SSC CGL Tier 1 2014 General Awareness Questions with Solutions

Explanation

The National Anthem of India, Jana Gana Mana, was originally composed in Bengali by Rabindranath Tagore and was adopted in its Hindi version by the Constituent Assembly on 24 January 1950. According to the official instructions issued by the Government of India, the playing time of the full version of the National Anthem is approximately 52 seconds. A shorter version consisting of the first and last lines of the stanza is also played on certain occasions, which takes approximately 20 seconds.

Explanation

The Tomb of Jahangir is a 17th-century mausoleum built for the Mughal Emperor Jahangir, who ruled from 1605 to 1627. It is located in Shahdara Bagh, Lahore, on the banks of the Ravi River in present-day Pakistan. The construction of the tomb was commissioned by his son and successor, Emperor Shah Jahan, and was completed in 1637. The monument is situated within a large walled garden known as a Charbagh and is renowned for its intricate use of marble stringing and floral pietra dura patterns. The structure features a single-story square building with four tall, octagonal minarets at each corner decorated with chequered oil paintings and variegated marble. This site remains one of the most significant examples of Mughal architecture in the region.

Explanation

Nur Jahan was born with the name Mehr-un-Nissa. She was the daughter of Mirza Ghiyas Beg, a Persian immigrant who rose to a high position in the Mughal court. After the death of her first husband, Sher Afghan, she married the Mughal Emperor Jahangir in 1611. It was Jahangir who bestowed upon her the titles Nur Mahal and later Nur Jahan, reflecting her beauty and the significant influence she wielded over the imperial administration.

Explanation

The theory of factor pricing is synonymous with the theory of functional distribution because it explains how the total national income is divided among the different factors of production based on the functions they perform in the productive process. These factors include land, labor, capital, and entrepreneurship, which receive rewards in the form of rent, wages, interest, and profit, respectively. Functional distribution focuses on the pricing of these factor services and how their respective shares in the total output are determined by their marginal productivity and the prevailing market forces of demand and supply. Since the analysis pertains to the distribution of income to the owners of factors according to the function of the factor itself, it is termed functional distribution.

Explanation

The Securities and Exchange Board of India (SEBI) was established on April 12, 1988, through an administrative resolution of the Government of India. It was initially formed as a non-statutory body to function under the administrative control of the Ministry of Finance, aimed at regulating the securities market and protecting the interests of investors. Although SEBI was later granted statutory status and autonomous powers on January 30, 1992, through the SEBI Act, its original inception and setup occurred in 1988.

Explanation

In a free enterprise economy, the allocation of resources is primarily guided by the price mechanism and the principle of consumer sovereignty. Consumers signal their preferences and the intensity of their demands through their spending patterns in the marketplace. These signals inform producers about which goods and services are most valued. Driven by the profit motive, entrepreneurs allocate land, labor, and capital toward the production of items that consumers are willing to purchase. Thus, the collective spending decisions of consumers act as the fundamental directing force that determines what is produced and how society's scarce resources are distributed among competing uses.

Explanation

The Rashtriya Krishi Bima Yojana (RKBY), also known as the National Agriculture Insurance Scheme (NAIS), was launched by the Government of India during the Rabi season of 1999-2000. It was introduced to provide financial support and insurance coverage to farmers in the event of crop failure caused by natural calamities, pests, or diseases. The scheme replaced the earlier Comprehensive Crop Insurance Scheme (CCIS) and aimed at stabilizing farm incomes, particularly for small and marginal farmers, by covering food crops, oilseeds, and annual commercial or horticultural crops. It was implemented through the Agriculture Insurance Company of India Limited (AIC).

Explanation

Perfect competition is a market structure defined by several conditions, one of which is that all buyers and sellers have complete and perfect knowledge regarding the price and quality of products. In this model, information is free and symmetric, preventing any single participant from gaining an advantage over others.

Explanation

Under Article 78 of the Constitution of India, the Prime Minister serves as the principal channel of communication between the President and the Council of Ministers. This constitutional provision mandates that it is the duty of the Prime Minister to communicate to the President all decisions of the Council of Ministers relating to the administration of the affairs of the Union and proposals for legislation. Furthermore, the Prime Minister must furnish such information relating to the administration of the affairs of the Union as the President may call for. The Prime Minister also acts as the link when the President requires a matter decided by an individual minister to be submitted for the consideration of the collective Council. This structural arrangement ensures that the President, as the formal head of the executive, is kept informed of all significant executive and legislative developments by the actual head of the government.

Explanation

Australia has consistently ranked as the largest producer of bauxite in the world for several decades, including the periods around 2007 and 2014. The country possesses vast, high-grade reserves that are easily accessible through open-cut mining. Major operations are concentrated in the Darling Range of Western Australia, the Weipa deposit in Queensland, and the Gove Peninsula in the Northern Territory. During this timeframe, Australia's annual bauxite production significantly exceeded that of other mining nations, driven by its integrated aluminum industry and strong export demand from global markets.

Explanation

The Himalayas and the Western Ghats are the two most significant biodiversity hotspots in India, recognized for their immense species richness and high levels of endemism. The Himalayas provide a unique range of altitudinal zones, from tropical foothills to alpine meadows, which support a vast array of flora and fauna. The Western Ghats, a mountain range along the western coast, are globally renowned for their dense tropical evergreen forests and a high concentration of species found nowhere else on Earth. These eco-zones are considered the richest because they harbor a disproportionately large number of India's plant and animal species, making them critical regions for conservation and ecological stability.

Explanation

At the time of independence in 1947, the Indian economy was structurally underdeveloped and characterized by a massive dependence on the primary sector, with nearly 75 percent of the population engaged in farming. Agriculture was largely rain-fed and relied on primitive technology, such as wooden ploughs and bullocks, leading to extremely low productivity per hectare. Most farmers worked on small, fragmented landholdings with the primary objective of producing enough food to sustain their own households rather than for commercial sale or profit. This system of farming, where the output is consumed locally by the producers and their families with little to no surplus for the market, defines subsistence agriculture. Consequently, it was the predominant form of agricultural practice across the country during the mid-20th century.

Explanation

Endemic species are those that are naturally found only in a specific geographic area, such as a particular island, mountain range, or country, and are not found anywhere else in the world. This restriction in distribution is often the result of geographic isolation or physical barriers that prevent the species from spreading to other regions. Because their habitat is limited to a single location, these species are often more vulnerable to extinction if their specific environment is disturbed. Typical examples include the lemurs of Madagascar or the unique flora and fauna found in the Galapagos Islands.

Explanation

2,4-D, which stands for 2,4-Dichlorophenoxyacetic acid, is a synthetic plant hormone belonging to the auxin class. It is primarily used as a selective weedicide to control broadleaf weeds in agricultural fields, lawns, and pastures. By mimicking the action of natural plant growth regulators, 2,4-D causes rapid, unsustainable growth in dicotyledonous plants, leading to their eventual death. Because most grasses and cereal crops are monocotyledonous and relatively resistant to its effects at standard application rates, it is an effective tool for eliminating competing weeds without damaging the primary crop.

Explanation

The Widal test is a serological procedure used primarily for the diagnosis of enteric fever, which includes typhoid and paratyphoid fever. Developed by Georges-Fernand Widal in 1896, the test measures the presence of specific agglutinating antibodies against the O (somatic) and H (flagellar) antigens of Salmonella typhi and Salmonella paratyphi in a patient serum. When these antibodies encounter the corresponding bacterial antigens, they cause the bacteria to clump together, a process known as agglutination. This diagnostic tool is particularly valuable in clinical medicine for identifying infections caused by these specific pathogens, especially in areas where more advanced molecular testing may not be readily available.

Explanation

The Charter Act of 1813 abolished the East India Company's monopoly on trade with India, effectively opening Indian markets to all British private merchants. This legislative change was prompted by the demand of British commercial interests and the economic pressures caused by Napoleon's Continental System, which had closed European ports to British goods. By ending the Company's commercial privileges, the Act allowed for the entry of private capital and missionaries into India. Although the Company lost its exclusive rights to Indian trade, it was permitted to retain its monopoly over the tea trade and the trade with China for another twenty years.

Explanation

The Declaration of the Rights of Man and of the Citizen was a fundamental document of the French Revolution, adopted by the National Constituent Assembly in August 1789. It was deeply influenced by Enlightenment philosophy, particularly the concept of natural rights and the political theories of Jean-Jacques Rousseau. The declaration asserted that all men are born and remain free and equal in rights, emphasizing principles such as liberty, property, security, and resistance to oppression. By establishing that sovereignty resides in the nation rather than the monarch, it served as a foundational text for modern democracy and signaled the end of the feudal system and absolute monarchy in France.

Explanation

The Ottawa Agreement was the result of the Imperial Economic Conference held in Ottawa, Canada, in 1932. It established the system of Imperial Preference, under which Great Britain and its autonomous Dominions and colonies agreed to grant reciprocal tariff concessions to one another. This policy created a protected trading bloc by imposing lower customs duties on goods traded within the British Empire while maintaining higher tariffs on imports from non-empire countries. The primary objective was to bolster the imperial economy and protect British manufacturing interests from foreign competition during the global economic downturn of the Great Depression. In India, the agreement was met with significant political resistance as it was perceived as a tool to exploit the Indian market for the benefit of British industries.

Explanation

Venus is the hottest planet in the solar system due to its incredibly dense atmosphere, which is composed of approximately 96.5% carbon dioxide. This high concentration of greenhouse gases triggers a runaway greenhouse effect, trapping solar radiation and preventing heat from escaping back into space. As a result, the surface temperature of Venus remains relatively uniform and extremely high, averaging about 462°C (864°F). This temperature is hot enough to melt lead and surpasses the maximum surface temperature of Mercury, even though Mercury is much closer to the Sun.

Explanation

Under normal atmospheric conditions in the troposphere, the temperature decreases with increasing altitude at an average rate known as the normal lapse rate. A temperature inversion occurs when this standard relationship is reversed, resulting in a layer of the atmosphere where the temperature actually increases with height. This phenomenon typically happens when a layer of warmer air moves over a cooler layer or when the ground cools rapidly at night through terrestrial radiation, chilling the air immediately above it while the air at higher altitudes remains relatively warmer.

Explanation

In a conductor, the valence band and the conduction band overlap each other, meaning there is no forbidden energy gap (E_g = 0) between them. This physical overlap allows electrons to transition from the valence band to the conduction band with negligible energy input. Consequently, a large number of free electrons are always available for conduction, even at very low temperatures, which results in the high electrical conductivity characteristic of metallic substances.

Explanation

An assembler is a specialized software utility that translates assembly language into machine code. Assembly language is a low-level programming language that uses symbolic mnemonics, such as ADD, SUB, or MOV, to represent the fundamental operations of a computer processor. Since the central processing unit can only execute instructions in binary format, the assembler performs a one-to-one mapping process where it converts these human-readable mnemonics and symbolic addresses into the specific bit patterns and opcodes that the hardware understands.

Explanation

In digital computing and memory addressing, storage capacities are calculated based on the binary system (base 2) because electronic circuits use two states, represented as 0 and 1. The prefix kilo in the context of computer memory signifies 2¹⁰ units. By calculating this value, 2¹⁰ equals 1024. Therefore, one kilobyte consists of 1024 bytes. This binary definition ensures that memory sizes align perfectly with the architecture of address buses and logic gates, which operate in powers of two rather than the decimal base 10 system used in standard metric measurements.

Explanation

Lithium is an alkali metal belonging to Group 1 of the periodic table. It has a valence electronic configuration of 2s¹. Because it has only one electron in its outermost shell and a relatively large atomic radius compared to non-metals in the same period, the effective nuclear charge holding that valence electron is weak. This results in a low first ionization energy, making it very easy for Lithium to lose its single valence electron to achieve a stable, noble gas electron configuration (1s²). In contrast to non-metals which have high electronegativity or transition metals with higher nuclear charges, alkali metals like Lithium exhibit the highest electropositivity and the greatest tendency to undergo oxidation by losing electrons.

Explanation

Zinc phosphide (Zn₃P₂) is a highly effective inorganic rodenticide used globally for controlling rat populations. When a rodent ingests the poison, the zinc phosphide reacts with the hydrochloric acid (HCl) in the animal's stomach to release phosphine gas (PH₃), as shown in the reaction: Zn₃P₂ + 6HCl → 3ZnCl₂ + 2PH₃. This phosphine gas is extremely toxic; it enters the bloodstream and causes rapid damage to the central nervous system, liver, lungs, and heart, leading to the death of the rodent. The strong, pungent odor associated with the release of the gas also acts as a bait attractant for rats while making it less likely to be accidentally consumed by humans or other domestic animals.

Explanation

Antacid tablets are formulated using mild bases to neutralize excess hydrochloric acid in the gastric juice, alleviating symptoms of heartburn and indigestion. Magnesium hydroxide, Mg(OH)₂, and aluminium hydroxide, Al(OH)₃, are the standard hydroxide components employed for this purpose. These substances are effective as they are non-systemic antacids with low solubility, ensuring they react locally in the stomach to produce water and neutral salts. The chemical reactions involved are Mg(OH)₂ + 2HCl → MgCl₂ + 2H₂O and Al(OH)₃ + 3HCl → AlCl₃ + 3H₂O. These specific hydroxides are chosen for their safety and ability to provide a buffered neutralization without causing the tissue damage associated with strong, caustic hydroxides like sodium hydroxide.

Explanation

Nitrogen is unique among the essential mineral nutrients because plants can absorb it in two different ionic forms: the cation ammonium (NH₄^+) and the anion nitrate (NO₃^-). While nitrate is the most common form of nitrogen available in well-aerated soils due to the process of nitrification, many plants also readily take up ammonium, especially in acidic or anaerobic soil conditions. The ability to utilize both forms allows plants to adapt to various soil environments and helps in maintaining the internal charge balance and pH of the rhizosphere during nutrient uptake.

Explanation

During periods of continuous strenuous physical exercise, the demand for energy in the muscles exceeds the amount of oxygen available for aerobic respiration. To compensate for this oxygen debt, muscle cells switch to anaerobic respiration. In this biochemical pathway, glucose is converted into lactic acid (C₃H₆O₃) to generate ATP quickly without the need for oxygen. The accumulation of lactic acid in the muscle tissues increases the acidity of the cellular environment, which interferes with metabolic processes and muscle contraction, ultimately resulting in muscular fatigue and cramping.

Explanation

Thalassemia is a group of inherited blood disorders characterized by a reduced or absent production of one or more of the globin chains that form hemoglobin. This condition is frequently caused by frame shift mutations, which involve the insertion or deletion of a number of nucleotides in the DNA sequence that is not a multiple of three. Since the genetic code is read in triplets called codons, such an alteration shifts the reading frame for all subsequent codons during the translation process. This typically leads to the synthesis of a completely different amino acid sequence or the appearance of a premature stop codon, resulting in a non-functional or severely truncated globin protein. The resulting quantitative deficiency of hemoglobin subunits distinguishes thalassemia from qualitative disorders like sickle cell anemia.

Explanation

Eutrophication is the enrichment of water bodies with nutrients like nitrates and phosphates, which triggers the excessive growth of algae and aquatic plants known as algal blooms. This rapid increase in biomass directly enhances the production of organic matter in the ecosystem. When this massive amount of organic matter eventually dies, it is broken down by aerobic bacteria through decomposition. This process consumes significant amounts of dissolved oxygen, thereby increasing the Biological Oxygen Demand (BOD) of the water body. Consequently, eutrophication leads to both higher organic productivity and a subsequent rise in the oxygen required for its degradation.

Explanation

The moment of inertia I of a rigid body is defined by the formula I = Σ mᵢ rᵢ² for a system of particles or I = ∫ r² dm for a continuous mass distribution. In these expressions, m represents the mass and r represents the perpendicular distance of the mass elements from the axis of rotation. Consequently, the moment of inertia is an intrinsic property determined by the total mass, the shape and size of the body, the distribution of mass relative to the axis, and the position and orientation of the axis of rotation itself. Angular velocity is a kinematic variable that describes the state of motion of the body. Although angular velocity is used to calculate rotational kinetic energy K = ½ I ω² and angular momentum L = I ω, the value of I remains constant for a rigid body regardless of how fast it rotates or whether it is at rest.

Explanation

The mechanical advantage in opening a door is governed by the principle of torque, which is the turning effect of a force. Torque τ is expressed by the formula τ = r F sin θ, where r is the perpendicular distance from the axis of rotation (the hinges) to the point where the force is applied, F is the magnitude of the force, and θ is the angle between the force and the lever arm. To open a door easily, one must minimize the required force F. According to the relation F = τ / (r sin θ), the force required is inversely proportional to the distance r. Therefore, to achieve the maximum ease of operation, the handle must be fixed at the maximum possible distance from the hinges, which is at the extreme edge of the door opposite the hinges. None of the specific placements described in the other options correctly identify this optimal location at the farthest edge.

Explanation

Nucleons, which include protons and neutrons, are composite subatomic particles made up of elementary particles called quarks. According to the Standard Model of particle physics, baryons like nucleons consist of three quarks bound together by the strong interaction. Specifically, a proton is composed of two up quarks and one down quark (uud), giving it a net positive charge of +1e. A neutron is composed of one up quark and two down quarks (udd), resulting in a net neutral charge of 0. These quarks are held in place by the exchange of gluons, which act as the force carriers for the strong nuclear force within the nucleus.

Explanation

The Euro was established by the 1992 Maastricht Treaty as a core component of the European Economic and Monetary Union. It was officially launched on January 1, 1999, initially for electronic payments and accounting purposes, before physical notes and coins entered circulation on January 1, 2002. As the common currency for the Eurozone, it was designed to enhance economic integration, eliminate exchange rate risks, and lower transaction costs among participating member states of the European Union.

Explanation

National Science Day is celebrated in India on 28th February every year to mark the discovery of the Raman Effect by the Indian physicist Sir Chandrasekhara Venkata Raman. On this day in 1928, Sir C.V. Raman discovered a phenomenon in the scattering of light which later came to be known as the Raman Effect. For this path-breaking discovery, he was awarded the Nobel Prize in Physics in 1930, making him the first Indian and first Asian to receive a Nobel Prize in any branch of science. The Government of India designated 28th February as National Science Day in 1986 to encourage scientific temper and recognize the contributions of scientists to the nation's development.

Explanation

The Red Data Book is a comprehensive record maintained by the International Union for Conservation of Nature (IUCN) for documenting the conservation status of biological species. It identifies and lists species of plants, animals, and fungi that are rare or facing a significant risk of extinction. The book categorizes these organisms into different levels of threat, such as Critically Endangered, Endangered, and Vulnerable, based on specific criteria like population decline and geographical range. This data serves as a critical global reference for researchers and policymakers to prioritize conservation efforts and implement measures to prevent the loss of biodiversity.

Explanation

The Jnanpith Award is the highest and most prestigious literary honour in India. Established in 1961 by the Bharatiya Jnanpith, a research and cultural institute, it is presented annually to an Indian author for their outstanding contribution to literature. The award is conferred upon writers who produce works in any of the 22 languages listed in the Eighth Schedule of the Indian Constitution or in English. It carries a cash prize, a citation plaque, and a bronze statue of Vagdevi (Saraswati). While it was initially given for specific literary works, since 1982 the Jnanpith Award has been awarded for a writer's overall lifetime contribution to Indian literature. The first recipient of this honour was the Malayalam poet G. Sankara Kurup in 1965.

Explanation

Marie Curie, in collaboration with her husband Pierre Curie, discovered the radioactive element radium in 1898. They identified it while investigating the properties of pitchblende, an ore of uranium, which exhibited levels of radioactivity that suggested the existence of previously unknown elements. Through a rigorous chemical process of fractional crystallization, they isolated radium, a discovery that fundamentally changed the understanding of atomic physics and chemistry. Her pioneering work on radioactive substances led to her being awarded the Nobel Prize in Chemistry in 1911.

Explanation

The Golden Globe Awards are prestigious annual accolades bestowed by the Hollywood Foreign Press Association (HFPA) to recognize outstanding achievements in the entertainment industry, specifically focusing on film and television. Since their inception in 1944, they have become one of the most significant awards in the cinematic world, honoring excellence in various categories such as direction, acting, and production for both domestic and international motion pictures. They are widely regarded as a major precursor to the Academy Awards within the annual film awards season.

Explanation

Ustad Bismillah Khan was a legendary musician who is credited with popularizing the Shehnai and elevating it from a traditional folk instrument used in weddings and temples to the status of a premier classical concert instrument. Born in Bihar and later based in Varanasi, he became a symbol of Indias syncretic culture through his mastery of the instrument. His immense contribution to Indian classical music earned him the Bharat Ratna, Indias highest civilian award, in 2001. He also holds the historic distinction of performing the Shehnai from the ramparts of the Red Fort on the occasion of Indias first Independence Day on August 15, 1947.

Explanation

Oxygen (O₂) is not a greenhouse gas because it is a homonuclear diatomic molecule. According to the selection rules for infrared (IR) spectroscopy, a molecular vibration is IR-active only if it results in a change in the molecule's dipole moment, expressed as (dμ)/(dq) ≠ 0. Since oxygen consists of two identical atoms, it has no permanent dipole moment, and its symmetry is maintained during its single vibrational mode (the stretching of the O=O bond). Because there is no change in the dipole moment during vibration, oxygen cannot absorb or emit the thermal infrared radiation emitted by the Earth's surface. This allows infrared energy to pass through the molecule without being trapped, preventing it from contributing to the greenhouse effect.

Explanation

Sulfur dioxide (SO₂) enters plant leaves primarily through the stomata and reacts with the water in the mesophyll cells to form toxic sulfite (SO₃²⁻) and bisulfite (HSO₃⁻) ions. These ions disrupt the photosynthetic process and damage cellular membranes. Acute exposure leads to the rapid death of leaf tissue, known as necrosis. Since the leaf veins and the cells immediately surrounding them are more resistant to these chemical changes or have higher buffering capacities, the damage is concentrated in the tissue between the veins. This results in the characteristic appearance of interveinal necrotic spots, which are often bleached, tan, or reddish-brown in color.

Explanation

Nuclear fallout is the residual radioactive material propelled into the atmosphere following a nuclear explosion, consisting of weapon debris, fission products, and activated environmental materials. It contains various radioisotopes that emit different types of ionizing radiation during their decay processes. Heavy transuranic elements like plutonium-239 and unspent uranium-235, which are present in the fallout debris, decay by emitting alpha particles. Simultaneously, the vast majority of fission products, such as strontium-90, cesium-137, and iodine-131, are neutron-rich isotopes that achieve stability through beta decay, releasing B-particles. Because the atmospheric debris from a detonation includes both these heavy actinides and various fission fragments, the resulting fallout contains both alpha and beta emitters.

Explanation

Chilika Lake, located in Odisha, is a brackish water lagoon and the largest coastal salt-water lake in India. In contrast, Jaisamand, the Ganga river, and the Yamuna river are all considered freshwater resources.

Explanation

Rajnath Singh was appointed as the Minister of Home Affairs in the Union Cabinet of India following the victory of the Bharatiya Janata Party-led National Democratic Alliance in the 2014 general elections. He assumed office on May 26, 2014, in the first cabinet headed by Prime Minister Narendra Modi. In this capacity, he was responsible for the country's internal security, management of paramilitary forces, and maintenance of center-state relations. His tenure as Home Minister during this period involved overseeing key policy decisions regarding border security and national law enforcement.

Explanation

Manmohan Singh served as the Prime Minister of India from 2004 to 2014. In the chronological sequence of individuals who have held the office, he is the 14th person to serve as Prime Minister, a count that includes Gulzarilal Nanda who served in an acting capacity. Appointed in 2004, he led the United Progressive Alliance (UPA) government for two full terms across the 14th and 15th Lok Sabha. He was the first Prime Minister since Jawaharlal Nehru to be re-elected after a full five-year term and was the first person from the Sikh community to hold the position. During his tenure, he oversaw significant economic growth and the implementation of key policies such as the Indo-US civil nuclear agreement.

Explanation

Kolkata is widely recognized as the cultural capital of India due to its historical role as the birthplace of modern Indian literary, artistic, and scholastic thought. During the 19th and early 20th centuries, the city was the heart of the Bengal Renaissance, a period of great social reform and intellectual awakening that produced legendary figures such as Rabindranath Tagore, Ishwar Chandra Vidyasagar, and Swami Vivekananda. This legacy continues through the city's deep-rooted passion for cinema, theatre, music, and literature, alongside its vibrant celebration of festivals and its status as a premier center for the arts and humanities in the country.

Explanation

A unit price elastic demand curve, where the price elasticity of demand is equal to one at every point, is represented geometrically as a rectangular hyperbola. The fundamental property of this curve is that the total expenditure, calculated as the product of price (P) and quantity demanded (Q), remains constant (P × Q = k). For this mathematical relationship to hold, neither P nor Q can ever reach zero. As the price increases, the quantity decreases proportionally to keep the product constant, and as the price decreases toward zero, the quantity increases toward infinity. Because the curve is asymptotic to both the vertical price axis and the horizontal quantity axis, it extends infinitely in both directions without ever making contact with or intersecting either axis.

Explanation

India's policy of non-alignment, pioneered by Jawaharlal Nehru during the Cold War, represents a strategic choice to maintain independence in foreign affairs by refusing to join any major military alliances or power blocs. Specifically, it meant staying clear of the rivalries between the Western bloc led by the United States and the Eastern bloc led by the Soviet Union. This neutrality towards power blocs allowed India to preserve its national sovereignty and evaluate international issues based on their own merits and India's own national interests rather than being bound by the collective security obligations or ideological constraints of a superpower-led alliance.

Explanation

The price elasticity of supply eₛ measures the responsiveness of quantity supplied to changes in price and is defined by the formula eₛ = (dq)/(dp) · (p)/(q). A linear supply curve can be expressed by the equation q = c + β p, where β represents the slope dq/dp and c is the intercept on the quantity axis. If the supply curve passes through the origin, the intercept c is zero, simplifying the equation to q = β p. Substituting the derivative β and the expression for q into the elasticity formula yields eₛ = β · (p)/(β p) = 1. Consequently, any straight-line supply curve originating from the (0,0) coordinate possesses a constant price elasticity of unity at every point along the curve, as the ratio of price to quantity always matches the inverse of the slope.
