SSC CGL Tier 1 2014 General Awareness Questions with Solutions

Explanation

The Third Five Year Plan (1961–1966) faced significant challenges including the Sino-Indian War of 1962, the Indo-Pakistani War of 1965, and a severe drought in 1965–1966 which led to a food shortage and economic instability. Due to these factors and the devaluation of the Indian rupee, the government was unable to finalize the Fourth Five Year Plan on schedule. As a result, the period from 1966 to 1969 was designated as a Plan Holiday, during which three independent Annual Plans were implemented to address immediate economic concerns before resuming long-term planning in 1969.

Explanation

Hind Swaraj, also known as Indian Home Rule, was written by Mahatma Gandhi in 1909 during his journey from London to South Africa. In this seminal work, Gandhi expressed his views on Swaraj, modern civilization, and mechanization, establishing the philosophical foundations of his non-violent struggle. Jawaharlal Nehru, while a prolific author, wrote books such as The Discovery of India, Glimpses of World History, and An Autobiography. Attributing the authorship of Hind Swaraj to Pundit Jawaharlal Nehru is historically incorrect as the book is exclusively the work of Mahatma Gandhi.

Explanation

The concept of the Rule of Law is a fundamental principle of the British constitutional system, famously elaborated by the British jurist A.V. Dicey in his work, Introduction to the Study of the Law of the Constitution (1885). Dicey defined the Rule of Law through three key pillars: the absolute supremacy of regular law over arbitrary power, equality before the law where all classes are subject to the ordinary law of the land administered by ordinary courts, and the fact that the constitution is the result of the ordinary law of the land rather than being the source of judicial rights. In the United Kingdom, this principle ensures that the executive exercises its authority within a legal framework and that individual liberties are protected through judicial precedents and common law traditions.

Explanation

A free market policy is based on the principle of laissez-faire, where the economy operates with minimal government or central bank intervention and prices are determined by the forces of demand and supply. Controlling the money supply is an active regulatory function performed by a central bank to maintain price stability and influence economic growth. Since a free market policy advocates for the absence of such regulatory constraints and interventions, it does not provide the mechanisms or the intent required to manage or manipulate the volume of money circulating in the economy. Effective monetary control necessitates deliberate policy actions that override pure market outcomes to achieve specific macroeconomic objectives.

Explanation

The socialist type of government is noted for the substantial gap between its theoretical objectives and its practical execution. Theoretically, socialism seeks to establish a classless society with collective ownership of the means of production, aiming for social equality and the eventual elimination of state coercion. In practice, however, many socialist regimes have manifested as centralized, single-party states with comprehensive control over all aspects of public and private life. Instead of the withering away of the state predicted in theory, the state often becomes an omnipresent and powerful entity, leading to a disparity between the promised empowerment of the proletariat and the actual concentration of power within a bureaucratic elite.

Explanation

The Comptroller and Auditor General (CAG) of India is known as the friend, philosopher, and guide of the Public Accounts Committee (PAC). The CAG is responsible for auditing the accounts of the Union and the States and submitting these audit reports to the President or the Governor, who then places them before the Parliament or the State Legislature. The PAC is the parliamentary committee tasked with examining these reports to ensure that public money is spent according to the law and for the intended purposes. During this examination, the CAG assists the committee by attending its meetings, interpreting complex technical data within the reports, and highlighting significant irregularities or instances of financial mismanagement. This specialized support enables the committee members to effectively scrutinize government expenditure and maintain financial accountability.

Explanation

Liberty in a civilized society is not an absolute right to act without any restraint, as such a condition would lead to a state of anarchy where the freedoms of the weak are suppressed by the strong. To ensure that all citizens can enjoy their freedoms equally and safely, liberty is regulated by law. Legislation provides the formal framework for imposing reasonable restrictions on individual actions to safeguard public order, national security, morality, and the fundamental rights of others. This concept is rooted in the principle that any curtailment of individual freedom must be authorized by the legislature through a valid legal process, ensuring that the state does not act arbitrarily. Therefore, law acts as the boundary that defines the extent of personal freedom while protecting the collective interests of the community.

Explanation

Womesh Chandra Bannerjee was the first president of the Indian National Congress during its inaugural session held in December 1885. A prominent barrister from Calcutta, he presided over the meeting at Gokuldas Tejpal Sanskrit College in Bombay, which was attended by 72 delegates representing various regions of India. The session was organized with the initiative of retired British official Allan Octavian Hume to provide a platform for educated Indians to engage in political dialogue with the British administration. Bannerjee's leadership during this first gathering established the foundational structure of the Congress as a national political organization.

Explanation

The Samiti was the general assembly of the entire tribe (vis) during the Rig Vedic period. It functioned as a folk assembly where members of the tribe gathered to deliberate on tribal business and policy. One of the most significant political responsibilities of the Samiti was the election and re-election of the Rajan, or the tribal chief. Ancient texts like the Rig Veda and Atharva Veda suggest that the king’s power was dependent on the support and approval of the Samiti, and it acted as a vital check on the chief's authority, ensuring that the leadership maintained the confidence of the tribal community.

Explanation

During the Age of the Buddha, approximately the 6th century BCE, the Kshatriyas maintained a highly distinct and powerful identity as the ruling and warrior class. This period marked the rise of the sixteen Mahajanapadas, where Kshatriya lineages like the Sakyas and the Lichchhavis exercised political sovereignty. Buddhist and Jaina canonical texts, which originated during this time, consistently place the Kshatriyas at the top of the social hierarchy, often listing them before the Brahmins. This reflects a period of intense social dynamism where the Kshatriyas were the primary patrons of heterodox religious movements and asserted their status through both political governance and intellectual leadership, distinguishing themselves clearly within the evolving Varna system.

Explanation

The Dandi March, also known as the Salt Satyagraha, was the inaugural event of the Civil Disobedience Movement. Mahatma Gandhi began the march from Sabarmati Ashram on March 12, 1930, reaching the coastal village of Dandi on April 6, 1930. By picking up a handful of salt, Gandhi symbolically broke the British salt laws, which had imposed a heavy tax and a government monopoly on a basic necessity. This act served as a signal for people across India to refuse cooperation with the British government and to peacefully violate colonial laws, marking a significant escalation in the struggle for Purna Swaraj or complete independence.

Explanation

Article 226 of the Constitution of India empowers High Courts to issue directions, orders, or writs for the enforcement of Fundamental Rights and for any other purpose. These writs include Habeas Corpus, Mandamus, Prohibition, Quo Warranto, and Certiorari. This jurisdiction allows High Courts to exercise judicial review over the actions of the government and subordinate authorities within their respective territorial limits. While the Supreme Court also has similar powers under Article 32, the High Courts possess a broader writ jurisdiction as they can issue them for both fundamental rights and ordinary legal rights.

Explanation

The population growth rate refers to the change in the number of people living in a specific area over a particular period. The most fundamental component of this change is the natural growth rate, which is calculated as the difference between the birth rate and the death rate. The birth rate represents the number of live births per thousand persons in a year, and the death rate represents the number of deaths per thousand persons in a year. Mathematically, the natural increase in population is expressed as R = b - d, where R is the natural growth rate, b is the crude birth rate, and d is the crude death rate. This indicator provides the net result of fertility and mortality within a population, showing whether the population is increasing, decreasing, or remaining stable through natural replacement.

Explanation

Relative humidity is defined as the ratio of the actual amount of water vapor present in the air to the maximum amount of water vapor that the air could hold at the same temperature and pressure. The mathematical expression for relative humidity is RH = (e / eₛ) × 100, where e represents the actual vapor pressure and eₛ represents the saturation vapor pressure. Since it measures the moisture content relative to the air's total capacity, the resulting fraction is multiplied by 100 to provide a standardized value ranging from 0 to 100 percent. A value of 100 percent indicates that the air is completely saturated and can no longer hold additional water vapor at that specific temperature.

Explanation

Metamorphism is the process by which pre-existing rocks undergo physical and mineralogical transformations in the solid state due to changes in temperature, pressure, and the presence of chemically active fluids. Textural changes occur through recrystallization, where mineral grains grow larger or change shape, and through the development of foliation or mineral alignment under directed stress. Structural changes involve the mechanical deformation of the rock mass, leading to the formation of new features like slaty cleavage, schistosity, and gneissic banding. These processes effectively modify the spatial arrangement of minerals and the overall physical framework of the rock from its original parent state.

Explanation

The Mediterranean region is globally renowned for viticulture, which is the specialized cultivation of grapes for winemaking. The distinctive Mediterranean climate, characterized by warm, dry summers and mild, rainy winters, provides the ideal environment for vineyards to flourish. This geographic zone includes southern France, Italy, Spain, and Greece, which together produce a vast majority of the world's high-quality wines. The region is particularly famous for its traditional winemaking techniques and the production of specific varieties like champagne, which originates from the chalky soils and specific climatic conditions found within these specialized agricultural belts. Mediterranean agriculture as a whole is heavily oriented toward commercial fruit and vine cultivation, making it the primary hub for the global wine industry.

Explanation

Pachytene is the third stage of Prophase I in meiosis, characterized by the completion of synapsis and the beginning of crossing-over. During this stage, the bivalent chromosomes become clearly visible as tetrads consisting of four chromatids. Crossing-over involves the physical exchange of genetic material between non-sister chromatids of homologous chromosomes. This process occurs at specific points called recombination nodules, where the enzyme complex known as recombinase facilitates the breaking and rejoining of DNA strands. This genetic recombination is a key mechanism for increasing genetic variation in sexually reproducing organisms.

Explanation

Nerium is a xerophytic plant characterized by the presence of a multiple epidermis, also referred to as a multiseriate epidermis. While the epidermis in most plants is a single layer of cells, in certain species like Nerium and Ficus, the cells of the protoderm undergo periclinal divisions to form several layers. This multilayered epidermis is a specialized adaptation to arid environments, functioning primarily to reduce water loss through transpiration. The thick layers provide an additional barrier against desiccation and protect the underlying photosynthetic ground tissue from intense solar radiation. In the leaves of Nerium, this multiple epidermis is typically present on both the dorsal and ventral surfaces, often working in conjunction with other xerophytic features like a thick cuticle and sunken stomata to ensure water conservation.

Explanation

Leukaemia is a type of cancer that originates in the blood-forming tissues of the body, primarily the bone marrow and the lymphatic system. It is characterized by the rapid and uncontrolled production of abnormal white blood cells, or leukocytes. These malignant cells are typically immature and do not function properly to protect the body against infection. As the number of these abnormal cells increases, they crowd out healthy red blood cells, platelets, and normal white blood cells in the bone marrow. This interference leads to the various symptoms associated with the disease, such as anemia, frequent infections, and easy bruising or bleeding. The term is derived from the Greek words leukos, meaning white, and haima, meaning blood, reflecting the presence of a large number of white blood cells in the bloodstream of affected individuals.

Explanation

In the majority of plants, photosynthesis follows the C₃ pathway, also known as the Calvin cycle. During the carbon fixation stage of this cycle, a molecule of carbon dioxide (CO₂) reacts with a five-carbon acceptor molecule called ribulose-1,5-bisphosphate (RuBP). This reaction is catalyzed by the enzyme RuBisCO and initially forms an unstable six-carbon intermediate. This intermediate immediately splits into two molecules of 3-phosphoglyceric acid (3-PGA). Since 3-phosphoglyceric acid is the first chemically stable compound formed after the fixation of atmospheric carbon dioxide, it is recognized as the first stable product of the photosynthetic process. While this organic acid is later reduced to form sugars, it represents the primary stable point in the biosynthetic phase.

Explanation

The pH scale is a logarithmic scale used to specify the acidity or basicity of an aqueous solution, defined as pH = -₁₀[H^+]. At a standard temperature of 25°C, the product of the molar concentrations of hydrogen ions (H^+) and hydroxide ions (OH^-) in water is always 10⁻¹⁴. Because of this relationship, the scale typically ranges from 0 to 14. A pH of 7 is considered neutral, representing pure water where the concentrations of H^+ and OH^- are equal. Solutions with a pH value less than 7 are acidic, containing a higher concentration of hydrogen ions, while solutions with a pH value greater than 7 are basic or alkaline.

Explanation

Milpa is a traditional slash-and-burn agricultural system primarily practiced in Mexico and Central America. The term originates from the Nahuatl word milpan, which translates to field or maize field. In this practice, farmers clear a plot of land by cutting down vegetation and burning the remains to create a nutrient-rich layer of ash that fertilizes the soil. This method typically involves the polycultural cultivation of maize, beans, and squash, which are often called the three sisters. These crops work together to maintain soil fertility and provide a balanced diet, forming the foundation of agricultural life in the Mesoamerican region for millennia.

Explanation

Real gases approach ideal behavior at low pressure and high temperature because these conditions satisfy the fundamental assumptions of the kinetic molecular theory. An ideal gas assumes that the volume of the gas molecules is negligible compared to the total volume of the container and that there are no intermolecular forces between the particles. At low pressure, the gas occupies a very large volume, making the actual space taken up by the molecules themselves insignificant. At high temperature, the molecules possess high kinetic energy, which allows them to move rapidly and overcome any attractive or repulsive intermolecular forces. These effects can be seen in the van der Waals equation, (P + (an²)/(V²))(V - nb) = nRT. When the pressure is low, the volume V is large, causing the pressure correction term (an²)/(V²) and the volume correction term nb to become negligible, thereby reducing the equation to the ideal gas law PV = nRT.

Explanation

According to the special theory of relativity, the relativistic mass m of a particle moving with a velocity v relative to an observer is determined by the relation m = (m₀)/(√(1 - v²){c²)}, where m₀ represents the rest mass of the particle and c is the speed of light. In this mathematical model, as the velocity v increases, the ratio (v²)/(c²) approaches unity, making the denominator √(1 - (v²)/(c²)) smaller. Consequently, the observed mass m increases compared to the rest mass. As the velocity of the particle approaches the speed of light, the denominator approaches zero, causing the relativistic mass to increase towards infinity, which implies that an infinite amount of energy would be required to accelerate a massive particle to the speed of light.

Explanation

The motion of the wheels of a bullock-cart on a road involves two simultaneous types of motion. As the cart moves forward, the wheels turn around their central axis, which constitutes rotatory motion. Simultaneously, the entire wheel as a whole moves along the surface of the road from one point to another, which constitutes translatory motion. This combination of translation and rotation allows the vehicle to progress along a path while the parts are in circular motion relative to their centers.

Explanation

An endoscope utilizes optical fibres to transmit light into the body and carry reflected images back to the observer. These fibres operate on the principle of total internal reflection, which allows light to travel through the long, flexible tube with minimal loss of intensity, even when the tube is bent or twisted. In a medical endoscope, one bundle of optical fibres carries light from an external source to illuminate the stomach lining, while another bundle captures the visual information and transmits it back to a monitor or eyepiece. This technology enables the detection of ulcers and other internal conditions through a non-surgical, minimally invasive procedure.

Explanation

IBM-DOS, also known as PC-DOS, is a single-user operating system developed by IBM for its line of personal computers. It was designed to allow one person at a time to interact with the computer system, managing hardware resources and executing application software for that individual session. The system's architecture follows a single-tasking model, where the operating system handles a single command or program execution at any given moment for one user. It lacks the complex scheduling, memory protection, and resource-sharing features necessary to support multiple users simultaneously or to manage concurrent user environments.

Explanation

Parallel processing system is a key feature of fifth-generation computing, focusing on performing multiple calculations simultaneously to enhance speed and performance. Technologies like transistors and integrated circuits belong to much earlier stages of computer development.

Explanation

Rusting is an electrochemical process involving the oxidation of iron in the presence of oxygen and moisture. The rate of this corrosion is significantly accelerated by the presence of electrolytes. Sea water contains high concentrations of dissolved salts, primarily sodium chloride (NaCl), which dissociate into ions. These ions increase the electrical conductivity of the water, facilitating the movement of electrons and ions between the anodic and cathodic areas on the metal surface. This enhanced conductivity allows the electrochemical reactions that form rust to proceed much more rapidly than they would in water with fewer dissolved minerals.

Explanation

Pleiotropy is a genetic phenomenon where a single gene influences two or more seemingly unrelated phenotypic traits. This occurs because the gene product, typically a protein or enzyme, plays a role in various biochemical pathways or is expressed in multiple different tissues throughout the organism. A classic example is the genetic disorder Phenylketonuria (PKU), where a mutation in a single gene results in multiple clinical manifestations, including mental retardation, reduced hair growth, and skin pigmentation issues. Similarly, in sickle-cell anemia, a single gene mutation affects hemoglobin structure, red blood cell shape, and confers resistance to malaria.

Explanation

Aerated water, also known as carbonated water or soda water, is created by dissolving carbon dioxide gas in water under high pressure. This process follows Henry's Law, which states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. When the gas is injected into the water at high pressure, it remains in solution until the pressure is released by opening the container. At that point, the carbon dioxide escapes in the form of bubbles, producing the characteristic fizz or effervescence. The interaction between the dissolved gas and water also creates a small amount of carbonic acid (H₂CO₃), which provides the slightly acidic taste typical of carbonated beverages.

Explanation

Magnetite is a ferrimagnetic mineral and one of the primary ores of iron, with the chemical formula Fe₃O₄. It is classified as a mixed oxide because it contains both iron(II) and iron(III) ions, often represented as FeO · Fe₂O₃. As a member of the spinel group, it is naturally occurring and possesses the highest iron content of any iron ore, approximately 72.4 percent. It is most easily identified by its black color, metallic luster, and strong magnetic properties.

Explanation

The United Nations Office for Disaster Risk Reduction (UNISDR) recognized the Government of Odisha for its exemplary handling of Cyclone Phailin, which struck the state in October 2013. Under the leadership of the state government, Odisha successfully evacuated nearly one million people into specially constructed multi-purpose cyclone shelters, resulting in a remarkably low casualty rate despite the cyclone's extreme intensity. This feat was hailed as a global benchmark in disaster management and risk reduction. In February 2014, Margareta Wahlstrom, the UN Special Representative of the Secretary-General for Disaster Risk Reduction, presented a citation to the Odisha government, acknowledging its proactive approach and effective use of early warning systems and community-based preparedness. This was the first time an Indian state was honored by the UN for its disaster management excellence.

Explanation

The Ministry of Environment and Forests is commonly designated as the Green Ministry because it serves as the nodal agency for the planning, promotion, and coordination of environmental and forestry programs in India. Its primary mandate involves the conservation of the country's natural resources, including lakes and rivers, its biodiversity, forests, and wildlife, as well as the prevention and control of pollution. The ministry is responsible for enforcing environmental laws and providing environmental clearances for various industrial and infrastructure projects, making it the central authority for ensuring that national development remains ecologically sustainable.

Explanation

Heliophytes are sun-loving plants that are specifically adapted to thrive in habitats with high light intensity and direct solar radiation. These plants possess various physiological and morphological adaptations, such as a high rate of photosynthesis and respiration, thicker leaves with a well-developed palisade layer, and often a higher density of chloroplasts to effectively utilize abundant light. The term originates from the Greek words helios, meaning sun, and phyton, meaning plant, reflecting their ecological requirement for bright environments to achieve optimal growth and development.

Explanation

The Ama Jangala Yojana, which translates to My Forest Scheme, was launched by the State Government of Odisha to increase forest cover and promote sustainable forest management through community participation. The scheme is implemented through Vana Surakshya Samitis, which are village-level committees tasked with the protection and restoration of degraded forest lands. By involving local residents in conservation efforts, the program aims to improve the ecological health of the region while providing sustainable livelihood opportunities to forest-dependent communities through the management of forest resources.

Explanation

Malgudi Days is a renowned collection of thirty-two short stories authored by R.K. Narayan, first published in 1943. The stories are set in the fictional town of Malgudi in South India, a recurring setting in most of Narayan's literary works. Through his characteristic simple and lucid prose, R.K. Narayan portrays the everyday lives, social customs, and diverse characters of the town, capturing the essence of Indian society. His contribution to Indian literature in English is significant, as he brought the nuances of Indian life to a global audience. The collection later gained even greater cultural prominence when it was adapted into a popular television series in the 1980s.

Explanation

The Ranji Trophy is the premier domestic first-class cricket championship in India. It was inaugurated by the Board of Control for Cricket in India (BCCI) in 1934 and is named after Kumar Shri Ranjitsinhji, who was the first Indian to play international cricket. The tournament is played between teams representing various regional and state cricket associations, serving as the primary breeding ground for players looking to earn a spot on the national Indian cricket team.

Explanation

The Sexual Harassment of Women at Workplace (Prevention, Prohibition and Redressal) Act, 2013, commonly known as the POSH Act, was enacted to ensure a safe and secure environment for women at their places of work. This legislation aims to protect women from sexual harassment in both organized and unorganized sectors and establishes a formal mechanism for the redressal of grievances. The Act was developed as a legislative follow-up to the Vishaka Guidelines issued by the Supreme Court of India in 1997. It mandates that every employer with ten or more employees must constitute an Internal Complaints Committee (ICC) to handle complaints. Additionally, the Act provides for Local Complaints Committees (LCC) at the district level to address cases in smaller establishments or the unorganized sector, ensuring comprehensive legal protection for women in all professional environments.

Explanation

Galvanisation is the metallurgical process of applying a protective zinc coating to iron or steel to prevent rusting. Zinc is more reactive than iron and serves as a sacrificial anode, meaning it oxidizes preferentially when exposed to the atmosphere. This provides a dual layer of protection: a physical barrier that blocks moisture and oxygen from reaching the iron surface, and cathodic protection. In the event the coating is scratched or damaged, the surrounding zinc continues to protect the underlying iron by corroding in its place. This electrochemical property ensures that the structural integrity of the iron remains intact even under harsh environmental conditions.

Explanation

Article 370 of the Indian Constitution granted special autonomous status to the state of Jammu and Kashmir. Included in Part XXI, which covers temporary, transitional, and special provisions, this article allowed the state to have its own separate constitution and flag. It restricted the legislative powers of the Union Parliament over the state, requiring the state government's concurrence for most central laws to apply, except in specific areas such as defense, foreign affairs, and communications. This provision was intended to be temporary and served as the legal basis for the state's unique relationship with the Indian Union.

Explanation

The Central Food Technological Research Institute (CFTRI) was established on 21 October 1950 as a constituent laboratory of the Council of Scientific and Industrial Research (CSIR). It is located in Mysore, Karnataka, and operates out of the historic Cheluvamba Mansion. The institute is dedicated to research and development in the field of food science and technology, focusing on areas such as food processing, preservation, nutrition, and the development of indigenous technologies to minimize post-harvest losses and enhance food safety.

Explanation

Pharmacology is the branch of medicine and biology concerned with the study of drug action, where a drug can be defined as any man-made, natural, or endogenous molecule which exerts a biochemical or physiological effect on the cell, tissue, organ, or organism. This field involves the investigation of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. It specifically deals with the discovery, chemistry, effects, and uses of drugs, including how they are absorbed, distributed, metabolized, and excreted by the body.

Explanation

Food crops are defined as plants grown specifically for human consumption as a primary source of nutrition and sustenance. This category traditionally encompasses food grains, which include cereals like rice, wheat, maize, and millets that provide essential carbohydrates. Pulses are integral to this group as they serve as the primary source of plant-based protein in the diet. Edible oilseeds, such as groundnut, mustard, and sunflower, are also classified as food crops because they are processed into cooking oils and fats, forming a fundamental part of the human food chain. These three groups together represent the essential components of the food crop sector in agricultural statistics and economic classification.

Explanation

The First Five-Year Plan of India, implemented from 1951 to 1956, was based on the Harrod-Domar model. This economic growth model suggests that the rate of economic growth is determined by two main factors: the level of savings and the capital-output ratio. According to the formula g = s/v, where g is the growth rate, s is the savings ratio, and v is the capital-output ratio, an increase in investment leads to an accumulation of capital, which in turn drives the growth of national income. In the early years of independence, India utilized this framework to prioritize the agricultural sector, irrigation, and power projects to build a self-sufficient base and overcome the prevailing food crisis and inflationary pressures.

Explanation

PIL stands for Public Interest Litigation. It refers to a legal action initiated in a court of law for the enforcement of public interest or general social welfare where the rights of an individual or a group of people are suppressed or the public interest is adversely affected. This legal tool was developed in India during the late 1970s and early 1980s by the Supreme Court, notably through the efforts of Justice P.N. Bhagwati and Justice V.R. Krishna Iyer. It relaxes the traditional rule of locus standi, allowing any public-spirited individual or organization to approach the High Courts or the Supreme Court on behalf of those who, due to poverty or social disadvantage, are unable to seek legal remedy themselves.

Explanation

Aligarh Muslim University was founded by Sir Syed Ahmed Khan, a pioneering social reformer and educator in nineteenth-century India. In 1875, he established the Muhammadan Anglo-Oriental College in Aligarh, which aimed to provide modern scientific education to the Muslim community. This institution was later incorporated as a central university in 1920 under the Aligarh Muslim University Act. The pairing in the option is incorrect because it attributes the founding to Sir Syed Murtza Khan instead of Sir Syed Ahmed Khan.

Explanation

The relationship between average revenue (AR) and marginal revenue (MR) is determined by the price elasticity of demand. Average revenue is defined as total revenue divided by quantity, which is identical to the price (AR = (TR)/(Q) = (P · Q)/(Q) = P). When the average revenue curve is a horizontal straight line, it indicates that the price remains constant regardless of the quantity sold, a condition characteristic of a firm in a perfectly competitive market.

In this scenario, total revenue is TR = P · Q, where P is a constant. Marginal revenue is the derivative of total revenue with respect to quantity (MR = (d(TR))/(dQ)). Since P is constant, (d(P · Q))/(dQ) = P. Because both AR = P and MR = P, the marginal revenue curve must be identical to the average revenue curve. Both curves coincide as the same horizontal line at the level of the prevailing market price.

Explanation

The trickle down hypothesis posits that economic growth, characterized by an increase in per capita income and overall national wealth, will naturally lead to a reduction in poverty over time. According to this perspective, as the economy expands, the benefits of growth such as increased employment opportunities, higher wages, and greater investment flow from the higher-income sectors and individuals down to the lower-income groups. The expansion of the productive capacity of the nation creates a multiplier effect that spreads wealth across different strata of society, thereby improving the living standards of the poor. This hypothesis assumes a strong positive correlation between macroeconomic prosperity and the alleviation of poverty at the grassroots level through market mechanisms.

Explanation

John Maynard Keynes identified the volatility of investment as the primary cause of business cycles. According to his theory, the volume of investment depends on the relationship between the Marginal Efficiency of Capital (MEC) and the market rate of interest. The MEC is the highest rate of return expected from an additional unit of a capital asset. While the market rate of interest is determined by liquidity preference and the money supply and tends to be relatively stable, the MEC is highly unstable. It depends on the subjective expectations of entrepreneurs regarding future yields, which are influenced by what Keynes termed animal spirits. A sudden collapse in the MEC, driven by a shift from optimism to pessimism about future profitability, leads to a sharp decline in investment and triggers an economic downturn. Conversely, a rise in the MEC stimulates investment and leads to an expansion.
