UPPSC Prelims 2023 Question Paper with Answers & Explanations

Explanation

The International Day for the Eradication of Poverty is observed globally on October 17 each year to acknowledge the effort and struggle of people living in poverty. For the 2022-2023 cycle, the United Nations designated the theme Dignity for all in practice. This theme underscores that dignity is not an abstract concept but a fundamental right that forms the basis of all other human rights. It focuses on the reality that millions of people living in extreme poverty continue to face daily violations of their dignity, including restricted access to healthcare, education, and safe working conditions. The theme calls for the implementation of social justice and environmental protection measures that treat every person with respect, ensuring that the commitment to end poverty is translated into meaningful actions that restore dignity to the marginalized.

Explanation

The relationship between human resources and economic development is characterized by a reciprocal causal link. Economic development affects population growth through the demographic transition process; as a country progresses, improvements in healthcare, education, and income levels typically lead to a decline in mortality and eventually a reduction in fertility rates. Conversely, population growth influences economic development by determining the supply of labor and the level of domestic demand. While a large, skilled population can drive growth through increased productivity and innovation—often referred to as the demographic dividend—the rate of population growth also dictates the required investment in public services and infrastructure. Therefore, both the impact of economic progress on demographic trends and the role of population dynamics in shaping economic outcomes are fundamental aspects of human resource analysis in development economics.

Explanation

The chronological sequence of the formation of the Indian Constitution begins with the first meeting of the Constituent Assembly on December 9, 1946, where Dr. Sachchidananda Sinha was elected as the temporary President. Following the independence of India, the Drafting Committee was appointed on August 29, 1947, with Dr. B.R. Ambedkar as its Chairman to prepare a draft for the new Constitution. The drafting process culminated on November 26, 1949, when the Constitution was adopted and enacted by the Constituent Assembly, as noted in the Preamble. The final step was the date of commencement of the Constitution on January 26, 1950, which marked the transition of India into a sovereign democratic republic.

Explanation

Peptic ulcers (A) are primarily caused by the bacterium Helicobacter pylori, which colonizes the stomach lining and causes chronic inflammation, a discovery that earned Marshall and Warren the Nobel Prize. Dengue (B) is an acute febrile illness caused by the dengue virus, which is transmitted to humans through the bite of infected Aedes aegypti or Aedes albopictus mosquitoes. Elephant Foot (C), scientifically known as lymphatic filariasis, results from infection with parasitic filarial worms like Wuchereria bancrofti that reside in the lymphatic system. Malaria (D) is a disease caused by Plasmodium parasites, which are microscopic single-celled protozoa transmitted through the bites of infected female Anopheles mosquitoes.

Explanation

Mirat-e-Sikandari, written by Shaikh Sikandar in 1611, is a detailed historical account of the independent Sultanate of Gujarat until its conquest by the Mughal Emperor Akbar. Burhan-e-Masir, authored by Sayyid Ali Tabataba, provides a comprehensive history of the Bahmani Sultanate and the Nizam Shahi rulers of Ahmadnagar. Riyaz-us-Salatin, composed by Ghulam Husain Salim, is recognized as the first formal history of Bengal during the period of Muslim rule, covering events up to the late 18th century. Riyaz-ul-Insha is a compilation of letters and diplomatic dispatches written by Mahmud Gawan, the celebrated prime minister of the Bahmani Kingdom, which sheds light on the political and administrative conditions of the Deccan.

Explanation

Population control is a critical requirement for environmental sustainability because an ever-increasing population leads to the over-exploitation of natural resources, increased waste production, and higher pollution levels. By managing population growth, a nation can reduce the anthropogenic pressure on ecosystems, ensuring that resource consumption does not exceed the carrying capacity of the environment.

Conversely, rapid population growth is a primary driver of environmental degradation. It necessitates the conversion of forests into agricultural or urban land, causes depletion of groundwater, and contributes significantly to biodiversity loss and climate change. Such rapid expansion disrupts rather than maintains the ecological balance, making the reasoning provided fundamentally incorrect. Therefore, the assertion regarding the necessity of population control is true, while the claim that rapid growth maintains environmental balance is false.

Explanation

The Delhi-Lahore Conspiracy Case of 1912 involved an assassination attempt on Viceroy Lord Hardinge during a ceremonial procession in Delhi. This operation was a coordinated effort by the revolutionary organization Anushilan Samiti. The plan was conceived and executed by Rash Behari Bose and Sachindra Sanyal, who were key leaders within the Samiti network. Rash Behari Bose utilized the underground infrastructure of the Anushilan Samiti to organize the attack, which took place as the Viceroy was entering the new capital through Chandni Chowk. Basant Kumar Biswas, a revolutionary associated with the group, threw the bomb while disguised in a veil. The event proved the ability of the Anushilan Samiti to carry out sophisticated militant activities far beyond its original base in Bengal, marking a significant moment in the Indian revolutionary movement.

Explanation

Chris Hipkins assumed office as the 41st Prime Minister of New Zealand on January 25, 2023. He was unanimously elected as the leader of the New Zealand Labour Party on January 22, 2023, after being the sole nominee for the position. Before taking over the premiership, he had served in the New Zealand Parliament since 2008 and held several high-profile cabinet positions, most notably as the Minister for COVID-19 Response and the Minister of Education. His appointment followed a leadership transition within the governing Labour Party mid-term, leading to his formal swearing-in by the Governor-General.

Explanation

The Nyaya school of Hindu philosophy was founded by the sage Gautama, who is also known as Aksapada Gautama. This school is fundamentally concerned with logic, methodology, and epistemology. Its foundational text, the Nyaya Sutras, was composed by Gautama and establishes a systematic framework for logical reasoning. Nyaya philosophy posits that human suffering stems from ignorance, and liberation can only be achieved through the acquisition of valid knowledge. To this end, it identifies four reliable means of obtaining knowledge: perception (pratyaksha), inference (anumana), comparison (upamana), and verbal testimony (shabda). The school's emphasis on a rational and scientific approach to understanding reality provided the logical foundation that was subsequently adopted by many other systems of Indian philosophy.

Explanation

The first census in India was conducted in 1871 under the viceroyalty of Lord Mayo. This exercise was a non-synchronous census, meaning it was carried out across different parts of the country at different times between 1867 and 1872 rather than on a single day. It marked the first systematic and modern effort by the British administration to gather demographic information about the Indian population. This process laid the groundwork for the first synchronous and complete decennial census that followed in 1881.

Explanation

In the Union Budget 2023-24, the allocation for the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) was reduced to ₹60,000 crore. This represents a decline of approximately 18 percent compared to the 2022-23 Budget Estimate (BE) of ₹73,000 crore and a steeper 33 percent drop when compared to the Revised Estimate (RE) of ₹89,400 crore. This was the highest percentage decline recorded among all major flagship social sector schemes in that budget cycle.

The second statement is incorrect because the highest percentage growth in scheme-wise allocation was recorded for the Pradhan Mantri Awas Yojana (PMAY). The outlay for PMAY was enhanced by 66 percent to ₹79,590 crore from the previous year's BE of ₹48,000 crore. In comparison, the Jal Jeevan Mission saw its allocation increase from ₹60,000 crore to ₹70,000 crore, which is a growth of approximately 16.7 percent.

Explanation

Prime Minister Narendra Modi inaugurated the Hindustan Aeronautics Limited (HAL) Helicopter Factory in Tumkuru, Karnataka, in February 2023. This facility is India's largest helicopter manufacturing plant and is a greenfield project spread across 615 acres. The factory was established to initially produce the Light Utility Helicopter (LUH), which is a 3-ton class, indigenously designed multipurpose helicopter. The plant is equipped with state-of-the-art manufacturing technologies and is planned to produce approximately 30 helicopters per year, with the capacity to scale up to 60 and eventually 90 units annually. This project is a significant step toward achieving self-reliance in defense manufacturing and supporting the Atmanirbhar Bharat initiative by reducing dependence on imports for rotorcraft requirements.

Explanation

The composition Ganesh Dev Leela was authored by the renowned saint-poetess Gauribai of Dungarpur. Known as the Mira of Vagad, Gauribai was a significant figure in the Bhakti movement in Rajasthan and wrote several devotional works including Ganesh Dev Leela and Kirtan Mala. Mangabai is not associated with this particular literary work, making this pair an incorrect match in the given list of poetesses and their compositions.

Explanation

According to Article 243K of the Constitution of India, introduced by the 73rd Amendment Act of 1992, the superintendence, direction, and control of the preparation of electoral rolls for, and the conduct of, all elections to the Panchayats are vested in the State Election Commission. This commission is an independent constitutional body headed by a State Election Commissioner appointed by the Governor of the respective state. While the Election Commission of India manages national and state-level elections, the mandate for local self-government elections at the village, intermediate, and district levels lies exclusively with the State Election Commission to ensure the autonomy of the Panchayati Raj institutions.

Explanation

The Ashok Mehta Committee, appointed by the Janata Government in 1977, recommended the replacement of the three-tier Panchayati Raj system with a two-tier system. This structure was designed to consist of the Zila Parishad at the district level and the Mandal Panchayat at the lower level, which would represent a cluster of villages with a combined population of 15,000 to 20,000. The committee emphasized that the district should be the first point of decentralization under popular supervision below the state level, serving as the pivot of the entire system. According to the committee, the district level was the most appropriate unit for administrative and technical planning, and the Zila Parishad was intended to be the executive body responsible for developmental functions at that level.

Explanation

Kanpur was not selected as one of the host cities for the G20 meetings held in Uttar Pradesh during India's G20 Presidency. The Union Government and the State Government of Uttar Pradesh designated four specific cities to host the eleven scheduled meetings: Varanasi, Lucknow, Agra, and Greater Noida. These locations were chosen based on their existing infrastructure, international connectivity, and ability to showcase the cultural and economic diversity of the state. Kanpur did not figure in the official itinerary for any of the 200 sessions organized across the country, as the state's representation was focused on the major tourism, political, and industrial corridors represented by the other four cities.

Explanation

The Charak Samhita, an ancient Indian medicinal treatise and a foundational pillar of Ayurveda, is systematically organized into 8 distinct sections called Sthanas. These sections are further divided into a total of 120 chapters or Adhyayas. The eight Sthanas include Sutra-sthana, which covers general principles; Nidana-sthana, focusing on pathology; Vimana-sthana, dealing with specific determination and training; Sharira-sthana, covering anatomy and embryology; Indriya-sthana, regarding prognosis; Chikitsa-sthana, detailing therapeutics; Kalpa-sthana, on pharmaceutics; and Siddhi-sthana, describing success in treatment. This structural arrangement provides a comprehensive framework for the study and practice of internal medicine, ensuring that theoretical concepts, diagnostic methods, and practical treatments are thoroughly addressed within the 120 chapters of the text.

Explanation

The human heart is an essential muscular organ that facilitates double circulation through four distinct chambers. It consists of two superior chambers called the right and left atria and two inferior chambers called the right and left ventricles. The right atrium receives deoxygenated blood from the body, which then flows into the right ventricle to be pumped to the lungs. Conversely, the left atrium receives oxygenated blood from the lungs, which moves into the left ventricle to be pumped throughout the systemic circulation. This four-chambered structure ensures that oxygenated and deoxygenated blood remain separate, allowing for efficient oxygen delivery to tissues throughout the body.

Explanation

The Amrit Bharat Station Scheme was launched by the Ministry of Railways in December 2022 to modernize railway stations across the Indian Railways network. As per the data released by the Ministry of Railways in February 2023, a total of 1275 stations were identified for development under this scheme across the country. Uttar Pradesh was allocated the highest number of stations for modernization, with 149 stations identified within the state. The scheme involves the preparation of master plans and their implementation in phases to improve amenities such as station access, circulating areas, waiting halls, executive lounges, and overall infrastructure to enhance the passenger experience.

Explanation

Moderna, also known as mRNA-1273, utilizes messenger RNA technology to protect against Covid-19. This vaccine works by introducing a synthetic strand of mRNA into the body that contains the genetic instructions for cells to produce the SARS-CoV-2 spike protein. Once the cells synthesize this protein, the immune system recognizes it as a foreign invader and generates a specific immune response, including the production of antibodies and the activation of T-cells. This method does not use any part of the actual virus, instead relying on the body's own protein-making machinery to trigger a defensive reaction that provides immunity against future infection by the virus.

Explanation

The United Provinces Kisan Sabha was established in February 1918 primarily through the efforts of Indra Narayan Dwivedi and Gauri Shankar Misra, with the active support and guidance of Madan Mohan Malaviya. The organization was formed to address the grievances of the peasantry in the United Provinces, particularly against the high rents and arbitrary evictions practiced by landlords and taluqdars. Indra Narayan Dwivedi was a key organizer whose work helped the Kisan Sabha expand rapidly, leading to the establishment of hundreds of branches across various districts such as Allahabad, Rae Bareli, and Pratapgarh within a short period.

Explanation

During the Later Vedic period, the administrative machinery of the king became more complex with the inclusion of various high-ranking officials known as the Ratnins or jewel-bearers. The Bhagadugha was one of these key functionaries whose primary responsibility was the collection of the royal share of agricultural produce and other taxes. The title is etymologically derived from the word bhaga, which means share or portion, and dugha, signifying the collector or milker. This official played a critical role in the transition from a voluntary system of tributes, known as bali, to a more formalized and mandatory revenue collection system necessary for maintaining the expanding state and its army.

Explanation

Article 324 (Item A) establishes the Election Commission of India, vesting it with the authority to supervise, direct, and control elections to Parliament and State Legislatures. Article 315 (Item B) provides for the creation of Public Service Commissions for the Union and the States to conduct examinations for appointments to the various civil services. Article 280 (Item C) mandates the President to constitute a Finance Commission every five years to recommend the allocation of net tax proceeds between the Center and the States. Article 338 (Item D) provides for the National Commission for Scheduled Castes to investigate and monitor all matters relating to the constitutional and legal safeguards provided for Scheduled Castes in India.

Explanation

In the Union Budget 2023-24, the Central Government announced that states would be allowed a fiscal deficit of 3.5 per cent of their Gross State Domestic Product (GSDP). This limit was set to provide states with sufficient fiscal space to maintain their capital expenditure momentum while adhering to a path of fiscal consolidation. Within this 3.5 per cent ceiling, a specific portion of 0.5 per cent is tied to the implementation of power sector reforms, incentivizing states to improve the operational and financial efficiency of their power utilities. This provision aligns with the recommendations of the 15th Finance Commission regarding state-level borrowing limits and fiscal management.

Explanation

The Milinda Panha, or Questions of Milinda, is a significant Buddhist text written in the form of a dialogue between the Indo-Greek King Menander I, known as Milinda in Pali, and the Buddhist sage Nagasena. Composed around the 2nd century BCE, the work details Nagasena's skillful responses to the king's complex philosophical questions regarding Buddhist doctrine, the nature of the self, and the path to enlightenment. One of the most famous passages involves Nagasena using the analogy of a chariot to explain the concept of Anatta, or the lack of a permanent, independent soul. The depth of Nagasena's wisdom throughout these exchanges ultimately leads to the king's conversion to Buddhism.

Explanation

Spare is a memoir written by Prince Harry, the Duke of Sussex, which was officially released on January 10, 2023. The book provides a personal and candid account of his life within the British royal family, including his experiences following the death of his mother, Princess Diana, his military service in Afghanistan, and the internal conflicts that led to his decision to step back from senior royal duties. The title Spare is a direct reference to the aristocratic adage of an heir and a spare, reflecting his secondary position in the line of succession relative to his elder brother. The memoir was ghostwritten by J.R. Moehringer and became a global bestseller immediately upon its publication.

Explanation

In February 2023, India received a second batch of 12 Cheetahs from South Africa, comprising seven males and five females, which were released into the Kuno National Park in Madhya Pradesh. This translocation followed an inter-governmental agreement between India and South Africa to establish a viable cheetah population in the country. Project Cheetah is the world first inter-continental large wild carnivore translocation project, driven by the Indian government decision to make the restoration of this extinct species a national priority. By reintroducing the cheetah, India aims to restore its open forest and grassland ecosystems, where the cheetah formerly served as a flagship species. The status of cheetah restoration as a high-priority conservation goal directly explains why the government is actively importing these animals from African nations.

Explanation

Deakin University, an Australian institution, is the first foreign university to receive approval to establish an independent international branch campus in India. This milestone was achieved under the International Financial Services Centres Authority (Setting up and Operation of International Branch Campuses and Foreign Universities) Regulations, 2022. The campus is located in GIFT City (Gujarat International Finance Tec-City) in Gandhinagar, Gujarat, providing students with access to international standards of education within India. This initiative aligns with the National Education Policy 2020, which seeks to facilitate the entry of top-ranked global universities to enhance the local academic landscape.

Explanation

India's G20 logo features the Earth placed atop a lotus, which is the national flower of India. The lotus in this design specifically includes seven petals. According to the official explanation provided by the Government of India during the unveiling of the logo, these seven petals represent the seven continents of the world. Furthermore, they symbolize the seven notes of music, together signifying the theme of global harmony and unity under the vision of Vasudhaiva Kutumbakam, or One Earth, One Family, One Future.

Explanation

Meira Kumar, a former Indian Foreign Service officer and five-time Member of Parliament, was elected as the first woman Speaker of the Lok Sabha on June 3, 2009. She presided over the 15th Lok Sabha from 2009 to 2014. Representing the Sasaram constituency in Bihar as a member of the Indian National Congress, she was elected to the post unopposed. Her appointment marked a significant milestone in Indian parliamentary history, as she was the first female presiding officer of the lower house since its first session in 1952. Prior to this role, she served as a Union Cabinet Minister in the Ministry of Social Justice and Empowerment.

Explanation

The Economic Survey 2022-23 highlights that the Indian e-commerce market is undergoing a significant transformation in its product mix. According to the industry projections cited in the survey, the categories of fashion, grocery, and general merchandise are expected to capture nearly two-thirds of the Indian e-commerce market by the year 2027. The statement is incorrect because it cites the year 2030 instead of 2027. This growth is driven by the expansion of the digital ecosystem into Tier II and Tier III cities and a shift in consumer behavior from electronics-led online shopping to daily essentials and lifestyle products.

Explanation

The chronological sequence of the Peshwas reflects the consolidation and peak of Maratha power in the 18th century. Balaji Vishwanath served as the first hereditary Peshwa from 1713 to 1720, instrumental in securing the rights of Chhatrapati Shahu. He was succeeded by his son, Bajirao I, who reigned from 1720 to 1740 and is celebrated for expanding Maratha influence into North India. Following the reign of Balaji Baji Rao, Madhav Rao I took office from 1761 to 1772, during which he successfully restored Maratha prestige after the Third Battle of Panipat. Upon his untimely death, his younger brother Narayan Rao became the Peshwa in 1772, but his reign was cut short by his assassination in 1773. Therefore, the correct chronological order is Balaji Vishwanath, Bajirao I, Madhav Rao I, and Narayan Rao.

Explanation

Donetsk is the primary city and administrative center of the Donets Basin, widely known as the Donbas, which serves as the principal coal-producing region of Ukraine. This area contains the country's most extensive deposits of high-quality coal, including anthracite and bituminous varieties. The city's growth and industrial identity are deeply rooted in its proximity to these coal fields, which have fueled Ukraine's heavy metallurgy and energy sectors for over a century. As the urban heart of the Donbas, Donetsk remains the most significant center for the extraction and processing of coal within the nation's borders.

Explanation

Ocean salinity is primarily determined by the balance between evaporation and precipitation. In the subtropical regions near the Tropic of Cancer and the Tropic of Capricorn, the presence of the Subtropical High Pressure Belt results in stable atmospheric conditions characterized by clear skies, high solar radiation, and minimal rainfall. These conditions lead to extremely high rates of evaporation relative to the amount of fresh water added through precipitation or river runoff. Consequently, the concentration of dissolved salts in the surface waters increases, making these subtropical latitudes the zones of maximum surface salinity in the global oceans. While the equatorial region receives more heat, its salinity is lower due to heavy daily convectional rainfall and higher humidity which limits evaporation.

Explanation

Gunnar Myrdal, a Swedish economist and Nobel Prize winner, authored the book The Challenge of World Poverty: A World Anti-Poverty Program in Outline, which was published in 1970. This work serves as a practical summary and policy-oriented sequel to his extensive three-volume study, Asian Drama: An Inquiry into the Poverty of Nations. In the book, Myrdal critiqued conventional economic theories for ignoring social and institutional factors. He advocated for radical internal reforms in developing countries, such as land redistribution and educational improvements, while also calling for more equitable trade and aid policies from developed nations to combat global inequality and underdevelopment.

Explanation

E.V. Ramaswami Nayakar, popularly known as Periyar, joined the Indian National Congress in 1919. He was a dedicated participant in the Non-Cooperation Movement between 1920 and 1922, where he led protests against British rule, advocated for the use of Khadi, and famously picketed toddy shops. His involvement in these activities led to his arrest and imprisonment on multiple occasions, demonstrating his active engagement with the Gandhian struggle during that period.

His departure from the Congress occurred in 1925 following deep ideological differences regarding social equality and communal representation. During the Kanchipuram session of the Tamil Nadu Congress Committee in 1925, Periyar proposed a resolution for providing reservations for non-Brahmins in government jobs and representative bodies. When the Congress leadership refused to pass this resolution, he resigned from the party. Immediately after leaving the Congress, he launched the Self-Respect Movement to campaign for the rights of non-Brahmins and to eliminate caste-based discrimination.

Explanation

New Zealand's Smokefree Aotearoa 2025 Action Plan, supported by the pioneering legislation passed in December 2022, sets a specific target to make the country effectively smoke-free by 2025. The government defines this goal as achieving a smoking prevalence of less than 5 percent across all population groups. To reach this objective, the law introduced stringent measures such as prohibiting the sale of smoked tobacco products to anyone born on or after January 1, 2009, significantly reducing the permitted nicotine levels in tobacco, and dramatically decreasing the number of authorized tobacco retailers nationwide.

Explanation

On January 15, 2023, Yeti Airlines Flight 691, an ATR 72-500 aircraft, crashed while on its approach to land at the newly inaugurated Pokhara International Airport. The flight had departed from Kathmandu's Tribhuvan International Airport carrying 68 passengers and 4 crew members. The aircraft plunged into a gorge on the banks of the Seti River, resulting in the deaths of all 72 individuals on board. This incident was recorded as the deadliest plane crash in Nepal since the 1992 Pakistan International Airlines crash. Subsequent investigations pointed toward human error, specifically the inadvertent feathering of the propellers by the flight crew, which led to an aerodynamic stall and the subsequent crash.

Explanation

The Climate Change Performance Index (CCPI) 2022 ranked India 10th in the world for its performance in managing greenhouse gas emissions. This index, published annually by Germanwatch, the NewClimate Institute, and the Climate Action Network, monitors the climate protection efforts of 60 countries and the European Union, which together account for over 90 percent of global emissions. The ranking is determined by evaluating performance across four categories: Greenhouse Gas (GHG) Emissions, Renewable Energy, Energy Use, and Climate Policy. India's high placement in the 2022 report was largely driven by its relatively low per capita emissions and its progress toward meeting the mitigation targets set under the Paris Agreement. The assessment placed India among the top-performing nations, as the first three spots in the index were left vacant because no country performed well enough across all categories to earn a very high rating.

Explanation

A watershed is a topographically delineated area that functions as a natural hydrological unit. It encompasses all the land surface and subsurface area that drains water to a common outlet, such as a stream, river, lake, or ocean. The process involves the collection of precipitation that falls within its boundaries, the storage of this water in soil, vegetation, and underground aquifers, and the eventual release of water through surface runoff and baseflow into drainage channels. By integrating these functions, a watershed regulates the flow of water and supports the biological and chemical processes essential for a healthy ecosystem.

Explanation

The Human Development Report 2021-22, released by the United Nations Development Programme (UNDP), titled Uncertain Times, Unsettled Lives, showed that India's rank on the Human Development Index (HDI) moved to 132 out of 191 countries. In the 2020 report, India had been ranked 131. In the context of global rankings, moving from a lower numerical position to a higher one signifies a decline in standing, which is correctly described as a slip. This drop was largely attributed to a decrease in life expectancy at birth from 69.7 years to 67.2 years. The decline was part of a broader global trend where HDI values fell in 90 percent of countries due to the compound effects of the COVID-19 pandemic, environmental crises, and economic instability. India's HDI score of 0.633 placed it in the medium human development category.

Explanation

In the Union Budget 2023-24, the component of Subsidies was allocated 7 percent of the total expenditure. The figures mentioned in the statement, such as 9 percent, actually represent the shares for Centrally Sponsored Schemes and Finance Commission transfers, while the 20 percent figure is the allocation for Interest Payments. Because the official Rupee Goes To chart specifies subsidies at only 7 percent, this statement contains incorrect statistical data regarding the total outlay.

Explanation

The Optimum Population Theory was propounded by Edwin Cannan, who defined the ideal population as the point where the ratio of population to resources produces the maximum income per capita. The Social Mal-adjustment Theory is attributed to Henry George, who argued that the problems often blamed on overpopulation actually result from social injustice and the unequal distribution of wealth. The Demographic Transition Theory was first formulated by Warren Thompson in 1929, describing the historical shift from high birth and death rates to low birth and death rates during industrialization. The Population-Food Supply Relationship Theory is the core of Thomas Robert Malthus's work, which posits that population grows at a geometric rate while the food supply only increases at an arithmetic rate, leading to inevitable scarcity.

Explanation

Nepenthes is a genus of carnivorous plants, commonly known as tropical pitcher plants or monkey cups, primarily found in nitrogen-poor environments such as tropical rainforests. To supplement their nutrient intake, these plants have evolved specialized leaves modified into pitfall traps. These pitchers contain a digestive fluid that breaks down captured insects and other small organisms. Insects are lured into the trap by nectar secretions and attractive coloration; once they land on the slippery rim, they fall into the pitcher, where enzymes and bacteria digest them. This process allows the plant to absorb essential nutrients, especially nitrogen and phosphorus, which are deficient in its natural habitat.

Explanation

In the Union Budget 2023-24, the expenditure profile known as Rupee Goes To shows that subsidies accounted for 7 percent of the total expenditure. The figure of 9 percent mentioned in the option was actually the allocation for Centrally Sponsored Schemes as well as for Finance Commission and other transfers. Other major components included interest payments at 20 percent, states' share of taxes and duties at 18 percent, and defence expenditure at 8 percent.

Explanation

(A) matches with 3 because Edwin Cannan developed the concept of the optimum population level that maximizes real income per head. (B) matches with 4 as Henry George attributed the problems of overpopulation to social maladjustment and the inequitable distribution of wealth. (C) matches with 1 since Warren Thompson first formulated the stages of demographic change based on birth and death rate trends in 1929. (D) matches with 2 because Thomas Malthus famously theorized that population grows at a geometric rate while the food supply grows only at an arithmetic rate.

Explanation

Nepenthes is a genus of carnivorous plants commonly known as tropical pitcher plants or monkey cups. These plants possess modified leaf structures that form deep, fluid-filled pitfalls called pitchers. Primarily found in nitrogen-deficient environments like tropical rainforests and bogs, Nepenthes has evolved carnivory to supplement its nutrient intake. The plant attracts insects using a combination of nectar, scent, and vivid coloration. When an insect lands on the slippery rim or peristome of the pitcher, it loses its footing and falls into the digestive fluid at the bottom. The plant then secretes specialized enzymes to break down the prey and absorb essential minerals such as nitrogen and phosphorus.

Explanation

The Rio Grande serves as a major geographical and political boundary, forming approximately 1,254 miles of the international border between the United States and Mexico. Beginning at El Paso, Texas, the river separates the U.S. state of Texas from the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas before emptying into the Gulf of Mexico. In Mexico, the river is known as the Río Bravo or Río Bravo del Norte. This natural frontier was formally established by the Treaty of Guadalupe Hidalgo in 1848 and the Gadsden Purchase of 1853, following the Mexican-American War. It remains one of the longest river systems in North America and is a critical resource for agriculture and municipal water supplies in the border region.

Explanation

Niti Pass is situated at an altitude of approximately 5,068 meters in the Chamoli district of Uttarakhand. It is a prominent high-altitude mountain pass in the Kumaon Himalayas that connects the state of Uttarakhand with the Tibet Autonomous Region of China. Historically, the Niti Pass served as an essential trade route between India and Tibet for centuries before its closure following the 1962 conflict. It remains one of the key geographical landmarks in the northern reaches of Uttarakhand, alongside other major passes like Mana Pass and Lipulekh Pass.

Explanation

Trophic levels represent the functional positions or steps that organisms occupy within a food chain based on their specific source of nutrition and energy. In any ecosystem, energy flows from producers to various levels of consumers in a sequential process of eating and being eaten. Each link in this chain constitutes a distinct trophic level, beginning with primary producers at the first level, followed by primary consumers at the second level, and moving up to secondary and tertiary consumers. Thus, the hierarchical structure of trophic levels is fundamentally defined by the collective organisms linked through these feeding relationships in a food chain.

Explanation

In the Union Budget 2023-24, the Ministry of Health and Family Welfare was allocated a total sum of ₹89,155.05 crore. This total budgetary provision is divided between the Department of Health and Family Welfare, which received ₹86,175.05 crore, and the Department of Health Research, which was allocated ₹2,980 crore. The figure of ₹89,155 crore represents the consolidated financial resources dedicated to central health initiatives, public health services, and medical research for the 2023-24 fiscal period.

Explanation

Article 98 of the Constitution of India governs the Secretariat of Parliament. Under Article 98(1), each House of Parliament is mandated to have its own separate secretarial staff. However, the proviso to this clause specifically clarifies that the creation of posts common to both Houses of Parliament is not prohibited, allowing for joint administrative roles where necessary.

Furthermore, Article 98(2) establishes that Parliament has the constitutional authority to regulate the recruitment and the conditions of service of the secretarial staff of either House through legislation. Article 98(3) provides that until Parliament makes such a law, the President may, after consultation with the Speaker of the Lok Sabha or the Chairman of the Rajya Sabha, make rules for recruitment and service conditions. Since both the creation of joint posts and the legislative power to regulate service conditions are explicitly provided for in the Constitution, both statements are accurate.

Explanation

Taiwanese President Tsai Ing-wen announced on December 27, 2022, that the mandatory military service for men would be extended from four months to one year. This policy change applies to male citizens born on or after January 1, 2005. The decision was made to enhance the island's combat readiness and national defense capabilities in response to increasing regional security threats. In addition to the longer duration, the government also introduced higher monthly pay for conscripts and more rigorous training modules that include the use of modern technology such as drones and anti-tank weapons. This move marked a significant shift in Taiwan's defense strategy, moving back toward a more robust conscription system that had been gradually reduced over previous decades.

Explanation

Explanation

Diphtheria is caused by the bacterium Corynebacterium diphtheriae, which produces a potent exotoxin responsible for the disease's symptoms. The vaccine against diphtheria is a toxoid vaccine, which uses a chemically or thermally inactivated version of this toxin. By treating the toxin with an agent like formaldehyde, its harmful effects are neutralized while its ability to stimulate an immune response remains intact. Upon vaccination, the body produces specific antitoxins that can neutralize the natural toxin if an infection occurs. This type of immunization is highly effective because it targets the primary cause of pathology in diphtheria rather than the bacteria themselves.

Explanation

Azolla is a small, free-floating aquatic fern that is widely recognized as a highly efficient biofertilizer for water-logged rice cultivation. Its utility stems from its unique symbiotic relationship with the nitrogen-fixing cyanobacterium Anabaena azollae, which lives within the dorsal lobes of its leaves. This bacterium captures atmospheric nitrogen and converts it into a form that the plant can absorb. When incorporated into the soil or allowed to decompose naturally in the paddy field, Azolla releases significant amounts of nitrogen and organic matter, enhancing soil fertility and boosting rice productivity. It also helps in suppressing weed growth and reducing ammonia volatilization in the flooded field environment.

Explanation

Under Article 3 of the Constitution of India, any bill intended to change the boundaries of a state can be introduced in either House of Parliament only with the prior recommendation of the President. Before making such a recommendation, the President is constitutionally required to refer the bill to the legislature of the affected state to obtain its views within a specified period. This confirms that Assertion (A) is true. Reason (R) is also true because the President and the Parliament are not legally bound to follow the views or proposals submitted by the State Legislature; they may proceed with the changes regardless of whether the state agrees or disagrees. While both statements are accurate descriptions of the process defined in Article 3 and validated by judicial precedents like the Babulal Parate case, the non-binding nature of the state's input does not explain the procedural necessity of seeking those views in the first place. The two statements represent distinct characteristics of India's federal structure where the Union maintains ultimate authority over state geography.

Explanation

Nitrous oxide, which has the chemical formula N₂O, is popularly known as laughing gas due to the euphoric effects it produces when inhaled. It is a colorless, non-flammable gas with a slightly sweet odor and taste. First discovered by Joseph Priestley in 1772 and further researched by Humphry Davy, the gas acts as a dissociative anesthetic. In medical and dental settings, it is commonly used for its analgesic and anesthetic properties to help patients relax and manage pain during minor procedures. The nickname laughing gas arises from its ability to induce a state of relaxation and occasional fits of laughter or giggling in individuals who breathe it in. Outside of medicine, it is also utilized as an oxidizer in rocketry and as a propellant in the food industry for aerosol products.

Explanation

Khan Bahadur Khan Rohilla, the grandson of the Rohilla chief Hafiz Rahmat Khan, spearheaded the 1857 uprising in Bareilly. He successfully mobilized a large force of local soldiers and established an independent administration, ruling the region as a representative or Viceroy of the Mughal Emperor Bahadur Shah Zafar. His leadership was characterized by a concerted effort to unify different sections of society against colonial rule. He maintained his authority in Rohilkhand for about a year, providing stiff resistance to the British forces. After the eventual capture of Bareilly by the British in May 1858, he fled to Nepal but was later apprehended, tried for treason, and executed in Bareilly in 1860.

Explanation

Article 20 of the Constitution of India provides three specific protections to individuals in respect of conviction for offences: protection against ex-post facto laws under Clause 1, protection against double jeopardy under Clause 2, and protection against self-incrimination under Clause 3. The prohibition against torture is not explicitly mentioned within the text of Article 20. Instead, the right against torture and custodial violence is recognized as a fundamental right derived from the protection of life and personal liberty under Article 21, as established by the Supreme Court through various landmark judgments.

Explanation

Article 76 of the Constitution of India defines the office and appointment of the Attorney General. According to Article 76(1), the President shall appoint a person who is qualified to be appointed a Judge of the Supreme Court to be Attorney General for India. The qualifications for a Supreme Court judge include being a citizen of India and having been a judge of a High Court for five years, or an advocate of a High Court for ten years, or being an eminent jurist in the opinion of the President.

Regarding the removal process, Article 76(4) specifies that the Attorney General holds office during the pleasure of the President. This means the President can remove the Attorney General at any time without following the specialized procedure prescribed for Supreme Court judges. While Supreme Court judges can only be removed by the President following an address by Parliament on the grounds of proved misbehaviour or incapacity under Article 124(4), the Constitution does not provide any such protection or specific procedure for the Attorney General.

Explanation

The National Population Policy 2000 originally established the long-term objective of achieving a stable population for India by the year 2045. This target was intended to reach a level consistent with the requirements of sustainable economic growth and environmental protection. However, due to demographic momentum and the time required for all states to reach replacement-level fertility, the government subsequently revised this target. The current target for population stabilization is fixed at the year 2070. This stabilization phase occurs when the birth and death rates reach equilibrium, resulting in a zero population growth rate, typically following several decades of maintaining replacement-level fertility.

Explanation

The Ninth Schedule of the Constitution of India contains a list of central and state laws that are protected from judicial review under Article 31B, primarily relating to land reforms and the abolition of the Zamindari system. The allocation of seats in the Council of States (Rajya Sabha) to the States and Union Territories is actually dealt with under the Fourth Schedule. The Ninth Schedule was added to the Constitution by the First Amendment Act of 1951 to prevent legal challenges against socialist economic reforms.

Explanation

Natural silk is a fibrous protein produced by certain insect larvae, primarily the silkworm. As a protein-based material, it is composed of long chains of amino acids. The fundamental chemical structure of any amino acid includes an amino group (-NH₂), which contains nitrogen. The specific proteins that make up silk, known as fibroin and sericin, are primarily composed of amino acids such as glycine, alanine, and serine. Because nitrogen is a core element in the molecular structure of all proteins, it is a primary constituent of natural silk.

Explanation

Nadhim Zahawi was dismissed from his position as Conservative Party Chairman and Minister without Portfolio following an investigation by Sir Laurie Magnus, the Prime Minister's independent ethics adviser. The inquiry concluded that Zahawi had committed a serious breach of the Ministerial Code by failing to be transparent about a tax dispute and subsequent settlement with HM Revenue and Customs (HMRC). The settlement, which included a penalty, concerned the sale of shares in the polling firm YouGov, a company Zahawi co-founded. By failing to disclose the nature of this investigation and the penalty paid while he was being appointed to senior government roles, including his time as Chancellor of the Exchequer, he was found to have fallen short of the standards of integrity and transparency required of ministers.

Explanation

Explanation

Mount Newman, situated in the Pilbara region of Western Australia, is globally renowned for its massive deposits of high-grade iron ore. It serves as a major mining hub, most notably for the Mount Whaleback mine, which is recognized as one of the largest open-cut iron ore mines in the world. The development of the Mount Newman project in the late 1960s was instrumental in establishing the Pilbara as a premier iron-producing province. The ore mined here consists primarily of high-quality hematite, which is essential for global steel production. Large-scale operations in this area involve transporting the extracted ore through dedicated heavy-haul rail networks to Port Hedland for international export, making it a cornerstone of the global mineral trade.

Explanation

Economic activities are defined as human actions performed with the objective of earning money, generating income, or creating wealth through the production and exchange of goods and services. Voluntary social service is classified as a non-economic activity because it is motivated by selfless concern for the well-being of others, social obligation, or personal psychological satisfaction rather than financial remuneration. Since these services are provided without the expectation of profit or a salary, they do not satisfy the criteria of an economic transaction in a formal market framework.

Explanation

The Vishnu Purana is one of the eighteen Mahapuranas and serves as a significant historical source for the Mauryan dynasty, as it contains genealogical lists of the Mauryan kings and describes the end of the Nanda dynasty. Similarly, the Vayu Purana provides valuable insights into the Gupta empire, specifically detailing the geography and the extent of the territories ruled by the early Gupta monarchs. These texts are essential literary sources used by historians to reconstruct the political history, lineage, and administrative influence of these prominent ancient Indian dynasties.

Explanation

The Shyama Prasad Mukherji Rurban Mission (SPMRM) was officially launched by the Government of India on February 21, 2016. The scheme was inaugurated by Prime Minister Narendra Modi at Kurubhat, Rajnandgaon, Chhattisgarh, with the objective of developing 300 Rurban clusters across the country to trigger local economic development and bridge the rural-urban divide. Although the Union Cabinet approved the mission in September 2015, the official launch and implementation year recognized in government documentation and administrative records is 2016.

Explanation

Sustainable development is defined as development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs. This principle specifically addresses the management of natural resources by striking a balance between immediate human requirements for economic and social growth and the necessity of preserving the environment and its assets for the long term. It emerged as a core global objective following the 1987 Brundtland Report, emphasizing that resource utilization must be conducted at a rate that allows for replenishment and ecological stability, ensuring that future populations have access to the same essential resources available today.

Explanation

Article 32 of the Constitution of India, known as the Right to Constitutional Remedies, provides the mechanism for the enforcement of Fundamental Rights. Under Article 32(2), the Supreme Court is specifically empowered to issue directions, orders, or writs, including Habeas Corpus, Mandamus, Prohibition, Quo Warranto, and Certiorari, for the enforcement of any of the rights conferred by Part III. This establishes the Supreme Court as the protector and guarantor of Fundamental Rights. Furthermore, Article 32(3) grants Parliament the legislative authority to empower any other court to exercise within its local jurisdiction the powers exercisable by the Supreme Court under clause (2). While High Courts possess writ jurisdiction under Article 226, this constitutional provision allows for the potential expansion of such powers to subordinate courts if Parliament deems it necessary through legislation.

Explanation

The Ramganga river originates in the Doodhatoli range of the Pauri Garhwal district in Uttarakhand. It flows through the Jim Corbett National Park and enters the Indo-Gangetic plains near Kalagarh. It follows a south-easterly course and joins the Ganga river on its left bank near the city of Kannauj in Uttar Pradesh. The Betwa river, which is a major tributary of the Yamuna, originates in the Vindhya Range in the Raisen district of Madhya Pradesh. It flows in a north-easterly direction through Madhya Pradesh and Uttar Pradesh before merging with the Yamuna river near Hamirpur. The city of Prayagraj is the site of the Triveni Sangam, which marks the confluence of the Ganga and Yamuna rivers.

Explanation

The sequence of foreign invasions in ancient India began with the Greeks, specifically the Indo-Greeks, who established themselves in the northwestern region in the early 2nd century BCE around 180 BCE under leaders like Demetrius I. They were followed by the Sakas, also known as Indo-Scythians, who migrated from Central Asia into the Indian subcontinent during the 1st century BCE, displacing Greek rule in regions like Gandhara and Taxila. Subsequently, the Kushans, who were a branch of the Yuezhi nomadic tribes from Central Asia, entered India in the 1st century CE. Kujula Kadphises founded the Kushan dynasty, which eventually reached its zenith under the reign of Kanishka in the 2nd century CE. This progression from the 2nd century BCE to the 1st century CE establishes the historical timeline of these groups.

Explanation

The Chamber of Princes, also known as the Narendra Mandal, was established following the recommendations of the Montagu-Chelmsford Reforms, which were enacted through the Government of India Act 1919. This consultative and advisory body was formally inaugurated by a Royal Proclamation in 1921 to provide a forum for the rulers of the princely states to discuss matters of common interest and their relationship with the British Crown. It comprised 120 members, including 108 rulers of the more significant states who were members in their own right, and 12 members elected by the rulers of 127 other states. The chamber played a crucial role in representing the interests of the princely states in the constitutional developments of colonial India.

Explanation

The beta cells located within the Islets of Langerhans of the pancreas are responsible for the synthesis and secretion of insulin. Insulin is a vital peptide hormone that regulates carbohydrate and fat metabolism in the body. It primarily functions to lower blood glucose levels by facilitating the uptake of glucose into systemic cells, particularly skeletal muscle and adipose tissue, and by promoting glycogenesis in the liver. These cells monitor blood sugar concentrations and release insulin in response to hyperglycemia to maintain glucose homeostasis.

Explanation

Actinium is a radioactive metallic chemical element with the symbol Ac and atomic number 89. It belongs to Group 3 of the periodic table and is the first element of the actinide series, rather than being a member of the Group 18 Noble gases. While Noble gases are characterized by their extreme chemical stability and gaseous state at room temperature due to their complete valence electron shells, actinium is a silver-white metal that is highly reactive and radioactive. It occurs naturally in trace amounts in uranium ores and is primarily known for its role as the namesake for the series of fifteen metallic elements between actinium and lawrencium.

Explanation

Pope Benedict XVI, born Joseph Ratzinger in Marktl, Bavaria, was a native of Germany and the first German to lead the Catholic Church in centuries. He served as Pope from 2005 until his retirement in February 2013. His resignation was a historic milestone because he was the first pontiff to voluntarily step down from the papacy since Pope Gregory XII in 1415, a period spanning nearly 600 years. Benedict XVI cited his advanced age and declining physical and mental strength as the primary reasons for his departure, after which he assumed the title of Pope Emeritus until his death in December 2022.

Explanation

Habitat destruction is the primary driver of biodiversity loss globally because it fundamentally removes the living space and resources necessary for the survival of species. When natural ecosystems such as forests, wetlands, and grasslands are converted for agriculture, urbanization, or industrial infrastructure, the resident flora and fauna lose their sources of food, shelter, and reproductive sites. This process leads to immediate population declines and increased extinction rates. Beyond direct loss, it also results in habitat fragmentation, where large, continuous habitats are broken into smaller, isolated patches, making species more vulnerable to environmental shifts and reducing their genetic diversity through restricted movement. International conservation bodies, including the IUCN and IPBES, identify land-use change and the resulting destruction of natural habitats as the most significant factor contributing to the current global biodiversity crisis.

Explanation

Xylem is a specialized vascular tissue in plants primarily responsible for the conduction of water and dissolved minerals from the roots to the aerial parts of the plant, such as stems and leaves. This transport mechanism is largely driven by transpiration pull and root pressure, facilitating a unidirectional upward flow. The functional components of xylem, primarily tracheids and vessel elements, are elongated cells that lose their protoplasm at maturity, forming hollow tubes that allow for the efficient bulk movement of water throughout the plant structure. These cells also have lignified walls, which provide necessary mechanical support to the plant.

Explanation

The Sudarshan Prahar exercise was conducted by the Sudarshan Chakra Corps of the Indian Army Southern Command in the desert sectors of Rajasthan in December 2022. The primary objective of this exercise was to validate the integration of force multipliers and practice high-intensity combat operations. It focused on the synergy between different arms of the military, including the application of new-age technologies and weapon systems to ensure seamless coordination in a battlefield environment. The exercise demonstrated the Indian Army combat readiness and its ability to execute synchronized operations in challenging desert terrain.

Explanation

The Spanish and Americans played pivotal roles in transforming the Philippines into a major producer of coconut and sugarcane by shifting the economy toward large-scale export agriculture. During the Spanish colonial era, the introduction of the hacienda system and the opening of the country to world trade in the 19th century incentivized the mass cultivation of sugarcane, particularly in the Visayas region. When the United States took control in 1898, they further accelerated this development through trade policies like the Payne-Aldrich Tariff Act of 1909, which provided Philippine sugar and coconut products duty-free access to the vast American market. The American administration also introduced scientific farming methods, improved irrigation, and modernized processing mills, establishing the Philippines as a global leader in the production of copra and centrifugal sugar.

Explanation

The Yamuna river originates from the Yamunotri glacier located on the Banderpunch peaks in the Garhwal Himalayas of Uttarakhand. The Krishna river rises in the Western Ghats near the town of Mahabaleshwar in Maharashtra at an elevation of approximately 1,337 meters. The Godavari river, the largest peninsular river, has its source at Trimbakeshwar in the Nasik district of Maharashtra within the Western Ghats range. The Mahanadi river originates from the highlands of Chhattisgarh near the village of Sihawa in the Dhamtari district. Matching these pairs leads to the sequence A-4, B-3, C-2, and D-1.

Explanation

Mount Kilimanjaro is a dormant volcano located in Tanzania and is recognized as the highest peak in Africa. Mount Toubkal is the highest point in the Atlas Mountains and is situated in southwestern Morocco. Mount Stanley represents the highest peak of the Rwenzori Mountains, positioned on the border between Uganda and the Democratic Republic of the Congo. The Hoggar Mountains, also known as the Ahaggar, are a highland region in the central Sahara located in southern Algeria. These geographical features correctly pair as A-3, B-1, C-4, and D-2.

Explanation

Lake Onega is located in the northwestern part of Russia, specifically within the Republic of Karelia, Vologda Oblast, and Leningrad Oblast. It is the second-largest lake in Europe after Lake Ladoga and is a vital part of the internal waterways of the Russian Federation, connecting to the Baltic Sea via the Svir River and to the White Sea through the White Sea-Baltic Canal. Since the lake is situated entirely within Russian territory, the pairing with Canada is geographically incorrect.

Explanation

Bimal Jalan, a former Governor of the Reserve Bank of India, authored the book titled From Dependence to Self-Reliance: Mapping India's Rise as a Global Superpower. Published in 2022, the book examines India's economic trajectory from the 1991 liberalization period to the contemporary era. It focuses on the country's transition from an economy reliant on external aid and imports to one aiming for self-sufficiency and global leadership. Jalan provides insights into necessary policy reforms and administrative changes required to overcome structural bottlenecks, emphasizing the importance of institutional integrity and effective governance in securing India's future growth.

Explanation

The representation of states in the Indian Parliament is determined primarily by their population. As the most populous state in India, Uttar Pradesh is allotted the highest number of seats in both houses. According to the Fourth Schedule of the Constitution of India, Uttar Pradesh has 31 seats in the Rajya Sabha. For the Lok Sabha, the state is divided into 80 parliamentary constituencies, making it the largest contributor of members to the lower house. These seat allocations have remained constant based on the 1971 census figures, following the provisions of the 84th Constitutional Amendment Act, which froze the number of seats in the Parliament until the results of the first census after 2026 are published.

Explanation

Captain William Hawkins was an English sea captain and representative of the British East India Company who arrived at the court of the Mughal Emperor Jahangir in April 1609. He was exceptionally well-versed in the Turkish language, a skill he had acquired during his extensive travels and service in the Levant. This proficiency proved to be a major diplomatic asset, as it allowed him to communicate directly with Jahangir in the Emperor's ancestral tongue without the mediation of interpreters. Jahangir was greatly impressed by Hawkins' linguistic abilities and his knowledge of the world, leading to a close personal rapport. Consequently, the Emperor honored him with the title of English Khan and appointed him as a Mansabdar with a rank of 400, marking a significant moment in early Anglo-Mughal relations.

Explanation

Janani Suraksha Yojana (JSY) is a safe motherhood intervention implemented under the National Rural Health Mission (NRHM) since April 2005. The scheme aims to reduce maternal and neonatal mortality by promoting institutional delivery among poor pregnant women, particularly those belonging to the Scheduled Castes, Scheduled Tribes, and Below Poverty Line (BPL) households. By providing direct cash assistance to eligible women for giving birth in government or accredited private health facilities, the program ensures access to skilled birth attendance and emergency obstetric care. This strategy directly addresses the primary causes of death during childbirth and the immediate postnatal period for both mothers and newborns.

Explanation

Under Article 124(2)(a) of the Constitution of India, a Judge of the Supreme Court may resign from their office by submitting a written letter under their hand addressed to the President. As the President is the appointing authority for Judges of the Supreme Court, the formal resignation must be directed to the head of the executive to take legal effect. This constitutional procedure ensures that the vacancy is officially recognized by the authority responsible for initiating the process of a new appointment.

Explanation

According to Article 280(1) of the Constitution of India, the Finance Commission consists of a Chairman and four other members, making a total of five members. The Finance Commission (Miscellaneous Provisions) Act, 1951, further specifies the qualifications and selection process for these members. Additionally, under Article 281, the Finance Commission is required to submit its report and recommendations directly to the President of India. The President then causes the report, along with an explanatory memorandum on the actions taken, to be laid before both Houses of Parliament. The Commission does not submit its report to the NITI Aayog, which is a non-constitutional policy think tank.

Explanation

The Hangul, also known as the Kashmir Stag (Cervus hanglu hanglu), is a subspecies of Central Asian Red Deer endemic to India. It is primarily found in the high-altitude temperate forests and riverine grasslands of the Kashmir Valley in Jammu and Kashmir. Its most significant and last remaining viable population resides within the Dachigam National Park, located near Srinagar. Recognized for its majestic multi-tined antlers, the Hangul is the state animal of Jammu and Kashmir and is categorized as Critically Endangered on the IUCN Red List due to habitat fragmentation and population decline.

Explanation

Article 171 of the Constitution of India defines the composition and strength of the State Legislative Council. According to Clause 1 of this Article, the total number of members in the Legislative Council of a state must not exceed one-third of the total number of members in the Legislative Assembly of that state. This ensures that the upper house remains a secondary body relative to the popularly elected lower house. Furthermore, the same clause provides a statutory minimum, stating that the total membership shall in no case be less than forty members. These constitutional limits are designed to maintain institutional balance and ensure the functional viability of the state legislature.

Explanation

Tappa is a semi-classical form of Hindustani vocal music characterized by its fast, subtle, and knotty construction with quick, bouncy taans. It originated from the folk songs of camel drivers in the Punjab and North-West frontier regions. This musical style was refined and brought into the royal fold during the reign of the Mughal Emperor Muhammad Shah, who was a prolific patron of music and the arts. The transformation of Tappa from a rustic folk melody into a sophisticated courtly genre is primarily attributed to Mian Ghulam Nabi Shori, also known as Shori Mian, who was a celebrated musician in the court of Muhammad Shah. Under the Emperor's patronage, the style gained classical status, blending the rhythmic vitality of folk music with the technical complexity required for courtly performances.

Explanation

Article 71(2) of the Constitution of India stipulates that if the election of a person as Vice-President is declared void by the Supreme Court, acts done by him in the exercise and performance of the powers and duties of the office on or before the date of the decision of the Supreme Court shall not be invalidated by reason of that declaration. This constitutional provision ensures administrative stability and prevents a legal vacuum regarding the decisions made during the individual's tenure. Since the protection explicitly covers the period up to and including the date of the judicial decision, all official acts performed by the Vice-President before the ruling are valid. Furthermore, the inclusion of the phrase on or before the date of the decision means that acts performed on the actual day the declaration is made also remain legally valid, contradicting any claim that acts on that day are void.

Explanation

Nevasa (A-3) is located on the Pravara River in the Ahmednagar district of Maharashtra and is the type-site for the Middle Palaeolithic Nevasan culture characterized by flake tools. Isampur (B-4) is situated in the Hunsgi-Baichbal valley in Karnataka and is recognized as a major Lower Palaeolithic Acheulian quarry and workshop site. Didwana (C-1) is located in the Nagaur district of Rajasthan where the 16R dune has yielded a long chronological sequence of Palaeolithic tools and environmental data. Gudiyam cave (D-2) is a significant Lower Palaeolithic rock shelter site located in the Thiruvallur district of Tamil Nadu near the Allikulli hills.

Explanation

India held the presidency of the Shanghai Cooperation Organisation (SCO) from September 2022 to September 2023. Under this leadership, the Ministry of Information and Broadcasting organized the SCO Film Festival in Mumbai from January 27 to 31, 2023. The festival was designed to showcase the cinematic diversity of the SCO region, featuring films specifically from SCO member states, observer states, and dialogue partners. The event served as a platform for cultural exchange and aimed to strengthen people-to-people ties through the medium of cinema, aligning with India's theme for its SCO presidency, SECURE SCO.

Explanation

Laterite soil is formed in tropical and subtropical regions characterized by high temperatures and heavy seasonal rainfall. Under these climatic conditions, intense leaching occurs, where heavy rains wash away soluble silica and lime from the soil profile. This process leaves behind a residue that is highly enriched in iron oxide and aluminium, which gives the soil its characteristic reddish color and allows it to harden like a brick when dry. Consequently, statement 1 is factually accurate regarding its formation environment, while statement 2 is incorrect because the soil is inherently rich in iron and aluminium rather than being poor in them.

Explanation

Tribunals are covered under Part XIV-A of the Indian Constitution, which was inserted by the 42nd Amendment Act of 1976. This specific part includes Article 323A, which deals with administrative tribunals, and Article 323B, which deals with tribunals for other matters such as taxation, foreign exchange, and land reforms. Conversely, Part XI of the Constitution is dedicated to the Relations between the Union and the States, encompassing legislative relations from Articles 245 to 255 and administrative relations from Articles 256 to 263. Therefore, the association of Tribunals with Part XI is fundamentally incorrect.

Explanation

The Great Sandy Desert, located in northwestern Australia, is the smallest among the choices with an area of approximately 284,993 km². The Gobi Desert, a large cold desert region in North China and Southern Mongolia, follows with an area of about 1,295,000 km². The Arabian Desert, which covers nearly the entire Arabian Peninsula in Western Asia, is significantly larger at approximately 2,330,000 km². The Sahara Desert in North Africa is the largest on the list and the largest hot desert in the world, spanning roughly 9,200,000 km². Consequently, the deserts arranged in increasing order of size are the Great Sandy (I), Gobi (IV), Arabian (II), and Sahara (III).

Explanation

The Social Progress Index (SPI) for States and Districts of India was released in December 2022 by the Economic Advisory Council to the Prime Minister (EAC-PM). The index evaluates states and Union Territories based on 89 indicators across three dimensions: Basic Human Needs, Foundations of Wellbeing, and Opportunity. Based on the SPI scores, regions were classified into six tiers. In Tier-1, which denotes Very High Social Progress, Puducherry emerged as the top-ranking region with an SPI score of 65.99. Lakshadweep followed in the second position with a score of 65.89, and Goa secured the third position with a score of 65.53. These three entities demonstrated the highest performance in parameters such as personal safety, access to basic medical care, and personal rights within the Indian context for that period.

Explanation

The United Nations Secretary General produces an annual Sustainable Development Goals Progress Report to track the implementation of the 2030 Agenda. This report is prepared in collaboration with the United Nations system and is based on the global indicator framework developed by the Inter-agency and Expert Group on SDG Indicators. It utilizes data provided by National Statistical Systems and information gathered at the regional level to ensure a comprehensive global overview. Conversely, the Global Sustainable Development Report (GSDR) is a distinct, science-based document authored by an independent group of scientists. According to the mandate established at the High-Level Political Forum, the GSDR is produced once every four years, not every quarter, to inform the quadrennial deliberations of the United Nations General Assembly.

Explanation

According to Article 79 of the Constitution of India, the Parliament of the Union consists of the President and the two Houses, namely the Council of States (Rajya Sabha) and the House of the People (Lok Sabha). Although the President is not a member of either House and does not sit in the Parliament to attend its meetings, they are an integral part of it because of their legislative functions. Under Article 111, a bill passed by both Houses of Parliament cannot become a law or an Act until it receives the assent of the President. Since the primary function of the Parliament is law-making and this process remains incomplete without the President's signature, the Reason correctly explains why the President is considered a constituent part of the Parliament.

Explanation

The Mopla Rebellion, or Malabar Rebellion, occurred in August 1921 in the Malabar region of Kerala. It was an armed uprising by the Mappila Muslim peasantry against the British colonial authorities and the local landlord system. This event occurred after the Home Rule Movement of 1916, the Jallianwala Bagh Massacre of April 1919, and the launch of the Khilafat Movement later in 1919. The revolt continued through much of 1921 before being suppressed by the British administration.

Explanation

Pesticides are synthetic chemical compounds, such as organochlorines like DDT, that are designed to be stable and persistent to effectively control pests over time. These substances possess complex molecular structures that natural decomposers, such as bacteria and fungi, cannot easily break down through biological processes. Because they resist degradation by microorganisms, pesticides remain in the ecosystem for long periods, often leading to bioaccumulation and biomagnification within the food chain. This persistence categorizes them as non-biodegradable pollutants, distinguishing them from organic wastes that are readily decomposed by natural microbial action.

Explanation

Agenda 21 is a non-binding, voluntarily implemented action plan of the United Nations with regard to sustainable development. It was a primary outcome of the Earth Summit, formally known as the United Nations Conference on Environment and Development (UNCED), held in Rio de Janeiro, Brazil, in 1992. The number 21 refers to the 21st century, representing a comprehensive blueprint for action to be taken globally, nationally, and locally by organizations of the UN system, governments, and major groups. The agenda addresses critical challenges including poverty, hunger, health, and the protection of the atmosphere, oceans, and biodiversity, all aimed at achieving a balance between economic growth and environmental preservation for future generations.

Explanation

Xerocoles are animals that are biologically adapted to live in the desert. The name is derived from the Greek word xeros, which means dry, and the Latin word colere, meaning to inhabit. These animals have evolved specific physiological and behavioral traits to survive in arid regions characterized by extreme temperatures and limited water availability. Common adaptations include being nocturnal to avoid the intense heat of the day, having the ability to extract water from their food, and possessing specialized kidneys that produce highly concentrated urine to minimize water loss from the body.

Explanation

Devprayag is the site of the holy confluence where the Alaknanda river meets the Bhagirathi river in the Tehri Garhwal district of Uttarakhand. This location is of immense religious significance as it marks the point where the two rivers merge to officially form the Ganga river. The Bhagirathi originates from the Gaumukh at the Gangotri glacier and is traditionally regarded as the primary source of the Ganga, while the Alaknanda originates from the Satopanth glacier. Devprayag is the last of the Panch Prayag, the five sacred river confluences in the Garhwal Himalayas.

Explanation

Seaweeds, particularly brown algae such as kelp and Laminaria, are well-known for their unique ability to concentrate iodine from seawater at levels up to 30,000 times the concentration found in the surrounding environment. They utilize specialized transport mechanisms and enzymes like vanadium-dependent haloperoxidases to sequester iodine, which serves as an inorganic antioxidant to protect the plant against oxidative stress during low tide or environmental changes. Historically, seaweeds were the primary commercial source for the extraction of iodine before mineral deposits were discovered. In modern nutrition, seaweeds remain one of the most concentrated natural dietary sources of this essential trace element, which is critical for the synthesis of thyroid hormones in humans.

Explanation

Under Article 243A of the Constitution of India, a Gram Sabha may exercise such powers and perform such functions at the village level as the Legislature of a State may, by law, provide. The 73rd Constitutional Amendment Act, 1992, which constitutionalized the Panchayati Raj institutions, explicitly delegates the authority to define the scope and authority of the Gram Sabha to the respective state governments. Consequently, the powers and functions of the Gram Sabha are determined by state-level legislation rather than by the Central Government. This ensures that the local governance framework can be tailored to the specific needs and administrative structures of each state.

Explanation

Lotic ecosystems are freshwater habitats characterized by actively flowing or moving water. The term is derived from the Latin word lotus, meaning washed, which signifies the continuous motion of the water body. Rivers and streams are the primary examples of lotic systems because their water travels in a unidirectional path along a geographic gradient. These environments are defined by their dynamic nature, high levels of dissolved oxygen resulting from constant aeration at the surface, and specialized biota that have evolved various adaptations to maintain their position within the current.

Explanation

The Rani of Jhansi Regiment was established in July 1943 as the all-female combat unit of the Indian National Army (Azad Hind Fauj) under the leadership of Netaji Subhash Chandra Bose. Named after the legendary heroine of the 1857 Indian Rebellion, Rani Lakshmi Bai, it was one of the first female infantry units in modern military history. The regiment was led by Captain Lakshmi Sahgal and consisted of female volunteers from the Indian diaspora in Southeast Asia, particularly from Malaya, Singapore, and Burma. These women underwent rigorous military training, including weapon handling and tactical drills, as part of Netaji's vision to involve all sections of Indian society in the armed struggle for independence from British rule.

Explanation

Situated on the banks of the Hindon River, which is a tributary of the Yamuna, this site represents the expansion of the Harappan culture into the Ganga-Yamuna Doab region. Excavations at this site have revealed characteristic Harappan pottery, terracotta cakes, and beads, confirming its status as a vital settlement at the edge of the civilization's geographical extent during its mature phase.

Explanation

The PM Gati Shakti - National Master Plan for Multi-modal Connectivity was launched on October 13, 2021, rather than 2022. It is a digital platform designed to bring 16 Ministries together for integrated planning and coordinated implementation of infrastructure connectivity projects. The scope of PM Gati Shakti encompasses the seven engines of economic growth: Roads, Railways, Airports, Ports, Mass Transport, Waterways, and Logistics Infrastructure. These engines work in unison to pull the economy forward by improving productivity and global competitiveness. Additionally, the Union Budget 2022-23 mandated that the National Infrastructure Pipeline (NIP) for these seven engines be aligned with the PM Gati Shakti framework to facilitate seamless multimodal connectivity and enhance the ease of living and doing business.

Explanation

The Mid-day Meal Scheme was officially renamed as the PM POSHAN (Pradhan Mantri Poshan Shakti Nirman) Scheme in September 2021 following approval by the Cabinet Committee on Economic Affairs. This transition was part of a broader initiative to enhance the nutritional outcomes for school-going children and align the program with the goals of the National Education Policy 2020. Under the new nomenclature, the scheme was extended to cover children in pre-primary classes or Balvatikas in addition to those in classes 1 to 8 of government and government-aided schools. The revamped scheme emphasizes a holistic approach to nutrition, involving local communities, social audits, and the promotion of nutritional gardens to supplement the daily meals provided to millions of students nationwide.

Explanation

El Nino is a periodic climatic phenomenon characterized by the warming of sea surface temperatures in the central and eastern equatorial Pacific. During an El Nino event, the prevailing trade winds weaken, which allows warm water from the western Pacific to flow eastward toward the South American coast. This results in the appearance of a warm surface current that replaces the cold, nutrient-rich Humboldt Current off the coast of Peru.

While this phenomenon causes a rise in water temperature, its primary ecological effect is the suppression of upwelling. Upwelling normally brings cold, nutrient-dense water from the deep ocean to the surface, which fuels the growth of phytoplankton. The presence of the warm El Nino layer prevents this vertical mixing, leading to a drastic reduction in the nutrient supply. As a result, the amount of plankton in the sea decreases significantly, which negatively impacts the marine food web and local fisheries. This confirms that while the first statement is an accurate description of the physical process, the second statement is incorrect regarding the biological consequences.

Explanation

Shivanasamudra, located in the Mandya district of Karnataka, is situated on the banks of the river Kaveri. It is historically significant as the site of one of Asia's first major hydroelectric power stations, which was commissioned in 1902 to supply electricity to the Kolar Gold Fields. This project marked a pioneering step in hydel power generation in India. Kalpakkam, situated on the Coromandel Coast in Tamil Nadu, is a premier center for nuclear energy. It is home to the Madras Atomic Power Station (MAPS), which was India's first fully indigenous nuclear power plant. The location also houses the Indira Gandhi Centre for Atomic Research (IGCAR), which focuses on the development of fast breeder reactor technology, making it a critical component of India's nuclear energy infrastructure.

Explanation

The National Centre for Marine Biodiversity (NCMB) is India's first research institute dedicated exclusively to the study and conservation of marine biological resources. It is located in Jamnagar, Gujarat. The centre was established through a Public-Private Partnership (PPP) model involving the Ministry of Environment, Forest and Climate Change and Reliance Industries Limited. Jamnagar was selected as the site because of its strategic proximity to the Marine National Park in the Gulf of Kutch, which was the first marine national park established in India. The NCMB functions as a part of the Integrated Coastal Zone Management (ICZM) project, focusing on creating a comprehensive database of marine species, conducting advanced research, and developing strategies for the sustainable management of India's coastal and marine ecosystems.

Explanation

Hamida Banu Begum was the wife of the second Mughal Emperor, Humayun, and the mother of Emperor Akbar. She married Humayun in 1541 AD and was later known by the title Maryam Makani. Alauddin Khilji was a powerful ruler of the Khilji dynasty of the Delhi Sultanate who reigned from 1296 to 1316 AD. Because Hamida Banu Begum was a 16th-century Mughal consort and Alauddin Khilji was a late 13th-century Sultan, they belong to entirely different historical periods and dynasties.

Explanation

In-situ conservation involves the protection of flora and fauna within their natural surroundings. National Parks are designated areas where entire ecosystems, along with the genetic diversity of the species inhabiting them, are preserved in their original environment. This method ensures that natural evolutionary processes and ecological interactions continue uninterrupted, which is essential for maintaining the genetic health and resilience of wildlife populations over time. By protecting the habitat itself, in-situ conservation allows species to adapt to environmental changes naturally.

Explanation

In the administrative structure of medieval Indian states, particularly within the Maratha Empire and Rajput kingdoms influenced by Persian terminology, the Khareetadar was an official responsible for the dispatch and management of royal communications. The term is derived from khareeta, which refers to the silk or leather pouch used to carry important letters, treaties, or royal decrees sent between rulers or high-ranking officials. The Khareetadar ensured that these documents were properly prepared, protected in their ceremonial bags, and delivered through the state communication network, essentially serving as the custodian and dispatcher of formal state correspondence.

Explanation

Biological Oxygen Demand (BOD) is the amount of dissolved oxygen required by aerobic microorganisms to decompose the organic matter present in a given water sample at a specific temperature over a set period. It is a critical parameter used to measure the level of organic pollution in aquatic ecosystems. When water bodies are contaminated with sewage, agricultural runoff, or industrial waste, the concentration of organic matter increases, leading to a higher rate of microbial decomposition. This process consumes significant amounts of dissolved oxygen, resulting in a high BOD value. Therefore, BOD serves as an essential indicator of water quality, where higher values signify greater pollution and a potential depletion of oxygen available for fish and other aquatic organisms.

Explanation

The Tamil Nadu coast remains relatively dry during the South-West monsoon season due to its specific geographical orientation and the influence of the Western Ghats. As the Arabian Sea branch of the South-West monsoon strikes the Western Ghats, it releases most of its moisture on the windward side, leaving the state of Tamil Nadu on the leeward side in a significant rain shadow region. Furthermore, the Bay of Bengal branch of the monsoon moves parallel to the Coromandel Coast, which prevents the moisture-laden winds from being forced upward by any topographical barriers to produce precipitation. Because these winds do not blow directly onto the land but rather alongside it, the necessary orographic lift for rainfall is absent. These two factors combined ensure that the region receives minimal rainfall during the summer monsoon months, instead getting the majority of its annual precipitation during the North-East monsoon season.

Explanation

Article 118(4) of the Constitution of India stipulates that the Speaker of the Lok Sabha presides over a joint sitting of both Houses of Parliament. In the Speaker's absence, the Deputy Speaker of the Lok Sabha presides, followed by the Deputy Chairman of the Rajya Sabha if the Deputy Speaker is also absent. While the joint sitting itself is provided for under Article 108 to resolve deadlocks between the Houses, Article 109 concerns the special procedure for Money Bills, which cannot be referred to a joint sitting.

Spanning approximately 594 kilometers, it is a six-lane greenfield expressway designed to connect Meerut in western Uttar Pradesh with Prayagraj in the eastern part of the state. The project is a state-level initiative aimed at enhancing regional connectivity, reducing travel time between major cities, and fostering industrial and economic growth across twelve districts. Since the planning, financing, and execution are handled entirely by the state authorities, it is classified as a state government programme.

Explanation

Sustainable development is an approach to growth and resource management that prioritizes meeting the needs of the present population without compromising the ability of future generations to meet their own needs. This concept, popularized by the Brundtland Commission in its 1987 report Our Common Future, emphasizes the responsible use of natural resources to ensure they are not depleted or degraded beyond recovery. It involves maintaining a balance between economic progress, social well-being, and environmental conservation, ensuring that the natural capital of the planet remains intact and functional for the long term.

Explanation

Shanti Ghosh was a revolutionary nationalist from Bengal who was active during the early 1930s. She is primarily known for her role in the assassination of Charles Stevens, the British District Magistrate of Comilla, on 14 December 1931, an act she carried out alongside Suniti Chowdhury. This event occurred more than a decade before the launch of the Quit India Movement in August 1942. Her contribution to the freedom struggle was defined by the armed revolutionary phase of the 1930s, and she was not a participant in the mass civil disobedience movement of 1942.

Explanation

The protection and improvement of the environment is a shared constitutional mandate found in both Part IV and Part IV-A of the Constitution of India. Article 48A, under the Directive Principles of State Policy, directs the State to endeavour to protect and improve the environment and to safeguard the forests and wildlife of the country. Complementing this, Article 51A(g) establishes a Fundamental Duty for every citizen of India to protect and improve the natural environment including forests, lakes, rivers, and wildlife, and to have compassion for living creatures. Both of these provisions were incorporated into the Constitution via the 42nd Constitutional Amendment Act of 1976 to ensure a collective responsibility between the government and the citizenry toward ecological preservation.

Explanation

Igarka is a port city located in the Krasnoyarsk Krai region of Russia, situated on the Yenisei River within the Arctic Circle. It is a major timber-exporting port and serves as a key industrial center in the Russian Siberia region, rather than being located in China. The port is accessible to deep-draft vessels from the Kara Sea, facilitating the transport of natural resources from the Siberian interior to international markets.

Explanation

Article 343 of the Constitution of India defines the official language of the Union. Under Article 343(1), Hindi in Devanagari script was declared the official language. However, to facilitate a smooth transition from the colonial administrative setup, Article 343(2) provided that for a period of fifteen years from the commencement of the Constitution on January 26, 1950, the English language would continue to be used for all official purposes of the Union for which it was being used immediately before such commencement. This period was set to expire on January 25, 1965. Article 343(3) further empowered Parliament to pass legislation to extend the use of English beyond this initial fifteen-year duration, which eventually led to the enactment of the Official Languages Act of 1963.

Explanation

The Anuthee Uphar Scheme, or Unique Gift Scheme, was launched by the Government of Uttar Pradesh in April 2021 to incentivize and accelerate the COVID-19 vaccination drive across the state. Under this initiative, the state health department organized lucky draws for citizens who had received their vaccine doses. Districts were encouraged to meet specific vaccination targets, and participants from districts with high coverage were eligible to win various prizes through a lottery system. The primary objective of the scheme was to create public awareness, mitigate vaccine hesitancy, and ensure a rapid immunization process to combat the pandemic within the various administrative divisions of Uttar Pradesh.

Explanation

The sanctuary lies on the northern slopes of the Kaimur Range, which is part of the Vindhyan hill system, and spans an area of approximately 78 square kilometers. It gained historical prominence as a site for an Asiatic lion reintroduction program in the late 1950s. The landscape is characterized by dense forests and the presence of the scenic Rajdari and Devdari waterfalls. It serves as a natural habitat for a variety of species, including leopards, hyenas, wild boars, nilgai, and numerous resident and migratory birds.

Explanation

Sunil Chopra, a Delhi-born businessman and politician, was elected as the Mayor of the London Borough of Southwark for the second time in May 2022. Having previously held the office during the 2014-2015 term, his re-election marked a significant milestone for the Indian diaspora in the United Kingdom. Chopra represents the Labour Party and has been an active member of the Southwark Council for several years, focusing on community development and local business interests. His leadership in the borough, which includes major landmarks like the Shard and Tower Bridge, underscores the prominent role of Indian-origin individuals in British local government.

Explanation

The rebellion in Jhansi began on June 5, 1857, when the sepoys of the 12th Native Infantry stationed at the Star Fort revolted and seized the treasury and magazine. This outbreak occurred several weeks after the initial sparks of the revolt. The date May 11, 1857, is historically significant for the arrival of the Meerut mutineers in Delhi, where they declared Bahadur Shah Zafar as the Emperor of India. In Jhansi, Rani Lakshmibai initially sought to maintain peace with the British authorities but was eventually drawn into the conflict following the violent uprising of the local troops in early June. Therefore, the association of May 11 with Jhansi is chronologically inaccurate.

Explanation

The Coriolis force is an inertial force generated by the Earth's rotation from west to east. It acts on all moving objects, including winds and ocean currents, that travel over the Earth's surface. Because the linear velocity of rotation varies with latitude, moving air particles appear to deviate from a straight-line path when viewed from the rotating frame of reference. In the Southern Hemisphere, this effect causes moving air to deflect towards the left of its direction of motion. The magnitude of this force is defined by the formula 2vω sin φ, where v is the wind speed, ω is the Earth's angular velocity, and φ is the latitude. This deflection is fundamental to the formation of large-scale atmospheric circulation patterns and cyclonic movements.

Explanation

The Water (Prevention and Control of Pollution) Act was enacted by the Indian Parliament in 1974. This landmark legislation was the first major environmental law in India specifically designed to create a regulatory structure for the prevention and control of water pollution. The primary objectives of the Act are to maintain or restore the wholesomeness of water and to prevent the discharge of domestic and industrial effluents into water bodies without proper treatment. To enforce these provisions, the Act led to the establishment of the Central Pollution Control Board and various State Pollution Control Boards, which are empowered to set standards, conduct inspections, and take legal action against polluters.

Explanation

The Geological Survey of India (GSI) identified lithium inferred resources (G3 stage) of approximately 5.9 million tonnes in the Salal-Haimana area of Reasi district in Jammu and Kashmir, a significant finding announced in early 2023. Additionally, India lacks substantial domestic mining operations for several critical minerals essential for the green energy transition and high-tech industries. Specifically, the country relies heavily on imports for Lithium, Nickel, and Cobalt to meet the requirements of its domestic manufacturing sectors, including the production of lithium-ion batteries for electric vehicles and electronic devices.

Explanation

The stratosphere is the second major layer of Earth's atmosphere, extending from approximately 10 to 50 kilometers above the surface. It contains the ozone layer, a region where the concentration of ozone (O₃) molecules is highest. This layer performs the vital function of absorbing approximately 97 to 99 percent of the Sun's medium-frequency ultraviolet (UV) radiation, which would otherwise be harmful to life on the surface. The absorption of this UV radiation results in a photochemical reaction that releases heat, causing temperatures within the stratosphere to increase with altitude.

Explanation

Space research is not included in the list of seventeen Sustainable Development Goals (SDG) adopted by all United Nations Member States in 2015 as part of the 2030 Agenda for Sustainable Development. The SDGs are a universal call to action to end poverty, protect the planet, and ensure that by 2030 all people enjoy peace and prosperity. These seventeen goals focus on global challenges related to poverty, inequality, climate change, environmental degradation, peace, and justice. While space-based technology and satellite data are often used as tools to help monitor and achieve various targets, space research itself is not categorized as a primary goal or a specific target within the official 2030 framework.

Explanation

World Wetlands Day is observed annually on 2 February to commemorate the date of the adoption of the Convention on Wetlands in 1971. This international treaty, commonly known as the Ramsar Convention, was signed in the Iranian city of Ramsar to provide a framework for the conservation and wise use of wetlands and their resources. The day aims to raise global awareness about the vital role wetlands play in maintaining biodiversity, providing clean water, and mitigating the effects of climate change. The United Nations General Assembly officially recognized this observance in 2021 to emphasize the importance of these ecosystems for sustainable development and human wellbeing.

Explanation

The World Social Protection Report is published by the International Labour Organization (ILO), a specialised agency of the United Nations established in 1919 with its headquarters in Geneva. The report provides a comprehensive assessment of social protection systems and policies worldwide, analysing coverage of social security schemes, benefit levels, and financing mechanisms. It benchmarks countries' progress toward universal social protection, covering areas such as old-age pensions, disability benefits, child allowances, unemployment insurance, and health care. The ILO uses this report to guide member states toward achieving SDG Goal 1.3.

Explanation

Explanation

The Reserve Bank of Australia announced on February 2, 2023, that it would replace the portrait of Queen Elizabeth II on its five-dollar banknote with a new design representing the culture and history of First Australians. This decision ensured that King Charles III would not appear on the nation's paper currency, marking a shift toward recognizing indigenous heritage on its legal tender. The move followed consultations with the federal government to ensure the currency reflects Australia's evolving national identity. While the British monarch remains the head of state and continues to appear on Australian coins, the update to the five-dollar note effectively removed the monarchy from the country's banknotes.

Explanation

Zain-ul-Abidin, who ruled Kashmir from 1420 to 1470, is widely regarded as the greatest Sultan of the Shah Mir dynasty and is popularly known as Bud Shah or the Great King. His reign was characterized by a period of peace, prosperity, and religious harmony. Reversing the harsh policies of his predecessors, he adopted a policy of broad religious tolerance. He abolished the Jizya tax on his Hindu subjects and prohibited the slaughter of cows to respect their religious sentiments. Additionally, he allowed Hindus who had fled the valley during earlier periods of persecution to return, reconstructed many of their destroyed temples, and appointed them to high administrative positions. His liberal governance and cultural patronage have often led historians to describe him as the Akbar of Kashmir.

Explanation

The Pranhita River is the largest tributary of the Godavari River, contributing approximately 34 percent of its total discharge. It is formed by the confluence of three major rivers: the Wardha, the Penganga, and the Wainganga. The Pranhita flows along the border of Maharashtra and Telangana before joining the Godavari at Kaleshwaram. The Mahanadi River, which drains through Chhattisgarh and Odisha, has its own distinct set of tributaries such as the Seonath, Hasdeo, Mand, Ib, Jonk, and Tel. Since the Pranhita is an integral part of the Godavari basin, pairing it with the Mahanadi is geographically incorrect.
