific areas of consultation and procedural requirements. Additionally, long-standing administrative conventions govern the relationship between the UPSC and the executive, such as the practice of the government almost invariably accepting the Commission's advice on disciplinary matters and recruitment rules, which solidifies its functional role in the Indian polity.

Explanation

The correct constitutional provisions are: Election Commission (Art. 324), National Commission for Scheduled Castes (Art. 338), Finance Commission (Art. 280), and National Commission for Backward Classes (Art. 338B, inserted by the 102nd Constitutional Amendment Act, 2018). Among the options, only Option D pairing NCBC with Art. 338B is correctly matched, as the NCBC was given constitutional status only through this 2018 amendment.

Explanation

The chronological sequence of these landmark Supreme Court cases follows the timeline of Indian constitutional evolution. Shankari Prasad vs. Union of India was decided in 1951, validating the First Amendment and the power of Parliament to amend Fundamental Rights. Sajjan Singh vs. State of Rajasthan was decided in 1965, where the court maintained that constitutional amendments were not subject to Fundamental Rights restrictions under Article 13. Golaknath vs. State of Punjab followed in 1967, reversing previous rulings to state that Parliament had no power to abridge Fundamental Rights. Finally, Kesavananda Bharati vs. State of Kerala in 1973 established the Basic Structure doctrine, allowing amendments provided they do not alter the core features of the Constitution.

Explanation

The 42nd Amendment of 1976 introduced significant changes to the Constitution, such as the addition of the terms Socialist, Secular, and Integrity to the Preamble. The 52nd Amendment, implemented in 1985, established the Tenth Schedule to regulate political defections in legislatures. The 86th Amendment of 2002 inserted Article 21A, making education a fundamental right for children. The 96th Amendment in 2011 officially changed the spelling of the language listed in the Eighth Schedule from Oriya to Odia. These historical implementations match the sequence of 3, 1, 4, and 2.

Explanation

(A) Cooperative Federalism - Granville Austin: He characterized the Indian federal structure as cooperative, highlighting the partnership and mutual dependence between the Union and the States. (B) Bargaining Federalism - Morris-Jones: He used this term to describe the political pattern of negotiation and bargaining that occurs between the Centre and the States in the Indian system. (C) Quasi Federalism - K.C. Wheare: He defined the Indian Constitution as quasi-federal, meaning it is essentially a unitary state with subsidiary federal features rather than a traditional federation. (D) Federalism with Centralising Tendency - Ivor Jennings: He observed that the Indian system is a federation with a strong centralising tendency, ensuring the dominance of the Union government over the states.

Explanation

The Balwant Rai Mehta Committee, which submitted its report in 1957, recommended the establishment of a three-tier Panchayati Raj system to implement democratic decentralization. The three specific levels proposed were the Gram Panchayat at the village level, the Panchayat Samiti at the block level, and the Zilla Parishad at the district level. Nyaya Panchayats, which are judicial bodies meant for handling petty civil and criminal cases at the local level, were not included as one of the fundamental tiers in this administrative hierarchy. Instead, the concept of Nyaya Panchayats was more prominently advocated by later bodies, such as the Ashok Mehta Committee in 1978, as separate entities for the administration of justice.

Explanation

Under Section 4(1) of the Lokpal and Lokayuktas Act, 2013, the Lokpal is appointed by the President based on the recommendations of a Selection Committee. This committee is chaired by the Prime Minister and includes the Speaker of the Lok Sabha, the Leader of Opposition in the Lok Sabha, and the Chief Justice of India or a Judge of the Supreme Court nominated by the Chief Justice. Additionally, the committee includes one eminent jurist nominated by the President on the recommendation of the other members. Statement 1 is correct as it identifies the judicial representation. Statement 3 is correct as the Speaker of the Lok Sabha is a statutory member. Statement 4 is correct as the Leader of Opposition in the Lok Sabha is mandated to be part of the selection process to ensure bipartisan representation. The Chairman of the Rajya Sabha is not a member of this specific Selection Committee.

Explanation

The Congress Socialist Party (CSP) was not formed in January 1934; instead, the first All-India Congress Socialist Conference was held in Patna in May 1934, and the party was formally inaugurated at a conference in Bombay in October 1934. Key founding figures included Jayaprakash Narayan, Acharya Narendra Dev, and Minoo Masani.

Although Jawaharlal Nehru was a staunch advocate of socialist principles and frequently expressed his sympathy for the movement in his writings and presidential addresses, he never formally joined the Congress Socialist Party. Nehru preferred to remain a leader of the Indian National Congress as a whole to maintain national unity and influence the entire organization toward a socialist direction from within, rather than limiting himself to a specific faction. Subhash Chandra Bose similarly supported socialist goals but also refrained from formal membership in the CSP.

Explanation

Sheikh Mubarak Nagori, the father of Abu Fazl and Faizi, died in September 1593. He was a distinguished scholar and a leading figure in the religious discussions at the Ibadat Khana. His eldest son, the poet laureate Faizi, passed away in October 1595. Following these events, Abu Fazl, the celebrated author of the Akbarnama and a close confidant of Emperor Akbar, was murdered in August 1602. The assassination was carried out by Vir Singh Deo of Orchha near Narwar at the instigation of Prince Salim. Finally, Prince Daniyal, the youngest son of Emperor Akbar, died in March 1604 while stationed in the Deccan, primarily due to health complications caused by excessive alcohol consumption.

Explanation

The resignation of Congress ministers took place in October and November 1939 as a protest against the British government's unilateral decision to involve India in World War II without the consent of Indian political leadership. This was followed by the Ramgarh Congress Convention in March 1940, presided over by Maulana Abul Kalam Azad, where the Congress reiterated its demand for a constituent assembly and complete independence. Subsequently, Viceroy Lord Linlithgow issued the August Offer on August 8, 1940, in an attempt to secure Indian support for the war effort by promising dominion status and the expansion of the Viceroy's Executive Council. Finally, the Cripps Mission, led by Sir Stafford Cripps, arrived in India in March 1942 to negotiate constitutional reforms and Indian military cooperation during the ongoing conflict.

Explanation

Hindu Polity (A) was authored by K.P. Jayaswal (3) in 1924, a nationalist work that sought to prove the existence of republican and constitutional traditions in ancient India. The Wonder That Was India (B) was written by the British indologist A.L. Basham (2) in 1954 as a comprehensive survey of Indian culture and history before the Muslim conquests. An Introduction to the Study of Indian History (C) is a seminal 1956 work by D.D. Kosambi (1) that introduced the Marxist approach to Indian history, focusing on the development of means of production and social relations. The Early History of India (D) was written by Vincent Arthur Smith (4) in 1904, representing the first systematic effort to construct a chronological political history of ancient India from a colonial perspective.

Explanation

Early nationalists, or the Moderates, were deeply influenced by Western liberal thought and perceived British rule as a historical necessity to propel India toward modernization. They viewed the British connection as an act of providence that introduced modern education, infrastructure, and democratic ideals. Their political strategy was based on the belief that the British people and Parliament were inherently just but were unaware of the ground realities in India. Consequently, they directed their criticism toward the Un-British character of the Indian administration, arguing that the colonial government was failing to uphold the very standards of justice and liberty practiced in England. This distinction allowed them to remain loyal to the British Crown while advocating for reforms that would align Indian governance with British liberal principles, thereby validating their view of the British connection as a catalyst for modernization.

Explanation

William A.J. Archbold was a British academic who held several significant administrative positions in colonial India, but he never served as the Principal of Lahore College (Government College, Lahore). His career in India is primarily defined by his tenures at three other institutions. He succeeded Theodore Morison as the Principal of the Muhammadan Anglo-Oriental (MAO) College in Aligarh in 1905, where he played a key role in the politics surrounding the Simla Deputation. Following his time in Aligarh, he served as the Principal of Government College, Dacca, and later as the Principal of Muir Central College in Allahabad. There is no historical record of him holding the top administrative post in Lahore.

Explanation

The chronological sequence of these events is determined by their historical dates in the early 19th century. Nana Fadnavis, the influential Maratha statesman and minister, passed away on March 13, 1800, an event that led to increased instability within the Maratha Empire. Lord Wellesley, who served as Governor-General from 1798 and expanded British territory through the Subsidiary Alliance, was recalled to England in 1805 due to the mounting financial costs of his military campaigns. The Vellore Mutiny, a violent uprising by Indian sepoys against the British East India Company triggered by changes in military dress regulations, occurred in July 1806. The Anglo-Nepalese War, also known as the Gorkha War, took place later from 1814 to 1816 during the governor-generalship of Lord Hastings. The sequence of years is 1800, 1805, 1806, and 1814.

Explanation

Bakshi Jagabandhu Bidyadhar Mahapatra was the hereditary military chief of the Raja of Khurda who led the Paika Rebellion of 1817 in Odisha against the British East India Company's unfair land revenue policies and the resumption of rent-free lands.

Mufti Muhammad Aiwaz was a revered local leader in Bareilly who spearheaded the 1816 uprising against the British imposition of a house tax for maintaining the municipal police, which the local population found oppressive.

Edachena Kungan served as a chief lieutenant and military commander for Kerala Varma Pazhassi Raja during the resistance in Malabar against British encroachment and revenue demands in the late 18th and early 19th centuries.

Radharam Dutta was a significant figure in the resistance against British administrative and fiscal changes in Sylhet during the late 18th century, leading local forces against the Company's authority to protect traditional rights.

Explanation

National Maritime Day is observed in India on April 5 to commemorate the 1919 maiden voyage of the SS Loyalty, the first ship of the Scindia Steam Navigation Company Ltd. World Health Day is celebrated annually on April 7, marking the anniversary of the founding of the World Health Organization in 1948. World Athletics Day is observed on May 7, an initiative started by the International Amateur Athletic Federation to encourage sports participation and fitness among youth.

Explanation

The Aryabhatta Award 2024 was conferred upon Dr. Subba Rao Pavuluri, the Chairman and Managing Director of Ananth Technologies, by the Astronautical Society of India in recognition of his lifetime contribution to astronautics and space technology in India. The inaugural World Literary Prize 2024 was awarded to the acclaimed Canadian author Margaret Atwood for her profound impact on global literature through her diverse body of work. The Lata Deenanath Mangeshkar Award 2024 was presented to the legendary actor Amitabh Bachchan for his extraordinary service to the nation and his monumental achievements in the field of cinema. Alok Shukla, an environmental activist and convener of the Chhattisgarh Bachao Andolan, was honored with the Goldman Environmental Prize 2024 for leading a successful community movement to protect the Hasdeo Arand forest from coal mining, securing a victory for indigenous land rights and biodiversity.

Explanation

Vitamin A is associated with Blindness because it is required for the production of rhodopsin and the maintenance of healthy corneal tissues. Vitamin B, specifically B1 or thiamine, is linked to Beriberi which affects the peripheral nerves and cardiovascular system. Vitamin C deficiency leads to Scurvy because the vitamin is a mandatory cofactor for collagen synthesis and wound healing. Vitamin D deficiency results in Rickets in children due to impaired mineralization of bone tissue and insufficient calcium absorption from the gut. These pairings correspond to the sequence 2, 1, 4, 3.

Explanation

Article 350-B of the Constitution of India provides for the appointment of a single Special Officer for Linguistic Minorities by the President of India. The officer is mandated to investigate all matters relating to the safeguards provided for linguistic minorities across the country and report to the President; there is no constitutional provision for a separate Special Officer for every State. This article was inserted into the Constitution by the 7th Constitutional Amendment Act, 1956, following the recommendations of the States Reorganisation Commission (1953-55), whereas the 9th Constitutional Amendment Act, 1960, related to the transfer of certain territories to Pakistan.

Explanation

The Seventh Schedule of the Constitution of India contains the Concurrent List (List III), which specifies subjects where both the Parliament and State Legislatures possess legislative jurisdiction. Adulteration of foodstuffs and other goods is explicitly listed under Entry 18 of the Concurrent List. Succession, along with related personal law matters such as wills, intestacy, joint family, and partition, is covered under Entry 5 of the Concurrent List. While Entry 33 of the Concurrent List does involve trade and commerce, it is restricted to specific commodities like products of controlled industries, foodstuffs, and raw materials. General trade and commerce are primarily categorized under the State List for intra-state matters (Entry 26) and the Union List for inter-state matters (Entry 42). Therefore, the entries for the adulteration of goods and succession are the components that reside within the Concurrent List.

Explanation

Justice M. Fathima Beevi was appointed as the first female judge of the Supreme Court of India in 1989. This historic appointment also made her the first Muslim woman to reach the higher judiciary in India. While she held the post of Governor from 1997 to 2001, she served the state of Tamil Nadu rather than Kerala.

Explanation

The National Intellectual Property Rights (IPR) Policy, 2016, serves as a comprehensive vision document to stimulate innovation and creativity across the country. Statement 1 is correct because the policy explicitly reaffirms India's commitment to the Doha Development Agenda and the WTO Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS). It specifically emphasizes utilizing the flexibilities provided in the TRIPS agreement to protect public health and ensure access to affordable medicines. Statement 2 is correct because the Department of Industrial Policy and Promotion (DIPP), which has since been renamed the Department for Promotion of Industry and Internal Trade (DPIIT), was designated as the nodal agency for all IPR-related matters in India. To create a streamlined and centralized institutional mechanism, the policy transferred the administration of the Copyright Act and the Semiconductor Integrated Circuits Layout-Design Act to the DIPP, placing them under the Ministry of Commerce and Industry.

Explanation

The 73rd and 74th Constitutional Amendment Acts, passed in 1992 and coming into effect in 1993, provided constitutional status to local self-government institutions in India. The 73rd Amendment Act introduced Part IX to the Constitution and the Eleventh Schedule, which details 29 functional items for Panchayati Raj Institutions in rural areas. The 74th Amendment Act introduced Part IXA and the Twelfth Schedule, outlining 18 functional items for Municipalities in urban areas. These amendments established a uniform three-tier system of local governance, mandated regular elections every five years, provided for the reservation of seats for women and marginalized communities, and created State Finance Commissions to ensure financial viability for these local bodies.

Explanation

Lallanji Gopal authored The Economic Life of Northern India, which is a significant work analyzing the socio-economic transformations in North India from approximately 700 to 1200 AD. Mohammad Habib and K.A. Nizami are the principal historians behind the detailed volume on the Delhi Sultanate often titled A Concise History of India: The Delhi Sultanate in various educational contexts. K.S. Lal is recognized for his scholarly monograph History of the Khaljis, which provides an in-depth political and administrative account of the Khalji dynasty between 1290 and 1320. Dashrath Sharma is the author of Early Chauhan Dynasties, a comprehensive study focusing on the political history and institutions of the Chauhan rulers up to the early 14th century.

Explanation

Kunwar Singh was the elderly zamindar of Jagdishpur in the Shahabad district of Bihar who became a legendary figure of the 1857 Indian Rebellion. Despite being nearly eighty years old, he provided strong leadership and organized armed resistance against British forces, successfully occupying Arrah and engaging in strategic warfare across Bihar and parts of Uttar Pradesh. In contrast, the British policy under Lord Dalhousie was defined by the Doctrine of Lapse, which prohibited adopted heirs from inheriting the throne of a dependent princely state in the absence of a biological male heir. Consequently, Dalhousie refused to recognize Damodar Rao, the adopted son of Maharaja Gangadhar Rao and Rani Lakshmibai, as the legitimate successor, leading to the annexation of Jhansi in 1854.

Explanation

Fa-hien (4) was a Chinese Buddhist monk who visited India during the reign of Chandragupta II of the Gupta Dynasty between 399 and 414 CE. He is the earliest traveler among the given options, primarily focusing on collecting Buddhist scriptures.

I-tsing (3) was another Chinese Buddhist traveler who visited India in the late 7th century, between 671 and 695 CE. He spent a significant amount of time studying at the Nalanda monastery and provided detailed accounts of the Buddhist practices of that era.

Itmang (1) refers to a variation or misspelling of travelers from the mid-to-late first millennium; in the context of standard historical chronology provided in competitive examinations, this figure belongs to the era after the initial wave of Chinese pilgrims but before the arrival of Persian or Arabic scholars.

Al-Biruni (2) was a polymath and scholar from Khwarezm who accompanied Mahmud of Ghazni to India in the early 11th century (c. 1017–1030 CE). His work, Kitab-ul-Hind, provides a detailed account of Indian religion, philosophy, and geography. He is the latest traveler in this list.

The chronological sequence is thus Fa-hien (4th-5th Century), I-tsing (7th Century), Itmang, and Al-Biruni (11th Century), which corresponds to the order 4, 3, 1, 2.

Explanation

Ghiyas-ud-din Balban implemented a policy of centralization to restore the prestige of the sultanate and consolidate his authority after the period of instability following Iltutmish's death. He introduced the Persian court etiquette of Sijda and Paibos to emphasize the divine right of kingship (Niyabat-i-Khudai) and crushed the power of the Chahalgani (the Group of Forty) to ensure absolute control over the administration.

Simultaneously, Balban recognized the grave threat posed by the Mongols and focused on securing the north-western frontier. He repaired old forts, built new ones in strategic locations like Sunam and Samana, and organized a specialized military force to guard the borders. While both statements are historically accurate, the primary motivation for Balban's domestic centralization was the internal political necessity of asserting royal supremacy over the Turkish nobility rather than the external military necessity of defending against Mongol invasions. Therefore, the reason does not serve as a direct explanation for the assertion.
