UPPSC Prelims 2017 Question Paper with Answers & Explanations

Explanation

Carbon dioxide is a minor but crucial component of the Earth's atmosphere, playing a vital role in the greenhouse effect and the carbon cycle. For a long period during the Holocene epoch, the concentration of carbon dioxide remained relatively stable at approximately 280 parts per million (ppm). In environmental science and geography, this stable state is traditionally rounded to 0.03 percent by volume (0.03% = 300 ppm). This concentration is considered the optimum level for maintaining the natural thermal balance of the planet, as it provides enough heat retention to prevent the Earth from freezing while avoiding the rapid global warming associated with higher concentrations. Standard atmospheric models used in academic curricula typically cite this 0.03 percent figure as the baseline for a balanced atmosphere.

Explanation

Humidity represents the concentration of water vapor present in the air. Since rain is the product of the condensation of atmospheric water vapor, the total amount of precipitation that can occur is directly determined by the moisture content available in the atmosphere. When air is cooled below its dew point, the water vapor condenses into droplets; the greater the absolute humidity, the more water is available to fall as rain. Consequently, high humidity levels are a prerequisite for significant rainfall amounts, as seen in tropical regions compared to arid ones.

Explanation

World No Tobacco Day is observed annually on 31st May. This global initiative was established by the Member States of the World Health Organization in 1987 to draw global attention to the tobacco epidemic and the preventable death and disease it causes. The date of 5th May mentioned in the option is incorrect for this observance, as the international community recognizes the final day of May for anti-tobacco awareness and advocacy.

Explanation

The greenhouse effect leads to a rise in global temperatures, which triggers positive feedback mechanisms that increase the concentration of carbon dioxide (CO₂). As the atmosphere and oceans warm, the solubility of CO₂ in seawater decreases, causing the oceans to release stored carbon dioxide back into the atmosphere. Furthermore, higher temperatures accelerate the rate of organic matter decomposition in soils and the thawing of permafrost, both of which release significant quantities of CO₂, thereby increasing its total atmospheric concentration over time.

Explanation

The United Nations General Assembly adopted resolution 67/215 in December 2012, which officially designated the period 2014–2024 as the Decade of Sustainable Energy for All. This global initiative was established to promote the importance of energy for sustainable development and to mobilize action toward achieving universal energy access, improving energy efficiency, and increasing the use of renewable energy sources worldwide. It serves as a framework to support the Sustainable Development Goal 7, aiming to ensure that everyone has access to affordable, reliable, sustainable, and modern energy by the year 2030. The initiative emphasizes the critical role that sustainable energy plays in poverty eradication, economic growth, and environmental protection.

Explanation

The Bhopal Gas Tragedy, which occurred on the night of December 2-3, 1984, was caused by the accidental release of Methyl Isocyanate (CH₃NCO). This highly toxic and volatile chemical compound was being used at the Union Carbide India Limited pesticide plant to manufacture carbamate-based pesticides. The disaster was triggered when water entered a storage tank containing approximately 42 tonnes of liquid Methyl Isocyanate, causing a runaway exothermic reaction that significantly increased the temperature and pressure inside the tank. This forced the emergency venting of the gas into the atmosphere, leading to one of the world's worst industrial disasters.

Explanation

Tropical rain forests possess the highest plant biomass of any terrestrial ecosystem due to the combination of high year-round temperatures and abundant precipitation. These equatorial regions provide optimal conditions for photosynthesis and continuous growth without the constraints of a dormant winter or a prolonged dry season. This leads to exceptionally high Net Primary Productivity (NPP), allowing for the development of dense, multi-layered canopies and massive tree structures. The resulting standing crop of organic matter per unit area in a tropical rain forest is significantly greater than that found in seasonal or arid biomes.

Explanation

The Forest Conservation Act was enacted by the Parliament of India and came into force on October 25, 1980. The primary objective of this legislation is to check the rapid deforestation and regulate the diversion of forest lands for non-forest purposes, such as industrial projects, mining, or infrastructure development. Under this act, any such diversion requires the prior approval of the Central Government. The act was a significant step in environmental governance, aligning with the constitutional mandate under Article 48A and Article 51A(g), which direct the state and citizens to protect and improve the natural environment, including forests and wildlife.

Explanation

Tropical forests are represented by Silent Valley in Kerala, which is a prime example of a tropical moist evergreen forest ecosystem located in the Western Ghats. Conifer forests are characteristic of the temperate and sub-alpine regions of Himachal Pradesh, where species like Deodar, Pine, and Spruce thrive in the Himalayan altitude. Mangroves are found in the Sunderbans of West Bengal, which comprises the largest tidal halophytic forest system globally in the Ganga-Brahmaputra delta. Deciduous forests are prevalent in parts of Rajasthan, particularly in the Aravalli range and eastern regions, where tropical dry deciduous and thorn forests are the dominant vegetation types.

Explanation

The destruction of natural habitats and vegetation is widely recognized by ecologists and conservation organizations as the primary driver of biodiversity loss. Habitats provide the specific environmental conditions, food sources, and breeding grounds that species require to survive and reproduce. When these natural areas are cleared or fragmented for infrastructure, urbanization, or resource extraction, the resident species lose their ecological niche. This loss of living space leads to immediate population declines, reduced genetic diversity, and eventual extinction. Scientific assessments, such as those by the International Union for Conservation of Nature (IUCN), consistently rank habitat loss as the most direct and pervasive threat to terrestrial and aquatic species worldwide.

Explanation

Rhizobium is a genus of nitrogen-fixing bacteria that forms a symbiotic relationship with the roots of leguminous plants. Specifically, the species Rhizobium leguminosarum (biovar viciae) is the biological partner that infects and forms nodules in the roots of the pea plant (Pisum sativum). Within these nodules, the bacteria utilize the enzyme nitrogenase to convert atmospheric nitrogen (N₂) into ammonia (NH₃), which the host plant can readily assimilate for growth. This relationship is highly host-specific; while other biofertilizers may be free-living or broader in application, the pairing of Rhizobium leguminosarum with the pea plant is a definitive example of mutualistic symbiosis, where the plant provides carbohydrates and a protected environment in exchange for fixed nitrogen.

Explanation

The 42nd Amendment Act, 1976, curtailed the power of judicial review and also added the words "socialist", "secular", and "integrity" to the Preamble. The 44th Amendment Act, 1978, abolished the Right to Property as a Fundamental Right by removing Article 31 and making it a legal right under Article 300A. The 61st Amendment Act, 1988, lowered the voting age from 21 to 18 years by amending Article 326. The sequence for (A) Curtailment of judicial review = 2 (42nd), (B) Abolition of property right = 4 (44th), (C) Lowering voting age = 1 (61st) gives code 2, 4, 1 = Option B.

Explanation

Article 1 of the Indian Constitution describes India as a Union of States rather than a Federation of States. This concept was derived from the British North America Act of 1867, which created the Dominion of Canada. During the Constituent Assembly debates, Dr. B.R. Ambedkar explained that the term Union was preferred to emphasize two critical points: first, that the Indian federation was not the result of a voluntary agreement or contract among sovereign units, and second, that the constituent states have no right to secede from the federation. By adopting this terminology from the Canadian model, the framers of the Constitution established a federal system with a strong central authority and an indissoluble nature, ensuring the territorial integrity and unity of the nation.

Explanation

According to Article 100(3) of the Constitution of India, the quorum required to constitute a meeting of either House of Parliament is one-tenth of the total number of members of that House. This requirement includes the presiding officer, such as the Speaker in the Lok Sabha or the Chairman in the Rajya Sabha. If at any time during a meeting there is no quorum, Article 100(4) makes it the duty of the Speaker or the person acting as such to either adjourn the House or suspend the meeting until the quorum is present. For the Lok Sabha, which has a total strength of 545 members, this means at least 55 members must be present for the House to conduct its proceedings.

Explanation

The Sarkaria Commission was set up in June 1983 by the Government of India to examine the relationship and balance of power between state and central governments and suggest changes within the framework of the Constitution of India. The commission was headed by Justice Ranjit Singh Sarkaria, a retired judge of the Supreme Court of India. It consisted of two other members, namely Shri B. Sivaraman and Dr. S.R. Sen. Dr. Samar Ranjan Sen was a prominent economist who had previously served as the executive director of the World Bank. The commission submitted its final report in 1988, providing 247 recommendations that aimed to strengthen the federal structure and improve coordination between the Union and the States.

Explanation

The allocation of seats in the Rajya Sabha (Council of States) for each state is specified in the Fourth Schedule of the Constitution of India. Gujarat is allocated 11 seats, which corresponds to item 2 in List-II. Karnataka is allocated 12 seats, matching item 3. Kerala is allocated 9 seats, which corresponds to item 1. Odisha is allocated 10 seats, represented by item 4. This distribution is based on the population of each state to ensure proportional representation in the upper house of the Indian Parliament.

Explanation

The Model Code of Conduct (MCC) is a set of guidelines issued by the Election Commission of India to regulate the behavior of political parties and candidates during elections to ensure a level playing field. These guidelines come into operational effect immediately upon the announcement of the election schedule by the Election Commission and remain in force until the completion of the electoral process. The MCC is not a statutory document and was not enacted by the Parliament of India. It originated from a voluntary agreement among political parties to follow certain ethical standards and evolved through consensus over time. While the code itself is not legally enforceable in a court of law, the Election Commission exercises its constitutional powers under Article 324 to ensure compliance, and specific violations can be penalized under existing laws such as the Representation of the People Act, 1951, and the Indian Penal Code.

Explanation

The scope of judicial review in India is considered limited compared to the United States because the Indian Constitution primarily adheres to the principle of procedure established by law as articulated in Article 21. This means the judiciary examines whether a law has been enacted by a competent legislature following the correct procedure, rather than applying the broader American doctrine of due process of law, which allows for a more extensive scrutiny of the reasonableness and fairness of a law. Statement (R) is also factually correct because the Indian Constitution is often described as a patchwork of various global constitutional features, having adapted elements like the parliamentary system from the United Kingdom and fundamental rights from the USA. However, the general fact that the Constitution contains borrowed items does not serve as a logical explanation for the specific legal constraints and functional boundaries of judicial review in the Indian legal system. Both statements are true independently, but there is no causal link between the constitution's diverse origins and the specific scope of judicial power.

Explanation

The Third Schedule of the Indian Constitution prescribes the forms of oaths or affirmations for several key constitutional functionaries. This includes the form of oath for a Union Minister (i), who is required to subscribe to an oath of office and an oath of secrecy. The schedule also covers the form of oath for the Chief Justice of the Supreme Court (ii), as well as the other Judges of the Supreme Court, the Comptroller and Auditor-General of India, and the Judges of the High Courts. Additionally, it contains the oath for a Member of Parliament (iv) and candidates contesting elections to either House of Parliament. The oath for the President of India (iii) is not included in the Third Schedule because it is specifically provided for in the main text of the Constitution under Article 60. Similarly, the oaths for the Vice-President and State Governors are detailed in Article 69 and Article 159 respectively, rather than in the Third Schedule.

Explanation

According to Article 94 of the Constitution, the Speaker of the outgoing Lok Sabha vacates their office immediately before the first meeting of the newly elected House. To facilitate the initial proceedings, the President appoints a Speaker Protem under Article 95(1) to perform the duties of the Speaker. By established parliamentary convention, the President chooses one of the senior-most members of the newly elected Lok Sabha for this temporary role. The primary responsibilities of the Speaker Protem include presiding over the first sitting of the Lok Sabha, administering the oath or affirmation to the newly elected members as per Article 99, and enabling the House to elect a permanent Speaker. The office of the Speaker Protem is temporary and ceases to exist once the new Speaker is elected.

Explanation

The term Bullock-Capitalists was coined by political scientists Lloyd and Susanne Rudolph to describe a significant class of self-employed, independent agricultural producers in India. These farmers typically own between 2.5 and 15 acres of land, which provides them with enough resources to be self-sufficient and produce a surplus for the market. They are called capitalists because they own their means of production, such as land and bullocks, yet they are not considered rich or part of the large landed elite because they rely primarily on family labor rather than large-scale hired help. This middle category of peasantry became a powerful economic and political interest group in rural India following land reforms and the Green Revolution.

Explanation

The Rajya Sabha, or the Council of States, was formally constituted for the first time on April 3, 1952. This followed the conclusion of the first general elections in independent India, which were held between October 1951 and February 1952. Although the Constitution of India came into force in 1950, the provisional Parliament served as the sole legislative body until the bicameral legislature was established under the new constitutional provisions. The first sitting of the Rajya Sabha took place on May 13, 1952, with Dr. S. Radhakrishnan serving as the first Chairman. Under Article 80 of the Constitution, the House was designed as a permanent body representing the interests of the states and union territories.

Explanation

Article 263 of the Constitution of India empowers the President to establish an Inter-State Council if at any time it appears that the public interest would be served by its creation. Under this article, the President is authorized to define the nature of the duties to be performed by the Council, as well its organization and procedure. This constitutional provision ensures a mechanism for coordination between the Union and the States, as well as among the States themselves. The Inter-State Council was first established by a Presidential Order in 1990, following the recommendations of the Sarkaria Commission.

Explanation

India is established as a democratic republic by its Preamble, where the source of authority is the people who exercise their power through universal adult franchise and representative institutions. Separately, India possesses a comprehensive written constitution, which serves as the supreme law of the land and defines the structure and functions of government institutions. While both statements are factually correct, the existence of a constitution is not the definitive reason for a country being democratic. Many non-democratic or authoritarian nations also possess their own constitutions to provide a legal framework for governance without practicing democracy. Consequently, the reason provided does not logically explain the assertion.

Explanation

Parliamentary privileges in India are classified into collective privileges, which belong to the House as a whole, and individual privileges, which are enjoyed by each member personally. Freedom from attendance as a witness is an individual privilege rather than a collective one. According to this immunity, a member of Parliament cannot be compelled to attend as a witness in a court of law when the House is in session. This ensures that a member's primary responsibility toward the legislature is not hindered by judicial proceedings. This privilege is intended to protect the independence of the members and facilitate the smooth functioning of parliamentary business without external interference from the judiciary during session periods.

Explanation

i: TRUE - HC judges are appointed by President (Art.217), not Governor. ii: FALSE - Governor is part of state legislature under Art.168. iii: TRUE - Governor nominates 1/6th of Legislative Council members (Art.171). iv: TRUE - Governor cannot dissolve Vidhan Sabha on his own; acts on advice of Council of Ministers. True statements: i, iii, iv = option C (1,3,4).

Explanation

Article 21 of the Constitution of India provides that no person shall be deprived of his life or personal liberty except according to procedure established by law. The Supreme Court of India has upheld the constitutional validity of capital punishment in landmark judgments such as Jagmohan Singh v. State of Uttar Pradesh (1973) and Bachan Singh v. State of Punjab (1980). The judiciary maintains that the death penalty does not violate Article 21 because the deprivation of life happens through a rigorous legal process and fair trial, which constitutes the procedure established by law. While the court has expanded the scope of Article 21 to include various substantive rights, capital punishment remains a legally sanctioned exception expressly permitted by the text of the Article itself when prescribed by valid legislation and procedural safeguards.

Explanation

Zonal Councils are statutory bodies rather than constitutional bodies because they were created by an Act of Parliament, specifically the States Reorganisation Act of 1956. Constitutional bodies are those established directly by the provisions of the Constitution of India, such as the Finance Commission or the Union Public Service Commission. Since the Zonal Councils derive their authority from legislation and are not mentioned in the text of the Constitution, they do not possess constitutional status. These councils were designed to function as advisory platforms to promote interstate cooperation and resolve disputes between states or between the center and states.

Explanation

The Zabt system, also known as the Dahsala system, was the primary land revenue assessment method introduced by Raja Todar Mal during the reign of Akbar. This system was based on the systematic measurement of land and the calculation of revenue based on the average production and market prices of various crops over the preceding ten years. One-third of the average produce was fixed as the state's share, usually collected in cash. As Akbar expanded his empire into the Deccan, incorporating territories such as Berar, Khandesh, and parts of Ahmednagar, the Mughal administration introduced the Zabt system to these provinces to standardize revenue collection and ensure a stable income for the imperial treasury. The system relied on detailed land surveys and the maintenance of local records by officials like the Qanungo and Patwari.

Explanation

Francisco Pelsaert was a Dutch merchant and an officer of the Dutch East India Company (VOC) who arrived in India in 1620. He resided in Agra for seven years until 1627, which corresponds to the latter part of Emperor Jahangir's reign. During his stay, Pelsaert authored a detailed report known as the Remonstrantie, providing a valuable contemporary account of the Mughal Empire's commercial activities, social conditions, and administrative structure. His writings are particularly recognized for their descriptions of the indigo trade and the life of the common people in northern India during the early 17th century.

Explanation

India maintained a consistent trade surplus during the British Raj because the value of its exports, comprising raw materials like raw cotton, jute, indigo, and food grains, regularly exceeded the value of imported British manufactured textiles and machinery. This resulted in a favorable balance of trade for India in statistical terms. Simultaneously, the concept of the Drain of Wealth, famously articulated by Dadabhai Naoroji, explains that this surplus did not result in an inflow of wealth or bullion into India. Instead, the surplus was siphoned off to Britain to pay for Home Charges, salaries and pensions of British officials, and interest on foreign debt, effectively making the exports unrequited. While both statements are factually true, the Reason describes the nature and utilization of the trade surplus rather than the cause of why the balance of trade was favorable in the first place. The favorable balance was primarily a result of India's role as a primary producer and the forced commercialization of agriculture under colonial trade policies.

Explanation

In the Rigveda, the term Aghanya literally translates to not to be killed or inviolable. This designation was specifically applied to cows, reflecting their immense economic and social importance in the early Vedic pastoral society. Cows were considered a primary form of wealth and were frequently used as a medium of exchange and as gifts to priests. By labeling the cow as Aghanya, the Vedic texts established a religious and social prohibition against its slaughter, emphasizing its sanctity and its vital role in the sustenance and rituals of the community.

Explanation

The eleven-headed depiction of the Bodhisattva Avalokiteshvara, known as Ekadasamukha, is a unique iconographic feature found in Cave 41 of the Kanheri Caves in Mumbai. This representation is the only one of its kind in Indian rock-cut architecture. The sculpture portrays the deity with ten additional heads stacked in tiers above the central head, symbolizing his ability to look in all directions to witness and alleviate the suffering of all sentient beings. This specific form marks the evolution of Mahayana and early Vajrayana influences within the Buddhist monastic complex at Kanheri, dating approximately to the late 5th or early 6th century CE. While this multi-headed form became highly prominent in East Asian Buddhist art, particularly in China and Japan, its solitary Indian sculptural occurrence is preserved at this site.

Explanation

The Guntupalli Buddhist site in the West Godavari district is home to significant early rock-cut monuments, including a rare circular chaitya griha and several viharas carved into sandstone hills during the 2nd century BCE. These structures represent the transition from wood to stone in religious architecture. Throughout the Eastern Deccan, the practice of excavating chaityas and viharas into rock faces was a standard and widespread architectural tradition. This region, encompassing parts of modern-day Andhra Pradesh, saw the development of numerous such rock-cut complexes in its hilly tracts, where the durable nature of carved stone provided permanent and stable environments for Buddhist monastic communities to reside and worship.

Explanation

Under Article 249 of the Indian Constitution, if the Rajya Sabha declares by a resolution supported by not less than two-thirds of the members present and voting that it is necessary or expedient in the national interest that Parliament should make laws with respect to any matter enumerated in the State List, it becomes lawful for Parliament to legislate on that subject. According to Article 249(2), such a resolution remains in force for such period, not exceeding one year, as may be specified therein. However, the Rajya Sabha can pass subsequent resolutions to extend this period for further intervals, each not exceeding one year at a time. A law made by Parliament under this provision ceases to have effect on the expiration of a period of six months after the resolution has ceased to be in force.

Explanation

The inscriptions found on the Barabar hill caves date back to the Mauryan period in the 3rd century BC, specifically during the reign of Emperor Ashoka, who ruled from approximately 268 to 232 BC. The 6th century BC was the era of the Mahajanapadas and the early lives of Gautama Buddha and Mahavira, which predates the Mauryan dynasty and the systematic development of these rock-cut architectural structures. Ashoka's inscriptions in these caves typically record his regnal years, such as the 12th and 19th years of his consecration, confirming their 3rd century BC origin.

Explanation

Matsya Mahajanapada was one of the sixteen great kingdoms (Mahajanapadas) that existed in ancient India during the 6th century B.C. It occupied the territory in the present-day state of Rajasthan, encompassing the modern districts of Jaipur, Alwar, and Bharatpur. The capital of this kingdom was Viratanagara, which is identified with the modern town of Bairat in the Jaipur district. Named after its founder, King Virata, the region is frequently mentioned in the Mahabharata as the place where the Pandavas spent their final year of exile in incognito. Geographically, it was situated to the south of the Kurus and west of the Yamuna River, which served as the boundary between Matsya and the Surasena Mahajanapada.

Explanation

Gandhara Art (A) flourished primarily under the Kushanas (3), who were great patrons of this hybrid school of art that combined Indian Buddhist iconography with Graeco-Roman stylistic elements. The Junagarh (B) Rock Inscription is a significant historical document attributed to the Shaka ruler Rudradaman I (4), describing his achievements and the repair of the Sudarshana Lake. Milinda-panho (C) is a famous Buddhist text recording the philosophical dialogue between the Indo-Greek King Menander (1) and the monk Nagasena. Taxila (D) is associated with the Patika (2) Rock Inscription, an important epigraphic record of the Indo-Scythian period found in the region of the ancient university city.

Explanation

Hussain Shah Sharqi was the final independent ruler of the Jaunpur Sultanate, reigning from 1458 until the state was annexed. His tenure was defined by a long-standing rivalry with the Lodi Sultanate of Delhi. In 1479, Bahlul Lodi decisively defeated Hussain Shah and captured Jaunpur, forcing the Sharqi ruler to flee to Bihar and eventually to Bengal. With his defeat and the subsequent administrative integration of Jaunpur into the Delhi Sultanate, the Sharqi dynasty came to an end, making Hussain Shah the last sovereign ruler of the state.

Explanation

The Third Anglo-Maratha War (1817–1818) took place during the tenure of Lord Hastings (the Marquess of Hastings), who served as the Governor-General of India from 1813 to 1823. This conflict led to the formal end of the Maratha Empire and the annexation of their territories by the British East India Company. Lord Cornwallis served as Governor-General during an earlier period, from 1786 to 1793 and briefly again in 1805. His significant military involvement was in the Third Anglo-Mysore War (1790–1792), and he had died over a decade before the Third Anglo-Maratha War commenced.

Explanation

Adinatha is associated with the Bull symbol as the first Tirthankara of the current cosmic era. Mallinatha is uniquely identified by the Water Jar or Kalasha symbol among the twenty-four Tirthankaras. Parshvanatha is represented by the Snake cognizance, often shown as a protective multi-headed cobra canopy. Sambhavnatha is designated with the Horse as his specific iconographic mark according to Jain tradition.

Explanation

The Tamralipta Jatiya Sarkar was a parallel government established in the Tamluk subdivision of Midnapur district, Bengal, as a part of the Quit India Movement. It was formally inaugurated on December 17, 1942, following a period of intense revolutionary activity against British rule. Under the leadership of figures like Satish Chandra Samanta, this self-governing body functioned effectively until September 1944. It maintained its own administrative structure, including a police force known as the Vidyut Vahini, a judiciary, and departments for health, education, and revenue, representing one of the most successful instances of local self-rule during the Indian independence movement.

Explanation

The Meerut Conspiracy Case (1929) involved the arrest and trial of 31 prominent labor leaders and communists, including three British nationals, on charges of conspiring against the British Crown to establish a branch of the Communist International in India. The trial lasted for more than four years and became a cause célèbre for the international labor movement and advocates of civil liberties. The perceived injustice of the British government's crackdown on trade union activities drew widespread condemnation from around the world. Distinguished figures such as Albert Einstein, H.G. Wells, Harold Laski, Romain Rolland, and Franklin D. Roosevelt voiced their support for the convicts, viewing the case as a politically motivated attempt to suppress the rights of workers. This immense global publicity and pressure from international intellectual circles significantly embarrassed the British administration and eventually led to the mitigation of the harsh sentences initially imposed on the defendants.

Explanation

Lord Macaulay made this observation during his speech in the British House of Commons on July 10, 1833, while debating the Government of India Bill, which became the Charter Act of 1833. He was addressing the peculiar political status of the East India Company, which had transitioned from a private trading corporation into a sovereign governing body over a vast empire. Macaulay argued that while the Company's dual nature as a merchant and a ruler was logically an anomaly, it was a necessary and integrated part of the broader British administrative system in India, which itself was built upon unique historical circumstances and unconventional structures. This speech supported the legislative transition that ended the Company's commercial functions entirely, making it a trustee for the Crown in the administration of India.

Explanation

Pabna Revolt (1873) and Deccan Riots (1875) are correctly matched. Sanyasi Revolt began 1763 (not 1894). Kol Uprising was 1831-32 (not 1870). Both C and D have wrong years; standard UPPSC key marks D (Kol Uprising 1870) as the incorrectly matched pair since the Kol Uprising is well-documented as 1831-32.

Explanation

Raja Ram Mohan Roy strongly opposed the Jury Act of 1826 because it introduced religious discrimination into the judicial process. The Act stipulated that while Christians could sit on juries for the trial of both Christians and non-Christians, Hindus and Muslims were prohibited from sitting on juries for the trial of Christians. Roy viewed this as a blatant violation of the principle of equality and a systematic degradation of the native population. He organized a protest against this measure and sent a petition to the British Parliament, signed by both Hindus and Muslims, highlighting the unfairness of incorporating religious distinctions into the administration of justice. This protest was one of the earliest examples of constitutional agitation in India aimed at securing civil rights and legal equality.

Explanation

The Dutch East India Company, established in 1602, set up a wide network of trading posts and factories across the Indian subcontinent to trade in spices, cotton, indigo, silk, and saltpetre. Their first factory was established at Machilipatnam in 1605. On the Coromandel Coast, they held Nagappattinam, which eventually became their headquarters in South India. In Bengal, Chinsura was a major Dutch stronghold. Along the western coast, they established influential trading centres at Surat and Bharuch. To access the hinterland markets for textiles and saltpetre, they founded factories in Agra, Ahmedabad, and Patna. Additionally, they expanded their influence on the Malabar Coast by capturing Cochin from the Portuguese in 1663. Every location mentioned in the sets provided served as a Dutch trading centre at various points during the seventeenth and eighteenth centuries.

Explanation

Following the 1923 elections, the Swaraj Party emerged as the largest opposition group in the Central Legislative Assembly but lacked an outright majority to defeat government measures. To strengthen their position, the Swarajists, led by Motilal Nehru, formed a coalition with the Independent group and some Liberals. M.A. Jinnah, as the leader of the Independents, supported the Swaraj Party in this legislative front, which came to be known as the Nationalist Party. This cooperation was instrumental in securing majorities to outvote the government on critical issues, including the rejection of the 1924 budget and the passage of the resolution demanding a Round Table Conference to discuss constitutional reforms for India. Jinnah played a key role in this unified opposition, helping the Swarajists maintain a strategy of consistent obstruction against the British executive within the assembly.

Explanation

Gopal Krishna Gokhale founded the Servants of India Society on June 12, 1905, in Pune, Maharashtra. The society was established with the aim of training national missionaries for the service of India and promoting the true interests of the Indian people through constitutional means. Members committed themselves to a life of poverty and dedicated service, focusing on social reforms, education, and the upliftment of the underprivileged. The organization played a vital role in fostering a spirit of selfless devotion to the country and addressing issues such as sanitation, healthcare, and the removal of untouchability during the Indian independence movement.

Explanation

In 1303, Sultan Alauddin Khalji dispatched a military expedition to the Kakatiya kingdom under the command of Malik Fakhruddin Juna and Malik Jhaju. This campaign was launched from Bengal while the Sultan was personally engaged in the siege of Chittor. The Khalji army reached the vicinity of Warangal but was decisively defeated by the forces of the Kakatiya ruler, Prataparudra II, at the Battle of Upparapalli. The Sultanate's troops suffered significant casualties and were forced to retreat, marking a notable failure in Alauddin Khalji's early attempts at Deccan expansion. This defeat prompted the Sultan to organize a more robust expedition in 1309 under the leadership of Malik Kafur, which eventually succeeded in extracting tribute from the Kakatiya dynasty.

Explanation

Paradip Port, situated at the confluence of the Mahanadi River and the Bay of Bengal in Odisha, is a premier artificial, deep-water, all-weather port on India's east coast. Among the major ports listed, Paradip is recognized for its significant draft capacity, which reached approximately 17.1 meters by 2017. This depth is maintained through consistent dredging, allowing the port to accommodate large Cape-size vessels and heavy bulk carriers. It serves as a vital hub for the maritime trade of iron ore, coal, and crude oil, leveraging its deep-water approach to handle high-tonnage cargo efficiently.

Explanation

The Siachen Glacier is located in the eastern Karakoram range in the Himalayas, just northeast of the point NJ9842 where the Line of Control between India and Pakistan ends. It is the largest glacier in the Karakoram and the second-longest in the world's non-polar areas, stretching approximately 76 kilometers in length. The glacier covers an area of about 700 square kilometers and lies at an altitude ranging from approximately 5,753 meters at its head to 3,620 meters at its terminus. Its massive scale and longitudinal extent make it the most significant glacial system in the Indian subcontinent, serving as the primary source for the Nubra River, which flows into the Shyok River and eventually joins the Indus.

Explanation

According to the 2011 Census, the Scheduled Tribe population in Uttar Pradesh is approximately 1,134,273, which represents 0.57 percent of the total state population. This constitutes the lowest proportion for the four states. The tribal population is primarily concentrated in specific districts such as Sonbhadra and includes communities like the Gond, Kharwar, and Tharu. Due to the extremely large total population of the state, the demographic share of Scheduled Tribes remains the smallest in this set.

Explanation

The Agulhas Current is a prominent warm western boundary current located in the South West Indian Ocean. It flows southward along the east coast of Africa, transporting warm, saline tropical waters from the equatorial regions toward the Southern Ocean. As a western boundary current, it is characterized by its high velocity and significant heat transport, which plays a crucial role in the regional climate of Southern Africa and influences the global thermohaline circulation through the shedding of Agulhas rings into the Atlantic Ocean.

Explanation

Nathu La is a prominent mountain pass located in the Himalayas along the Indo-China border in the state of Sikkim. It sits at an elevation of approximately 4,310 meters and serves as one of the three open trading border posts between India and China, alongside Shipki La and Lipulekh. Meghalaya, while a mountainous state in Northeast India, is part of the Shillong Plateau and comprises the Garo, Khasi, and Jaintia Hills, which are distinct from the Himalayan range where Nathu La is situated. Consequently, pairing Nathu La with Meghalaya is geographically inaccurate as the pass is located hundreds of kilometers away in the state of Sikkim.

Explanation

Aberdeen earned the title of the oil capital of Europe following the discovery of significant North Sea oil and gas reserves in the 1960s and 1970s. The city's strategic location on the northeast coast of Scotland made it the ideal logistical and administrative base for offshore operations. It became the principal onshore support center for the United Kingdom's energy sector, hosting the headquarters of major international oil companies and a vast network of supply chain and engineering firms. The presence of the busy Aberdeen Harbour and the nearby heliport at Dyce, which is one of the world's busiest for offshore personnel transfers, further solidified its status as the primary hub for the European offshore energy industry.

Explanation

To the north, it is bordered by Lebanon. To the northeast, it shares a boundary with Syria. To the east, Israel shares its longest land border with Jordan. To the southwest, it is bordered by Egypt along the Sinai Peninsula. Additionally, Israel shares boundaries with the Palestinian territories of the West Bank to the east and the Gaza Strip to the west. These four countries—Lebanon, Syria, Jordan, and Egypt—are the internationally recognized neighbors that define Israel's immediate terrestrial perimeter.

Explanation

The Colorado Plateau is an extensive physiographic province in the Southwestern United States, covering approximately 337,000 square kilometers. It is centered on the Four Corners region, spanning parts of Arizona, Utah, Colorado, and New Mexico. The plateau is characterized by its high elevation and the presence of largely horizontal sedimentary rock layers that have been dramatically carved by the Colorado River and its tributaries. Its total area and geographic scale represent a vast, elevated stable block of the Earth's crust that stands distinct from the surrounding fractured landscapes. Its formation resulted from massive tectonic uplift that raised the entire region as a single structural unit.

Explanation

The Champaran Satyagraha of 1917 was Mahatma Gandhi's first major movement in India, focused on the plight of indigo farmers in Bihar under the Tinkathia system. This was followed by the Ahmedabad Mill Strike in February 1918, where Gandhi intervened in a labor dispute between mill owners and workers regarding wages and the plague bonus. Shortly after, the Kheda Peasant Struggle began in March 1918 in Gujarat to support farmers who were unable to pay land revenue due to crop failure. Finally, the Satyagraha against the Rowlatt Act was organized in early 1919 as a nationwide protest against the repressive legislation that allowed for detention without trial. This order correctly traces Gandhi's early political activities from 1917 to 1919.

Explanation

The Sabarigiri project is a major hydroelectric venture located in the Pathanamthitta district of Kerala, utilizing the waters of the Pamba and Kakki rivers to generate power. The Ghatprabha project is an important irrigation scheme in the Belagavi district of Karnataka, involving the Hidkal dam across the Ghatprabha river to support agricultural activities in the region. The Ramganga project, situated in Uttarakhand, functions as a multipurpose project that serves several objectives including irrigation, hydroelectric power generation, and flood control. While the Idukki project is one of the largest hydroelectric projects in India, it is not a thermal power station, making the remaining three pairs the only correctly matched descriptions in the list.

Explanation

The Dudhsagar waterfall is located on the Mandovi River in the state of Goa and is known for its milky white appearance. The Duduma waterfall is formed by the Machhkund River and is situated in the Koraput district of Odisha. The Gokak waterfall is created by the Ghatprabha River in the Belagavi district of Karnataka, featuring a horseshoe shape similar to Niagara Falls. The Jog waterfall, also known as Gerosoppa Falls, is one of the highest plunge waterfalls in India and is located on the Sharavati River in the Shimoga district of Karnataka.

Explanation

The Gondwana rock system is the primary source of coal in India, accounting for approximately 98 percent of the country's total coal reserves and nearly 99 percent of its annual production. These deposits were formed during the Upper Paleozoic era, specifically from the Carboniferous to the Jurassic periods, roughly 250 million years ago. The coal found in this system is mainly of the bituminous variety and is deposited in extensive sedimentary layers within structural troughs. The most significant coalfields of this system are located in the Damodar Valley, the Son Valley, the Mahanadi Valley, and the Godavari and Wardha valleys. Gondwana coal is essential for India's heavy industries and power generation due to its high calorific value compared to younger deposits.

Explanation

The Salem Steel Plant, located in Tamil Nadu, is situated far from the primary coking coal and iron ore belt of the Chotanagpur Plateau, where the majority of Indias integrated steel plants are concentrated. While it utilizes magnetite iron ore from the local Kanjamalai hills, the plant lacks immediate access to high-quality metallurgical coal, which must be transported over long distances from the eastern coalfields or imported through ports. Its location was primarily determined by regional development goals and market demand rather than the classic Weberian principle of proximity to bulky raw material sources like coal and hematite iron ore.

Explanation

The Red Sea represents a juvenile ocean basin formed by the divergence of the African and Arabian tectonic plates. This plate motion has created a linear rift system where the Earth's crust is being pulled apart. The most prominent geological feature of this rift is the central, linear depression known as an axial trough. This trough is the site of active seafloor spreading, where rising magma from the mantle creates new oceanic crust. The presence of this deep, narrow, and continuous longitudinal depression along the center of the rift is why the Red Sea is classified as an axial trough. It marks the transition from continental rifting to the formation of a new oceanic basin.

Explanation

The Tropic of Cancer is a major circle of latitude located at approximately 23° 26' North of the Equator. In India, this line passes through eight states: Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura, and Mizoram. Gujarat represents the westernmost part of this path in India. The line further extends eastward through the central region of Chhattisgarh and continues through the state of Jharkhand. These three states are geographically positioned such that the 23.5° North latitude intersects their territories.

Explanation

The geographical distribution of these tribes follows the physical layout of the hills in Northeast India from west to east. The Garo Hills form the westernmost part of the Meghalaya plateau. Moving eastward, the central part of the plateau is occupied by the Khasi Hills, followed by the Jaintia Hills in the easternmost section of Meghalaya. The Naga Hills are located even further east, primarily within the state of Nagaland. This spatial arrangement across the states of Meghalaya and Nagaland defines the west-to-east progression of the Garo, Khasi, Jaintia, and Naga communities.

Explanation

The Ludwig Canal, formally known as the Ludwig-Danube-Main Canal, is situated in the state of Bavaria in Southern Germany. Completed in 1846 under the reign of King Ludwig I, it was designed to connect the Danube River at Kelheim with the Main River at Bamberg. By bridging the European watershed, the canal established a continuous inland waterway between the Rhine river basin and the Danube river basin. This strategic route allowed for transport between the North Sea and the Black Sea. While the modern Rhine-Main-Danube Canal eventually superseded it for large-scale commercial shipping, the Ludwig Canal remains a significant historical inland waterway in the southern German landscape.

Explanation

Fazendas are extensive plantations in Brazil primarily dedicated to the large-scale cultivation of coffee. These agricultural estates became the backbone of the Brazilian economy during the coffee boom of the nineteenth century, centered largely in the fertile regions of Sao Paulo and Minas Gerais. A typical fazenda functioned as a self-sufficient production unit equipped with specialized infrastructure for processing, including drying floors and machinery to prepare the coffee beans for global export. This plantation system played a critical role in establishing Brazil as the preeminent global supplier of coffee.

Explanation

The capital of the Maldives is Male, which is the most populous city and the administrative center of the archipelagic nation located in the Indian Ocean. Malabo is the capital of Equatorial Guinea, a country situated on the west coast of Central Africa. Malabo is located on the island of Bioko, far removed from the South Asian region where the Maldives is situated.

Explanation

Kumari is the traditional name for shifting cultivation practiced in the hilly tracts of the Western Ghats, particularly in parts of Kerala and Karnataka. Waltre, also known as Valra, is the specific term used for slash-and-burn agriculture in the south-eastern region of Rajasthan. Jhum cultivation is the most widely recognized nomenclature for shifting agriculture across North-east India, involving states like Assam, Meghalaya, and Nagaland. Dahiya is the local term used for shifting cultivation in the states of Madhya Pradesh and Chhattisgarh, where it is traditionally practiced by various tribal communities.

Explanation

Bharat Aluminium Company Limited (BALCO) was established as the first public sector aluminium company in India with its primary integrated plant located at Korba in Chhattisgarh. Hindustan Aluminium Corporation Limited (HINDALCO) operates its massive alumina refinery and smelter at Renukut in the Sonbhadra district of Uttar Pradesh, utilizing power from the Rihand Dam. Indian Aluminium Company (INDAL), which was later acquired by Hindalco, set up a significant smelting facility at Hirakud in Odisha to take advantage of the hydroelectricity generated by the Hirakud Dam. National Aluminium Company Limited (NALCO) is a major public sector enterprise that established its large-scale bauxite mining and alumina refining complex at Damanjodi in the Koraput district of Odisha.

Explanation

Khartoum, the capital of Sudan, is situated at the confluence of the White Nile and the Blue Nile rivers. Brazzaville, the capital of the Republic of the Congo, is located on the north bank of the Zaire River, which is also known as the Congo River. Rotterdam is a major port city in the Netherlands located within the Rhine-Meuse-Scheldt delta, primarily served by the Rhine. Paris, the capital of France, is centrally located along the banks of the Seine River.

Explanation

Liquefied Petroleum Gas (LPG) is primarily a mixture of propane and butane, both of which are naturally odorless and colorless. For safety purposes, a pungent-smelling chemical compound called ethyl mercaptan (C₂H₅SH), also known as ethanethiol, is added to the gas. This substance has a strong, distinctive stench similar to rotten cabbage or sulfur, which allows people to detect even minute gas leakages easily. Because LPG is highly flammable, the addition of this odorant is a crucial warning mechanism to prevent accidental fires or explosions.

Explanation

The human digestive system is incapable of digesting cellulose because it lacks the specific enzyme, cellulase, required to hydrolyze the β-1,4-glycosidic linkages that hold the glucose units together in cellulose. Diastase is a general term for enzymes that catalyze the breakdown of starch into maltose, such as salivary and pancreatic amylase, both of which are present in the human body. Although both statements are biologically true, the presence of starch-degrading enzymes does not explain the absence of the specific enzymes needed for cellulose digestion.

Explanation

The brain is the central processing unit for pain signals transmitted from throughout the body, yet the brain tissue itself lacks nociceptors, which are the sensory receptors responsible for detecting painful stimuli. While the surrounding structures such as the meninges, the scalp, and the blood vessels are highly sensitive to pain, the brain parenchyma does not contain the nerve endings required to register the physical sensation of being pricked. Consequently, a needle can be inserted into the brain tissue without eliciting a pain response from the organ itself, a biological fact that allows neurosurgeons to perform certain intracranial procedures while the patient remains conscious.

Explanation

Jackals belong to the family Canidae, which includes carnivorous mammals such as dogs, wolves, and foxes. These animals possess paws with soft, fleshy pads and non-retractable claws rather than hooves. Hooves are specialized keratinous coverings found at the tips of the digits of ungulate mammals. Jackals use their clawed paws for traction while running, digging, and capturing prey, a biological adaptation distinct from the solid or split hooves used by ungulates for supporting body weight during locomotion on various terrains.

Explanation

Fructose, often referred to as fruit sugar, is a simple monosaccharide found naturally in many plants. It is chemically classified as a ketohexose with the molecular formula C₆H₁₂O₆. Among all naturally occurring carbohydrates, fructose is the sweetest, possessing a sweetness intensity significantly higher than that of both glucose and sucrose. Because it is found in high concentrations in fruits, berries, and honey, it serves as the primary chemical compound responsible for the characteristic sweet taste of these foods. During the ripening process, enzymatic actions often increase the concentration of simple sugars like fructose, which further enhances the fruit's sweetness.

Explanation

Silk is a natural protein fiber produced by certain insects, most notably the larvae of the silkworm Bombyx mori, to build cocoons. It is classified as a natural polymer because it is primarily composed of the protein fibroin, which consists of long chains of amino acids linked together by peptide bonds. These polypeptide chains are organized into a semi-crystalline structure that provides silk with its characteristic strength and lustre. Since it is bio-synthesized within living organisms rather than being chemically synthesized from petroleum-based precursors, it falls into the category of naturally occurring polymers alongside others like cellulose, starch, and DNA.

Explanation

Gastrin is a peptide hormone primarily secreted by G cells in the pyloric antrum of the stomach and the duodenum. Its principal function is the stimulation of gastric acid (hydrochloric acid) secretion from the parietal cells of the stomach, which is essential for the digestion of proteins and the killing of ingested bacteria. Additionally, gastrin stimulates the growth of the gastric mucosa and increases antral muscle contractions. It does not possess a physiological role in the regulation of blood pressure, which is instead governed by systems such as the renin-angiotensin-aldosterone system (RAAS) and various vasoactive substances like vasopressin and atrial natriuretic peptide.

Explanation

Urea, chemically represented by the formula CO(NH₂)₂, is a nitrogenous organic compound known as carbamide. It is the diamide of carbonic acid and serves as the primary nitrogenous waste product of protein metabolism in mammals, excreted through urine. In the history of chemistry, urea is highly significant because it was the first organic compound to be synthesized from inorganic starting materials in a laboratory. This synthesis, performed by Friedrich Wöhler in 1828 using ammonium cyanate, provided the first evidence against the vitalism theory, which proposed that organic compounds could only be created by living organisms through a vital force. Because it contains carbon covalently bonded to nitrogen and oxygen, it is classified as organic. It is widely utilized in agriculture as a concentrated nitrogen fertilizer due to its high nitrogen content of approximately 46 percent.

Explanation

The Rani Jhansi Maritime National Park was established in 1996. Located in the Ritchie's Archipelago within the Andaman and Nicobar Islands, this national park encompasses several islands such as Henry Lawrence Island, John Lawrence Island, and Outram Island. It covers an area of approximately 256 square kilometers and was designated as a protected area to conserve the region's diverse marine life, coral reefs, and mangrove ecosystems. The park provides a vital habitat for endangered species like the dugong, as well as various types of sea turtles and crocodiles.

Explanation

The gallbladder serves as a storage reservoir for bile, a digestive fluid synthesized by the liver. Bile contains bile salts that are critical for the emulsification of fats in the small intestine. Emulsification is the process of breaking down large lipid globules into smaller droplets, which significantly increases the surface area available for the enzyme pancreatic lipase to chemically digest the fats into fatty acids and glycerol. When stones form in the gallbladder, they can block the cystic duct or the common bile duct, preventing bile from reaching the duodenum. This lack of bile severely impairs the body's ability to mechanically break down and subsequently absorb dietary fats.

Explanation

Night blindness, or nyctalopia, is a condition where the eye is unable to adapt to low-light conditions. It is most commonly caused by a deficiency of Vitamin A (retinol), which is a crucial precursor for the synthesis of rhodopsin. Rhodopsin is a biological pigment found in the rod cells of the retina that is responsible for vision in dim light. Since it is primarily a nutritional deficiency disorder resulting from inadequate dietary intake or poor absorption of Vitamin A, it is classified as a deficiency disease rather than a genetic one. While certain inherited retinal degenerations can cause night-time vision loss, the term night blindness in a general clinical and biological context refers to this treatable nutritional condition.

Explanation

Vitamin D is primarily known as the antirachitic factor because it facilitates the intestinal absorption of calcium and phosphate, ensuring proper mineralization of bone tissue. Its deficiency results in skeletal deformities such as rickets in children and osteomalacia in adults. The term antisterility factor refers to Vitamin E (tocopherol), which plays a crucial role in maintaining reproductive health and preventing oxidative damage to reproductive tissues. Vitamin D does not serve this specific function, making the pairing of Vitamin D with the antisterility role incorrect.

Explanation

Iodine is a critical micronutrient required by the thyroid gland to synthesize thyroid hormones, specifically thyroxine (T4) and triiodothyronine (T3). These hormones are essential for regulating the body's metabolic rate, growth, and development. When dietary intake of iodine is inadequate, the thyroid gland is unable to produce sufficient hormones. In response to low hormone levels, the pituitary gland releases higher amounts of Thyroid-Stimulating Hormone (TSH) to stimulate the thyroid. This chronic overstimulation results in the abnormal enlargement of the thyroid gland, a condition clinically known as goitre. Goitre is the most visible manifestation of iodine deficiency disorders and is frequently found in populations living in iodine-deficient geographic regions.

Explanation

Tartaric acid is a naturally occurring white crystalline organic acid found in many plants, particularly in grapes, tamarind, and bananas. It is a dicarboxylic acid with the chemical formula C₄H₆O₆. In grapes, it is the predominant acid and is crucial for the pH levels and flavor profile of the fruit. Tamarind is one of the richest natural sources of this acid, which provides the fruit with its distinctively sour and tangy taste. It also appears in bananas alongside other organic acids, contributing to the fruit's overall acidity and shelf life. Beyond its natural occurrence, it is widely utilized in the food industry as an acidulant and antioxidant.

Explanation

Hydrogen is considered the cleanest fuel because its combustion primarily produces water vapor (H₂O) as the only byproduct. The chemical reaction 2H₂ + O₂ → 2H₂O releases a high amount of energy per unit mass without the emission of carbon dioxide (CO₂), carbon monoxide (CO), sulfur dioxide (SO₂), or particulate matter. Unlike carbon-based fuels, hydrogen does not contribute to the greenhouse effect or acid rain through its direct combustion products. Its high calorific value and carbon-free nature make it the fuel with the least environmental impact among available energy sources.

Explanation

The brain-to-body mass ratio represents the weight of an animal brain as a percentage of its total body weight. According to the biological principle known as Haller's Rule, the relative size of the brain tends to increase as the absolute body size of a species decreases. This occurs because brain mass does not scale linearly with body mass; instead, it follows an allometric power law:

m_brain ∝ m_bodyᵅ

where the exponent α is typically less than 1. Because this exponent is less than 1, smaller organisms maintain a much higher proportion of their mass as brain tissue. Ants exhibit one of the highest ratios known, with the brain constituting approximately 14% to 15% of their total body mass, or a ratio of roughly 1:7. This high neural investment is necessary to manage the complex social communication, colony organization, and navigation required for their survival in a small physical frame.

Explanation

The Doppler effect is the primary principle used for the precise tracking of artificial satellites from Earth. As a satellite moves relative to a ground station, the frequency of the radio signals it transmits is shifted due to their relative motion. This frequency shift, Δf, is determined by the formula Δf = fₛ (v/c) cos θ, where fₛ is the source frequency, v is the satellite's velocity, c is the speed of light, and θ is the angle of the line of sight. By continuously measuring this frequency shift as the satellite passes over the station, ground systems can calculate the satellite's orbital parameters, including its velocity and exact position, with high resolution. This method is the foundation for precise orbit determination systems such as DORIS (Doppler Orbitography and Radiopositioning Integrated by Satellite).

Explanation

The electrical energy consumption in units is calculated using the formula: Energy (in units) = (Total Power (in watts) × Time (in hours))/1000

In this scenario, there are five bulbs, each with a capacity of 100 watts. The total power P is calculated as 5 × 100 = 500 watts. The duration of illumination is given as 20 hours.

Substituting these values into the energy equation: Energy = (500 × 20)/1000 Energy = 10000/1000 Energy = 10 units

One unit of electricity is defined as one kilowatt-hour (kWh), which is the energy consumed by a 1000-watt appliance running for one hour. Since the total consumption here is 10,000 watt-hours, it equals 10 kilowatt-hours.

Explanation

When a solute like sugar is added to a solvent like water to form an unsaturated solution, the sugar molecules break down and occupy the intermolecular spaces present between the water molecules. Because these sugar molecules fit into the existing gaps within the liquid structure of the water rather than displacing the water molecules significantly, the overall volume of the resulting sugar solution remains practically identical to the initial volume of the water used. While the mass of the system increases by the weight of the added sugar and the density increases accordingly, the physical space occupied by the mixture does not undergo a measurable change.

Explanation

A mobile phone charger serves the primary purpose of converting high-voltage alternating current (AC) from a household wall outlet, which is typically 220V or 110V, into a low-voltage direct current (DC) required by the phone's battery, usually around 5V. The internal circuitry of the charger utilizes a step-down transformer to reduce the input voltage to the desired lower level. In modern chargers, this is often part of a Switched Mode Power Supply (SMPS) system where the AC is rectified, switched at high frequencies, and then passed through a compact step-down transformer to provide the safe, low-voltage output necessary for electronic components.

Explanation

Opium is obtained from the milky latex of the unripe seed capsules of the poppy plant Papaver somniferum, which is botanically the fruit. Hing, also known as Asafoetida, is an oleo-gum-resin extracted from the exudates of the thick tap roots or rhizomes of Ferula species. Natural rubber is harvested as latex through incisions made in the bark of the stem of the Hevea brasiliensis tree. Quinine is a well-known alkaloid used in the treatment of malaria and is extracted directly from the bark of the Cinchona tree.

Explanation

Satellite television communication relies on high-frequency microwave signals, typically in the Ku-band, which have very short wavelengths. When these signals encounter rain, the water droplets—which have a physical size comparable to the wavelength of the radio waves—act as obstacles. These droplets cause the electromagnetic energy to scatter or disperse in multiple directions instead of maintaining a direct line-of-sight path to the dish antenna. This dispersion significantly reduces the power density of the signal reaching the receiver's focal point. While absorption also occurs, the scattering or dispersion of the signal away from the antenna is a primary physical reason for the drop in signal-to-noise ratio that results in a loss of reception.

Explanation

Nagaland was the only state in India to record a negative decadal growth rate during the 2001–2011 census period. According to the Census of India 2011, the population of the state decreased from 1,988,636 in 2001 to 1,978,502 in 2011, resulting in a negative growth rate of approximately -0.58 percent. This decline is largely attributed to the correction of inflated population figures reported in the previous 2001 census, as well as more rigorous data collection and verification processes implemented by the Census Commissioner during the 2011 enumeration cycle.

Explanation

The World Health Organization reported that infectious and parasitic diseases accounted for approximately 16.5 million deaths in 1993, representing a significant portion of global mortality during that period. This high death toll was driven by the prevalence of diseases such as tuberculosis, malaria, and various diarrheal infections. Urbanization serves as a critical factor in this epidemiological landscape because rapid, unplanned urban growth often results in overcrowding, substandard housing, and a lack of basic infrastructure for clean water and sanitation. These conditions create ideal environments for the rapid transmission of pathogens and the proliferation of disease vectors. Since the late 20th century, the failure to integrate health planning into urban development has been a primary reason for the sustained high impact of infectious diseases on human populations, particularly in developing nations.

Explanation

A diamond exhibits exceptional brilliance because it has a very high refractive index of approximately 2.42. According to the relationship sin C = 1/n, where n is the refractive index, the critical angle C for diamond is remarkably small, about 24.4°. When a diamond is cut with precise mathematical proportions, light entering the stone strikes the internal pavilion facets at angles exceeding this critical angle. This causes the light to undergo multiple total internal reflections before exiting through the top of the diamond. This internal trapping and concentration of light rays result in the intense sparkle and fire associated with the gemstone.

Explanation

Project Saksham is a major information technology infrastructure project approved by the Cabinet Committee on Economic Affairs in September 2016 to support the rollout of the Goods and Services Tax. It involves the modernization and integration of the IT systems of the Central Board of Excise and Customs, now known as the Central Board of Indirect Taxes and Customs. The project serves as the technological backbone required for the implementation of GST, enabling the seamless exchange of data with the Goods and Services Tax Network. Beyond GST, Saksham facilitates the digital transformation of indirect tax administration, supporting initiatives like the Single Window Interface for Facilitating Trade and the Indian Customs Electronic Commerce Gateway. By upgrading legacy systems to a robust digital environment, the project aims to enhance the ease of doing business and improve the efficiency of tax collection and taxpayer services in India.

Explanation

Start-ups require diverse financial and strategic support across different stages of their lifecycle, which are typically fulfilled by alternative financing mechanisms rather than traditional bank loans. Angel investors are high-net-worth individuals who provide crucial seed capital and mentorship at the nascent stages of a business. Venture capital firms offer larger scales of institutional funding and professional management expertise to help businesses scale during rapid growth phases. Crowdfunding utilizes digital platforms to raise small amounts of capital from a large number of individual contributors, simultaneously serving as a tool for market validation and public engagement. These various sources collectively address the specific requirements of start-ups regarding capital infusion, networking, and industry guidance.

Explanation

The SEZ India mobile app was launched by the Ministry of Commerce and Industry in January 2017 as part of the government's Digital India initiative. Special Economic Zones (SEZs) are governed by the SEZ Act of 2005 and are under the administrative jurisdiction of the Department of Commerce, which functions under this ministry. The app was designed to enhance the ease of doing business by providing developers and units within these zones with a platform to track their transactions, view status updates on applications, and access information regarding SEZ policies and notifications in real time.

Explanation

The New Development Bank (NDB) was established by the BRICS nations (Brazil, Russia, India, China, and South Africa) following the signing of the Agreement on the New Development Bank during the sixth BRICS summit in Fortaleza, Brazil, in July 2014. Headquartered in Shanghai, China, the bank was created to mobilize resources for infrastructure and sustainable development projects in BRICS and other emerging market economies and developing countries. The bank represents a collective effort by these five major emerging economies to create a multilateral financial institution that complements the existing functions of global and regional financial organizations like the World Bank and the International Monetary Fund. K. V. Kamath from India served as the bank's first president, emphasizing its role in fostering cooperative financial development among the member nations.

Explanation

Launch dates: PM Jan Dhan Yojana (28 Aug 2014/iv), Make in India (25 Sep 2014/iii), Sukanya Samriddhi Yojana (22 Jan 2015/i), Atal Pension Yojana (9 May 2015/ii). Chronological: iv, iii, i, ii = Option A.

Explanation

The Rashtriya Swasthya Bima Yojana (RSBY) was launched in 2008 by the Ministry of Labour and Employment under the Unorganised Workers' Social Security Act, 2008. The scheme was specifically designed to provide health insurance coverage to Below Poverty Line (BPL) households and other categories of workers in the unorganized sector, such as street vendors, beedi workers, domestic workers, and building and other construction workers. It offers a cashless, smart card-based health insurance cover of up to ₹30,000 per annum per family on a floater basis. The focus on the unorganized sector addresses the lack of formal social security and the high out-of-pocket expenditure on healthcare faced by workers who do not have regular employer-employee relationships or structured benefits.

Explanation

The Eleventh Five-Year Plan (2007–2012) established a set of twenty-seven monitorable targets across various sectors, including health and education. In the health sector, one of the primary objectives was to significantly lower the Infant Mortality Rate (IMR) from the baseline level existing at the start of the plan. The specific target set by the Planning Commission was to reduce the IMR to 28 per 1,000 live births by the conclusion of the plan period in 2012. This goal was aligned with broader efforts to improve maternal and child health services, enhance immunization coverage, and promote institutional deliveries across the country.

Explanation

Meerut is the primary center for the manufacturing of sports goods in Uttar Pradesh, particularly famous for cricket equipment. Bareilly is a significant hub for the matchbox industry and is also well-known for its furniture and zari-zardozi work. Moradabad is internationally recognized as Pital Nagri or the Brass City due to its massive production and export of traditional and modern brassware. Saharanpur is globally renowned for its heritage of wood carving, where skilled artisans create intricate designs on wooden furniture and decorative items.

Explanation

The United Nations adopted a formal definition of absolute poverty during the World Summit for Social Development held in Copenhagen in 1995. According to the Copenhagen Declaration, absolute poverty is a condition characterized by severe deprivation of basic human needs, including food, safe drinking water, sanitation facilities, health, shelter, education, and information. This definition was significant because it moved beyond purely income-based measures to include access to essential social services and infrastructure. The 1995 summit resulted in a global commitment to eradicate absolute poverty, acknowledging that it is a multidimensional issue requiring comprehensive policy interventions at both national and international levels.

Explanation

Leisure is not one of the four key dimensions used by the World Economic Forum to calculate the Global Gender Gap Index. The index is specifically designed to measure gender-based gaps in access to resources and opportunities across four specific areas: Economic Participation and Opportunity, Educational Attainment, Health and Survival, and Political Empowerment. Because the index focuses on indicators like labor force participation, literacy, life expectancy, and representation in parliament, recreational or leisure-based metrics are entirely excluded from the methodology.

Explanation

The Sufi Circuit was not part of the thematic circuits recognized under the Swadesh Darshan Scheme by the Ministry of Tourism in early 2017. Although the scheme aimed to develop theme-based tourism across India, the Sufi theme was formally added as the fifteenth thematic circuit only later in the year 2017. Consequently, it was not included in the list of thirteen circuits that governed the scheme's implementation during its initial phase and the period leading up to mid-2017.

Explanation

The Government of Uttar Pradesh, exercising its powers under the Minimum Wages Act, 1948, revises the minimum wage rates twice a year based on the Consumer Price Index to mitigate the impact of inflation. For the period starting 1 April 2017 and ending 30 September 2017, the state labor department set the minimum wage for unskilled labor at ₹7,388.93 per month. This figure represents the combination of the basic pay and the Variable Dearness Allowance (VDA) calculated for that specific half-year interval. For administrative and examination purposes in 2017, this mandatory minimum compensation for unskilled workers was rounded and officially cited as ₹7,400 per month.

Explanation

Haryana represents a significant socio-economic paradox in India where high economic performance coincides with poor gender indicators. According to the 2011 Census, which was the benchmark data available in 2017, Haryana recorded the lowest sex ratio among all Indian states at 879 females per 1,000 males. In stark contrast, the state consistently ranked among the highest in terms of per capita income and industrial development, largely due to its proximity to the National Capital Region and the presence of major commercial hubs like Gurugram. This situation reflects a deep-seated preference for male children and the prevalence of female foeticide that persisted despite rapid modernization and wealth accumulation in the region.

Explanation

The National Family Health Survey 3 (NFHS-3), conducted in 2005-06, provides comprehensive data on healthcare seeking behavior in India. The survey results indicated that the private medical sector remains the predominant source of healthcare for the majority of the population. Specifically, the data showed that the private medical sector is the primary source of health care for 70 percent of households in urban areas. This reliance on private providers is often attributed to factors such as the perceived better quality of care, more convenient timings, and the geographical proximity of private clinics compared to public health facilities. Even in rural areas, the private sector accounted for 63 percent of healthcare visits, but the 70 percent figure for urban households highlights the heavy commercialization and preference for private medical services in cities.

Explanation

The Economic Survey 2015-16 introduced the term Chakravyuha Challenge to describe a fundamental structural weakness in the Indian economy. It refers to the transition of the economy from a socialist model characterized by limited entry (the License Raj) to a market-oriented system that allows entry but lacks a functional exit mechanism. While the 1991 reforms made it significantly easier for new firms to enter the market, legal, political, and institutional barriers continued to prevent inefficient or failing firms from exiting. This inability to exit leads to the misallocation of capital, labor, and land, as resources remain trapped in non-productive firms. The survey highlighted that this lack of exit creates a situation analogous to the mythological Chakravyuha, where the ability to enter is not matched by the ability to leave, resulting in the twin balance sheet problem and suppressed economic growth.

Explanation

The hierarchy of biological organization reflects increasing levels of complexity and spatial scale. It begins at the level of the individual organism. A Population comprises a group of individuals belonging to the same species that inhabit a specific geographical area. When multiple populations of different species interact within the same environment, they form a Community. An Ecosystem is a more complex level that includes the biological community plus the physical abiotic factors with which it interacts. A Landscape refers to a heterogeneous geographic area characterized by a mosaic of interacting ecosystems. This logical progression from simpler to more inclusive units defines the standard ecological order leading toward the biosphere.

Explanation

Respirable Suspended Particulate Matter (RSPM) refers to the fraction of airborne particles that are small enough to bypass the natural filtration mechanisms of the upper respiratory tract—such as the nose and throat—and penetrate deep into the lungs. In environmental science and public health standards, RSPM is generally defined as particulate matter with an aerodynamic diameter of less than 10μm (PM10). However, the specific fraction that is capable of reaching the gas-exchange or alveolar region of the lower respiratory system is more precisely defined as particles having a diameter of less than 5μm (often specifically 4μm or 2.5μm depending on the specific respiratory model). Particles larger than 5μm are typically deposited in the upper airways and are not considered part of the deeper respirable fraction.

Explanation

Uttar Pradesh is divided into 9 agro-climatic zones as classified by the Planning Commission and the Indian Council of Agricultural Research (ICAR). This classification is based on variations in soil types, rainfall, temperature, and water resources across the state to optimize agricultural planning. These nine zones are the Bhabhar and Terai Zone, Western Plain Zone, Mid-Western Plain Zone, South-Western Semi-Arid Zone, Central Plain Zone, Bundelkhand Zone, North-Eastern Plain Zone, Eastern Plain Zone, and the Vindhyan Zone. Each zone exhibits distinct environmental characteristics, such as the high humidity and rainfall of the Terai region compared to the plateau topography and water-scarce conditions found in the Bundelkhand and Vindhyan regions. This zoning helps the government implement region-specific agricultural strategies and crop diversification programs suitable for the local ecology.

Explanation

Climate change manifests in India through an increased frequency and intensity of extreme weather events such as droughts, floods, and erratic monsoons. These events directly disrupt agricultural cycles and reduce crop yields, creating significant threats to food security. In a country where a large percentage of the population depends on climate-sensitive sectors for their livelihood, the resulting scarcity of resources and economic instability lead to heightened competition, forced migration, and rural distress. This chain of causality demonstrates that the repercussions on food security are a primary driver behind the rising social tensions and communal friction observed across different regions.
