Explanation

In February and March 2014, Maharashtra was hit by an unprecedented series of hailstorms that were recorded as the most severe in the state's history. The disaster affected 28 out of 35 districts, destroying crops across approximately 1.9 million hectares of land. The unseasonal weather was caused by the collision of moisture-laden winds from the Arabian Sea and the Bay of Bengal with cold northerly winds. This resulted in massive losses for farmers growing Rabi crops, especially high-value horticultural produce such as grapes, pomegranates, mangoes, and oranges, along with staples like wheat and onions. The scale of agricultural destruction in Maharashtra far exceeded that of any other state during this period, leading to a significant socio-economic crisis in the Marathwada and Vidarbha regions.

The title of the book corresponds to the duration of 1,001 nights, reflecting the novel's thematic and structural roots in the classic folk tales of One Thousand and One Nights. It explores themes of religion, reason, and the struggle between order and chaos through the lens of a long-lost lineage of half-human, half-jinn descendants.

Explanation

Prime Minister Narendra Modi delivered his maiden address to the 69th session of the United Nations General Assembly in New York on September 27, 2014. During this historic speech, which he chose to deliver in Hindi, he touched upon various global issues including sustainable development, terrorism, and international security. A significant highlight of this address was his proposal to the United Nations to observe an International Day of Yoga, which was subsequently adopted by the UN General Assembly later that year.

Explanation

Chinese President Xi Jinping began his three-day state visit to India on September 17, 2014, by arriving in Ahmedabad, Gujarat. This marked a significant departure from diplomatic protocol, as it was the first time a visiting head of state started an official tour in a city other than the national capital, New Delhi. The arrival coincided with the 64th birthday of Prime Minister Narendra Modi, who personally received the Chinese President. During his stay in Ahmedabad, President Xi visited the Sabarmati Ashram and the Sabarmati Riverfront. The two leaders also oversaw the signing of several agreements in the city, including a sister-city pact between Ahmedabad and Guangzhou and the establishment of Chinese industrial parks in Gujarat, before the delegation moved to New Delhi for formal bilateral discussions.

Explanation

During the Syrian Civil War, the nerve agent Sarin was used in a major chemical attack on August 21, 2013, in the Ghouta region near Damascus. Sarin is a clear, colorless, and odorless liquid that is categorized as a weapon of mass destruction. It functions as a potent nerve agent by inhibiting the enzyme acetylcholinesterase, which is responsible for breaking down the neurotransmitter acetylcholine in the nervous system. When this enzyme is blocked, acetylcholine builds up, leading to constant stimulation of muscles and glands, eventually causing paralysis and death by respiratory failure. Following the international outcry over the Ghouta attack, a United Nations report confirmed the use of Sarin, leading to a diplomatic agreement for the dismantling and destruction of Syria's chemical weapon stockpiles under the supervision of the Organisation for the Prohibition of Chemical Weapons.

Explanation

The 2014 FIFA World Cup was the 20th edition of the quadrennial international football championship and was hosted by Brazil. The tournament took place from 12 June to 13 July 2014, with matches played in 12 venues across 12 different cities throughout the country. Brazil was chosen as the host nation in 2007 by the FIFA Executive Committee under the continental rotation system used at the time. The event featured 64 matches in total, culminating in the final match held at the Maracana Stadium in Rio de Janeiro. This tournament marked the second time Brazil hosted the competition, the first being in 1950.

Explanation

The United States government updated its policy regarding the export of military-grade Unmanned Aerial Systems in early 2015, allowing for the sale of sophisticated drones to a wider range of allied nations under strict conditions. This policy shift led to specific approvals and sales agreements for countries seeking to enhance their maritime surveillance and regional security capabilities, such as Japan, Malaysia, and the United Arab Emirates. Singapore was not among the countries included in this specific set of high-profile approvals or new export agreements reported during that particular period. At the time, Singapore primarily relied on its own indigenous drone programs and existing technology partnerships with other nations like Israel for its aerial surveillance needs, rather than being part of this specific 2015 batch of U.S. drone export clearances.

Explanation

Agni-5 is a long-range nuclear-capable ballistic missile developed by the Defence Research and Development Organisation (DRDO). While the missile is highly advanced and utilizes a canister-based launch system for mobility and speed, it is not invisible to radar. No ballistic missile of this category is completely immune to detection; they can be tracked by sophisticated ground-based early warning radars, sea-based X-band radars, and space-based infrared sensors that detect the massive heat signature generated during the launch and mid-course phases of flight. Modern missile defense architectures are specifically designed to identify and track the trajectory of such high-altitude projectiles once they exit the denser layers of the atmosphere.

Explanation

During a major policy speech at the University of Queensland in Brisbane in November 2014, President Barack Obama articulated the United States' position on maritime security in the Asia-Pacific region. He specifically addressed the escalating territorial disputes in the South China Sea, stating that big nations should not bully small ones. Obama emphasized that the resolution of these conflicts, particularly those involving China and its neighbors like the Philippines and Vietnam, must be based on international law and peaceful diplomacy rather than coercion or intimidation. This statement was a significant part of the U.S. pivot to Asia strategy, aimed at upholding the freedom of navigation and ensuring that regional stability was not compromised by unilateral actions or the threat of force by larger powers over smaller sovereign states.

Explanation

The Andhra Pradesh Reorganisation Act, 2014, which provided for the bifurcation of the state of Andhra Pradesh into two new states, Telangana and the residuary state of Andhra Pradesh, received the assent of the President of India on March 1, 2014. The bill had been passed by the Lok Sabha on February 18, 2014, and by the Rajya Sabha on February 20, 2014. Once President Pranab Mukherjee signed the bill on March 1, it was published in the Official Gazette, completing the legislative process for the creation of India's 29th state. The Act eventually came into effect on the Appointed Day, which was June 2, 2014.

Explanation

The Unorganised Workers' Social Security Act was enacted by the Parliament of India in 2008 to provide for the social security and welfare of workers in the unorganised sector. This legislation received the assent of the President on December 30, 2008. It provides a legal framework for the Central Government to formulate welfare schemes covering life and disability insurance, health and maternity benefits, and old age protection. The Act also mandated the establishment of the National Social Security Board and State Social Security Boards to recommend and monitor the implementation of these schemes for various categories of informal workers, including home-based workers, self-employed persons, and daily wage earners.

Explanation

Standard of living is a socioeconomic indicator that represents the level of wealth, comfort, material goods, and necessities available to a certain individual or group. It is primarily determined by economic factors such as income levels, gross domestic product (GDP), cost of goods and services, and poverty rates. Unlike demographic features, which are statistical and quantitative data used to describe the composition, distribution, and biological characteristics of a population, standard of living measures the quality of life and economic well-being. Therefore, it is categorized as an economic or social attribute rather than a demographic one.

Explanation

Investment in human capital involves expenditures on education, vocational training, and healthcare to enhance the qualitative capacity of the workforce. By improving the knowledge and physical well-being of individuals, such investment directly facilitates the development of specialized skills and technical expertise. A highly skilled population operates more efficiently, which significantly boosts the overall productivity of the economy. Additionally, educated and trained human resources are essential for the proper utilization of physical capital and natural resources, as they possess the capability to innovate and manage complex production processes effectively. These factors collectively contribute to sustainable economic growth through the qualitative transformation of the labor force.

Explanation

Bamiyan was officially inaugurated as the first-ever SAARC Cultural Capital for the year 2015 during a ceremony held in the central Afghan province. This designation was part of a SAARC initiative aimed at promoting cultural ties and regional integration among member nations. Historically renowned for its rich heritage, particularly its ancient Buddhist archaeological sites and the remnants of the giant Buddha statues, Bamiyan was selected to showcase South Asian cultural diversity and foster tourism within the region. The program included various cultural festivals, exhibitions, and artistic performances scheduled throughout the year to celebrate the unique heritage of this historic Silk Road hub.

Explanation

The Government of Gujarat launched the M.L.A. Adarsh Gram Yojana following the introduction of the Sansad Adarsh Gram Yojana by the Central Government in October 2014. Under this state-level initiative, each Member of the Legislative Assembly was encouraged to adopt a village in their constituency to develop it into a model village. The scheme focused on the holistic development of rural areas by converging various existing government schemes to improve infrastructure, health, education, and sanitation while promoting social harmony and community participation. This was intended to create a ripple effect of development across rural clusters in the state.

Explanation

The Uttar Pradesh state cabinet in 2015 approved a proposal to establish a forensic science university in Rampur. This institution was envisioned as the second specialized forensic university in India, modeled after the Gujarat Forensic Sciences University in Gandhinagar which was established in 2008. The project aimed to address the shortage of forensic experts and improve the quality of criminal investigations and judicial proceedings in the state. By providing advanced research and training facilities in disciplines like toxicology, DNA profiling, and cyber forensics, the university was intended to serve as a premier center for forensic education in Northern India.

Explanation

Bharat Nirman is a time-bound business plan launched by the Government of India in 2005 to develop rural infrastructure. It focuses on six key components: rural housing, irrigation, drinking water, rural roads, rural electrification, and rural telephony. It is categorized as an infrastructure development program rather than a social security measure. Social security refers to government initiatives designed to provide a financial safety net for vulnerable populations, such as old-age pensions, life insurance, or disability benefits. Because Bharat Nirman is dedicated to building physical assets in rural areas, it does not fall under the category of social security.

Explanation

Occupational structure refers to the distribution of the working population across various sectors of the economy, typically categorized into primary, secondary, and tertiary sectors. The primary sector includes activities like agriculture, forestry, and fishing; the secondary sector encompasses manufacturing and construction; and the tertiary sector involves services such as trade, transport, and banking. This distribution serves as a vital indicator of a country level of economic development, as a shift of the workforce from primary to secondary and tertiary sectors generally signifies industrialization and modernization within an economy.

Explanation

NABARD is the nodal agency that conceived and promoted the Self Help Group (SHG)-Bank Linkage Programme in 1992. It functions as the facilitator, provider of policy guidelines, and refinancing body for the scheme. The actual field-level implementation and the direct extension of credit to SHGs are performed by the retail banking sector. Commercial Banks, Regional Rural Banks (RRBs), and Co-operative Banks are the primary implementing entities that interact directly with the groups, handle their savings accounts, and provide linkage loans. NABARD maintains an apex role by monitoring the progress and providing financial assistance to these banks to sustain the credit flow, but it does not carry out the implementation of the programme at the ground level.

Explanation

The Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) was enacted by the Parliament of India in August 2005 and was officially launched on February 2, 2006. Originally called the National Rural Employment Guarantee Act (NREGA), it was renamed in 2009 to honor Mahatma Gandhi. The scheme provides a legal guarantee for at least 100 days of wage employment in every financial year to every rural household whose adult members volunteer to do unskilled manual work. Since the legislation was passed and implemented between 2005 and 2006, the year 2003 is an incorrect match for this program.

Explanation

An increase in the size of the working population is a positive outcome of population growth often referred to as the demographic dividend. This phenomenon provides a larger pool of labor resources, which serves as a primary factor of production capable of driving economic expansion and increasing the Gross Domestic Product. A growing labor force represents an accumulation of human capital that can enhance productivity and innovation if effectively integrated into the economy. This growth in the productive segment of the population allows for a lower dependency ratio and higher potential for savings and investment, contributing to the overall economic development of a nation.

Explanation

Land reforms in India refer to institutional and structural changes aimed at redistributing land ownership and improving the relationship between the tiller and the land to ensure social justice. These reforms traditionally encompass the abolition of intermediaries, tenancy regulations regarding rent and security of tenure, and the imposition of land ceiling limits to redistribute surplus land to the landless. The Multiple Cropping Scheme is an agronomic or technological intervention focused on increasing agricultural productivity and crop intensity by growing more than one crop on the same plot of land within a single year. It is a part of agricultural development strategies and the Green Revolution rather than a legal or structural modification of land tenure and ownership patterns.

Explanation

India is currently in the late third stage of the demographic transition, characterized by a high absolute growth but with a clear declining trend in the growth rate. While the population continues to expand due to a large base and population momentum, the decadal growth rate has seen a significant drop from 21.54 percent in the 1991-2001 period to 17.64 percent in the 2001-2011 period. This slowdown is evidenced by the consistent decrease in the Total Fertility Rate (TFR), which is moving toward the replacement level of 2.1. Improvements in literacy, healthcare, and family planning have led to a sharper decline in birth rates compared to death rates, confirming the phase of high growth with definite signs of slowing down.

Explanation

The Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) mandates that at least one-third of the total person-days generated must be for women. In practice, the participation of women has significantly exceeded this legal minimum. According to the data released by the Ministry of Rural Development for the financial year 2013-14, the share of women in total employment generated under the scheme was recorded at 52.9%. This high level of participation is attributed to the scheme's provisions such as equal wages for men and women, work availability within a 5-kilometer radius of the residence, and the provision of crèche facilities at worksites, which facilitate the inclusion of female laborers in the rural workforce.

Explanation

The primary sector of an economy involves the direct extraction or production of natural resources. Agriculture is the most significant activity within this sector in India, encompassing crop cultivation, animal husbandry, forestry, and fishing. These activities rely heavily on natural factors such as soil, water, and climate. Historically, agriculture has been the foundational base of the Indian economy, serving as the largest source of employment and providing the necessary raw materials for various processing industries. In the Indian economic framework, the primary sector is defined by these nature-based activities that yield basic food items and industrial inputs directly from the earth and biological processes.

Explanation

The Indian economy is a mixed economy because it features the simultaneous existence of both the public and private sectors. In this system, the state and the private market interact to solve basic economic problems. While the private sector operates for profit and responds to market forces, the public sector focuses on social welfare and the development of strategic infrastructure. This model was officially adopted after independence through the Industrial Policy Resolutions of 1948 and 1956 to ensure balanced regional development and to prevent the concentration of economic power. Even after the 1991 reforms which increased the role of the market, the Indian government continues to maintain control over vital sectors and implements various social security schemes, thereby upholding the characteristics of a mixed economic structure.

Explanation

The National Food Security Mission (NFSM) was launched in 2007-08 by the Government of India with the primary objective of increasing the production of specific food grains through area expansion and productivity enhancement. During the 11th Five Year Plan, the mission focused exclusively on rice, wheat, and pulses. Although the scope of the mission was expanded during the 12th Five Year Plan to include coarse cereals and certain commercial crops, oilseeds were never part of the NFSM. Instead, the production and development of oilseeds were managed under different administrative frameworks, such as the Integrated Scheme of Oilseeds, Pulses, Oil Palm and Maize (ISOPOM) and later the National Mission on Oilseeds and Oil Palm (NMOOP), which was implemented as a separate mission starting in 2014-15.

Explanation

Sarva Shiksha Abhiyan (SSA) is the Government of India's flagship program aimed at the universalization of elementary education in a time-bound manner. It was launched to fulfill the mandate of the 86th Amendment to the Constitution of India, which introduced Article 21A, making free and compulsory education a Fundamental Right for children. Specifically, the program targets all children in the age group of 6-14 years to ensure they receive eight years of quality elementary schooling. This age range is legally reinforced by the Right of Children to Free and Compulsory Education (RTE) Act, 2009, which provides the implementation framework to ensure that every child in this specific bracket has access to education. SSA focuses on infrastructure development, teacher recruitment, and the removal of gender and social category gaps in elementary education.

Explanation

The Green Revolution, known as the New Agricultural Strategy, was officially introduced in India during the mid-sixties, specifically starting with the Kharif season of 1966. This strategy was adopted to address chronic food shortages and the country's dependence on food imports under the PL-480 program. It focused on the adoption of modern methods and technology, including the use of High Yielding Variety (HYV) seeds, particularly for wheat and rice, alongside improved irrigation facilities and the increased application of chemical fertilizers and pesticides. The initial phase of this strategy was concentrated in regions with assured water supply, such as Punjab, Haryana, and Western Uttar Pradesh, leading to a significant increase in food grain production.

Explanation

Bharat Nirman was launched by the Government of India in 2005 as a time-bound business plan for creating and improving basic rural infrastructure. It focuses on six critical components: rural housing, irrigation potential, drinking water, rural roads, electrification, and rural telephony. The National Rural Drinking Water Programme serves as the specific implementing framework for the drinking water component of this initiative. Launched in 2009 by restructuring the earlier Accelerated Rural Water Supply Programme, it aims to ensure that every rural household has access to safe and adequate drinking water for health and hygiene. By being integrated into Bharat Nirman, the programme receives prioritized funding and monitoring to meet national infrastructure development targets in rural areas.

Explanation

The Mahatma Gandhi National Rural Employment Guarantee Act (MNREGA) serves as a social security measure that guarantees the right to work by providing at least 100 days of wage employment in a financial year to every rural household. By ensuring a statutory minimum wage and providing a safety net of guaranteed income, the scheme has led to a substantial increase in the purchasing power of the rural poor, thereby boosting rural consumption. Additionally, by creating employment opportunities locally within the village or nearby areas, especially during the lean agricultural seasons, it has effectively curtailed distress migration to urban centers. Rather than reducing bargaining power, the scheme actually strengthens the position of rural laborers against private employers by establishing a reservation wage below which workers are unwilling to accept employment.

Explanation

Bharat Nirman was a time-bound business plan for rural infrastructure development launched by the Government of India in 2005. The program specifically identified six components to be addressed: irrigation, rural roads, rural housing, rural water supply, rural electrification, and rural telephony. While sanitation is a critical aspect of rural development, it was handled through distinct schemes like the Total Sanitation Campaign and the later Nirmal Bharat Abhiyan. Consequently, rural sanitation was not listed as one of the six core pillars of the Bharat Nirman initiative during its inception or implementation.

Explanation

According to the Census 2011 data, Bihar recorded the lowest literacy rate in the country at 61.80%. Within this total, the male literacy rate stood at 71.20% while the female literacy rate was 51.50%. These figures placed the state at the bottom of the national rankings during the 2011 decadal census, falling well below the aggregate national literacy average of 74.04%.

Explanation

The Right of Children to Free and Compulsory Education Act, 2009, was enacted to implement the fundamental right guaranteed under Article 21A of the Constitution of India. This constitutional provision mandates the State to provide free and compulsory education to all children in the age group of six to fourteen years. Under Section 2(f) of the RTE Act, elementary education is specifically defined as the education from the first class to the eighth class. The primary objective of the legislation is to ensure that every child has access to a neighborhood school and completes their schooling through the eighth grade without being subjected to any tuition fees or expenses that might hinder their access to education.

Explanation

Urbanization in India acts as a primary engine of economic development by facilitating agglomeration economies. The concentration of labor, capital, and infrastructure in urban centers directly fosters industrial growth through improved supply chains and market access. Simultaneously, these hubs are essential for the expansion of the modern service sector, including information technology, finance, and telecommunications, which require dense networks of skilled professionals. This economic concentration enhances productivity and leads to the creation of improved income opportunities, as urban labor markets offer diverse employment paths and higher wage potential compared to rural agricultural sectors. Consequently, the expansion of urban India serves as a multifaceted platform that integrates industrial advancement, service sector evolution, and socio-economic mobility.

Explanation

Haemoglobin is a complex iron-containing protein found within red blood cells that is essential for the transport of respiratory gases. Each haemoglobin molecule contains four heme groups, each featuring an iron ion (Fe²⁺) that can bind reversibly with one molecule of oxygen. In the pulmonary capillaries of the lungs, where oxygen concentration is high, oxygen binds to haemoglobin to form oxyhaemoglobin. This oxygenated blood is then circulated by the heart to the rest of the body. Upon reaching systemic tissues where oxygen levels are low, the oxyhaemoglobin dissociates, releasing the oxygen molecules to the cells for aerobic respiration. This highly efficient binding and release mechanism allows blood to carry approximately seventy times more oxygen than could be transported by physical dissolution in plasma alone.

Explanation

Subrahmanyan Chandrasekhar formulated the Chandrasekhar Limit in 1930, which provided the first rigorous mathematical basis for the existence of black holes. He calculated that a white dwarf star with a mass greater than approximately 1.44 times that of the Sun (the Chandrasekhar Limit) would be unable to support itself against gravitational collapse using electron degeneracy pressure. This theoretical discovery implied that sufficiently massive stars would continue to collapse indefinitely into a singularity, establishing the physical necessity of what are now known as black holes. He was awarded the Nobel Prize in Physics in 1983 for these contributions to the study of stellar structure and evolution.

Explanation

CNG stands for Compressed Natural Gas. It is a fuel gas mainly composed of methane (CH₄) that has been compressed to less than 1 percent of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20 to 25 megapascals. CNG is utilized as an eco-friendly alternative to gasoline and diesel because its combustion produces significantly fewer harmful emissions, such as carbon monoxide, nitrogen oxides, and particulate matter. Since it is lighter than air, it disperses quickly in the event of a leak, making it safer than many liquid fuels.

Explanation

Convex mirrors are employed as rear-view mirrors in vehicles primarily because they provide a significantly wider field of view than other mirror types. Due to their outward curvature, these mirrors diverge light rays, allowing the driver to see a much broader area of the road and traffic behind them. Additionally, convex mirrors always form an erect and virtual image that is smaller than the actual object. This diminished image size enables the mirror to fit a larger portion of the surrounding environment into its reflection, which is crucial for monitoring multiple lanes and minimizing blind spots during driving.

Explanation

Ozone depletion refers to the thinning of the stratospheric ozone layer, which acts as a shield against harmful solar radiation. When this layer is depleted, higher levels of ultraviolet-B (UV-B) radiation reach the Earth's surface. Exposure to UV-B is directly linked to an increased risk of skin cancer in humans, including basal cell carcinoma, squamous cell carcinoma, and malignant melanoma. The UV radiation causes genetic damage to skin cells, specifically by inducing the formation of pyrimidine dimers in DNA, which leads to mutations during cell replication. This biological impact makes the protection of the ozone layer a critical public health concern.

Explanation

C.F.L. stands for Compact Fluorescent Lamp. These lamps were designed as energy-efficient alternatives to traditional incandescent light bulbs. They function by passing an electric current through a tube containing argon and a small amount of mercury vapor. This process generates invisible ultraviolet (UV) light that excites a fluorescent coating, known as phosphor, on the inside of the tube, which then emits visible light. The term compact refers to the specific design where the fluorescent tube is folded or curved to minimize space, allowing it to fit into standard light fixtures originally intended for incandescent bulbs. Compared to incandescent lamps of the same luminous flux, C.F.L.s use significantly less power and have a longer rated life.

Explanation

Car batteries are primarily lead-acid batteries, which consist of lead and lead dioxide electrodes immersed in an electrolyte solution. This electrolyte is dilute sulphuric acid (H₂SO₄), typically maintained at a concentration of approximately 33% to 38% by weight in a fully charged state. During the discharging process, the lead (Pb) on the negative plate and the lead dioxide (PbO₂) on the positive plate react with the sulphuric acid to produce lead sulphate (PbSO₄) and water (H₂O). This chemical reaction facilitates the flow of electrons, providing the electrical energy needed to start the vehicle and power its electrical systems. Sulphuric acid is used because it provides the essential ions required for these reversible electrochemical reactions.

Explanation

India's maiden interplanetary mission, the Mars Orbiter Mission (MOM), also known as Mangalyaan, was launched by the Indian Space Research Organisation (ISRO) on November 5, 2013. The mission utilized the PSLV-C25 rocket, a variant of the Polar Satellite Launch Vehicle, which lifted off from the First Launch Pad at the Satish Dhawan Space Centre, Sriharikota. The mission was designed to showcase India's rocket launch systems, spacecraft capabilities, and operations while performing secondary scientific tasks such as exploring Martian surface features, morphology, mineralogy, and the Martian atmosphere using indigenous scientific instruments. Following its successful launch, the spacecraft completed a series of orbit-raising maneuvers before being placed into a trans-Mars trajectory and ultimately entering Martian orbit on September 24, 2014.

Explanation

The World Wide Web, commonly known as the Web or WWW, was invented by Tim Berners-Lee in 1989 while he was working at CERN. It is an information system where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and accessible via the Internet. The Web operates through the Hypertext Transfer Protocol (HTTP) and utilizes Hypertext Markup Language (HTML) to format and display content on web browsers.

Explanation

Vitamin C, or ascorbic acid, is necessary for the production of collagen and the maintenance of skin and gums; its deficiency leads to scurvy. Folic acid is a B-vitamin required for the synthesis of DNA and the formation of red blood cells, and its deficiency causes megaloblastic anaemia. Vitamin A is essential for the health of the retina and the ability to see in low light, and its deficiency results in night blindness. These biochemical relationships correspond to the sequence 4, 3, and 1 for the items listed.

Explanation

The 102nd Indian Science Congress was hosted by the University of Mumbai from January 3 to 7, 2015. The event was inaugurated by Prime Minister Narendra Modi and centered on the theme Science and Technology for Human Development. This session marked the return of the prestigious gathering to Mumbai after a period of 45 years. It featured various sessions including the Children Science Congress and the Women Science Congress, providing a platform for scientists, researchers, and Nobel laureates to discuss the role of scientific advancements in societal progress.

Explanation

When an onion is cut or peeled, its cell walls are ruptured, allowing enzymes known as alliinases to come into contact with sulfur-containing compounds called amino acid sulfoxides. This reaction leads to the production of 1-propenylsulfenic acid. This sulfenic acid is then rapidly converted by another enzyme, the lachrymatory factor synthase, into syn-propanethial-S-oxide. This volatile gas travels through the air and, upon reaching the moisture in the eyes, forms a mild sulfuric acid that irritates the sensory nerves, causing the lachrymal glands to release tears to wash away the irritant.

Explanation

Teflon is the brand name for the synthetic fluoropolymer known as Polytetrafluoroethylene (PTFE). It is synthesized through the polymerization of tetrafluoroethylene (F₂C=CF₂) monomers. The material is highly valued for its exceptional thermal stability and chemical inertness, which stems from the extremely strong bonds between carbon and fluorine atoms. Because it possesses one of the lowest coefficients of friction of any known solid, it creates a surface that is both water-repellent and oil-repellent. These unique non-reactive and slippery properties prevent food from adhering to the surface during heating, making it the primary coating used in the manufacture of non-stick cookware.

Explanation

The White Revolution, also known as Operation Flood, was launched in 1970 by the National Dairy Development Board (NDDB) to transform India into a self-sufficient, milk-producing nation. It was the world's largest dairy development program and was spearheaded by Dr. Verghese Kurien, who is widely recognized as the Father of the White Revolution in India. The movement followed the cooperative model of Amul, which focused on creating a national milk grid to link rural milk producers directly with urban consumers. This system eliminated middlemen, ensured that dairy farmers received a major share of the profits, and led to a massive increase in the per capita availability of milk across the country.

Explanation

In a pressure cooker, the steam generated during heating is trapped within the sealed vessel, causing the internal pressure to rise significantly above standard atmospheric pressure. According to the relationship between pressure and phase changes, the boiling point of a liquid increases as the pressure acting upon its surface increases. While water normally boils at 100°C at sea level, the high pressure inside the cooker raises this boiling point to approximately 120°C or higher. This allows the water and steam to reach a much higher temperature without evaporating away. Since the rate of heat transfer and the speed of chemical reactions involved in cooking are temperature-dependent, the hotter environment enables the food to cook much faster than it would in an open pot at a lower temperature.

Explanation

The number of images n formed by two plane mirrors inclined at an angle θ is determined by the formula n = 360°/θ - 1. When two mirrors are placed parallel to each other, the angle θ between them is 0°. Mathematically, as the angle θ approaches zero, the value of 360°/θ approaches infinity.

Physically, this occurs because light from the source is reflected back and forth between the two mirrors multiple times. Each image produced by the first mirror serves as a virtual object for the second mirror, which then creates a new image. This second image, in turn, acts as a virtual object for the first mirror again. Since the mirrors are parallel, this process of successive reflections continues indefinitely, resulting in an infinite series of images arranged in a straight line passing through the light source and perpendicular to the mirror surfaces.

Explanation

The Green Revolution in India, launched in the mid-1960s under the leadership of M.S. Swaminathan, focused on the adoption of modern agricultural practices and technology. The core of this movement was the introduction of High Yielding Variety (HYV) seeds, which were most successful and impactful in wheat cultivation. The transition from traditional farming to industrial agriculture led to a massive increase in food grain production, with wheat yields seeing such a dramatic rise that the initial phase of the movement is frequently termed the Wheat Revolution. This transformation was supported by the intensive use of chemical fertilizers, pesticides, and improved irrigation systems to maximize the genetic potential of the semi-dwarf wheat varieties developed by Norman Borlaug.

Explanation

Silicon is the primary semiconductor material used in the fabrication of transistors due to its excellent electrical properties and high abundance. As a tetravalent element, its crystal lattice can be easily doped with impurities to create p-type and n-type regions, which are the fundamental building blocks of p-n junctions. A major technical advantage of silicon is its ability to form a stable, high-quality native oxide layer, silicon dioxide (SiO₂), through thermal oxidation. This insulating layer is crucial for the manufacturing of Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs), as it acts as an effective gate dielectric. Additionally, silicon has a bandgap of approximately 1.12 eV, which provides a good balance between conductivity and low leakage current, allowing electronic devices to operate reliably at the temperatures typically found in consumer and industrial electronics. Its cost-effectiveness and the well-established infrastructure for silicon wafer processing have made it the industry standard for integrated circuits.

Explanation

Carbon dioxide (CO₂) is the primary greenhouse gas responsible for the enhancement of the greenhouse effect. It acts by allowing incoming short-wave solar radiation to pass through the atmosphere to the Earth's surface but absorbing the outgoing long-wave infrared radiation (heat) re-emitted by the planet. This trapped thermal energy is then radiated back toward the surface, leading to an increase in atmospheric temperature. The concentration of CO₂ has risen significantly due to human activities such as the combustion of fossil fuels, deforestation, and industrial processes, making it the largest contributor to anthropogenic global warming among all greenhouse gases.

Explanation

Iodine is a trace element that is primarily utilized by the thyroid gland to synthesize thyroid hormones, namely thyroxine (T₄) and triiodothyronine (T₃). These hormones are essential for regulating metabolic rate, protein synthesis, and proper physical and neurological development. While iodine is vital for overall endocrine health and growth, it does not play a direct structural role in the mineralization of the skeletal system or the hardening of dental enamel. Deficiency in iodine typically results in thyroid-related disorders such as goiter or hypothyroidism rather than the impairment of bone or tooth integrity.

Explanation

Albert Einstein was awarded the Nobel Prize in Physics in 1921 for his discovery of the law of the photoelectric effect. In his landmark 1905 paper, Einstein proposed that light is composed of discrete packets of energy called photons, rather than behaving solely as a continuous wave. He established that the energy E of a photon is directly proportional to its frequency ν through the relation E = hν, where h is Planck's constant. When light hits a material, these photons transfer energy to electrons; an electron is emitted only if the photon energy is greater than the material's work function Φ. The maximum kinetic energy of the ejected electron is calculated using the equation Kₘₐₓ = hν - Φ. This explanation provided the first definitive evidence for the particle nature of light and was a cornerstone in the development of quantum mechanics.

Explanation

Womesh Chandra Banerjee, a prominent Bengali barrister, presided over the inaugural session of the Indian National Congress held at Gokuldas Tejpal Sanskrit College in Bombay from December 28 to December 31, 1885. This first assembly was attended by 72 delegates from across India and laid the foundation for the organized nationalist movement against British colonial rule. Banerjee was a respected legal professional and a moderate leader whose presidency marked the formal beginning of the Indian National Congress as a political platform for articulating Indian interests.

Explanation

Dharmapala, the second ruler of the Pala Dynasty of Bengal and Bihar, established Vikramshila University during the late 8th or early 9th century. Located at Antichak in the Bhagalpur district of Bihar, it became one of the most important centers of Buddhist learning in India, second only to Nalanda. Dharmapala was a devout patron of Buddhism and founded the university to promote the Vajrayana sect and various branches of Sanskrit learning. Under his patronage, the institution attracted scholars from across Asia, particularly from Tibet, and played a significant role in the dissemination of Buddhist philosophy and culture.

Explanation

Abanindranath Tagore, along with his brother Gaganendranath Tagore, established the Indian Society of Oriental Art in Kolkata in 1907. The society was founded to promote and revive traditional Indian art forms and indigenous aesthetics, acting as a cornerstone for the Bengal School of Art. It sought to counter the dominance of Western academic realism imposed by British art education by emphasizing Indian themes, styles, and techniques such as the wash technique. The society played a significant role in the Indian cultural renaissance, organizing exhibitions and providing a platform for artists to explore nationalistic identity through visual arts. It received support from both Indian patrons and European art connoisseurs, including Sir John Woodroffe, who served as its first president.

Explanation

Polycarbonates are a group of thermoplastic polymers containing carbonate groups in their chemical structures. They are specifically utilized for making bullet-proof windows and security glazing due to their exceptional impact resistance, which is significantly higher than that of ordinary glass or other transparent plastics. In bullet-resistant applications, polycarbonate is typically used as a laminated layer between sheets of glass. This composite structure allows the material to absorb the massive kinetic energy of a projectile; while the outer glass layers may crack, the polycarbonate layer stretches and deforms to prevent the bullet from penetrating and inhibits the shattering of the pane. Its high transparency, durability, and relatively low weight make it the industry standard for transparent armor.

Explanation

The Gobar Gas system was pioneered by C.B. Desai (associated with the work of S.V. Desai) at the Indian Agricultural Research Institute (IARI) in 1939. This invention utilized the process of anaerobic fermentation to convert cattle dung into a flammable gas, primarily methane, which could be used as an efficient fuel for cooking and lighting. The technology was designed to provide a sustainable energy solution for rural India while ensuring that the nutrient-rich residue or slurry could still be used as high-quality organic manure for farming. This dual-purpose system helped in managing animal waste effectively and reducing the dependence on traditional firewood.

Explanation

Cholecalciferol is the chemical name for Vitamin D₃, which is one of the two primary forms of Vitamin D. It is a fat-soluble vitamin that is naturally synthesized in the skin of humans and other animals through the action of ultraviolet B (UVB) radiation from sunlight on its precursor, 7-dehydrocholesterol. Once synthesized or ingested via food and supplements, cholecalciferol is converted in the liver and then the kidneys into its active metabolic form, calcitriol. This active form is essential for maintaining systemic calcium and phosphate levels by increasing their absorption from the intestines, thereby ensuring proper bone mineralization and preventing conditions like rickets or osteomalacia.

Explanation

Swami Vivekananda represented India and Hinduism at the inaugural Parliament of the World Religions held in Chicago in 1893. This event was part of the Worlds Columbian Exposition, organized to celebrate the 400th anniversary of Christopher Columbus arrival in the New World. Vivekananda delivered his famous keynote address on September 11, 1893, which began with the words Sisters and Brothers of America. His participation was a turning point in the history of interfaith dialogue and is credited with introducing the Indian philosophies of Vedanta and Yoga to the Western world while establishing his reputation as a global spiritual leader.

Explanation

The Abhinav Bharat Society (Young India Society) was a secret revolutionary organization founded by Vinayak Damodar Savarkar and his brother Ganesh Damodar Savarkar. It originated from the Mitramela, which was established in Nasik, Maharashtra, in 1899 and later renamed in 1904. Inspired by Giuseppe Mazzini's Young Italy movement, the society aimed to achieve Indian independence through armed rebellion and political assassinations. The association functioned primarily within the Bombay Presidency, with its headquarters and core activities centered in Nasik, Maharashtra.

Explanation

Vim Kadphises, the second ruler of the Kushan dynasty, is historically credited with the introduction of gold coinage in India for regular use. Unlike his predecessor Kujula Kadphises, who issued primarily copper currency, Vim Kadphises struck gold coins known as dinars to facilitate the flourishing maritime and overland trade with the Roman Empire. These coins maintained a high degree of purity and were modeled after the weight standards of the Roman Aureus. His coinage frequently depicted him as a devotee of Lord Shiva, often holding a trident or accompanied by the bull Nandi, marking the first large-scale adoption of gold as a medium of exchange in the Indian subcontinent. This established a monetary standard that was later expanded by Kanishka and continued through the Gupta period.

Explanation

The Gujarra Minor Rock Edict, located in the Datia district of Madhya Pradesh, is one of the few historical records where the Mauryan Emperor Ashoka is mentioned by his personal name. While most of his inscriptions across the Indian subcontinent refer to him by his titles, Devanampiya (Beloved of the Gods) and Piyadasi (He who looks with affection), the Gujarra inscription specifically uses the phrasing Devanampiyasa Piyadasino Asokarajasa. This discovery, along with similar findings at Maski, Nittur, and Udegolam, was crucial for historians to definitively link the titles found in the edicts to the king Ashoka known from Buddhist literary traditions.

Explanation

The Charter Act of 1833, also known as the Saint Helena Act 1833, finalized the transition of the British East India Company from a commercial entity into a purely administrative body. While the previous Charter Act of 1813 had ended the Company's general monopoly over Indian trade, it had specifically allowed the Company to retain its exclusive rights over the tea trade and trade with China. The Charter Act of 1833 removed these last remaining commercial privileges, requiring the Company to wind up its business affairs and cease all merchant activities. By stripping the Company of its monopoly on tea and its trade with China, the British Parliament opened these sectors to private British merchants, effectively making the Company a political agent governing India on behalf of the British Crown.

Explanation

Srimanta Sankardev was a 15th-16th century saint-scholar and social-religious reformer who initiated the Neo-Vaishnavite movement in Assam. He propagated the Ekasarana Dharma, which focuses on the worship of a single deity, Lord Krishna, as the supreme manifestation of Vishnu. His philosophy was primarily based on the teachings of the Bhagavad Gita and the Bhagavata Purana, advocating for the path of Bhakti or intense devotion over complex rituals. He is credited with creating a unique cultural and religious identity in the region through the establishment of Sattras (monasteries) and Namghars (prayer houses), where followers gather for congregational prayers and devotional singing.

Explanation

George Nathaniel Curzon, who served as the Viceroy of India from 1899 to 1905, authored the book Problems of the Far East, published in 1894. The work was written after his extensive travels through Japan, Korea, and China during the late 1880s and early 1890s. In the text, Curzon provides a detailed political and sociological analysis of these East Asian nations, evaluating their internal stability and their strategic significance to the British Empire. He particularly focused on the modernization of Japan and the potential decline of the Qing dynasty in China, framing these developments within the broader context of imperial competition and British foreign policy interests in the Pacific.

Explanation

Genghis Khan, the founder of the Mongol Empire, was born around 1162 near the Onon River in modern-day Mongolia. His birth name was Temujin (alternatively spelled Temuchin or Temurjin), a name chosen by his father following the capture of a Tatar chieftain of the same name. The name is derived from the Mongolic word temur, which means iron, suggesting strength and resilience. Temujin spent his early years unifying the various nomadic tribes of Northeast Asia through strategic alliances and military conquest. In 1206, after consolidating his power over the Mongol tribes, he was proclaimed the Great Khan at a tribal council known as the Kurultai and adopted the title Genghis Khan, which translates to Universal Ruler.

Explanation

The Tripartite Struggle was a prolonged power contest that took place during the 8th and 9th centuries for the control of Kannauj, which was considered the symbol of imperial sovereignty in North India after the reign of Harsha. The participants in this three-way conflict were the Gurjara-Pratiharas of Western India, the Palas of Bengal, and the Rashtrakutas of the Deccan. While the Cholas were a major contemporary power in South India, their political focus and military campaigns were primarily directed toward the Tamil region, Sri Lanka, and Southeast Asia. Although the Chola King Rajendra I later led a military expedition to the Ganges, the dynasty was never one of the three core rivals involved in the specific centuries-long struggle for hegemony over the Gangetic plains and the city of Kannauj.

Explanation

Mahatma Gandhi attended the Second Round Table Conference in London as the sole representative of the Indian National Congress. This participation was a direct result of the Gandhi-Irwin Pact, signed in March 1931, which stipulated that the Congress would cease the Civil Disobedience Movement in exchange for political concessions and participation in the constitutional discussions. Gandhi traveled to London on the ship SS Rajputana and stayed at Kingsley Hall. During the conference, held between September and December 1931, he voiced the Congress demand for immediate dominion status and challenged the British attempt to use communal divisions to weaken the Indian nationalist movement.

Explanation

The Indian National Congress officially declared its policy towards the Princely States for the first time during the Nagpur Session of 1920, which was presided over by C. Vijayaraghavachariar. During this session, the Congress passed a resolution calling upon the rulers of the Indian states to grant full responsible government to their subjects and to recognize their civil liberties. This marked a significant shift in the Congress's approach, as it began to formally acknowledge the political rights and aspirations of the people living in the Princely States, moving away from its earlier stance of strict non-interference. The Nagpur Session is also historically notable for reorganizing the Congress into a mass-based political organization and for ratifying the Non-Cooperation Movement.

Explanation

Dadabhai Naoroji made this statement to emphasize the fundamental principle that the primary duty of any ruler or government is to serve the interests and welfare of the people. Known as the Grand Old Man of India, Naoroji was a staunch advocate for the rights of Indians and a pioneer in explaining the economic exploitation of India under British rule. By asserting that the public is not made for the king, he challenged the absolute authority of the colonial administration and argued for a system where the government is accountable to the governed. This philosophy was central to his demand for Indian representation in the administration and eventually for self-government, as he believed that a just government must prioritize the needs of its citizens above all else.

Explanation

Bankim Chandra Chatterjee's 1882 novel Anand Math is a seminal work of Indian literature set against the historical backdrop of the Sannyasi Rebellion of the late 18th century. This rebellion was an armed conflict between the sannyasis and fakirs against the British East India Company, triggered by the Company's high revenue demands and restrictions on pilgrims following the catastrophic Bengal Famine of 1770. The novel depicts these ascetics as warrior-monks fighting for the liberation of their motherland, and it is famously known for introducing the song Vande Mataram, which became a rallying cry for the Indian independence movement.

Explanation

The Hali system was a form of hereditary bonded labor prevalent in the Surat and Valsad districts of Gujarat. Under this traditional arrangement, agricultural laborers, primarily from the Dubla or Halpati communities, were permanently attached to the landowning families of castes such as the Anavil Brahmins and Patidars. These laborers were called Halis and were bound to serve their masters in exchange for loans taken for major life events, most commonly marriage expenses. Because the wages were extremely low and interest rates high, the debt was rarely cleared, resulting in the labor obligation being passed down through generations. This created a permanent state of servitude and debt bondage within the rural agrarian structure.

Explanation

Pheromones are chemical substances produced and released into the environment by an animal, which affect the behavior or physiology of other members of the same species. These chemical signals serve as a primary mode of communication across many taxa, but they are most famously and extensively utilized by insects. Insects produce pheromones through specialized exocrine glands to facilitate a wide range of social and reproductive behaviors. For instance, sex pheromones are used to attract mates over long distances, trail pheromones allow colony members to locate food sources, and alarm pheromones warn the group of potential threats. Because insects often rely more on chemical sensing than on sight or sound, the production and reception of these molecules are fundamental to their survival and complex social structures.

Explanation

Minerals are categorized as exhaustible resources because they are finite natural substances that take millions of years to form and cannot be replaced once they are extracted and used.

Solar energy is an inexhaustible resource because it is a renewable energy source derived from the sun that remains available regardless of human consumption.

Biogas is a mixture of gases, primarily methane (CH₄) and carbon dioxide (CO₂), which are produced by the anaerobic decomposition of organic matter by bacteria.

Deforestation leads to a decrease in rainfall because trees release moisture into the atmosphere through transpiration, a process essential for cloud formation and precipitation.

Explanation

Biogas plants utilize the process of anaerobic digestion to break down organic matter such as cattle dung, agricultural waste, and food scraps. This biological decomposition produces biogas, a mixture primarily composed of methane and carbon dioxide, which can be used as a renewable energy source for cooking, heating, or generating electricity (power). Additionally, the residual byproduct of this process is a nutrient-dense slurry known as digestate. This fermented slurry is rich in nitrogen, phosphorus, and potassium, serving as a high-quality organic manure that enhances soil structure and provides essential nutrients for plant growth.

Explanation

Chandragupta II, also known as Vikramaditya, was a devout follower of Vaishnavism and is historically recognized as the first Gupta emperor to adopt the title Parama Bhagawat. This title, which translates to Great Devotee of Lord Vishnu, is found inscribed on his gold coinage and several stone inscriptions. His religious inclination is further confirmed by the Mehrauli Iron Pillar inscription, which identifies him as a king named Chandra who established a Vishnudhvaja on the Vishnupada hill as a mark of his devotion. This adoption of the title reflected the official patronage of the Bhagavata cult by the Gupta state during his reign.

Explanation

Swami Sahajanand Saraswati was the founder and first president of the All India Kisan Sabha, which was established in April 1936 during the Lucknow session of the Indian National Congress. A prominent peasant leader who had earlier founded the Bihar Provincial Kisan Sabha in 1929, he played a crucial role in mobilizing the peasantry across India against the exploitative zamindari system and high land revenue demands. The formation of this national organization marked a significant shift in the Indian national movement, as it sought to integrate the specific grievances of the agrarian classes into the broader struggle for independence. N.G. Ranga was elected as the first General Secretary alongside Swami Sahajanand Saraswati to lead the movement.

Explanation

The World Health Organization (WHO) report of 2008, particularly associated with the theme Protecting Health from Climate Change, identified 15 distinct categories of diseases and health impacts aggravated by global warming. These health risks encompass a wide range of conditions, including vector-borne diseases like malaria and dengue, water-borne illnesses such as cholera and various diarrheal diseases, and health issues related to malnutrition and heatwaves. The assessment highlighted how shifts in temperature and rainfall patterns facilitate the spread of these 15 specific categories, primarily affecting vulnerable populations in developing nations with limited healthcare infrastructure.

Explanation

Jatropha curcas is a drought-resistant perennial plant that produces seeds containing high levels of non-edible oil, typically ranging from 30% to 40%. This oil can be converted into biodiesel through the process of transesterification, where the triglycerides in the oil react with an alcohol like methanol to produce methyl esters. As a hardy crop that can thrive in marginal and wasteland conditions with minimal water and nutrients, Jatropha was identified as a primary feedstock for Indias National Policy on Biofuels. It provides a renewable energy source that does not compete with food crops for fertile land, making it an ideal candidate for sustainable fuel production.

Explanation

The Chipko movement was a non-violent social and ecological protest that began in the early 1970s in the Garhwal Himalayas of Uttarakhand. It aimed at plant preservation by preventing the mass felling of trees by commercial contractors. The movement is famous for its unique method of resistance where local villagers, particularly women like Gaura Devi, hugged the trees to protect them from being cut down. Prominent leaders like Sunderlal Bahuguna and Chandi Prasad Bhatt used the movement to raise awareness about the ecological importance of forests and the necessity of preserving natural vegetation for environmental stability and local livelihoods. This movement successfully influenced forest policy in India and highlighted the vital link between environmental conservation and community rights.

Explanation

The Wildlife Protection Act was enacted by the Parliament of India in 1972 to provide a legal framework for the protection of various species of wild animals, birds, and plants. Coming into force on 9 September 1972, this legislation was designed to ensure ecological and environmental security by prohibiting the hunting of endangered species and regulating the trade in wildlife and wildlife products. The Act categorises protected species into six schedules, offering varying degrees of protection, and provides for the establishment of protected areas such as National Parks and Wildlife Sanctuaries. It remains the primary statute governing wildlife conservation and management in India.

Explanation

International Ozone Day, officially known as the International Day for the Preservation of the Ozone Layer, is observed annually on 16th September. This date was designated by the United Nations General Assembly in 1994 to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer, which took place on 16th September 1987. The protocol is a landmark international treaty designed to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances. The observance serves to raise global awareness about the importance of the ozone layer in shielding the Earth from harmful ultraviolet radiation and highlights the progress made in its recovery through international cooperation.

Explanation

The Western Ghats is recognized as one of the world's eight hottest hotspots of biological diversity and is a UNESCO World Heritage site. This mountain range runs parallel to the western coast of the Indian peninsula and is characterized by exceptionally high levels of species richness and endemism. It serves as a home to thousands of species of flowering plants, mammals, birds, amphibians, and reptiles, many of which are found nowhere else on Earth. The high annual rainfall from the southwest monsoon supports dense tropical evergreen forests and diverse ecosystems, making it a primary biodiversity saturated area in India.

Explanation

Habitat destruction is the most significant driver of biodiversity loss globally because it results in the direct removal of the physical environment where species live, feed, and reproduce. Human activities such as large-scale deforestation for agriculture, urban expansion, and industrial development lead to the complete clearance of diverse ecosystems. When a habitat is destroyed, the carrying capacity of the land for its original inhabitants is eliminated, leading to immediate population declines and eventual extinction. Furthermore, the fragmentation of large habitats into smaller, isolated patches prevents the movement of migratory species and restricts the gene flow necessary for maintaining healthy populations. Since tropical rainforests and coral reefs, which harbor the highest concentrations of biodiversity, are particularly vulnerable to these land-use changes, habitat loss remains the primary threat to global biological variety.

Explanation

The Royal Botanic Gardens at Kew, England, is recognized as the largest and most comprehensive botanical garden in the world. Spanning approximately 132 hectares or 330 acres, it maintains the world's largest collection of living plants, with over 50,000 different species. Beyond its physical size, Kew is a premier global center for botanical research and houses a herbarium containing more than 7 million specimens. It was established in 1840 and has been a UNESCO World Heritage site since 2003, serving as a critical institution for plant conservation and taxonomic studies.

Explanation

The Western Ghats harbor extensive tropical evergreen forests primarily along their western windward slopes. These regions receive high annual rainfall, typically exceeding 200 cm, and maintain a warm, humid climate with a short dry season. The heavy orographic precipitation provided by the South-West Monsoon supports a dense, multi-layered canopy where various tree species shed their leaves at different times of the year, ensuring the forest remains green year-round. This high moisture availability and consistent temperature make the Western Ghats one of the most significant regions for evergreen vegetation and biodiversity in India.

Explanation

Uttar Pradesh consistently holds the largest area under sugarcane cultivation in India, accounting for nearly 45 to 50 percent of the total national acreage. The state's dominance is supported by the fertile alluvial soil of the Indo-Gangetic plains and an extensive irrigation network that facilitates water-intensive crops. Data from the Ministry of Agriculture for the period leading up to 2015 shows that Uttar Pradesh maintained over 2 million hectares of land for sugarcane, which is significantly higher than any other state. This large-scale cultivation forms the backbone of the state's rural economy and supports one of the highest numbers of sugar mills in the country.

Explanation

The Chorabari Lake, also known as Gandhi Sarovar, is a glacial lake located approximately 2 km upstream from the Kedarnath shrine at an altitude of about 3,960 meters. During the extreme weather events of June 2013, the region experienced intense rainfall and rapid snowmelt. This led to the overfilling of the lake, causing its natural moraine dam to breach on the morning of June 17, 2013. This Glacial Lake Outburst Flood (GLOF) released a massive surge of water and debris into the Mandakini river, which flows directly past Kedarnath. This sudden burst was the primary driver of the catastrophic flash flood that destroyed the town of Kedarnath and caused widespread devastation downstream along the Mandakini valley.

Explanation

Biodiversity refers to the variety and variability of life on Earth and the ecological complexes in which they occur. Its most significant aspect is the maintenance of the ecosystem, as biodiversity drives the essential processes that sustain life. These ecosystem services include nutrient cycling, pollination, soil fertility, carbon sequestration, and the regulation of water and climate. A diverse range of species ensures ecosystem stability and resilience, allowing natural systems to withstand and recover from environmental stresses. By maintaining these functional balances, biodiversity provides the foundational support system upon which all other biological and economic benefits depend.

Explanation

Lichens are highly sensitive bioindicators used to monitor air quality, particularly the presence of sulfur dioxide (SO₂). As symbiotic organisms composed of fungi and algae, they lack a protective cuticle and a root system, meaning they absorb water and nutrients directly from the atmosphere. This physiological trait causes them to accumulate airborne pollutants rapidly, which disrupts their metabolic processes. Consequently, lichens do not grow in areas with high levels of atmospheric pollution, and their absence or stunted growth in a specific region serves as a reliable indicator of poor air quality.

Explanation

Solar cells convert sunlight directly into electricity through the photovoltaic effect. During their operational phase, they produce no greenhouse gas emissions, such as carbon dioxide, and no toxic pollutants like sulfur dioxide or nitrogen oxides. By harnessing a virtually inexhaustible and renewable resource, solar cells provide a sustainable energy solution that helps reduce the overall carbon footprint and prevents air and water pollution. This makes them highly effective in maintaining a clean environment compared to sources that involve combustion or produce hazardous waste.

Explanation

The Yamuna river is ecologically described as a dead river in the 600-kilometer stretch between Delhi and Agra because it lacks the dissolved oxygen necessary to support aquatic life. This condition arises due to the heavy extraction of fresh water at the Hathnikund barrage for irrigation and drinking, combined with the massive discharge of untreated domestic sewage and industrial effluents from urban centers. During the non-monsoon months, the natural flow of the river is virtually non-existent, leaving only wastewater in the channel.

However, the Yamuna is geographically a perennial river. It originates from the Yamunotri Glacier on the Banderpooch peaks of the Lower Himalayas. Since it is fed by snowmelt during the summer and by monsoon rainfall during the wet season, it maintains a continuous flow throughout the year, distinguishing it from seasonal or non-perennial rivers found in the peninsular region of India.

Explanation

According to the 2011 Census, Uttar Pradesh recorded a male literacy rate of 77.28 percent and a female literacy rate of 57.18 percent. The difference between these two figures is 20.10 percentage points, which is the highest gender gap in literacy for the states in this comparison. This gap is considerably higher than the national average gender gap of 16.3 percentage points, reflecting a substantial lag in female education relative to male education in the state.

Explanation

Barren Island, situated in the Andaman Sea, is the only confirmed active volcano in India and the wider South Asian region. It is part of the volcanic arc that extends from Sumatra to Myanmar, created by the subduction of the Indian Plate beneath the Burmese Plate. The island is characterized by a central volcanic cone and a large caldera. While it remained dormant for about 150 years, it resumed activity in 1991 and has experienced several eruptive episodes since then. Geologically, it stands out from the predominantly sedimentary and coral-based islands of the Andaman and Nicobar archipelago due to its igneous composition and ongoing geothermal activity.

Explanation

Madhya Pradesh is widely recognized as the Soyabean State of India because it historically accounts for the largest share of the country's total soybean production. Up until 2015, the state frequently produced more than half of India's total output, supported by the extensive cultivation in the Malwa region. The prevalence of black soil, which possesses excellent moisture-retention properties, combined with favorable monsoon cycles, makes the state highly conducive for this oilseed crop. Data from the Ministry of Agriculture for the years preceding 2015 confirmed that Madhya Pradesh's contribution consistently exceeded the 50 percent threshold, establishing it as the powerhouse of the Indian soybean industry.

Explanation

The Rajghat Dam is a massive inter-state dam project constructed on the Betwa River, which is a major tributary of the Yamuna River. This project is a joint venture between the state governments of Uttar Pradesh and Madhya Pradesh. Located approximately 22 kilometers from Lalitpur in Uttar Pradesh, the dam serves the dual purpose of providing irrigation to the water-stressed Bundelkhand region and generating hydroelectric power. The reservoir formed by the dam is officially named Rani Laxmibai Sagar. The construction and management of the project are overseen by the Betwa River Board, which was established under the Betwa River Board Act of 1976.

Explanation

The Godavari river is the largest river of Peninsular India and the second longest river in the country after the Ganga. Originating from the Western Ghats at Trimbakeshwar in Maharashtra, it flows across the Deccan Plateau for approximately 1465 kilometers. Due to its immense size, extensive drainage basin, and the high level of spiritual reverence it commands in South India, it is traditionally referred to as Dakshina Ganga or the Ganga of the South. Its basin covers large parts of Maharashtra, Madhya Pradesh, Chhattisgarh, Odisha, Telangana, and Andhra Pradesh, making it the most significant river system in the southern region in terms of both geography and culture.

Explanation

The Coromandel Coast is the name given to the southeastern coastline of the Indian subcontinent, specifically spanning the region between the Krishna River delta in the north and Cape Comorin (Kanyakumari) in the south. This coastal strip lies between the Eastern Ghats and the Bay of Bengal, covering parts of the states of Tamil Nadu and Andhra Pradesh. It is a broad coastal plain featuring the deltas of significant rivers like the Kaveri, Penner, and Palar. Geographically, it is distinct for receiving substantial rainfall during the retreating monsoon season, which differentiates its climatic pattern from the rest of the country.

Explanation

Mount Cotopaxi is an active stratovolcano situated in the Andes range of Ecuador. It stands at an elevation of approximately 5,897 meters (19,347 feet) above sea level. It is frequently cited as one of the world's highest active volcanoes and is distinguished by its nearly symmetrical cone and significant glacial cover. Located in the Cordillera Oriental, the volcano's height is a result of long-term volcanic activity along the subduction zone of the Nazca and South American plates. The mountain has a base diameter of about 23 kilometers and its summit is one of the highest points in the Ecuadorian Andes.

Explanation

Lake Baikal is widely known as the Pearl of Siberia due to its breathtaking beauty, crystal-clear waters, and ecological significance. Located in the southern part of Eastern Siberia, Russia, it is the deepest and oldest freshwater lake in the world, estimated to be around 25 to 30 million years old. It holds approximately 20 percent of the world's unfrozen surface fresh water and is home to a vast array of endemic species, such as the Baikal seal. Its designation as a UNESCO World Heritage site in 1996 further highlights its status as a natural treasure of the Siberian region.

Explanation

The electronics industry is categorized as a footloose industry because its location is not significantly constrained by the proximity to raw materials. Since the components used in electronics, such as semiconductors, transistors, and integrated circuits, are high-value and low-weight, the cost of transporting them is a minimal part of the total production cost. Consequently, these industries are primarily influenced by other factors such as the availability of a highly skilled and technical workforce, proximity to research and development hubs, access to sophisticated infrastructure, and connectivity to major urban markets. This allows the industry to be located in diverse areas, often prioritizing regions with advanced telecommunications and stable power supplies rather than natural resource deposits.

Explanation

The title Queen of the Adriatic Sea is the famous epithet for Venice, Italy. This designation reflects the historical status of Venice as a powerful maritime republic that dominated trade and naval affairs in the Adriatic and Mediterranean regions for centuries. Venice is uniquely constructed on a group of islands within the Venetian Lagoon, whereas Rome is located further inland on the banks of the Tiber River and is primarily known by the epithet the Eternal City.

Explanation

Canada possesses the world's longest coastline, measuring approximately 202,080 kilometers. This extraordinary length is primarily due to the country's vast and complex geography, which includes an extensive network of over 36,000 islands within the Arctic Archipelago. The coastline is characterized by a highly irregular shape with numerous deep fjords, bays, and inlets spanning three oceans: the Pacific to the west, the Atlantic to the east, and the Arctic to the north. The combination of its massive continental perimeter and the intricate shorelines of its northern islands makes its total coastal length significantly greater than that of any other nation.

Explanation

The indigenous peoples of North America are anthropologically classified as part of the Mongoloid racial group. This classification is based on shared physical and genetic characteristics that link them to populations in East and Central Asia. Scientific evidence, including dental morphology such as shovel-shaped incisors and specific DNA markers, confirms that these groups migrated from Northeast Asia across the Beringia land bridge during the late Pleistocene epoch. Their physical traits, including high cheekbones, straight black hair, and specific skin pigmentation, align with the broader Mongoloid branch of human ancestry that dispersed across the Americas following their crossing from Siberia.

Explanation

Article 123 of the Indian Constitution grants the President of India the legislative power to promulgate ordinances during the recess of Parliament. This power is invoked when both Houses or either House of Parliament is not in session and the President is satisfied that circumstances exist which render it necessary to take immediate action. An ordinance promulgated under this Article possesses the same legal force and effect as an Act of Parliament. However, every such ordinance must be laid before both Houses of Parliament and ceases to operate at the expiration of six weeks from the reassembly of Parliament, or sooner if resolutions disapproving it are passed by both Houses. This mechanism ensures that the executive can address urgent legislative needs when the legislature is unavailable, while maintaining parliamentary oversight.

Explanation

Equality before Laws (A) corresponds to Article 14 (3) which guarantees that the State shall not deny any person equality before the law or equal protection of the laws within the territory of India. Right of Work (B) corresponds to Article 41 (4) which directs the State to make effective provisions for securing the right to work, education, and public assistance in cases of unemployment, old age, or sickness. Just and Humane conditions of work (C) corresponds to Article 42 (1) as it mandates the State to make provisions for securing humane conditions of work and maternity relief. Free and compulsory education for children (D) corresponds to Article 45 (2) which, as a Directive Principle, requires the State to endeavor to provide early childhood care and education for children.

Explanation

Australia has consistently been the global leader in bauxite production for several decades, a status it maintained through the mid-2010s. According to data from the United States Geological Survey (USGS) available in 2015, Australia's annual production significantly exceeded that of any other nation, accounting for nearly one-third of the total global output. The country possesses massive, high-grade reserves that are relatively easy to extract via large-scale open-cut mining operations. Major production centers are located in the Darling Range of Western Australia, Weipa in Queensland, and the Gove Peninsula in the Northern Territory. These deposits provide the essential raw material for both domestic alumina refining and international export markets, ensuring Australia's position as the primary global supplier of the ore during this period.

Explanation

The moniker Land of Morning Calm is the English translation of the name Chosun (Joseon), which was the official name of the Korean kingdom for over five centuries. The name is composed of the Chinese characters Cho, meaning morning, and Sun, meaning fresh, serene, or calm. This poetic title was popularized in the Western world by Percival Lowell, an American astronomer and diplomat, who published a book titled Chosön, the Land of the Morning Calm in 1885 after his travels to the peninsula. The name captures the serene natural beauty of Korea's landscape, particularly the tranquility found in its mountains and waters during the early morning hours.

Explanation

Australia possesses the largest share of the world's identified uranium resources. According to data from the International Atomic Energy Agency (IAEA) and the OECD Nuclear Energy Agency available in 2015, Australia held approximately 31% of the global recoverable uranium reserves, totaling over 1.7 million tonnes. This significant lead is primarily due to the presence of the Olympic Dam mine in South Australia, which is the single largest known uranium deposit on the planet. These figures represent Reasonably Assured Resources (RAR) recoverable at costs of less than $130 per kilogram of uranium.

Explanation

The Right to Information is classified as a legal right in India because it is a statutory right specifically conferred upon citizens by the Right to Information Act, 2005. This legislation, enacted by the Parliament of India, provides a formal legal framework that outlines the obligations of public authorities and defines the procedures through which individuals can access information. Rights that are created, defined, and protected by a specific Act of Parliament are categorized as legal or statutory rights, as they possess a dedicated enforcement mechanism, including the establishment of Information Commissions to adjudicate disputes and ensure compliance with the law.

Explanation

Under Article 103 of the Constitution of India, if any question arises as to whether a member of either House of Parliament has become subject to any of the disqualifications mentioned in Article 102(1), the question is referred to the President of India, whose decision is final. Article 103(2) further stipulates that before giving any decision on such a question, the President must obtain the opinion of the Election Commission of India and is constitutionally bound to act according to that opinion. This procedure applies to disqualifications related to criteria such as holding an office of profit, being of unsound mind, or being an undischarged insolvent.

Explanation

Chandra Shekhar served as the 8th Prime Minister of India from November 1990 to June 1991. Throughout his tenure as Prime Minister, he was an elected member of the 9th Lok Sabha, representing the Ballia constituency in Uttar Pradesh. He was a veteran politician often referred to as the Young Turk and led a minority government with the external support of the Indian National Congress. While the Indian Constitution allows a Prime Minister to be a member of either house of Parliament, Chandra Shekhar held his seat in the lower house during his premiership.

Explanation

Atul Gupta, a retired 1974-batch Indian Administrative Service officer and former Chief Secretary of Uttar Pradesh, served as the chairman of the fourth State Finance Commission. The commission was constituted by the Governor of Uttar Pradesh under the provisions of Article 243-I and 243-Y of the Constitution of India. Its primary mandate was to review the financial position of the Panchayats and Municipalities and provide recommendations regarding the distribution of the net proceeds of taxes, duties, tolls, and fees between the State and the local bodies. The fourth commission was tasked with providing a framework for fiscal devolution for the period of 2011 to 2016 to strengthen the resource base of local self-government institutions in the state.

Explanation

The State Finance Commission is a constitutional body because it is established under the specific provisions of the Constitution of India. Articles 243-I and 243-Y, which were inserted by the 73rd and 74th Constitutional Amendment Acts of 1992, mandate the Governor of every state to constitute a Finance Commission at the expiration of every fifth year. These commissions are tasked with reviewing the financial position of Panchayats and Municipalities and making recommendations to the Governor regarding the principles that should govern the distribution of taxes, duties, tolls, and fees between the State and the local bodies, as well as the grants-in-aid to be provided from the Consolidated Fund of the State.

Explanation

Purno Agitok Sangma was the first tribal member to serve as the Speaker of the Lok Sabha. He held the office during the 11th Lok Sabha from 1996 to 1998. A veteran leader from the state of Meghalaya, he belonged to the Garo community, which is one of the major Scheduled Tribes of Northeast India. His unanimous election to the post was a significant milestone in Indian parliamentary history, marking the first time a representative from a tribal background presided over the lower house of the Parliament.

Explanation

The Eleventh Schedule of the Indian Constitution was added by the 73rd Constitutional Amendment Act, 1992. It contains 29 functional subjects that are placed within the purview of Panchayati Raj Institutions. These subjects include essential rural development areas such as agriculture, land improvement, minor irrigation, animal husbandry, fisheries, social forestry, small-scale industries, and rural housing. Under Article 243G, the state legislatures may endow the Panchayats with such powers and authority as may be necessary to enable them to function as institutions of self-government. This schedule facilitates the decentralization of administrative and financial powers to the grassroots level to ensure economic development and social justice in rural India.

Explanation

Lord Ripon, who served as the Viceroy of India from 1880 to 1884, is hailed as the Father of Local Self Government because of his famous Resolution of 1882. This resolution provided for the development of local bodies like municipal committees and district boards to manage local affairs such as sanitation, education, and health. Ripon believed that local self-government was primarily an instrument of political and popular education. He advocated for these bodies to have a majority of non-official members, ideally elected by the people, and for the government to exercise control from without rather than within. His initiatives laid the structural groundwork for the evolution of democratic decentralization in India.

Explanation

The Assertion is false because the power of the Parliament to amend the Constitution under Article 368 is not absolute. In the landmark Kesavananda Bharati case (1973), the Supreme Court of India propounded the Basic Structure Doctrine, which stipulates that the Parliament cannot use its amending power to alter or destroy the fundamental features or the basic structure of the Constitution. Consequently, while the Parliament can amend most parts of the Constitution, it cannot amend any part that constitutes the basic framework of the document. The Reason is true as the Parliament of India is the highest legislative organ of the Union, representing the sovereign will of the people. It is the primary law-making body at the national level, consisting of the President and two Houses, with the members of the Lok Sabha being directly elected by the people of India.

Explanation

Article 40 of the Constitution of India, located within the Directive Principles of State Policy, directs the State to take active steps to organize village panchayats. It further mandates that these bodies be endowed with the necessary powers and authority to function as independent units of self-government. This article reflects the Gandhian philosophy of decentralization and grassroots democracy, known as Gram Swaraj, which advocates for the empowerment of rural communities. The spirit of this constitutional directive eventually led to the passage of the 73rd Constitutional Amendment Act in 1992, which granted constitutional status and a structured framework to the Panchayati Raj system across India.

Explanation

According to Article 243-I of the Constitution of India, established via the 73rd Constitutional Amendment Act of 1992, the Governor of a state is authorized to constitute a State Finance Commission every five years. The primary mandate of this commission is to review the financial status of Panchayati Raj Institutions and make recommendations regarding the distribution of net proceeds of taxes, duties, tolls, and fees between the state government and the Panchayats. It also advises on the principles for determining grants-in-aid to Panchayats from the Consolidated Fund of the State and suggests measures needed to improve their financial position. The Governor is further required to place the commission's reports and the action-taken report before the state legislature.

Explanation

Article 155 of the Constitution of India provides for the appointment of the Governor of a State. According to this article, the Governor shall be appointed by the President by warrant under his hand and seal. This signifies that the Governor is not elected, either directly or indirectly, but is a nominee of the Central Government, serving at the pleasure of the President. This constitutional provision ensures a link between the Union and the State governments, maintaining the unitary spirit within the federal structure of the Indian polity.

Explanation

Article 76(3) of the Constitution of India explicitly states that the Attorney General, in the performance of his duties, shall have the right of audience in all courts in the territory of India. As the highest law officer in the country and the chief legal advisor to the Government of India, this constitutional provision ensures that the Attorney General can represent the Union Government in any judicial forum across the nation, regardless of the jurisdiction or the level of the court. This right is fundamental to the office's responsibility of handling legal matters of national importance and protecting the interests of the Union throughout the Indian territory.

Explanation

The Constitution of India is the longest written constitution in the world, a status resulting from the integration of both Union and State provisions, detailed administrative procedures, and the influence of the Government of India Act 1935. The framers sought to provide specific solutions for India's diverse population, including provisions for scheduled castes, scheduled tribes, and official languages, which expanded the document's size. Simultaneously, the chapter on Fundamental Rights in Part III was modeled after the Bill of Rights of the American Constitution. While both statements are accurate, the act of borrowing the Fundamental Rights model does not explain the overall length of the Indian Constitution, as the American document is notably concise. The expansion of the Indian text was driven by structural and administrative necessity rather than the inclusion of rights alone.

Explanation

The Indrajit Gupta Committee was an eight-member committee constituted by the Government of India in 1998 to examine the feasibility of state funding of elections. Its primary mandate was to suggest measures for electoral reforms, specifically focusing on how the state could provide financial support to political parties to reduce the influence of private money and ensure fair competition during elections. Unlike bodies established to review the constitutional, legislative, and administrative framework between the central government and the states, this committee was strictly focused on the electoral process and democratic integrity.

Explanation

The Indian Constitution adopted the concept of the Preamble from the Constitution of the United States of America. The U.S. Constitution was the first in the world to feature a Preamble, serving as an introductory statement that outlines the document's guiding purpose and principles. In India, while the Preamble's content was heavily influenced by the Objective Resolution drafted and moved by Jawaharlal Nehru in 1946, the structural decision to incorporate a Preamble at the beginning of the supreme law was a direct borrowing from the American constitutional tradition. It functions as an introduction to the Constitution, embodying the source of authority and the fundamental socio-political values of the Indian state.

Explanation

The 44th Amendment Act of 1978 modified Article 359 of the Indian Constitution to ensure that the enforcement of the rights guaranteed by Articles 20 and 21 cannot be suspended by the President even during a National Emergency. Article 20 provides protection in respect of conviction for offences, which includes immunity against retrospective criminal laws, double jeopardy, and self-incrimination. Article 21 protects the right to life and personal liberty, stipulating that no person shall be deprived of these rights except according to the procedure established by law. This amendment was introduced to provide a safeguard against the absolute suppression of civil liberties and to ensure that the basic right to judicial remedy for life and liberty remains intact during emergency periods.

Explanation

The Supreme Court of India described the Central Bureau of Investigation as a caged parrot speaking in its master's voice during the hearing of the Coal Block Allocation scam case, also known as the Coal Gate scam, in May 2013. A three-judge bench headed by Justice R.M. Lodha made this observation after it was revealed that the then Law Minister and officials from the Prime Minister's Office and the Coal Ministry had vetted and significantly altered the CBI's status report before it was submitted to the court. The court pulled up the agency for allowing political interference, stating that the CBI's independence had been compromised and that it must be insulated from the influence of the executive to function as an impartial investigative body.

Explanation

Prime Minister Narendra Modi announced the decision to abolish the Planning Commission during his maiden Independence Day speech on August 15, 2014. The body, which was established in 1950 to oversee India's Five-Year Plans, was replaced by the NITI Aayog (National Institution for Transforming India) on January 1, 2015. This change was aimed at shifting from a centralized, top-down planning model to a framework of cooperative federalism, emphasizing a bottom-up approach where state governments play a more significant role in the policy-making process and national development agenda.

Explanation

National Voters Day has been celebrated across India on 25th January every year since 2011. This specific date was chosen to mark the foundation day of the Election Commission of India, which was established on 25th January 1950. The initiative was launched by the Government of India to increase the enrollment of voters, especially among the youth, and to spread awareness about the importance of exercising the right to vote in a democracy. The day is utilized to sensitize citizens about their electoral rights and to facilitate the registration of new eligible voters who have turned 18.

Explanation

The Pivot to Asia, also known as the rebalance to the Asia-Pacific, was a central strategic shift in the foreign policy of the United States under the administration of President Barack Obama. Formally articulated by Secretary of State Hillary Clinton in late 2011, the policy sought to transition the focus of American diplomatic, economic, and military resources from the Middle East and Europe toward the Asia-Pacific region. This reorientation was based on the recognition that the future of global politics and economics would be increasingly centered in Asia. Key components of the strategy included strengthening bilateral security alliances, deepening relationships with emerging powers, engaging with regional multilateral institutions, and expanding trade and investment through initiatives like the Trans-Pacific Partnership.

Explanation

Muhammad Ali Jinnah was a prominent critic of the Khilafat Movement rather than a participant or leader. The movement, which aimed to restore the status of the Ottoman Caliph as a religious and political leader, was led by the Ali brothers (Shaukat Ali and Mohammad Ali Jinnah's namesake, Maulana Mohammad Ali Jauhar), Maulana Abul Kalam Azad, and Hakim Ajmal Khan. Jinnah strongly opposed the inclusion of religious issues in the political struggle for independence and disagreed with Mahatma Gandhi’s strategy of merging the Khilafat cause with the Non-Cooperation Movement. This ideological rift and his opposition to the use of mass mobilization based on religious sentiments led to his resignation from the Indian National Congress at the Nagpur Session in 1920.

Explanation

The Constitution of India provides for single citizenship for the whole of India to promote national integration and a sense of fraternity among its people. Under Articles 5 to 11 and the Citizenship Act of 1955, every person is a citizen of India only, regardless of the state in which they reside or were born. This uniform citizenship ensures that all citizens enjoy the same political and civil rights throughout the territory of India. By establishing a single national identity, the Indian federal system seeks to eliminate regionalism and communalism, ensuring that an individual owes allegiance solely to the Union of India rather than to a specific state or province.

Explanation

Article 51A was inserted into the Indian Constitution by the 42nd Constitutional Amendment Act in 1976. This addition followed the recommendations of the Swaran Singh Committee, which suggested that a chapter on fundamental duties should be included to ensure that citizens are aware of their obligations while enjoying their fundamental rights. Contained within the newly created Part IV-A, Article 51A originally listed ten fundamental duties, such as upholding the sovereignty and integrity of India, promoting harmony, and safeguarding public property. These provisions were intended to strengthen the social fabric and instill a sense of civic responsibility among the citizenry.
