SSC CGL Tier 1 2017 General Awareness Questions with Solutions

Explanation

The Charter Act of 1813 abolished the trade monopoly of the East India Company in India, opening up Indian trade to all British merchants. This shift was primarily a result of the growing influence of Adam Smith's free-trade principles and the demands of private British traders who were restricted by the Company's exclusive rights. While the Act ended the general monopoly, it allowed the Company to retain its monopoly over the tea trade and the trade with China for an additional twenty years. This legislation marked the beginning of the transition of the East India Company from a purely commercial body to a territorial and administrative power under the British Crown.

Explanation

The Battle of Buxar (1) took place in 1764 (b) between the British East India Company and the combined forces of Mir Qasim, Shuja-ud-Daula, and Shah Alam II, resulting in a victory that secured British tax-collecting rights in the Bengal region. The Battle of Plassey (2) occurred in 1757 (c) where Robert Clive's forces defeated the Nawab of Bengal, Siraj-ud-Daulah, marking the beginning of British political dominance in India. The Battle of Haldighati (3) was fought in 1576 (a) between the Rajput army led by Maharana Pratap of Mewar and the Mughal forces under Raja Man Singh I of Amber during the reign of Emperor Akbar.

Explanation

Western disturbances are extra-tropical cyclones that originate over the Mediterranean Sea and travel eastward towards the Indian subcontinent, driven by the westerly jet stream. These weather systems typically enter India from the northwest during the winter months, bringing significant rainfall and snow to the Himalayan region and the plains of northwestern India. Punjab, being situated in this geographic path, receives crucial winter precipitation from these systems. This rainfall is highly beneficial for the cultivation of Rabi crops, particularly wheat, which is a staple of the agricultural economy in the region. Since these weather systems lose their moisture as they move further east and south, their influence is most pronounced in states like Punjab.

Explanation

The Deccan Plateau receives scanty rainfall because it is situated in the rain shadow region of the Western Ghats. During the monsoon season, the moisture-laden South-West Monsoon winds from the Arabian Sea are obstructed by the high altitude of the Western Ghats. This forces the air to rise, cool, and condense, resulting in heavy orographic rainfall on the windward side and the coastal plains. By the time these winds cross the mountain peaks and descend onto the Deccan Plateau, they have lost most of their moisture. Additionally, the descending air warms up adiabatically, which increases its capacity to hold moisture and inhibits further precipitation, leaving the interior plateau relatively dry.

Explanation

The process of aerobic respiration involves the breakdown of pyruvate, which is the three-carbon molecule produced during glycolysis in the cytoplasm. In the presence of oxygen, pyruvate is transported into the mitochondria. Within the mitochondrial matrix, pyruvate undergoes oxidative decarboxylation and enters the Citric Acid Cycle (Krebs Cycle). During these stages and the subsequent electron transport chain, pyruvic acid is completely oxidized into carbon dioxide (CO₂) and water (H₂O), leading to the synthesis of a large amount of energy in the form of Adenosine Triphosphate (ATP). This complete breakdown of glucose derivatives occurs specifically within the mitochondria of eukaryotic cells.

Explanation

Plant cell walls are primarily composed of cellulose, a complex carbohydrate that provides structural support and rigidity to the cell. While cell membranes are made of lipids, the cell wall's defining structural component is cellulose.

Explanation

Power is defined as the rate at which work is performed or energy is transferred. The standard formula for power is P = (W)/(t), where W is the work done measured in Joules and t is the time taken in seconds. In the International System of Units (SI), the unit of power is the Watt, which is equivalent to one Joule per second (1 W = 1 J/s). This unit was named to honor James Watt for his significant improvements to the steam engine during the Industrial Revolution.

Explanation

Siderite is a mineral composed of iron carbonate with the chemical formula FeCO₃. It is an important ore of iron rather than a variety of coal. While coal is an organic sedimentary rock formed from the decomposition of plant matter over millions of years, siderite is an inorganic carbonate mineral. It is often found in sedimentary deposits alongside clay and other minerals but lacks the high carbon content and combustible properties that define the different stages of coal.

Explanation

A light-year is a unit of astronomical distance rather than a unit of time. It is defined as the total distance that light travels in a vacuum during one Julian year, which is approximately 9.46 × 10¹² kilometers or 5.88 × 10¹² miles. While the term contains the word year, it represents the product of the speed of light and the duration of a year, resulting in a measure of length used to describe the vast scales between celestial bodies. Consequently, pairing a light-year with time is fundamentally incorrect.

Explanation

The CDC 6600, released in 1964 and designed by Seymour Cray at Control Data Corporation, is generally recognized as the first successful supercomputer in history. It achieved a performance of approximately 3 megaflops, which was three times faster than the previous record-holder, the IBM 7030 Stretch. Its architectural innovation involved using a single central processing unit for arithmetic and logic while offloading input and output tasks to ten peripheral processors, a design that allowed it to maintain unprecedented processing speeds for its era.

Explanation

Fog, clouds, and mist are colloidal systems classified as aerosols. In these mixtures, the dispersed phase consists of tiny liquid droplets, such as water, while the dispersion medium is a gas, typically air. When liquid particles are suspended in a gaseous medium, the resulting colloid is specifically termed a liquid aerosol. These phenomena occur when water vapor in the atmosphere condenses into minute droplets that are light enough to remain suspended in the air rather than falling immediately as rain.

Explanation

Quicklime is the common name for the chemical compound calcium oxide, represented by the formula CaO. It is a white, caustic, and alkaline crystalline solid at room temperature. Quicklime is industrially produced by the thermal decomposition of limestone, which primarily consists of calcium carbonate (CaCO₃), in a process called calcination. This involves heating the material in a lime kiln to temperatures above 825°C, which drives off carbon dioxide gas and leaves behind the solid oxide. Calcium oxide is highly reactive, especially with water, where it undergoes an exothermic reaction to form slaked lime. It is a critical component in various industrial processes, including steel manufacturing, flue-gas desulfurization, and water treatment.

Explanation

Sunder Lal Bahuguna was a prominent Gandhian environmentalist and a key leader of the Chipko movement, which originated in 1973 in the Chamoli district of Uttarakhand. He played a vital role in globalizing the movement's philosophy of non-violent resistance against large-scale deforestation. His dedicated activism and long foot marches across the Himalayan region raised significant awareness about forest conservation, eventually leading to a fifteen-year ban on felling green trees in the Himalayan forests in 1980. Bahuguna is also widely recognized for his environmental philosophy summarized in the slogan Ecology is permanent economy.

Explanation

The Pradhan Mantri Digital Saksharta Abhiyan (PMGDISHA) was approved by the Union Cabinet in February 2017 as a dedicated scheme to impart digital literacy in rural India. The initiative aimed to cover 6 crore rural households by reaching out to one person from every eligible family. The government set an implementation timeline to achieve this target by March 31, 2019. The program was designed to bridge the digital divide by training citizens to operate computers or digital access devices, browse the internet, and undertake digital payments. By focusing on rural areas, the scheme sought to empower marginalized communities and enable them to participate actively in the process of e-governance and the digital economy.

Explanation

Serena Williams secured her 23rd Grand Slam singles title by defeating her sister Venus Williams 6-4, 6-4 in the 2017 Australian Open final. This victory was historic as it allowed her to surpass Steffi Graf's Open Era record of 22 major titles, leaving her just one behind Margaret Court's all-time record of 24. Remarkably, it was later revealed that Serena was approximately eight weeks pregnant during the tournament. This win also ensured her return to the world number one spot in the WTA rankings.

Explanation

The International Yoga Fest was organized by the Ministry of AYUSH from March 8 to 10, 2017, at the Talkatora Indoor Stadium in New Delhi. This three-day event served as a curtain-raiser for the 3rd International Day of Yoga. It was inaugurated by the Union Minister of State for AYUSH and featured a wide range of activities, including mass yoga demonstrations, technical sessions, and workshops led by prominent yoga gurus and scholars. The festival aimed to promote the ancient Indian practice of yoga for holistic health and well-being while preparing for the nationwide celebrations held annually on June 21.

Explanation

The Filmfare Lifetime Achievement Award for the year 2017 was conferred upon veteran actor and politician Shatrughan Sinha at the 62nd Filmfare Awards ceremony held in January. Known for his distinctive voice and powerful dialogue delivery, Sinha began his career in the late 1960s and achieved great success as both a formidable antagonist and a popular leading hero in numerous Hindi films. This award recognized his prolific contribution to Indian cinema spanning several decades. His journey from a supporting actor to one of the most recognizable stars of the 1970s and 1980s made him a significant figure in the industry, earning him this prestigious recognition for his long-standing career and artistic impact.

Explanation

The Windfall, published in 2017, is the debut novel written by Diksha Basu. The story is a social satire that follows the Jha family as they navigate a sudden change in their socio-economic status. After selling his business for a large sum of money, the protagonist, Mr. Jha, decides to move his family from their modest housing in East Delhi to a glitzy, affluent neighborhood in Gurgaon. The book explores themes of class anxiety, the complexities of new wealth, and the shifting cultural landscape of contemporary India. Diksha Basu, an author and actor based in New York and Mumbai, received widespread acclaim for her humorous and insightful portrayal of the Indian middle class's aspirations.

Explanation

China hosted the 9th BRICS Summit in 2017 in Xiamen, Fujian Province. The hosting of BRICS summits follows a rotational sequence based on the acronym B-R-I-C-S. Following India's presidency and the 8th summit in Goa in 2016, China assumed the rotating chairmanship for the 2017 calendar year. The summit took place from September 3 to September 5 under the theme Stronger Partnership for a Brighter Future. During this summit, the BRICS Plus cooperation approach was introduced to strengthen ties between BRICS members and other developing nations.

Explanation

In December 2016, India and Bhutan signed a Memorandum of Understanding (MoU) to enhance technical cooperation in the field of infrastructure engineering. This agreement specifically focused on promoting green and sustainable construction practices within the Himalayan Kingdom. Under this partnership, India provided technical assistance through its Central Public Works Department (CPWD) to the Department of Engineering Services of Bhutan. The collaboration was designed to share expertise in energy-efficient building technologies, earthquake-resistant design, and environmental conservation, aligning with Bhutan's constitutional commitment to maintaining a carbon-neutral footprint and preserving its natural environment during infrastructure development.

Explanation

In a perfect competition market structure, individual firms are price takers rather than price makers. This condition arises because the market consists of a very large number of buyers and sellers dealing in homogeneous products. Since each individual firm contributes only a negligible fraction of the total market supply, no single producer has the power to influence the market price through its own actions. The price is determined exclusively by the intersection of aggregate market demand and aggregate market supply. Because products are identical and consumers have perfect information, any firm attempting to set a price higher than the market equilibrium would lose all its customers to competitors. Consequently, the firm faces a perfectly elastic demand curve, represented as a horizontal line at the market-determined price level.

Explanation

The Lorenz Curve is a graphical representation used to show the distribution of income or wealth within a population. Developed by Max O. Lorenz in 1905, it plots the cumulative percentage of total income received against the cumulative percentage of the population, starting from the poorest individuals. In this graph, a straight 45-degree diagonal line represents a state of perfect equality, where every percentile of the population receives an equal share of the income. The extent to which the Lorenz Curve sags below this diagonal line indicates the degree of inequality in income distribution. This visual representation serves as the foundation for calculating the Gini Coefficient, which provides a single numerical value to quantify the level of inequality in a given society.

Explanation

The abolition of titles, except for military and academic distinctions, is a provision under Article 18 of the Indian Constitution. This article is part of the Fundamental Rights (Part III) under the category of Right to Equality. It mandates that the state shall not confer any titles and that no citizen of India shall accept any title from any foreign state, aimed at maintaining social equality by removing artificial distinctions. Conversely, Fundamental Duties are enshrined in Article 51A under Part IV-A, which was added by the 42nd Constitutional Amendment Act, 1976. Since Article 18 is a constitutional right and a restriction on the state, it does not fall within the list of duties prescribed for citizens.

Explanation

Article 360 of the Indian Constitution empowers the President to proclaim a Financial Emergency if they are satisfied that a situation has arisen whereby the financial stability or credit of India, or any part of its territory, is threatened. Under this provision, the executive authority of the Union extends to giving directions to any State to observe specific canons of financial propriety. This may include directives for the reduction of salaries and allowances of all or any class of persons serving in connection with the affairs of the Union or a State, including the judges of the Supreme Court and the High Courts. Additionally, the President can require that all money bills or other financial bills be reserved for their consideration after they are passed by the Legislature of the State. Such a proclamation must be laid before both Houses of Parliament and expires after two months unless approved by resolutions of both Houses.

Explanation

The Poona Pact was signed on September 24, 1932, at Yerwada Central Jail in Poona between Dr. B. R. Ambedkar and Mahatma Gandhi (represented by Madan Mohan Malaviya and other leaders while Gandhi was in prison). This historic agreement was a response to the Communal Award announced by British Prime Minister Ramsay MacDonald, which provided separate electorates for the Depressed Classes. Gandhi opposed the separate electorates as he believed they would permanently divide the Hindu community, leading him to begin a fast unto death. The pact resolved the crisis by abandoning separate electorates in favor of reserved seats for the Depressed Classes within the general electorate, substantially increasing the number of seats allocated to them in provincial legislatures.

Explanation

Lord William Bentinck enacted the Bengal Sati Regulation on December 4, 1829, which formally abolished the practice of Sati across British India. This legislative act, known as Regulation XVII, declared the practice of burning or burying alive Hindu widows illegal and punishable as culpable homicide. Bentinck was motivated by humanitarian concerns and was strongly supported by the Indian social reformer Raja Ram Mohan Roy, who provided scriptural evidence that the custom was not a mandatory religious duty. While the regulation initially applied only to the Bengal Presidency, similar laws were extended to the Madras and Bombay Presidencies by 1830.

Explanation

Hydrogen (H₂) is not classified as a primary greenhouse gas because it is a homonuclear diatomic molecule that does not possess a dipole moment. To function as a greenhouse gas, a molecule must be capable of absorbing and emitting infrared radiation, which requires a change in its dipole moment during molecular vibration. Since hydrogen molecules are symmetric and lack this property, they do not directly trap heat in the atmosphere. While hydrogen can indirectly influence the climate by reacting with hydroxyl radicals and affecting the atmospheric lifespan of other gases, it lacks the direct radiative forcing characteristics that define primary greenhouse gases.

Explanation

Tropical Deciduous Forests, also known as Monsoon Forests, are the most widespread forest type in India. They cover the largest part of the country, particularly in regions receiving annual rainfall between 70 cm and 200 cm. These forests are found extensively across the eastern slopes of the Western Ghats, the foothills of the Himalayas, the Indo-Gangetic plains, and various parts of the Deccan Plateau. They are further categorized into Moist Deciduous and Dry Deciduous forests based on the specific amount of precipitation. A key characteristic of these forests is that the trees shed their leaves for about six to eight weeks during the dry summer season to conserve water. Commercially important species such as Teak, Sal, Shisham, Sandalwood, and Khair are predominantly found in this vegetation zone.

Explanation

Blood group O- is considered the universal donor because its red blood cells lack A, B, and Rh antigens on their surface. Because these antigens are absent, the recipient's immune system does not recognize the transfused cells as foreign, which prevents an immune-mediated attack or hemolysis regardless of the recipient's blood type. This property makes O- blood essential in emergency situations where a patient's blood type is unknown and immediate transfusion is required to save a life.

Explanation

The human brain is anatomically and developmentally divided into three primary regions: the forebrain, the midbrain, and the hindbrain. The forebrain, also known as the prosencephalon, is the largest division and consists of the cerebrum, thalamus, and hypothalamus, which handle high-level cognitive functions and sensory integration. The midbrain, or mesencephalon, serves as a crucial relay center for visual, auditory, and motor system information. The hindbrain, or rhombencephalon, includes the cerebellum, pons, and medulla oblongata, which are responsible for coordinating movement and regulating essential autonomic life functions such as breathing and heart rate. These three segments together form the entire central control system of the body.

Explanation

Adrenaline, also known as epinephrine, is a hormone produced primarily by the adrenal medulla of the adrenal glands. It acts as a chemical messenger released into the bloodstream in response to physical or mental stress, fear, or excitement. This release triggers the fight-or-flight response, which involves physiological changes such as an increased heart rate, elevated blood pressure, dilation of the pupils, and the mobilization of energy through the breakdown of glycogen into glucose. Chemically, adrenaline is a catecholamine derived from the amino acids tyrosine and phenylalanine. Because it is secreted by an endocrine gland and travels through the circulatory system to affect distant target organs and tissues, it is classified as a hormone.

Explanation

Supercooling, also known as undercooling, is the physical process where a liquid is cooled to a temperature below its normal freezing point without transitioning into a solid state. This phenomenon occurs because the phase change from liquid to solid requires a nucleation site, such as a seed crystal or an impurity, around which the crystalline structure can begin to grow. In the absence of such nuclei, the liquid can remain in a metastable state well below its freezing point because the molecules, despite having low kinetic energy, lack the necessary template to arrange themselves into a rigid lattice structure.

Explanation

Refraction is the phenomenon where light changes its direction of travel as it passes from one transparent medium to another. This bending occurs because the speed of light varies depending on the optical density of the medium it is traversing. The relationship between the angle of incidence ₁ and the angle of refraction ₂ is defined by Snell Law, given as n₁ sin ₁ = n₂ sin ₂, where n₁ and n₂ are the refractive indices of the respective media. The magnitude of the change in direction depends on the ratio of these refractive indices and the angle at which the light hits the boundary between the two substances.

Explanation

A plotter is a computer hardware output device used for printing vector graphics. Instead of using dots like a traditional printer, plotters use pens, pencils, or markers to draw continuous, high-precision lines on paper. This makes them specifically suited for technical applications such as architectural blueprints, engineering designs, and map-making. Because the device receives instructions from a computer to create a physical representation of digital data, it functions as an output unit rather than an input unit.

Explanation

Phenol, with the chemical formula C₆H₅OH, is an aromatic organic compound also known as carbolic acid. It consists of a phenyl group bonded to a hydroxyl group. The name carbolic acid reflects its weak acidic nature, as it can dissociate in water to release a hydrogen ion (H⁺) and form a phenoxide ion. This acidity is higher than that of aliphatic alcohols due to the resonance stabilization of the phenoxide ion by the benzene ring. Historically, carbolic acid gained prominence in the mid-19th century when it was extracted from coal tar and utilized by Joseph Lister as the first widespread surgical antiseptic to prevent wound infections.

Explanation

J. J. Thomson discovered the electron in 1897 while conducting experiments with cathode ray tubes. He observed that cathode rays were deflected by electric and magnetic fields, indicating they were composed of negatively charged particles. By calculating the charge-to-mass ratio (e/m) of these particles, he determined they were significantly lighter than the smallest known atom, the hydrogen atom. This finding proved that atoms were not indivisible spheres but contained smaller subatomic particles, fundamentally changing the scientific understanding of atomic structure. His pioneering work earned him the Nobel Prize in Physics in 1906.

Explanation

Medha Patkar is the primary leader and founding member of the Narmada Bachao Andolan (NBA), a social movement initiated in 1985 to protest against the construction of a series of large dams across the Narmada River. Her activism focused on the Sardar Sarovar Project, where she championed the rights of the indigenous tribal populations and farmers facing displacement due to reservoir submergence. She advocated for environmental protection and demanded a comprehensive rehabilitation and resettlement policy for the affected families. Through non-violent methods such as long marches, hunger strikes, and legal petitions, she brought the social and ecological costs of large-scale dam projects to the forefront of national and international discourse.

Explanation

The Ude Desh ka Aam Nagrik (UDAN) scheme was launched by the Ministry of Civil Aviation in October 2016 as a key component of the National Civil Aviation Policy. The primary objective of this Regional Connectivity Scheme (RCS) is to facilitate affordable air travel to unserved and underserved airports in tier 2 and tier 3 cities. To achieve this, the government implemented a fare cap of Rs 2,500 per hour of flight for approximately 500 kilometers on fixed-wing aircraft. This pricing mechanism is intended to make flying accessible to the masses, with the financial gap for airlines being covered through Viability Gap Funding (VGF) financed by a small levy on flights operating on major trunk routes.

Explanation

A. Hoyt Taylor and Leo C. Young were researchers at the United States Naval Research Laboratory who are credited with the discovery of the radar principle. In 1922, while conducting experiments with high-frequency radio transmissions across the Potomac River, they observed that a wooden ship passing between the transmitter and receiver caused a noticeable interference in the signal. This phenomenon demonstrated that radio waves could be used to detect the presence of distant objects. Their continued research throughout the late 1920s and early 1930s led to the successful detection of aircraft, establishing the fundamental technology for Radio Detection and Ranging (RADAR).

Explanation

David Warner is a professional cricketer who represents the Australian national team. He is widely recognized as one of the most successful opening batsmen in the world across all formats of the game. Warner made his international debut for Australia in January 2009 in a Twenty20 International against South Africa, notably becoming the first player in 132 years to be selected for the Australian national team without having played any first-class cricket. Since then, he has been a mainstay in the Australian lineup in Test matches, One Day Internationals, and T20 Internationals, playing a pivotal role in various ICC tournaments and helping the team achieve significant success in global cricket.

Explanation

Ikebana is the traditional Japanese art of flower arrangement, also known as Kado or the way of flowers. Its origins date back to the 7th century when floral offerings were made at Buddhist altars. Unlike many Western styles that focus on the symmetry and mass of blooms, Ikebana emphasizes the minimalist beauty of lines, shape, and form. It incorporates not just the blossoms, but also the stems, leaves, and branches of plants. The practice is governed by specific rules of composition often involving a scalene triangle to represent the relationship between heaven, earth, and humanity, aiming to create a perfect harmony between nature and the viewer.

Explanation

Vishwa Mohan Bhatt is a distinguished Hindustani classical music instrumentalist from Rajasthan, widely recognized for his invention of the Mohan Veena, which is a uniquely modified slide guitar. He was honored with the Padma Bhushan in 2017 by the Government of India for his outstanding contributions to the field of Art-Music. His innovative approach to music involves integrating the depth of Indian classical ragas with the versatility of the guitar, an achievement that previously earned him a Grammy Award and international acclaim.

Explanation

An Unsuitable Boy is the autobiography of prominent Indian filmmaker and television personality Karan Johar, co-authored with Poonam Saxena. Released in January 2017, the memoir offers a candid account of Johar's life, tracing his journey from a sensitive child in South Mumbai to becoming one of the most influential figures in Bollywood. The book delves into his personal struggles, his experiences with the film industry, and his views on sexuality and relationships. The title itself is a creative play on Vikram Seth's famous novel A Suitable Boy, highlighting Johar's perspective on his own identity and public persona.

Explanation

China is designated as a Dialogue Partner of the Indian Ocean Rim Association (IORA) rather than a full member state. The association's membership is specifically reserved for sovereign states that border the Indian Ocean. Since China does not have a direct coastline on the Indian Ocean, it does not meet the fundamental geographic requirement for membership. Dialogue Partners are permitted to participate in IORA meetings and activities to support regional stability and economic cooperation, but they do not possess the same voting rights or formal membership status as the Indian Ocean rim nations.

Explanation

China operationalized the Shanghai-Kunming High-Speed Railway, which covers a total distance of 2,252 kilometers. The final section of this massive infrastructure project, linking Kunming in Yunnan Province to Guiyang in Guizhou Province, was completed and opened to the public in late December 2016, making it the most significant high-speed rail development heading into January 2017. This line passes through five provinces—Zhejiang, Jiangxi, Hunan, Guizhou, and Yunnan—effectively connecting the prosperous eastern coast with the mountainous southwestern region. The high-speed link reduced the travel time between Shanghai and Kunming from approximately 34 hours on conventional trains to about 11 hours, marking a major milestone in the expansion of the Chinese high-speed rail network, which is the largest in the world.

Explanation

In a centrally planned economy, also known as a command economy, the government or a central authority performs the role of the primary decision-maker for all major economic activities. The state determines what goods and services are produced, the quantities in which they are manufactured, and the prices at which they are distributed to the population. Instead of relying on market signals like consumer demand or the profit motive, the government allocates resources based on a centralized plan designed to meet specific social or national objectives. This top-down approach ensures that the state maintains direct control over the factors of production and the overall direction of the national economy.

Explanation

The Law of Diminishing Marginal Product is a fundamental economic principle describing the behavior of production when at least one input is fixed. In the short run, as a firm increases the quantity of a variable input while keeping other inputs constant, the marginal product—defined as the change in total output resulting from a one-unit change in the variable input, or MP = Δ TP / Δ L—will eventually decline. This occurs because the fixed factor of production becomes over-utilized or crowded by the increasing units of the variable factor, leading to a decrease in the efficiency and incremental contribution of each additional unit of input. While total output may continue to rise, the rate of increase slows down once the point of diminishing returns is reached.

Explanation

Appellate jurisdiction refers to the authority of a higher court to review, hear, and overrule the decisions of lower courts. Under the Indian Constitution, the Supreme Court serves as the ultimate court of appeal, exercising this power through Articles 132, 133, 134, and 136. When a case is brought before the Supreme Court under this jurisdiction, the court re-examines the legal issues, the application of law, and the constitutional validity of the lower court's judgment. This process allows for the reconsideration of the entire case to ensure that justice is served and that legal principles are correctly applied, potentially leading to the modification or reversal of the previous decision.

Explanation

The 15th Constitutional Amendment Act, 1963, amended Article 217 of the Constitution of India to increase the retirement age of High Court judges from 60 to 62 years. This change was implemented to retain experienced judges for a longer duration and address the increasing workload within the higher judiciary. Additionally, this amendment empowered the President of India to determine the age of a High Court judge in consultation with the Chief Justice of India, making the decision final in cases of age-related disputes.

Explanation

The British colonial administration commercialized Indian agriculture by compelling or incentivizing farmers in specific provinces to produce particular crops suited to their regional conditions and imperial needs. Under this policy, the British focused on the expansion of rice cultivation in the Madras Presidency. This was supported by the development of large-scale irrigation projects in the deltas of the Godavari and Krishna rivers, which were designed to stabilize food supplies and ensure a consistent flow of land revenue from the southern regions of India.
