UPPSC Prelims 2021 Question Paper with Answers & Explanations

Explanation

The Mughal Empire is characterized by historians as a military state because it was established through conquest and maintained its authority through a sophisticated military-bureaucratic apparatus. The entire structure of the Central Government was built upon the Mansabdari system, which assigned military ranks to all civil and executive officers, requiring them to maintain a specific number of troops. The vitality and efficiency of the administration, especially in revenue collection and territorial expansion, were directly dependent on the military strength of the Emperor and his ability to command the loyalty of his military officers. Consequently, the central administration was essentially an extension of the military organization, making the dependence on military power the primary reason for the state's classification as a military state.

Explanation

Explanation

Latvia is situated in Northern Europe at a latitude of approximately 57°N, far outside the tropical zone required for the growth of cocoa. The cocoa plant, Theobroma cacao, is an equatorial crop that thrives only in hot, humid climates with stable temperatures between 21°C and 32°C and significant year-round rainfall. Because Latvia experiences cold winters and a temperate climate, it is climatically incapable of producing cocoa beans. While the nation has a historical tradition of chocolate manufacturing and processing, it lacks the agricultural environment necessary for primary cocoa production and must import all its raw materials from tropical regions.

Explanation

Article 267 of the Constitution of India authorizes the Parliament to establish a Contingency Fund of India. This fund is placed at the disposal of the President to enable advances to be made for meeting unforeseen expenditure pending authorization by the Parliament. It is operated by executive action, specifically by the Finance Secretary on behalf of the President, and does not require prior legislative approval for withdrawals. Similarly, Article 267(2) allows State Legislatures to establish a Contingency Fund for their respective states, placed at the disposal of the Governor. The corpus of the Contingency Fund of India was significantly increased from ₹500 crore to ₹30,000 crore through the Finance Act of 2021.

Explanation

World Youth Skills Day is observed globally on July 15, following a United Nations General Assembly declaration in 2014. For the year 2021, the theme designated by the United Nations was Reimagining Youth Skills Post-Pandemic. This theme was chosen to address the significant disruptions caused by the COVID-19 pandemic to education and training institutions worldwide. It highlighted the importance of adapting technical and vocational education and training (TVET) to meet new labor market demands and emphasized the resilience of young people. The goal was to initiate a dialogue on how skills development could foster a sustainable and inclusive recovery, ensuring that youth are equipped with the necessary tools to navigate the challenges of a rapidly changing global economy.

Explanation

During the peak of the second wave of the COVID-19 pandemic in 2021, IIT Bombay successfully demonstrated the conversion of a Pressure Swing Adsorption (PSA) nitrogen generator into a PSA oxygen generator. This innovative project was led by the refrigeration and cryogenics laboratory at the institute. The conversion process involved replacing the Carbon Molecular Sieve (CMS) used in nitrogen plants with Zeolite Molecular Sieve (ZMS) and adjusting the operating parameters such as cycle time and pressure. By repurposing existing industrial nitrogen plants, the team was able to produce oxygen with a purity level of 93% to 96%, which met the requirements for medical applications during the critical shortage of liquid medical oxygen. This solution provided a rapid and cost-effective method to augment oxygen supplies using existing industrial infrastructure across the country.

Explanation

Western disturbances are extra-tropical storm systems that originate in the Mediterranean region and travel towards the Indian subcontinent driven by the Subtropical Westerly Jet Stream. During the winter months, these disturbances enter India from the west and northwest, bringing much-needed rainfall to the plains of Punjab, Haryana, and Rajasthan, and snowfall to the Himalayan regions. This winter precipitation is highly beneficial for the cultivation of Rabi crops, particularly wheat, as it provides essential moisture during the growing season after the withdrawal of the summer monsoon.

Explanation

Fly ash is a fine, powdery byproduct generated from the combustion of pulverized coal in thermal power plants. When coal is burned to produce steam for electricity generation, the mineral impurities it contains do not burn; instead, they fuse and remain suspended in the flue gases as tiny particles. These particles, primarily composed of silicon dioxide (SiO₂), aluminum oxide (Al₂O₃), and calcium oxide (CaO), are known as fly ash. While modern plants use electrostatic precipitators to capture this material, any leakage contributes significantly to particulate matter (PM 2.5 and PM 10) pollution in the air and heavy metal leaching in surrounding soil and water bodies.

Explanation

The Uttar Pradesh Swami Vivekanand Etihasik Paryatan Yatra Yojna was launched in 2021 by the State Labour Department through the Uttar Pradesh Labour Welfare Board. This scheme is specifically designed for registered laborers in the state to provide them with financial assistance for visiting religious and historical sites. The government provides a one-time grant of 12,000 rupees to each eligible worker to facilitate travel to prominent cultural and spiritual destinations such as Ayodhya, Mathura, Prayagraj, and Varanasi. The initiative aims to improve the quality of life and provide spiritual enrichment to the working class by making religious tourism accessible to those who may not have the financial means to undertake such journeys independently.

Explanation

The proportion of incident solar radiation reflected by a surface is known as its albedo, expressed as a value between 0 and 1 or as a percentage. Land covered with fresh snow possesses the highest albedo among the given options, typically reflecting between 80 percent and 90 percent of the incoming sunlight back into space. This high reflectivity is due to the white, crystalline structure of the snow, which reflects almost all wavelengths of the visible spectrum. Because it absorbs very little solar energy, fresh snow plays a critical role in regulating local and global temperatures by maintaining a cooling effect on the Earth's surface.

Explanation

The first Indian Institute of Skills (IIS) was established in Kanpur, Uttar Pradesh, following the foundation stone laying ceremony by Prime Minister Narendra Modi in December 2016. This premier institute was conceptualized by the Ministry of Skill Development and Entrepreneurship to provide high-end, industry-oriented technical training to the Indian youth. The Kanpur facility was developed in collaboration with the Institute of Technical Education (ITE) in Singapore, aiming to replicate its successful vocational training model. The initiative focuses on bridging the gap between traditional education and the specific skill requirements of modern industries, providing students with state-of-the-art infrastructure and globally recognized certifications to enhance employability.

Explanation

Barbora Krejcikova is a professional tennis player from the Czech Republic who achieved a significant career milestone at the 2021 French Open. She won her maiden Grand Slam singles title by defeating Anastasia Pavlyuchenkova in the final. This victory made her the first Czech woman to win the singles title at Roland Garros since Hana Mandlikova in 1981. During the same tournament, she also won the women's doubles title, becoming the first female player to sweep both the singles and doubles titles at the French Open since Mary Pierce in 2000.

Explanation

Dr. Sarvepalli Radhakrishnan made this statement in the Constituent Assembly on April 29, 1947, during the discussion on the Interim Report on Fundamental Rights. He characterized the inclusion of Fundamental Rights in the Indian Constitution as a solemn commitment to the citizens of India and a declaration to the international community that the new nation would adhere to the standards of justice and liberty recognized by the civilized world. His words highlighted the dual role of these rights as both a domestic guarantee of freedom and a statement of India's alignment with global humanitarian values.

Explanation

Riboflavin, also known as Vitamin B2, is a water-soluble vitamin that serves as a vital component of the coenzymes flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). These coenzymes are essential for energy production, cellular function, and the metabolism of fats and drugs. A clinical deficiency of riboflavin, known as ariboflavinosis, frequently manifests as cheilosis. This condition involves the inflammation and cracking of the lips, often accompanied by angular stomatitis, which refers to painful fissures at the corners of the mouth. Because riboflavin is necessary for the maintenance of epithelial integrity and mucous membranes, its absence leads to these characteristic lesions and may also cause glossitis, where the tongue becomes swollen and reddened.

Explanation

Mandi is a Late Harappan site located in the Muzaffarnagar district of Uttar Pradesh. It gained archaeological significance in 2000 following the accidental discovery of a massive hoard of ancient jewelry and artifacts by local villagers. The discovery included various gold ornaments, copper vessels, and thousands of beads made of carnelian, agate, and other semi-precious stones. Situated in the fertile Ganga-Yamuna Doab, Mandi represents the eastward spread of the Indus Valley Civilization during its mature and late stages. The abundance of precious metal finds at this site has provided researchers with valuable data regarding the craft specialization and trade networks present in the eastern fringes of the Harappan cultural sphere.

Explanation

Sleeping sickness, also known as African Trypanosomiasis, is a parasitic disease caused by infection with protozoan parasites belonging to the genus Trypanosoma. It is transmitted to humans by the bite of the tsetse fly (Glossina species), which is found only in sub-Saharan Africa. The tsetse fly acquires the parasites from infected humans or animals and passes them on to others through its bite, making it the primary vector for the disease rather than any species of mosquito.

Explanation

According to the 2011 Census of India, Arunachal Pradesh recorded the lowest population density among all Indian states, with a value of 17 persons per square kilometer. This sparse distribution of population is primarily a result of the state's challenging geographical features, including its rugged mountainous terrain, high altitudes, and extensive forest cover that occupies a significant portion of its total land area. The demographic profile is influenced by the physical constraints of the Eastern Himalayas, which limit large-scale human settlement and infrastructural development across the region.

Explanation

Botulism is a severe and potentially fatal paralytic illness caused by the botulinum toxin, which is produced by the bacterium Clostridium botulinum. It is classified as a food-borne intoxication because the disease is caused by the ingestion of pre-formed toxins present in contaminated food, rather than the active growth of bacteria within the host's gastrointestinal tract. The toxin typically develops in anaerobic environments, such as improperly preserved or canned low-acid foods, where the spores can germinate and thrive. The botulinum toxin acts as a potent neurotoxin by blocking the release of the neurotransmitter acetylcholine from motor nerve endings at the neuromuscular junction, leading to symmetrical muscle paralysis and potentially fatal respiratory failure. Because the pathological effects are triggered by the chemical toxin rather than a direct bacterial invasion of tissues, it is defined as an intoxication.

Explanation

The 61st Constitutional Amendment Act, 1988, amended Article 326 of the Constitution of India, which governs the elections to the Lok Sabha and the State Legislative Assemblies. By substituting the words eighteen years for twenty-one years, this amendment lowered the minimum voting age for Indian citizens. The change was implemented to encourage greater participation of the younger generation in the democratic process and to reflect the growing political consciousness among the youth. This legislation received presidential assent and officially came into effect on March 28, 1989, during the tenure of the Rajiv Gandhi government.

Explanation

Radioactivity is a nuclear property because it is a process that originates within the atomic nucleus. It involves the spontaneous emission of particles or electromagnetic radiation, such as alpha particles, beta particles, or gamma rays, from an unstable nucleus as it transitions to a more stable state. This phenomenon is entirely independent of external factors like chemical bonding, temperature, or pressure, which primarily affect the electrons or the physical state of the atom rather than its core.

The hydrogen bomb, or thermonuclear bomb, is based on the principle of nuclear fusion. In this process, isotopes of hydrogen, such as deuterium and tritium, fuse together under extreme temperature and pressure to form helium nuclei, releasing an immense amount of energy. Although a nuclear fission reaction is used as a primary trigger to generate the necessary heat for the fusion process to begin, the defining principle and the source of the weapon's massive destructive power is fusion.

Explanation

The Singrauli Super Thermal Power Station is the first and oldest unit of NTPC. The foundation stone for this project was laid on February 11, 1977, and the first 200 MW unit was commissioned in February 1982. Geographically, the plant is located at Shaktinagar in the Sonbhadra district of Uttar Pradesh, not in Chhattisgarh. It is a pit-head power plant that draws water from the Rihand Reservoir and sources coal from the Jayant and Bina mines of the Singrauli coalfields, which are spread across the border of Uttar Pradesh and Madhya Pradesh.

Explanation

Diffusion of light in the atmosphere is primarily caused by the presence of suspended solid particles such as dust, smoke, and microscopic salt crystals. When solar radiation travels through the Earth's atmosphere, these particles intercept the incoming light rays and scatter them in multiple directions. This physical process, often referred to as Mie scattering or general diffusion, occurs because the size of dust particles is typically comparable to or larger than the wavelength of visible light. These particles are concentrated in the lower layers of the atmosphere and act as reflecting surfaces that distribute sunlight into shadowed areas, ensuring that the sky remains illuminated even when the sun is not directly overhead or is below the horizon during twilight.

Explanation

The Inter-state Council was established in 1990 following the recommendations of the Sarkaria Commission on Centre-State Relations, which was appointed by the Government of India in 1983. While Article 263 of the Constitution of India had always empowered the President to create such a body for coordination between the Union and the States, no permanent council was formed until the Sarkaria Commission strongly advocated for its creation to promote cooperative federalism. The commission, headed by Justice R.S. Sarkaria, suggested that the council should be a permanent body to discuss and investigate subjects of common interest. Acting on these recommendations, the President of India issued an order on May 28, 1990, officially constituting the Inter-state Council to strengthen the consultative process between different levels of government.

Explanation

Vitamin A is a fat-soluble vitamin found predominantly in animal products such as liver, milk, and eggs, or in plant sources rich in beta-carotene like carrots, sweet potatoes, spinach, and mangoes. While oranges are highly regarded for their Vitamin C content, they contain only negligible amounts of Vitamin A precursors. The primary nutritional contribution of citrus fruits like oranges is ascorbic acid, making the pairing of Vitamin A with orange inaccurate compared to established significant dietary sources of the vitamin.

Explanation

The Statue of Peace was inaugurated by Prime Minister Narendra Modi in November 2020 to mark the 151st birth anniversary of the Jain monk Acharya Shree Vijay Vallabh Surishwer Ji Maharaj. The 151-inch tall statue is crafted from Ashtadhatu, an alloy of eight metals, and is situated at the Vijay Vallabh Sadhana Kendra in Jaitpura, Pali district, Rajasthan. Acharya Vijay Vallabh was a revered saint who dedicated his life to the spread of education and social reforms while adhering to the principles of non-violence and peace.

Explanation

The Prime Minister Wi-Fi Access Network Interface (PM-VANI) scheme was approved by the Union Cabinet in December 2020 to promote the proliferation of broadband internet through public Wi-Fi networks across the country. The initiative aims to enhance digital connectivity and support the Digital India mission by allowing small shops and local establishments to become Public Data Offices (PDOs). These PDOs can provide high-speed internet access to users without requiring a license or paying registration fees. The framework includes Public Data Office Aggregators (PDOAs) and app providers to facilitate user authentication and service discovery. By leveraging a decentralized model, PM-VANI seeks to provide affordable and accessible internet connectivity to the masses, particularly in rural and underserved areas, thereby driving socio-economic growth through improved digital access.

Explanation

The Ecomark scheme was initiated by the Ministry of Environment and Forests in 1991 to label products that are environment-friendly. The certification is administered by the Bureau of Indian Standards (BIS) and is awarded to goods that meet specific ecological criteria alongside traditional quality standards. The symbol for the scheme is an earthen pot, which represents the use of natural resources and symbolizes the product's minimal impact on the environment during its lifecycle, including production, usage, and disposal. This initiative aims to increase consumer awareness regarding the environmental impact of products and encourages manufacturers to adopt greener production processes to ensure their goods are safe for the ecosystem.

Explanation

Fundamental Duties were incorporated into the Indian Constitution under Article 51A of Part IV-A by the 42nd Amendment Act, 1976, following the recommendations of the Swaran Singh Committee. While the committee had suggested that certain obligations like voting and paying taxes should be made duties of the citizens, the Parliament did not include them in the final list. Currently, there are eleven Fundamental Duties, and voting in general elections is not one of them. Instead, the right to vote is a constitutional right guaranteed under Article 326, which provides for adult suffrage, and it is also recognized as a statutory or legal right under the Representation of the People Act, 1951. Because it is missing from the specific list of duties enumerated in Article 51A, it is not classified as a Fundamental Duty.

Explanation

The Norwegian Nobel Committee awarded the 2020 Nobel Peace Prize to the World Food Programme (WFP) for its extensive efforts to combat hunger and its significant contribution to improving conditions for peace in conflict-affected areas. The organization was specifically lauded for acting as a driving force in international efforts to prevent the use of hunger as a weapon of war and conflict. As the largest humanitarian organization in the world addressing food security and hunger, the WFP provided aid to nearly 100 million people across 88 countries in the year preceding the award. The committee emphasized that achieving food security is a fundamental step toward ensuring global stability, as hunger and armed conflict often reinforce each other in a destructive cycle.

Explanation

Malik Sarwar, who held the title Khwaja-i-Jahan, was the founder of the independent Sharqi dynasty of the Jaunpur Sultanate. He was originally a prominent noble under Sultan Nasiruddin Mahmud Shah Tughlaq of the Delhi Sultanate, who appointed him as the Governor of the eastern provinces (Malik-ush-Sharq) in 1394 AD. During the period of political instability following Timur's invasion, he established his own independent rule with Jaunpur as its capital. The independent Sultanate of Malwa was actually founded by Dilawar Khan Ghori, who declared independence from the Delhi Sultanate in 1401 AD. Because Malik Sarwar is historically associated with Jaunpur rather than Malwa, this pairing is incorrect.

Explanation

World Tuberculosis Day is observed annually on March 24 to commemorate the date in 1882 when Dr. Robert Koch announced his discovery of Mycobacterium tuberculosis, the bacterium that causes the disease. For the year 2021, the World Health Organization selected The Clock is Ticking as the official theme. This theme was intended to communicate a sense of urgency, signaling that the world is running out of time to fulfill the global commitments made to end the tuberculosis epidemic. It emphasized the need to accelerate the response to TB to reach the targets set in the Sustainable Development Goals and the UN High-Level Meeting on TB, especially as the COVID-19 pandemic placed various tuberculosis elimination programs at risk.

Explanation

The 101st Constitutional Amendment Act, 2016, paved the way for the implementation of the Goods and Services Tax (GST) in India, which officially came into force on July 1, 2017. This landmark amendment introduced Article 246A, granting both the Union and State governments the concurrent power to legislate on goods and services tax. It also led to the insertion of Article 279A, which mandated the formation of the GST Council, chaired by the Union Finance Minister, to oversee the tax regime. By subsuming multiple indirect taxes like excise duty, service tax, and value-added tax into a single comprehensive levy, the act aimed to eliminate the cascading effect of taxation and establish a unified national market.

Explanation

Antony Blinken serves as the United States Secretary of State, a position equivalent to the Foreign Minister in many other government systems. Appointed by President Joe Biden, he visited New Delhi on July 27 and 28, 2021, to hold high-level talks with Indian officials, including Prime Minister Narendra Modi and External Affairs Minister S. Jaishankar. The visit was aimed at strengthening the India-US Comprehensive Global Strategic Partnership and discussing regional security issues, including the situation in Afghanistan and cooperation within the Quadrilateral Security Dialogue.

Explanation

The chronological sequence of these historical events begins with the Constitution of the Simon Commission (III) in November 1927, which was appointed by the British government to report on the functioning of the constitutional system in India. In response to the Simon Commission, the Nehru Report (II) was drafted in 1928 by a committee headed by Motilal Nehru to outline a proposed constitution for India. The Sharda Act (I), officially known as the Child Marriage Restraint Act, was enacted in 1929 to fix the minimum age for marriage. Subsequently, the Dandi March (IV) took place from March to April 1930, led by Mahatma Gandhi as an act of nonviolent protest against the British salt monopoly, marking the launch of the Civil Disobedience Movement. Based on the actual historical dates of 1927, 1928, 1929, and 1930, the sequence follows the order of III, II, I, and IV.

Explanation

Blue baby syndrome, clinically known as methemoglobinemia, is a condition characterized by a reduced ability of the blood to carry oxygen to body tissues. It occurs when hemoglobin, the oxygen-carrying protein in red blood cells, is converted into methemoglobin. In this state, the iron in the heme group is oxidized from the ferrous (Fe²⁺) state to the ferric (Fe³⁺) state. Unlike normal hemoglobin, methemoglobin cannot effectively bind or release oxygen. This condition is often triggered in infants when they ingest nitrates from contaminated well water, which are then converted to nitrites by bacteria in their digestive tract. These nitrites enter the bloodstream and oxidize hemoglobin into methemoglobin. As methemoglobin levels rise, the lack of oxygenated blood leads to cyanosis, manifesting as a bluish tint to the skin.

Explanation

Bottleneck inflation, also known as structural inflation, arises when the supply of goods and services is unable to keep pace with demand due to physical or institutional constraints rather than a general increase in the money supply. Assertion (A) is correct because this type of inflation is particularly difficult for the government and central bank to manage; traditional monetary policies like interest rate hikes are designed to curb demand but cannot easily fix underlying supply-side issues. Reason (R) provides the correct explanation for this difficulty by identifying the root causes as structural deficiencies. These include inadequate infrastructure, inefficient supply chains, logistical hurdles, and administrative delays that hinder the movement of goods from producers to consumers. Because resolving these bottlenecks requires long-term capital investment and systemic reforms rather than simple fiscal adjustments, the government faces a significant challenge in stabilizing prices.

Explanation

Lichens are symbiotic organisms consisting of a fungus and an alga that are highly sensitive to atmospheric chemistry. They function as natural bioindicators for air pollution, especially sulfur dioxide (SO₂), because they lack a protective cuticle and absorb moisture and nutrients directly from the air. This direct exposure ensures that airborne pollutants accumulate quickly within their tissues, inhibiting photosynthesis and growth. The absence or reduced diversity of lichen species in urban or industrial areas is a primary indicator of degraded air quality, while their presence and variety signal a clean environment.

Explanation

Haryana (IV) was established on November 1, 1966, after being separated from the state of Punjab based on the linguistic recommendations of the Shah Commission. Goa (I), which had been a Union Territory since its liberation from Portuguese rule in 1961, was granted full statehood on May 30, 1987, becoming the 25th state of the Indian Union. Jharkhand (III) was carved out of the southern districts of Bihar on November 15, 2000, under the Bihar Reorganisation Act, 2000. Telangana (II) was formed as the 29th state of India on June 2, 2014, through the Andhra Pradesh Reorganisation Act, 2014. The chronological sequence of their formation is IV (1966), I (1987), III (2000), and II (2014).

Explanation

Webb Miller was an American journalist and war correspondent for the United Press who provided the world with an eyewitness account of the Dharasana Satyagraha in May 1930. During this phase of the Civil Disobedience Movement, Miller witnessed and reported on the brutal police crackdown against non-violent protesters who were attempting to raid the Dharasana Salt Works. His graphic descriptions of peaceful satyagrahis being beaten systematically by the police without retaliating were published in over a thousand newspapers globally. These reports played a critical role in turning international public opinion against British colonial policy and highlighting the moral strength of the Indian independence movement led by Mahatma Gandhi.

Explanation

World Ozone Day, officially known as the International Day for the Preservation of the Ozone Layer, is observed every year on 16th September. This date was chosen by the United Nations General Assembly in 1994 to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer, which occurred on September 16, 1987. The primary objective of this day is to spread awareness about the depletion of the ozone layer and to encourage global efforts to protect it by phase-outing the production and consumption of ozone-depleting substances. The Montreal Protocol is widely considered one of the most successful environmental treaties, as it has led to the gradual recovery of the ozone layer.

Explanation

Urbanization contributes to a decrease in the birth rate due to several socio-economic factors. In urban environments, the cost of raising children is higher, living spaces are often smaller, and children are viewed more as economic responsibilities rather than additional hands for agricultural labor. Furthermore, urban areas offer better access to healthcare facilities, reproductive education, and family planning services, which facilitate smaller family sizes.

Literacy is a fundamental determinant of demographic transition. A high literacy rate, particularly among women, leads to increased awareness of contraception and reproductive rights. Education often results in the delay of marriage and first pregnancy, which naturally shortens the total fertility period of an individual. Additionally, literate populations tend to have higher economic aspirations and better employment opportunities, leading to a conscious preference for fewer children to ensure better investments in health and education for the next generation.

Explanation

The Uttar Pradesh Population Control, Stabilisation and Welfare Bill, 2021, along with the state's Population Policy 2021-2030, aims to lower the Total Fertility Rate (TFR) to 2.1 by 2026 and further to 1.9 by 2030. At the time of the policy's introduction, the fertility rate in Uttar Pradesh was recorded at 2.7. The bill proposes various incentives for individuals who adhere to the two-child norm and seeks to promote population stabilization to ensure sustainable development and better distribution of resources across the state.

Explanation

The provision of Residuary Powers, which stipulates that the power to legislate on any matter not enumerated in the Concurrent List or State List vests in the Union Parliament, is borrowed from the Canadian Constitution. In contrast, the Australian Constitution influenced the Indian Constitution regarding the Concurrent List, the freedom of trade, commerce and intercourse, and the provision for the joint sitting of the two Houses of Parliament. Under Article 248 of the Indian Constitution, the residuary powers of legislation belong to the Union, aligning with the Canadian federal model rather than the Australian one.

Explanation

The 47th G7 summit was held from June 11 to 13, 2021, in Carbis Bay, Cornwall, with the United Kingdom serving as the host and holding the presidency. Consequently, the Prime Minister of the United Kingdom chaired the meetings. For the 2021 summit, the UK invited leaders from Australia, India, South Korea, and South Africa to participate as guest countries to broaden the discussion on global issues such as pandemic recovery and climate change. Brazil was not included in the list of guest nations for this specific summit.

Explanation

The Public Accounts Committee is a parliamentary standing committee tasked with examining the audit reports of the Comptroller and Auditor General of India. These reports, which are laid before Parliament by the President, include audit findings on appropriation accounts and finance accounts of the Union Government. The committee ensures that public money is spent legally and for the specific purposes authorized by Parliament. It investigates cases of waste, loss, corruption, or inefficiency in the execution of government policies and programs. During this process, the Comptroller and Auditor General assists the committee by acting as its guide, philosopher, and friend, helping the members interpret technical audit findings and examine witnesses from various ministries.

Explanation

The urbanization curve, typically represented as an S-shaped model, describes the process of urban growth over time. The second stage is identified as the acceleration stage because it corresponds with the period of rapid industrialization and economic development. During this phase, there is a massive shift of the population from rural to urban areas driven by the availability of jobs in the manufacturing and service sectors. As infrastructure improves and the demand for labor in cities increases, the rate of urbanization rises sharply, leading to a steep upward slope in the curve. This stage marks the transition from a primarily agrarian society to an industrial one, resulting in the fastest growth of the urban population percentage compared to other phases of the curve.

Explanation

Maharaja Ranjit Singh established the Adalat-i-Ala, or the High Court, at Lahore, which served as the capital of the Sikh Empire. This central judicial body was the highest court in the state, handling significant civil and criminal cases and serving as an appellate authority for decisions made by local officials such as Kardars and Nazims. Since Lahore was the administrative heart of the Sarkar-i-Khalsa, the Adalat-i-Ala was positioned there to ensure that the Maharaja's central administration could oversee the delivery of justice and maintain legal order throughout the various provinces of the empire.

Explanation

Socotra is an archipelago located in the Indian Ocean, situated between the Guardafui Channel and the Arabian Sea. Politically, it is a territory of Yemen and is governed as the Socotra Governorate. The island is famous for its unique biodiversity and extreme endemism, with approximately 37 percent of its plant species and 90 percent of its reptile species found nowhere else on Earth. Recognizing its global importance for conservation and its exceptional natural beauty, UNESCO inscribed the Socotra Archipelago as a World Natural Heritage site in 2008.

Explanation

The Uttar Pradesh Mukhya Mantri Yuva Swarojgar Yojna is a state-level initiative designed specifically to provide self-employment opportunities and financial assistance to the educated unemployed youth residing within the state. A fundamental eligibility requirement for this scheme is that the applicant must be a permanent resident or domicile of Uttar Pradesh. Consequently, the scheme is not open to citizens from any state of India; it is restricted to those who can provide proof of residence in Uttar Pradesh. This residency restriction ensures that the state government's budgetary allocations for entrepreneurship and job creation directly benefit the local population and the state's internal economy.

Explanation

Under Article 109 of the Constitution of India, a Money Bill shall not be introduced in the Council of States (Rajya Sabha). According to the constitutional procedure, a Money Bill, which is defined under Article 110, can only be introduced in the House of the People (Lok Sabha) and only on the recommendation of the President. After the Lok Sabha passes a Money Bill, it is transmitted to the Rajya Sabha for its recommendations. The Rajya Sabha must return the Bill to the Lok Sabha within a period of fourteen days from the date of its receipt. The Lok Sabha has the discretion to either accept or reject any or all of the recommendations made by the Rajya Sabha. If the Rajya Sabha fails to return the Bill within the stipulated fourteen-day period, the Bill is deemed to have been passed by both Houses in the form in which it was originally passed by the Lok Sabha.

Explanation

Zero Hour is an informal procedural device in the Indian Parliament that allows members to raise matters of urgent public importance without prior notice. It is an Indian innovation in the field of parliamentary procedures and has been in existence since 1962. This period starts immediately after the Question Hour concludes and lasts until the regular listed business of the day is taken up. Because it typically begins at 12:00 noon, it is colloquially termed as the Zero Hour. Unlike Question Hour, Zero Hour is not mentioned in the Rules of Procedure and remains an informal mechanism for members to seek immediate government attention on pressing issues.

Explanation

A distinguished economist, she previously served as the first female Chair of the Federal Reserve from 2014 to 2018 and led the Council of Economic Advisers from 1997 to 1999. Her appointment made her the first person in American history to have headed the three most powerful economic institutions in the federal government. As Treasury Secretary, she is responsible for advising the President on economic and financial issues, overseeing the nation's revenue collection, and managing the public debt.

Explanation

The chronological sequence of these landmark legal events in Indian constitutional history is determined by their actual years of occurrence. The Golak Nath Case took place in 1967, where the Supreme Court ruled that Parliament could not take away any Fundamental Rights. In response to this judgment, the 24th Constitution Amendment Act was enacted in 1971 to restore and assert the power of Parliament to amend any part of the Constitution. This amendment was subsequently challenged in the Keshavananda Bharati Case of 1973, which resulted in the formulation of the Basic Structure doctrine. Finally, the 42nd Constitution Amendment Act was passed in 1976 during the Emergency to significantly alter various provisions of the Constitution. Therefore, the correct chronological order is Golak Nath Case (1967), 24th Amendment (1971), Keshavananda Bharati Case (1973), and 42nd Amendment (1976).

Explanation

The New York Times was awarded the 2021 Pulitzer Prize in the Public Service category for its extensive and courageous coverage of the COVID-19 pandemic. The Pulitzer Board recognized the newspaper for providing prescient and sweeping reporting that exposed racial and economic inequities in the healthcare system and documented government failures in the United States and abroad.

Explanation

Chilika Lake, situated in Odisha, is recognized as the largest brackish water lagoon in India and the second largest coastal lagoon in the world. It spreads over the Puri, Khurda, and Ganjam districts on the east coast of India at the mouth of the Daya River, which flows into the Bay of Bengal. The lake covers an area of approximately 1,100 square kilometers during the monsoon season. In 1981, it was designated as the first Indian wetland of international importance under the Ramsar Convention due to its rich biodiversity, including being a massive wintering ground for migratory birds and a habitat for the endangered Irrawaddy dolphin. Its unique estuarine character, maintained by the constant inflow of freshwater from rivers and saltwater from the sea, makes it the preeminent lagoon formation on the Indian eastern seaboard.

Explanation

This annual maritime exercise is sponsored by the U.S. Africa Command and led by U.S. Naval Forces Africa, focusing on regional cooperation and maritime security. During the 2021 edition, the Indian Navy ship took part in training exercises focused on maritime law enforcement, information sharing, and search and rescue operations. INS Talwar’s participation aimed at strengthening the maritime bond with East African nations and other international partners to ensure a safe and secure Western Indian Ocean region.

Explanation

Respiration is a metabolic process where harvested fruits consume oxygen to break down stored organic substrates like sugars into carbon dioxide, water, and energy. This physiological process is directly linked to the ripening, aging, and eventual decay of the fruit. The rate of these biochemical reactions is highly sensitive to temperature; lowering the temperature in a cold chamber reduces the kinetic energy of the molecules and suppresses the activity of respiratory enzymes. By significantly decreasing the rate of respiration, the fruit's metabolic activity slows down, its internal energy reserves are conserved, and the production of ripening hormones like ethylene is inhibited. This reduction in metabolic velocity effectively delays senescence, thereby extending the storage life and preserving the freshness of the produce.

Explanation

Carbohydrates are organic compounds fundamentally composed of three elements: carbon (C), hydrogen (H), and oxygen (O). Their name is derived from the fact that they are essentially hydrates of carbon, often represented by the general empirical formula Cₙ(H₂O)ₘ. Simple sugars like glucose (C₆H₁₂O₆) and complex polysaccharides like starch and cellulose are built entirely from these three atoms. Their molecular structure consists of carbon chains with attached hydroxyl groups and either an aldehyde or a ketone functional group. Because the core chemical identity of carbohydrates is defined by this specific elemental combination, nitrogen is not a constituent part of their basic structure.

Explanation

The Preamble of the Indian Constitution declares India to be a Sovereign, Socialist, Secular, Democratic, Republic. It outlines the objectives of securing justice, liberty, equality, and fraternity for its citizens. The word Federal is not mentioned in the Preamble, nor does it appear anywhere in the actual text of the Constitution of India. Instead, Article 1 of the Constitution describes India as a Union of States. While the Indian political system incorporates federal features such as a dual polity and division of powers, the framers specifically omitted the term Federal from the Preamble to emphasize the indestructible nature of the Indian Union.

Explanation

Amir Hasan Sijzi, a renowned poet and devoted disciple of the Sufi saint Shaikh Nizamuddin Auliya, compiled the Fawaid ul Fawaid. This work is a primary source of malfuzat literature, which records the oral teachings and conversations of the saint over a period of fifteen years, specifically from 1307 to 1322. By documenting these spiritual discourses, Sijzi preserved the ethical teachings, mystical insights, and social history of the Chishti order during the Delhi Sultanate. The text is celebrated for its simplicity and for providing a vivid account of the spiritual environment surrounding the Khanqah of Shaikh Nizamuddin Auliya.

Explanation

The Environment (Protection) Act was enacted by the Parliament of India in 1986 under Article 253 of the Constitution. This legislation was primarily motivated by the Bhopal Gas Tragedy of 1984, which highlighted the need for a comprehensive law to address environmental safety and industrial disasters. It functions as umbrella legislation that empowers the Central Government to coordinate the activities of various state and central authorities and to establish environmental quality standards. The Act also serves to implement the decisions taken at the United Nations Conference on the Human Environment held in Stockholm in 1972, focusing on the protection and improvement of the environment and the prevention of hazards to human beings, other living creatures, plants, and property.

Explanation

Technocrats and bureaucrats represent the administrative and institutional framework of a state rather than the core economic determinants of growth. In standard economic theory, growth is driven by the expansion of productive capacity through factors like capital formation, technological progress, and labor force dynamics. While administrative officials are responsible for the implementation of policy and maintaining the legal framework, they are considered human agents of governance rather than fundamental economic inputs. They do not constitute a primary factor of production or a direct driver of productivity in the same way that capital investment, technological innovation, and the scaling of labor through specialization do. Consequently, they are classified as institutional variables rather than major factors of economic growth.

Explanation

The Ringelmann scale is a standard method used to measure the apparent density or opacity of smoke emitted from stationary sources like industrial chimneys and stacks. Developed by French professor Maximilian Ringelmann in 1888, the scale consists of a series of cards with varying shades of gray produced by black grid lines on a white background. An observer compares the shade of the smoke against these cards, which range from Ringelmann 0 (0 percent opacity or white) to Ringelmann 5 (100 percent opacity or solid black), with intermediate levels representing 20, 40, 60, and 80 percent density. This system allows for a visual assessment of particulate matter concentrations in emissions to monitor and enforce air pollution control regulations.

Explanation

The Vaikom Satyagraha, conducted from 1924 to 1925 in the princely state of Travancore, was a landmark movement directed against untouchability and the rigid caste hierarchy. The primary objective was to secure the rights of lower-caste individuals, such as the Ezhavas and Pulayas, to walk on the public roads leading to the Vaikom Mahadeva Temple, which were then restricted to upper castes. Mahatma Gandhi played a significant role in this movement by providing strategic guidance and personal participation. He visited Vaikom in March 1925, where he interacted with the satyagrahis, addressed public meetings, and negotiated with the Maharani Regent and the orthodox Brahmin leadership. His intervention was pivotal in transforming the local protest into a national issue and facilitating the eventual compromise that opened the roads to all sections of society.

Explanation

Auguste Comte, the founder of sociology, formulated the Law of Three Stages in his work Cours de Philosophie Positive. This theory posits that human intellect and society evolve through three distinct chronological phases. The first is the Theological stage, where phenomena are attributed to the actions of supernatural beings or gods. The second is the Metaphysical stage, a transitional period where abstract forces, essences, or personified entities replace deities. The final stage is the Positive or Scientific stage, where human thought relies on empirical observation, reasoning, and the establishment of scientific laws to understand the world. Comte argued that this progression is universal and represents the evolution of the human mind and social organization toward a rational and scientific order.

Explanation

Neutrinos are subatomic particles that belong to the lepton family and are characterized by having zero electrical charge. Because they carry no charge, they are immune to electromagnetic interactions and only interact with other particles via gravity and the weak nuclear force. This neutrality allows them to travel through dense matter, including planets and stars, with extremely low probability of collision. Neutrinos are emitted in vast numbers during stellar nucleosynthesis and certain types of radioactive decay, such as beta decay, where they carry away energy while maintaining the conservation of lepton number and charge.

Explanation

Ngozi Okonjo-Iweala is a Nigerian-American economist who made history in February 2021 when she was appointed as the seventh Director-General of the World Trade Organization. This appointment made her both the first woman and the first African to lead the global trade body. Before taking on this international role, she had a distinguished career in her home country of Nigeria, where she served two terms as the Finance Minister and also held the position of Foreign Minister. Her professional background also includes a 25-year career at the World Bank, where she eventually rose to the rank of Managing Director of Operations.

Explanation

The Central Agro-Forestry Research Institute (CAFRI) is located in Jhansi, Uttar Pradesh, rather than Banda. It was originally established in 1988 as the National Research Centre for Agroforestry under the Indian Council of Agricultural Research (ICAR) and was later upgraded to a full research institute in 2014. The institute is dedicated to improving land-use systems and developing sustainable agroforestry technologies for various agro-climatic conditions, with its primary headquarters and research farm situated in Jhansi.

Explanation

The book Poverty and Un-British Rule in India was written by Dadabhai Naoroji and published in 1901. In this influential work, Naoroji articulated his Drain of Wealth theory, which explained how India's resources were being systematically transferred to Britain. He argued that this continuous drain, consisting of home charges, interest payments, and profits sent abroad, was the primary cause of India's extreme poverty and the frequent famines during the colonial period. By using statistical data to support his arguments, Naoroji provided the early Indian nationalist movement with a solid economic critique of British imperialism.

Explanation

The First Finance Commission of India was established by the President in 1951 under Article 280 of the Constitution. Kshitish Chandra Neogy, popularly known as K. C. Neogy, was appointed as the Chairman of this commission. The primary objective of the commission was to provide a framework for the distribution of tax revenues between the Union and the States and to determine the principles for granting financial assistance to the states. The commission submitted its report in 1952, and its recommendations were implemented for the period of 1952 to 1957.

Explanation

Osmosis is the spontaneous movement of water molecules from a region of higher water concentration to a region of lower water concentration through a semi-permeable membrane. When salt is added to a cut cucumber, it creates a hypertonic environment on the surface, meaning the salt concentration outside the cells is much higher than inside. The cell membranes of the cucumber act as semi-permeable barriers, allowing water to pass through while restricting larger solute particles. Consequently, water moves out of the cucumber cells to dilute the salt on the surface in an attempt to reach equilibrium. This specific movement of water out of the cells is referred to as exosmosis.

Explanation

Surinsar-Mansar Lakes is a Ramsar wetland site located in the Jammu district of the Union Territory of Jammu and Kashmir. It was designated as a wetland of international importance in November 2005. The site comprises two separate freshwater lakes, Surinsar and Mansar, situated in the semi-arid Himalayan foothills. These lakes are culturally significant and support a diverse range of biodiversity, including the rare freshwater turtle Lissemys punctata and various species of migratory birds. Since the site is located in the northernmost region of India within Jammu and Kashmir, it does not fall under the jurisdiction or geographical territory of Uttar Pradesh.

Explanation

The alveoli are the terminal, thin-walled, and highly vascularized air sacs within the lungs where the actual exchange of gases occurs. These structures provide a massive surface area, which is essential for efficient respiration in mammals. Each alveolus is surrounded by a network of pulmonary capillaries, and the barrier between the air and the blood consists of only two thin layers of cells: the alveolar epithelium and the capillary endothelium. This arrangement allows oxygen to diffuse rapidly from the inhaled air into the bloodstream and carbon dioxide to move from the deoxygenated blood into the alveoli to be exhaled. The process is governed by the partial pressure gradients of these gases across the respiratory membrane.

Explanation

Cultural diversity is a defining characteristic of urban communities rather than rural ones. Rural communities are typically marked by cultural homogeneity, where members share similar values, traditions, and ways of life due to less exposure to outside influences and lower rates of migration. In contrast, urban areas act as melting pots that bring together people from various ethnic, linguistic, and cultural backgrounds, resulting in the heterogeneity that defines cultural diversity. Social life in a rural setting is built on commonalities and long-standing shared practices that reinforce a unified social structure.

Explanation

Tapa cloth, a traditional bark cloth, is produced from the inner bark (bast) of trees primarily belonging to the Moraceae family. The most common source is the paper mulberry tree (Broussonetia papyrifera), though other members of this family, such as breadfruit (Artocarpus altilis) and various species of fig (Ficus), are also used. The production process involves stripping the inner bark from the tree, soaking it to soften the fibers, and then beating it with wooden mallets on an anvil. This mechanical action causes the fibers to felt and expand into a wide, flexible sheet. The Moraceae family is specifically valued for this purpose because its bast fibers possess the necessary length and strength to form a cohesive, durable textile without the need for weaving.

Explanation

The Indian Council Act of 1861 formally recognized the portfolio system, which had been introduced on an informal basis by Lord Canning in 1859. This Act empowered the Viceroy to make rules and orders for the more convenient transaction of business in the council. Under this system, individual members of the Viceroy's Executive Council were placed in charge of one or more departments of the government. Each member was authorized to issue final orders on behalf of the council regarding matters related to their specific department. This transition from collective or corporate functioning to a departmental system streamlined the administration and significantly strengthened the executive authority of the Viceroy over his council.

Explanation

An ecosystem is defined as a functional unit where biotic components like plants, animals, and microorganisms interact with each other and with their abiotic environment, including soil, water, and sunlight. This interdependence is fundamental for energy flow and nutrient cycling, making the assertion that these components are not interdependent scientifically incorrect. Conversely, the reason provided is a well-established fact. Human activities, ranging from industrialization and urbanization to agriculture and deforestation, exert significant pressure on the environment, leading to global phenomena such as climate change, pollution, and the loss of biodiversity. These anthropogenic impacts demonstrate the profound effect human society has on ecological systems and the broader environment.

Explanation

The Uttar Pradesh Budget for 2021-22 introduced several new welfare initiatives targeted at various sectors. The Atmanirbhar Krishak Samanvit Vikas Yojna was launched with an initial allocation of 100 crore to increase farmer income and promote Farmer Producer Organizations (FPOs). The Mukhya Mantri Saksham Suposhan Yojna was established to combat malnutrition among children and anemia in women by providing specialized nutritional support. The Mukhya Mantri Pravasi Shramik Udyamita Vikas Yojna was announced to provide livelihood opportunities and self-employment to migrant laborers who returned to Uttar Pradesh during the COVID-19 pandemic. These specific schemes were part of the new proposals within the 2021-22 financial statement.

Explanation

The souring of milk is a biological process caused by the fermentation of lactose, a disaccharide sugar found in milk, by lactic acid bacteria such as Lactobacillus. These bacteria convert lactose into lactic acid (C₃H₆O₃), which increases the acidity of the milk, leads to the denaturation of proteins like casein, and produces the characteristic sour taste. Nitric acid (HNO₃) is a strong, highly corrosive mineral acid typically used in the production of fertilizers and explosives; it is not naturally present in milk nor is it a product of milk spoilage or fermentation.

Explanation

Mount Rainier is a massive stratovolcano located in the Cascade Range of Washington state in the U.S.A. Mount Etna is situated on the east coast of Sicily, Italy, and is recognized as one of the most active volcanoes in the world. Mount Paricutin is a cinder cone volcano found in the state of Michoacán, Mexico, notable for its well-documented birth and growth beginning in 1943. Mount Apo is a potentially active stratovolcano located on the island of Mindanao and holds the distinction of being the highest mountain in the Philippines.

Explanation

Liquefied Petroleum Gas (LPG) is a flammable mixture of hydrocarbon gases used as fuel in heating appliances, cooking equipment, and vehicles. It primarily consists of propane and butane, with butane being the predominant component in the mixture. Domestic LPG cylinders typically contain a higher proportion of n-butane and iso-butane because these gases are easily liquefied under moderate pressure for storage and transport. The chemical formula for butane is C₄H₁₀. Although it is naturally odorless, a pungent-smelling chemical called ethyl mercaptan is added to LPG to help detect any leakages.

Explanation

The Jonk river is a significant tributary of the Mahanadi river system, rather than the Ganga. It originates from the Sunabeda plateau in the Nuapada district of Odisha and flows through the Mahasamund and Raipur districts of Chhattisgarh. The river travels for approximately 210 kilometers before joining the Mahanadi river at Seorinarayan. Because the Mahanadi is an independent river system that drains the central Indian plateau and empties directly into the Bay of Bengal, its tributaries are geographically and hydrologically distinct from the Ganga river basin.

Explanation

Blood glucose level refers to the concentration of glucose present in the blood of humans and other animals. In clinical diagnostics and medical reporting, this concentration is most commonly expressed in milligrams per decilitre (mg/dL). A decilitre (dL) is a unit of volume equivalent to one-tenth of a litre or 100 millilitres. Therefore, the measurement represents the mass of glucose in milligrams found in 100 millilitres of blood. For a healthy individual, a normal fasting blood sugar level is typically expected to be between 70 and 99 mg/dL. This standardized unit is essential for monitoring metabolic health and diagnosing conditions such as diabetes and hypoglycemia.

Explanation

The Saras Ajeevika Mela 2021 was held at Noida Haat, Sector 33A, Noida, from February 26 to March 14, 2021. It was inaugurated by the Union Minister for Rural Development and is an initiative under the Ministry of Rural Development as part of the Deendayal Antyodaya Yojana-National Rural Livelihoods Mission (DAY-NRLM). The event serves as a platform to bring rural women Self-Help Groups (SHGs) together to showcase their skills and sell their diverse products, ranging from handlooms and handicrafts to organic food, directly to urban consumers. The mela aims to empower rural women by eliminating middlemen and creating direct market linkages for their sustainable livelihood.

Explanation

The Kanto Plain is the largest plain in Japan, situated on the island of Honshu and bordering the Pacific Ocean. It serves as the country's most significant agricultural and industrial region, housing the Greater Tokyo Area. The Nobi Plain is another major alluvial plain located in central Honshu, surrounding the city of Nagoya. It is formed by the Kiso, Ibi, and Nagara rivers and is one of the most densely populated and productive regions in Japan. Both plains are essential geographical features of the Japanese archipelago.

Explanation

The India Climate Change Knowledge Portal was launched on November 27, 2020, by the Union Minister of Environment, Forest and Climate Change. It was established as a comprehensive one-stop solution to provide information on various climate initiatives taken by the Government of India at both national and international levels. The portal captures major steps regarding India's climate actions, including sector-wise adaptation and mitigation measures, international commitments like the Nationally Determined Contributions under the Paris Agreement, and various stakeholder engagements. By disseminating updated data and progress reports, it serves as a transparent repository for citizens and researchers to understand the country's transition toward a low-carbon economy.

Explanation

Shaheed Ram Prasad Bismil was born on June 11, 1897, in Shahjahanpur, Uttar Pradesh. To commemorate his 124th birth anniversary as part of the Azadi Ka Amrit Mahotsav celebrations, the Ministry of Culture, Government of India, organized a special event in Shahjahanpur in June 2021. This celebration was designed to honor the revolutionary spirit of Bismil, who was a founding member of the Hindustan Republican Association and a key figure in the Kakori Train Action of 1925. The event served to highlight his contributions as both a fearless freedom fighter and a prolific writer and poet, whose works like Sarfaroshi Ki Tamanna inspired generations of Indian nationalists.

Explanation

Sir William Jones, a renowned philologist and judge of the Supreme Court of Judicature at Fort William, founded the Asiatic Society on January 15, 1784. The institution was established in Calcutta to foster and facilitate Oriental research, focusing specifically on the history, antiquities, arts, sciences, and literatures of Asia. Jones served as its first president and envisioned the society as a platform for systematic study of the Indian subcontinent's heritage. His efforts led to the translation of numerous classical Sanskrit texts into English, significantly contributing to the Western understanding of Indian culture and history during the late eighteenth century.

Explanation

Net-zero emissions, also referred to as carbon neutrality, describes a balance where the total amount of greenhouse gases released into the atmosphere is offset by an equivalent amount being removed. This concept does not imply that a country must reduce its gross emissions to absolute zero, which is often technically or economically unfeasible for certain industrial and agricultural sectors. Instead, any residual emissions produced are compensated for through carbon sequestration. This compensation occurs via natural carbon sinks, such as massive reforestation and soil restoration projects, or through engineered solutions like Carbon Capture and Storage (CCS) and Direct Air Capture (DAC) technologies. The goal is to ensure that the net contribution of greenhouse gases to the atmosphere remains at zero.

Explanation

Article 75(3) of the Constitution of India explicitly states that the Council of Ministers shall be collectively responsible to the House of the People, which is the Lok Sabha. This collective responsibility is a fundamental principle of the parliamentary system, ensuring that the executive remains accountable to the directly elected chamber. There is no constitutional provision for the Council of Ministers to be collectively responsible to the Rajya Sabha.

Under Article 75(5) and established constitutional practice, any person appointed as a Minister must be a member of either the Lok Sabha or the Rajya Sabha. If a person who is not a member of either House is appointed as a Minister, they must secure a seat in either House within a period of six consecutive months to continue in office. Therefore, membership in either House of Parliament is a valid qualification for holding a ministerial position in the Union Government.

Explanation

The Agriculture Infrastructure and Development Cess (AIDC) was proposed in the Union Budget 2021-22 to generate dedicated resources for improving agricultural infrastructure and enhancing production across the country. This levy is applied to a total of 29 products. The breakdown of these products includes 25 items on the customs side and 4 items on the excise side. The 25 customs-linked items comprise imported commodities such as gold, silver, alcoholic beverages, crude palm oil, crude soybean oil, apples, peas, lentils, and cotton. The 4 excise-linked products consist of unbranded petrol, branded petrol, unbranded high-speed diesel, and branded high-speed diesel. The government ensured that the introduction of this cess did not increase the overall tax burden on consumers by simultaneously reducing the Basic Customs Duty and the Basic Excise Duty on these specific goods.

Explanation

Under Article 317 of the Constitution of India, the Chairman or any member of a State Public Service Commission can only be removed from office by the President. Although the Governor appoints these members, the power of removal is exclusively vested in the President to ensure the independence and impartiality of the Commission. For removal on the grounds of misbehaviour, the President is required to refer the case to the Supreme Court for an inquiry. This inquiry follows the procedure laid down under Article 145 of the Constitution. If the Supreme Court, after due investigation, upholds the charges and recommends removal, the President issues the order accordingly. The advice tendered by the Supreme Court in such matters is binding on the President. While the inquiry is pending, the Governor possesses the authority to suspend the concerned member, but the final authority for removal remains with the President.

Explanation

Syria is a West Asian country located on the eastern coast of the Mediterranean Sea. Its geographic position is south of the Anatolian peninsula, which places the entire landmass of Turkey between Syria and the Black Sea. Consequently, Syria has no maritime border or coastline adjacent to the Black Sea waters.

Explanation

Ralph Fitch was an English merchant who traveled to India during the reign of Akbar, visiting places like Agra and Fatehpur Sikri between 1583 and 1591. William Hawkins arrived at the port of Surat in 1608 on the ship Hector and visited the court of Emperor Jahangir to seek trade concessions. Nicholas Dawnton arrived in India in 1614 as a commander for the East India Company and is noted for leading the English fleet to victory over the Portuguese at the Battle of Swally. Sir Thomas Roe arrived at Jahangir court as the official ambassador of King James I in September 1615, staying until 1619 to secure formal commercial privileges for the British. This establishes the chronological order as Ralph Fitch, William Hawkins, Nicholas Dawnton, and Sir Thomas Roe.

Explanation

Capital formation refers to the net addition to the stock of physical assets such as machinery, equipment, buildings, and infrastructure within an economy over a period. Statement 1 is correct because capital formation is a multi-stage process that begins with the creation of savings. The volume of savings determines the pool of resources available for investment. Furthermore, the effectiveness of financial institutions, including banks and capital markets, is crucial for mobilizing these scattered savings and channeling them into productive sectors.

Statement 2 is correct because investment is the functional mechanism of capital formation. While savings represent a withdrawal from current consumption, investment is the act of using those saved resources to produce capital goods. Without the conversion of financial resources into real productive assets through investment, capital formation cannot occur. Thus, both the availability of savings through financial intermediation and the subsequent investment of those funds are indispensable components of the capital formation process.

Explanation

Ambika Chakravarti was a prominent revolutionary leader based in Bengal and was a key figure in the Chittagong group led by Surya Sen. He is best known for his central role in the Chittagong Armoury Raid of 1930 and his membership in the Indian Republican Army. The Naujawan Bharat Sabha was established in March 1926 in Lahore, Punjab, as a militant youth organization aimed at mobilizing students and laborers against British rule while promoting secularism. Because Ambika Chakravarti's political and revolutionary activities were geographically and organizationally centered in the Bengal Presidency, he was not involved in the early membership or activities of the Punjab-based Naujawan Bharat Sabha.

Explanation

Indonesia is an archipelagic nation where the major islands follow a distinct longitudinal progression from west to east along the Sunda Arc. Sumatra is the westernmost major island, situated closest to the Malay Peninsula and separated from it by the Strait of Malacca. Moving eastward across the Sunda Strait lies Java, the administrative and economic heart of the country. Continuing further east across the narrow Bali Strait is the island of Bali. East of Bali, separated by the deep Lombok Strait which serves as the biogeographic boundary known as the Wallace Line, is the island of Lombok. This sequence aligns with the geological formation of the Lesser Sunda Islands stretching toward the Banda Sea.

Explanation

The first Municipal Corporation in India was established in Madras in 1688. It was created following a Royal Charter issued by King James II of England on December 30, 1687, acting on the advice of the East India Company's Court of Directors. The corporation was officially inaugurated on September 29, 1688, to manage the civic affairs of the settlement, including local taxation and urban administration. This institution served as the precursor to the modern system of urban local bodies in India.

It was officially established as a separate district in September 2011 after being carved out of the Ghaziabad district. Since its creation, Hapur has consistently ranked as the smallest administrative unit among all 75 districts of Uttar Pradesh, a fact reflected in the official land records and demographic data available up to 2021.

Explanation

Dr. Christiaan Barnard performed the first human-to-human heart transplant on December 3, 1967, at Groote Schuur Hospital in Cape Town, South Africa. The procedure involved transplanting the heart of a donor, Denise Darvall, into a 53-year-old patient named Louis Washkansky who was suffering from chronic heart failure. This pioneering surgery lasted approximately nine hours and utilized a medical team of thirty people. While the patient lived for only 18 days before succumbing to pneumonia resulting from the immunosuppressive drugs used to prevent organ rejection, the operation remains a milestone in medical history for demonstrating the technical viability of heart replacement surgery.

Explanation

The Mekong River originates in the Sanjiangyuan area of the Tibetan Plateau in China, where it is known as the Lancang River. It is the longest river in Southeast Asia, flowing through six countries: China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. The Mekong Delta is located in southern Vietnam, where the river empties into the South China Sea through a vast network of distributaries. While the river passes through Cambodia and creates significant floodplains near Phnom Penh, the geographical region defined as the Mekong Delta begins after the river crosses the border into Vietnam.

Explanation

Retinol is a fat-soluble form of Vitamin A that plays a fundamental role in the visual cycle. Within the retina, retinol is converted into retinal, which combines with the protein opsin to form rhodopsin, the primary light-sensitive pigment in rod cells. Rhodopsin is essential for detecting light in low-intensity conditions, enabling night vision. Additionally, Vitamin A is necessary for maintaining the health of the cornea and conjunctival membranes, ensuring the overall structural integrity of the eye. A deficiency in retinol typically manifests as night blindness or xerophthalmia.

Explanation

Sardar Vallabhbhai Patel made this statement during the Constituent Assembly debates on August 27, 1947. As the Chairman of the Advisory Committee on Fundamental Rights, Minorities and Tribal and Excluded Areas, Patel was a firm critic of the system of separate electorates. He argued that separate electorates were a legacy of the British policy of divide and rule, which had fostered communalism and ultimately led to the partition of India. Patel believed that continuing such a system in an independent nation would be suicidal for minorities, as it would isolate them from the mainstream political process and hinder national integration. He challenged the assembly to find any other free, democratic country that maintained communal electorates, asserting that the mischief created by the British must be eradicated to build a unified Indian state.

Explanation

According to the 15th edition of the Global Peace Index (GPI) released by the Institute for Economics and Peace (IEP) in 2021, Europe was ranked as the most peaceful region in the world. This region has maintained this top position every year since the index began. In the 2021 report, Europe accounted for eight of the ten most peaceful countries globally, benefiting from high levels of socio-economic development, low levels of internal conflict, and robust political stability. The index evaluates peace across three primary domains: the level of societal safety and security, the extent of ongoing domestic and international conflict, and the degree of militarisation. Europe consistently performs well across all these indicators compared to other geographical regions.

Explanation

Assertion (A) is false because the human body cannot synthesize most of the vitamins it requires for survival and must obtain them through dietary sources. While the body can produce Vitamin D through exposure to sunlight and Vitamin K through bacteria in the intestinal tract, it lacks the biological mechanisms to produce other essential vitamins like Vitamin C and the various B-complex vitamins. Reason (R) is true as vitamins are organic micronutrients that play critical roles in metabolic processes, immune function, and cell repair, making them indispensable for the healthy development and proper growth of the human body.

Explanation

Sugamya Bharat Abhiyan, also known as the Accessible India Campaign, was launched by the Government of India on December 3, 2015, to coincide with the International Day of Persons with Disabilities. It is a nation-wide flagship campaign spearheaded by the Department of Empowerment of Persons with Disabilities (DEPwD) under the Ministry of Social Justice and Empowerment. The primary goal of the scheme is to ensure universal accessibility for Persons with Disabilities (Divyangjan) so they can live independently and participate fully in all aspects of life. The campaign focuses on three main pillars: making the built environment accessible through ramps and lifts in public buildings, ensuring transport systems like air, rail, and road are inclusive, and enhancing the Information and Communication Technology ecosystem to provide accessible websites and public documents.

Explanation

Electric potential at a point in an electric field is defined as the work done in bringing a unit positive charge from infinity to that point. Mathematically, it is expressed as V = W/q, where W represents work done and q represents the charge. Since work is a scalar quantity and charge is also a scalar quantity, their ratio, which defines electric potential, is a scalar quantity. It possesses magnitude but no specific direction in space, although it can have positive, negative, or zero values depending on the sign of the charge and the reference point. The SI unit of electric potential is the Volt (V), which is equivalent to one Joule per Coulomb (J/C).

Explanation

Tamil Nadu matches with Dodda Betta Peak because it is the highest mountain in the Nilgiri Hills of the Western Ghats at an elevation of 2,637 meters. Rajasthan matches with Gurushikhar Peak as it is the highest point of the Aravalli Range and the state, standing at 1,722 meters near Mount Abu. Nagaland matches with Saramati Peak because it is the highest summit in the Naga Hills, situated on the border with Myanmar at an altitude of 3,842 meters. Madhya Pradesh matches with Dhupgarh Peak, which is the highest elevation in the Satpura Range at 1,350 meters and is located near the hill station of Pachmarhi.

Explanation

Petroleum is a fossil fuel that exists in finite quantities within the Earth's crust. It is formed from the remains of organic matter, primarily ancient marine organisms, that were buried under layers of sediment and subjected to intense heat and pressure over millions of years. Because the rate of its formation is extremely slow compared to the rate of human consumption, it is classified as a non-renewable energy source. Once extracted and burned, petroleum reserves are depleted and cannot be replenished on a human timescale.

Explanation

In the financial year 2019-20, India recorded its highest trade surplus with the United States of America. According to data from the Ministry of Commerce and Industry, India's exports to the USA were valued at approximately $53.09 billion, while imports from the USA stood at about $35.67 billion. This resulted in a significant trade surplus of $17.42 billion. The USA has remained India's top trading partner during this period, and it is one of the few countries with which India consistently maintains a positive trade balance, driven largely by the export of pharmaceuticals, precious stones, and textiles.

Explanation

The P.C. Hota Committee on Civil Services Reforms was constituted by the Government of India on February 3, 2004. Chaired by Purna Chandra Hota, a former Chairman of the Union Public Service Commission (UPSC), the committee was tasked with examining the entire gamut of civil service reforms. Its mandate included reviewing the recruitment process, training modules, performance appraisal systems, and measures to enhance the efficiency and accountability of the bureaucracy. The committee submitted its comprehensive report in July 2004, recommending significant changes such as the introduction of domain-based assignments for senior officers and reforms in the Civil Services Examination entry age and selection process.

Explanation

The Kyoto Protocol, adopted in 1997 under the United Nations Framework Convention on Climate Change (UNFCCC), introduced the concept of carbon credits through its flexible market-based mechanisms. These mechanisms, namely the Clean Development Mechanism (CDM), Joint Implementation (JI), and International Emissions Trading (IET), were designed to help industrialized countries meet their legally binding greenhouse gas emission reduction targets. Under this framework, a carbon credit is a tradable permit or certificate that provides the holder the right to emit one tonne of carbon dioxide or an equivalent amount of a different greenhouse gas (CO₂e). By assigning a monetary value to carbon emissions, the protocol incentivized nations and private companies to invest in cleaner technologies and emission reduction projects globally to earn or trade these credits.

Explanation

The Satavahana rulers were significant patrons of the Prakrit language, which served as their official language for administrative and literary purposes. Most of their inscriptions are found in Prakrit using the Brahmi script. King Hala, the seventeenth ruler of the dynasty, is famously credited with composing the Gathasaptashati, a large collection of Prakrit poems, which highlights the royal support for the language.

During this era, art moved beyond royal courts to receive widespread public support. The construction and decoration of Buddhist monuments, such as the stupas at Amaravati and the rock-cut chaityas at Karle and Kanheri, were funded by collective donations from various segments of society. Inscriptions at these sites record contributions from merchants, artisans like weavers and potters, and ordinary citizens, indicating that the public aspect of art flourished through community participation and guild patronage rather than being restricted to monarchical sponsorship.

Explanation

Crookes glass is a specialized type of optical glass formulated to absorb ultraviolet radiation. It contains cerium oxide (CeO₂), a chemical compound that effectively blocks ultraviolet rays while allowing the majority of visible light to pass through. This unique property makes Crookes glass particularly valuable for manufacturing high-quality sunglasses and protective eyewear, as it prevents harmful UV rays from damaging the human eye without significantly obscuring vision.

Explanation

The Shamal is a north-westerly wind that blows over Iraq and the Persian Gulf states, including Kuwait and Saudi Arabia. It is characterized by being hot, dry, and frequently laden with dust or sand, occurring most strongly during the summer months due to the interaction between the semi-permanent high-pressure cell over North Africa and the thermal low-pressure area over the Indus Valley. Since this wind is a regional phenomenon of the Middle East, it is not found in Austria, a country located in Central Europe.

Explanation

Chloe Zhao directed and produced the 2021 film Nomadland, which won the Academy Award for Best Picture at the 93rd Oscars. In addition to the film winning the top prize, Zhao made history by winning the Academy Award for Best Director, becoming the first woman of color to achieve this feat. The film, which explores the lives of van-dwelling workers in the American West following the Great Recession, was widely recognized for Zhao's unique cinematic style that utilized non-professional actors and natural landscapes to create a grounded, empathetic narrative. Zhao's work on the film also earned her several other accolades during the 2021 awards season, including the Golden Globe and BAFTA for Best Director.

Explanation

The Koryak people are an indigenous ethnic group native to the Russian Far East, specifically inhabiting the Kamchatka Peninsula and the coastal regions along the Sea of Okhotsk. They are culturally and geographically distinct from the indigenous populations of Alaska, which include groups such as the Inupiat, Central Yupik, Aleut, Tlingit, and Haida. While the Koryaks share some circumpolar cultural traits with North American indigenous groups, their ancestral homeland remains within the territory of the Russian Federation rather than Alaska.

Explanation

The Balwant Rai Mehta Committee was appointed in 1957 to examine the Community Development Programme and was the first to recommend a three-tier Panchayati Raj system. The Ashok Mehta Committee was constituted in 1977 by the Janata Government to suggest measures for revitalizing the Panchayati Raj institutions. The G.V.K. Rao Committee (listed as G.K.V. Rao) was appointed by the Planning Commission in 1985 to review administrative arrangements for rural development. Finally, the L.M. Singhvi Committee was set up in 1986 by the Rajiv Gandhi government to recommend ways to strengthen democracy and development at the grassroots level, including the proposal for constitutional status for these bodies. The chronological sequence is 1957, 1977, 1985, and 1986.

Explanation

Article 321 of the Constitution of India specifies the power to extend the functions of Public Service Commissions. It states that an Act made by the Legislature of a State may provide for the exercise of additional functions by the State Public Service Commission regarding the services of the State. This power allows the State Legislature to entrust the commission with responsibilities concerning the services of any local authority, other body corporate constituted by law, or any public institution within the state. Therefore, the Uttar Pradesh State Legislature is the competent authority to extend the functions of the State Public Service Commission of Uttar Pradesh through legislative enactment.

Explanation

Historically, the Teesta River was a major tributary of the Ganga, flowing through the Atrai and Punarbhaba channels into the Padma. Following a series of catastrophic floods and tectonic disturbances in 1787, the river shifted its course abruptly eastward and began discharging into the Brahmaputra (Jamuna) in Bangladesh. This shift is a prominent example of river capturing or avulsion, a process where a river abandons its established channel to follow a new path. Himalayan rivers are particularly prone to this phenomenon because they carry immense sediment loads from the young, fragile mountains and flow through an area of high tectonic activity. The rapid accumulation of silt in riverbeds and the unstable geological nature of the Himalayan foredeep cause rivers to frequently change their courses or capture adjacent drainage systems, making the geomorphological nature of these rivers the direct cause of the Teesta's diversion.

Explanation

Under Article 280 of the Constitution of India, the Finance Commission is a quasi-judicial body established by the President every five years or earlier. Its primary constitutional duty is to make recommendations regarding the distribution of the net proceeds of taxes between the Union and the States, commonly referred to as vertical devolution, and the allocation of these proceeds among the States themselves, known as horizontal devolution. The commission also recommends the principles that should govern the grants-in-aid to the States out of the Consolidated Fund of India, ensuring a balanced fiscal relationship within the Indian federal structure.

Explanation

The Code on Wages, 2019, was enacted to simplify and modernize labour regulations by amalgamating four specific central labour laws into a single framework. These consolidated acts are the Minimum Wages Act, 1948, which sets floor wages for various employments; the Payment of Bonus Act, 1965, which regulates bonus distributions; the Equal Remuneration Act, 1976, which prohibits gender-based discrimination in matters of wages; and the Payment of Wages Act, 1936, which governs the timely payment and authorized deductions of salaries. By integrating these statutes, the Code provides a uniform definition of wages and extends the protection of minimum wage and timely payment provisions to all employees across both the organized and unorganized sectors. The inclusion of these particular acts ensures that the core aspects of financial compensation, parity, and statutory benefits are governed under a cohesive legal structure.

Explanation

Dr. M.A. Ansari was a prominent leader of the Indian National Congress and the Muslim League, serving as the President of the Congress during the Madras session in 1927. His political career was defined by his involvement in the Khilafat Movement, the Non-Cooperation Movement, and mainstream nationalist diplomacy. The Kanpur Bolshevik Conspiracy Case of 1924 was a specific criminal trial initiated by the British colonial government against individuals attempting to organize a communist party in India and propagate revolutionary socialist ideas. The case targeted those accused of conspiring to overthrow the British Raj through the spread of communist ideology and international links with the Comintern. Since Dr. Ansari was a mainstream constitutional and nationalist politician rather than a member of the nascent communist group, he was not among the individuals indicted or associated with this particular conspiracy case.

Explanation

According to the 2011 Census of India, Uttar Pradesh is the most populous state in the country. It recorded a total population of 199,812,341, which accounts for approximately 16.51 percent of India's total population. The state has consistently ranked as the most populous administrative unit in India due to its vast geographical area and high fertility rates. At the time of the 2011 Census, the population of Uttar Pradesh was nearly equivalent to the population of Brazil, highlighting its significant demographic scale within the Indian Union.

Explanation

Article 43A deals with participation of workers in the management of industries, not co-operative societies — the promotion of Co-operative Societies is Article 43B (inserted by the 97th Constitutional Amendment, 2011). Hence option C is NOT correctly matched. The others are correct: Article 50 — separation of the judiciary from the executive; Article 46 — promotion of educational and economic interests of SCs/STs; Article 40 — organisation of Village Panchayats as units of self-government.

Explanation

India currently maintains two permanent and operational research stations in Antarctica, which are Maitri and Bharati. Maitri was established in 1989 in the Schirmacher Oasis and serves as a year-round facility for conducting research in biology, earth sciences, and atmospheric sciences. Bharati, the third Indian station, was commissioned in 2012 at Larsemann Hills to facilitate research in oceanography and continental breakup studies. Although India's first station, Dakshin Gangotri, was established in 1983, it was decommissioned in 1990 after being buried under ice and now serves only as a supply base and transit camp. Consequently, Maitri and Bharati are the only two stations that remain fully functional and inhabited throughout the year for scientific exploration under the Indian Antarctic Programme.

Explanation

Bajrang Punia won the Bronze medal at the Tokyo 2020 Olympics in the men's freestyle 65kg wrestling category. He secured the medal by defeating Kazakhstan's Daulet Niyazbekov with a score of 8-0 in the bronze medal playoff. The silver medal in this event was won by Haji Aliyev of Azerbaijan, while the gold was won by Takuto Otoguro of Japan. Punia's victory made him the sixth Indian wrestler to earn an Olympic medal. Therefore, the pairing of Bajrang Punia with a silver medal is factually incorrect.

Explanation

The Aspirational Districts Programme (ADP) was launched by NITI Aayog in January 2018 with the goal of improving the socio-economic status of 112 most underdeveloped districts across India. In the state of Uttar Pradesh, a total of 8 districts were identified and covered under this initiative. These districts include Bahraich, Balrampur, Chandauli, Chitrakoot, Fatehpur, Shravasti, Siddharthnagar, and Sonbhadra. The selection was based on a composite index of 49 key performance indicators across five broad socio-economic themes: Health and Nutrition, Education, Agriculture and Water Resources, Financial Inclusion and Skill Development, and Basic Infrastructure. The programme operates through the 3Cs strategy of Convergence, Collaboration, and Competition to ensure that these districts catch up with the best-performing districts in the country.

Explanation

The United Nations Population Fund (UNFPA) is the specialized agency of the United Nations responsible for sexual and reproductive health. Since 1978, it has published the State of World Population report annually to highlight emerging issues in the field of international population and development. The 2021 edition of this report, titled My Body is My Own, focused on bodily autonomy and self-determination. This was the first time a United Nations report focused on the power of individuals to make choices about their bodies without fear of violence or coercion, covering aspects such as healthcare, contraception, and sexual consent.

Explanation

Pundarik Vitthal authored Ragamala in the 16th century, a work that details the classification of ragas and their personification through the Ragamala miniature painting tradition. Sri Kantha wrote Rasa Kaumudi, an influential text that explores the relationship between musical structure and aesthetic experience. Somanath is the creator of Raga Vibodh, completed around 1609, which provides detailed descriptions of musical notes and the technical aspects of playing stringed instruments like the Veena. Venkatamakhin, identified in the list as Venkataraman, wrote the Chaturdandi Prakashika in the mid-17th century, which is the foundational treatise for the Melakarta system of raga classification used in Carnatic music.

Explanation

Article 87(1) of the Constitution of India provides for the Special Address by the President. This article mandates that the President shall address both Houses of Parliament assembled together at two specific instances: the commencement of the first session after each general election to the House of the People (Lok Sabha) and the commencement of the first session of each year. This requirement ensures that the government's policies and legislative programs are laid out before the legislature at the start of its term and annually thereafter.

The constitutional provision further specifies that in this special address, the President shall inform Parliament of the causes of its summons. This address is essentially a statement of the government's policy and is drafted by the Union Cabinet. Following the address, each House of Parliament discusses the matters referred to in it through a Motion of Thanks, which is then put to a vote. This procedure is modeled after the Speech from the Throne in the British Parliament and serves as a vital mechanism for parliamentary oversight of the executive's proposed agenda.

Explanation

The Great Reset was launched by the World Economic Forum in June 2020 as a proposal to rebuild the global economy and social systems sustainably following the disruptions caused by the COVID-19 pandemic. Introduced by the WEF Executive Chairman Klaus Schwab and Prince Charles, the initiative aims to direct the world towards a more resilient and equitable stakeholder capitalism. It focuses on three key pillars: steering the market toward fairer outcomes, ensuring that investments advance shared goals like equality and sustainability, and harnessing the innovations of the Fourth Industrial Revolution for the public good. The initiative served as the central theme for the World Economic Forum’s 2021 summit to address the long-term impacts of the global health crisis.

Explanation

Cloves are the aromatic, dried, unopened flower buds of the Syzygium aromaticum tree, a member of the Myrtaceae family. These buds are harvested while they are still immature and have just turned from green to a pinkish-red color. Morphologically, a clove consists of a long, narrow stalk called the hypanthium, which is topped by four calyx teeth and a small central ball. This ball is composed of four unopened petals that protect the developing reproductive organs, such as the stamens and style, inside. The drying process transforms these tender buds into the hard, dark brown spice used globally. The high concentration of essential oils, particularly eugenol, is stored within these floral structures, providing the characteristic pungent aroma and flavor.

Explanation

Headline inflation is the measure of total inflation within an economy, encompassing the entire basket of goods and services, including volatile components such as food and energy. In India, the Reserve Bank of India (RBI) formally adopted the Consumer Price Index (CPI) Combined as the primary anchor for measuring headline inflation in April 2014. This transition occurred following the recommendations of the Urjit Patel Committee, which argued that a consumer-centric index more accurately reflects the cost of living and the inflationary pressures faced by the general population than the Wholesale Price Index (WPI). CPI Combined integrates price data from both rural and urban areas to provide a comprehensive national picture. It serves as the benchmark for the Flexible Inflation Targeting (FIT) framework, where the RBI aims to maintain inflation at a target of 4% with a tolerance band of ± 2%.

Explanation

According to Article 280(2) of the Constitution of India, the Parliament is empowered to determine the qualifications of the Chairman and members of the Finance Commission and the manner of their selection. In exercise of this power, the Parliament enacted the Finance Commission (Miscellaneous Provisions) Act, 1951, which specifies that the Chairman should be a person having experience in public affairs and the four other members should be selected from among persons who are, or have been, or are qualified to be appointed as Judges of a High Court, or have special knowledge of finances and accounts of Government, or have had wide experience in financial matters and in administration, or have special knowledge of economics. Conversely, Article 280(1) mandates that the Chairman and members are appointed by the President of India.

Explanation

Aam Aadmi Bima Yojana (A) matches with 2007 (3) because it was launched on October 2, 2007, to provide death and disability insurance to rural landless households in India. Pradhan Mantri Atmanirbhar Swasthya Bharat Yojana (B) matches with 2021 (1) as it was announced in the Union Budget 2021-22 and launched in October 2021 to strengthen the primary, secondary, and tertiary health care systems across the country. Pradhan Mantri Jan Aarogya Yojana (C) matches with 2018 (4) since it was officially launched on September 23, 2018, to provide health insurance coverage of up to 5 lakh rupees per family per year for secondary and tertiary care hospitalization. Pradhan Mantri Suraksha Bima Yojana (D) matches with 2016 (2) because, while formally introduced in May 2015, the scheme saw its first full cycle of nationwide implementation and enrollment during the 2016 period.

Explanation

Bal Gangadhar Tilak was a prominent leader of the Extremist faction of the Indian National Congress and a key figure in the Indian independence movement. Despite his massive popularity and significant contributions to the national struggle, including his role in the Home Rule League and the Swadeshi movement, he never occupied the position of President of the Indian National Congress. His name was frequently considered for the role, particularly during the period of heightened tension between Moderates and Extremists leading up to the 1907 Surat split, but he was never officially elected to preside over an annual session during his lifetime.
