SSC CGL Tier 1 2014 General Awareness Questions with Solutions

Explanation

Mahatma Gandhi firmly believed that politics and religion are inseparable, asserting that politics must be rooted in morality and ethical values. For Gandhi, religion did not mean sectarianism or narrow dogma, but rather the underlying moral order and the pursuit of Truth (Satyagraha). He famously stated that those who say religion has nothing to do with politics do not know what religion means, as he viewed political activity as a means for spiritual salvation and the service of humanity. He argued that politics bereft of religion is a death-trap because it kills the soul, emphasizing that every political action should be guided by a sense of religious duty and conscience.

Explanation

Major Rock Edict XIII is the primary historical source that records Ashoka's conquest of Kalinga during his eighth regnal year. In this inscription, Ashoka explicitly details the immense human toll of the conflict, citing that hundreds of thousands of individuals were killed, captured, or displaced. The edict captures his deep personal sorrow and repentance for the violence, leading to his monumental decision to abandon military expansion. Instead, he advocates for Dhamma-vijaya, or victory through righteousness, and emphasizes the spread of Dhamma throughout his empire and beyond to various Hellenistic kingdoms. This edict serves as the definitive record of his transition from a warrior king to a proponent of peace and non-violence.

Explanation

Akbar constructed the Ibadat Khana, or the House of Worship, at Fatehpur Sikri in 1575 for the purpose of holding theological discussions. Initially, these debates were confined to Muslim scholars of various sects. However, driven by a desire for deeper spiritual understanding, Akbar opened the doors of the Ibadat Khana in 1578 to representatives of all major religions, including Hindus, Christians, Jains, Zoroastrians, and Sikhs. These sessions allowed the Emperor to explore the diverse philosophies of different faiths, eventually leading to his formulation of the syncretic belief system known as Din-i-Ilahi, which emphasized universal peace and religious tolerance.

Explanation

Guru Nanak Dev Ji, the founder of Sikhism, chose his disciple Bhai Lehna to be his successor before his death in 1539. To signify that the successor was an extension of his own self and spirit, Nanak renamed him Guru Angad, which means part of one's own body. Guru Angad Dev Ji became the second of the ten Sikh Gurus and is noted for formalizing the Gurmukhi script and collecting the hymns of Guru Nanak.

Explanation

The Rig Vedic Aryans initially settled in the geographical region known as Sapta Sindhu, which translates to the Land of the Seven Rivers. This area corresponds to the northwestern part of the Indian subcontinent, encompassing the Indus river and its five main tributaries—the Vitasta, Asikni, Parushni, Vipasa, and Sutudri—along with the Saraswati river. The hymns of the Rig Veda, the oldest Vedic text, provide extensive evidence of this settlement by frequently describing the topography and hydrology of this specific region, establishing it as the primary home of the early Aryan tribes during their initial phase of migration and habitation.

Explanation

Rudolf Hess, who served as the Deputy Fuhrer of the Nazi Party, made this declaration during the Nuremberg Rally in 1934. The statement was a key component of the Nazi effort to cultivate an absolute cult of personality around Adolf Hitler, effectively merging the identity of the leader with the nation itself. By asserting that loyalty to Hitler was synonymous with loyalty to Germany, Hess reinforced the "Fuhrerprinzip", or leader principle, which demanded unquestioning obedience to the Fuhrer as the ultimate authority in the Third Reich. This rhetoric was central to the totalitarian control and ideological alignment of the German state during the Nazi era.

Explanation

Ramsay Muir, a British historian and thinker, characterized the Cabinet as the steering wheel of the ship of state in his work How Britain is Governed. This metaphor illustrates the Cabinet's supreme role in policy formulation and its executive power to guide the direction of the government's administration and legislative agenda. Muir emphasized that while the Parliament represents the ship, it is the Cabinet that provides the essential navigation and control required to manage the state's affairs effectively. Through this definition, he highlighted the concentration of power within the Cabinet in the British parliamentary system, where it serves as the central coordinating body that initiates most public policy and directs the legislative process.

Explanation

Lord Morley described the Prime Minister as primus inter pares, which translates to first among equals. This political concept highlights the Prime Minister's position as the leader of the Cabinet while maintaining that they are technically of the same rank as other ministers. Morley used this phrase to emphasize the collegiate nature of the parliamentary system, where the Prime Minister is the head of the team but functions within the framework of collective responsibility and shared executive authority.

Explanation

Mixed farming is an agricultural system in which a farmer conducts both crop cultivation and the rearing of livestock on the same piece of land. This integrated approach ensures that the farm remains productive throughout the year, as livestock can provide a steady income through products like milk, meat, or wool while crops are in their growing cycle. Additionally, mixed farming promotes a sustainable nutrient cycle within the farm ecosystem, where animal waste is utilized as organic manure to improve soil fertility for better crop yields, and crop residues are used as fodder for the animals.

Explanation

Hydraulic action is a mechanical erosional process where the sheer force of moving water dislodges and removes loose material from the banks and bed of a river. As running water strikes the rock surface, it forces water and air into small cracks and crevices. The pressure of the water compresses the trapped air; when the water recedes, the sudden release of this pressure causes the air to expand explosively, which weakens the rock and causes fragments to break away over time. This process is particularly effective in high-velocity streams and during periods of high discharge.

Explanation

The Cretaceous Period represents the most recent geological timeframe among the choices, spanning from approximately 145 million years ago to 66 million years ago. It is the third and final period of the Mesozoic Era, following the earlier divisions of that era. Its conclusion is defined by the Cretaceous-Paleogene extinction event, which occurred roughly 66 million years ago and marked the transition into the modern Cenozoic Era. This placement makes it the chronologically closest period to the present day out of the provided geological time intervals.

Explanation

The cocoa plant, Theobroma cacao, is an evergreen tree that typically reaches a height of 4 to 8 meters (13 to 26 feet). In botanical classification, it is considered a small tree rather than a shrub or a large tree.

Explanation

Acetabularia is a genus of green algae that consists of a single cell and can reach sizes of up to 10 centimeters, making it significantly larger than Yeast, Acetobacter, or typical species of Amoeba. While some species of Amoeba are visible to the naked eye, they generally do not reach the macro-scale dimensions of Acetabularia.

Explanation

Jagadish Chandra Bose invented the crescograph in the early 20th century to measure the growth and movement of plants. This highly sensitive instrument was designed to magnify the motion of plant tissues by a factor of up to 10,000, enabling the observation of growth increments as small as 1/100,000 of an inch per second. By using the crescograph, Bose was able to record how plants respond to various stimuli, such as electricity, chemicals, and light, demonstrating that plant life exhibits physiological responses similar to those of animals. His work with this device laid the foundation for modern plant physiology and provided experimental evidence for the irritability of plant tissues in response to environmental changes.

Explanation

The Foramen Magnum is a large, oval-shaped opening located in the occipital bone at the base of the skull. It serves as the primary conduit through which the medulla oblongata of the brain exits the cranial cavity to become the spinal cord. This aperture also facilitates the passage of other essential structures, including the vertebral arteries, the spinal accessory nerves, and the anterior and posterior spinal arteries. The position and orientation of the foramen magnum are significant anatomical markers, as they reflect the posture and locomotion of an organism, being situated more centrally in bipedal humans compared to other mammals.

Explanation

Mir Jafar served as the Commander-in-Chief of the Nawab Siraj-ud-Daula's army during the Battle of Plassey in 1757. Prior to the engagement, he entered into a secret agreement with Robert Clive and the British East India Company, who promised to install him as the Nawab of Bengal in exchange for his assistance in overthrowing Siraj-ud-Daula. During the battle, Mir Jafar withheld his large division of troops from the field, ensuring the Nawab's defeat. This act of treachery allowed a relatively small British force to overcome the Nawab's army, effectively marking the beginning of British political supremacy in the Indian subcontinent.

Explanation

Kelps are large brown algae or seaweeds that belong to the order Laminariales and grow in cool, nutrient-rich shallow coastal waters. These marine plants are known for their ability to concentrate minerals from seawater, particularly iodine, within their tissues. Historically, kelp was the primary source used for the industrial production of iodine and soda ash. Because they can contain significantly higher concentrations of iodine than the surrounding water, they are a vital natural source of this element, which is essential for thyroid function and various industrial applications.

Explanation

Basalt is an extrusive igneous rock formed from the rapid cooling of magnesium-rich and iron-rich lava. It is the odd item in the list because it is a rock—a solid aggregate composed of several different minerals like plagioclase and pyroxene—rather than a single mineral species or a precious gemstone. While the other items are specific varieties of precious gemstones valued for their rarity and use in jewelry, basalt is a common geological formation that constitutes much of the Earth's oceanic crust.

Explanation

The time taken for sunlight to reach the Earth is determined by the relationship t = ᵈ⁄ᵥ, where d is the distance from the Sun to the Earth and v is the speed of light. The average distance between the Sun and the Earth is approximately 150 million kilometers (1.5 × 10⁸ km), and light travels at a constant speed of approximately 300,000 kilometers per second (3 × 10⁵ km/s) in a vacuum. By dividing the distance by the speed, the travel time is calculated to be approximately 500 seconds. When converted into minutes (500 ÷ 60), this equals approximately 8.33 minutes, or roughly 8 minutes and 20 seconds.

Explanation

Radar, which stands for Radio Detection and Ranging, is an electronic system that uses radio waves to identify the range, altitude, direction, or speed of objects. The system operates by emitting electromagnetic pulses from a transmitter; when these waves strike a distant object, they are reflected back to a receiver. By calculating the time delay between the pulse emission and the return of the echo, the radar determines the distance of the object, while the orientation of the antenna provides its direction. This allows for the effective detection and tracking of distant targets such as aircraft, ships, and weather formations.

Explanation

Optical fibers function through the phenomenon of total internal reflection. These fibers are constructed with a central core made of high-quality glass or plastic surrounded by a cladding layer with a lower refractive index. When light enters the fiber at a specific angle, it hits the boundary between the core and the cladding. If the angle of incidence is greater than the critical angle, defined by the relation _c = arcsin(n_cₗₐ_d_dᵢₙ_g / n_cₒᵣₑ), the light does not pass into the cladding but is instead reflected entirely back into the core. This continuous process of internal reflection allows light pulses to travel vast distances with minimal loss of signal strength, enabling high-speed telecommunications and medical imaging.

Explanation

Microsoft PowerPoint is the primary application within the Microsoft Office suite specifically designed for creating and delivering visual presentations. It allows users to organize information into individual slides that can incorporate text, graphics, charts, and multimedia elements such as audio and video. The software provides various tools for slide transitions, custom animations, and design templates, making it the standard tool for developing structured slide decks for professional, academic, or personal use.

Explanation

HyperText Markup Language (HTML) is the foundational language of the World Wide Web, developed by Tim Berners-Lee in 1989 while he was working at CERN. It was designed as a simple way to format documents and link them together using hyperlinks, allowing researchers to share information across different computer systems. From the very first web page launched in 1991, HTML served as the primary tool for structuring and displaying content on the internet, defining elements like headings, paragraphs, and links that browsers interpret to render web pages.

Explanation

Ethology is the scientific and objective study of animal behaviour, usually with a focus on behaviour under natural conditions, and viewing behaviour as an evolutionary adaptive trait. This branch of zoology combines laboratory and field science, maintaining strong links to other disciplines such as ecology and evolution. It seeks to understand the causes, functions, development, and evolution of behaviour by observing animals in their natural environments. Major advancements in this field were led by researchers like Konrad Lorenz and Nikolaas Tinbergen, who demonstrated how both innate and learned behaviours contribute to an organism's survival and reproductive success. This discipline specifically examines how animals interact with each other and their surroundings through complex social and biological mechanisms.

Explanation

A Barr body is a condensed, inactivated X chromosome found within the nucleus of female somatic cells. This structure results from the process of X-inactivation, also known as Lyonization, which occurs during early embryonic development in mammals. Because females possess two X chromosomes (XX), one of them is randomly silenced in each cell to ensure that the dosage of X-linked gene products is consistent with individuals possessing only one functional X chromosome. The inactivated chromosome becomes highly coiled into heterochromatin, making it visible under a microscope as a small, darkly stained mass typically located against the inner nuclear envelope. The existence of the Barr body is a direct consequence of this dosage compensation mechanism which requires the silencing of extra X chromosomes.

Explanation

The color of a star is primarily determined by its surface temperature, a relationship described by Wien's Displacement Law. According to this law, the wavelength ₘₐₓ at which an object emits the most radiation is inversely proportional to its absolute temperature T, expressed as ₘₐₓ = (b)/(T) where b is Wien's displacement constant. Since stars act as nearly perfect blackbodies, their thermal radiation produces a continuous spectrum where the peak wavelength dictates the perceived color. Hotter stars emit a greater proportion of their energy at shorter wavelengths, causing them to appear blue or white. Conversely, cooler stars emit peak radiation at longer wavelengths, making them appear orange or red. This physical principle allows astronomers to determine a star's effective surface temperature simply by analyzing its color or spectral class.

Explanation

Marine ecosystems are a primary source of complex natural products with therapeutic potential because marine organisms have evolved unique chemical defenses to survive in competitive underwater environments. Bryostatins are macrocyclic lactones derived from the marine bryozoan Bugula neritina, recognized for their ability to modulate protein kinase C and inhibit tumour growth. Dolostatins are potent antineoplastic peptides isolated from the marine mollusk Dolabella auricularia, commonly known as the sea hare. Both of these chemical classes are significant examples of marine-derived lead compounds that have undergone extensive clinical investigation for treating various forms of cancer.

Explanation

Chlorofluorocarbons (CFCs) are stable, man-made compounds that migrate to the stratosphere, where they are decomposed by intense ultraviolet radiation. This photodissociation process releases highly reactive chlorine atoms that act as catalysts in the breakdown of ozone (O₃) molecules into oxygen (O₂). A single chlorine atom can destroy thousands of ozone molecules through a chain reaction before being removed from the atmosphere, leading to a significant thinning of the ozone layer, particularly in polar regions. This depletion allows more harmful UV-B radiation to reach the Earth's surface.

Explanation

Recycling is the most sustainable and effective solution for managing non-biodegradable wastes such as plastics, glass, and metals because it facilitates the recovery of materials to create new products. Since these substances do not decompose through natural biological processes, they persist in the environment indefinitely. Recycling mitigates this by reintroducing the materials into the production cycle, which significantly reduces the demand for virgin raw materials and minimizes the overall environmental footprint. This approach conserves natural resources, saves energy compared to manufacturing from scratch, and prevents the long-term accumulation of hazardous pollutants in ecosystems.

Explanation

Vermicomposting is a biotechnology process that utilizes various species of earthworms to decompose organic waste into nutrient-rich manure. The term is derived from the Latin word vermis, meaning worm. In this process, earthworms such as Eisenia fetida or Eudrilus eugeniae ingest organic matter, which undergoes physical and chemical transformation within their digestive systems. The worms grind the material in their gizzards and mix it with digestive enzymes and microbes. The resulting excreta, known as worm castings, is a highly fertile organic fertilizer that contains concentrated levels of nitrogen, phosphorus, and potassium, while also improving the water-retention capacity and aeration of the soil.

Explanation

Typhoid fever is a life-threatening systemic infection caused by the bacterium Salmonella Typhi. It is a classic example of a waterborne disease that spreads through the fecal-oral route. This occurs when drinking water sources become contaminated with the waste materials, specifically the feces or urine, of an infected person or a chronic carrier. Once the contaminated water is ingested, the bacteria invade the intestinal mucosa and enter the bloodstream, leading to symptoms such as prolonged high fever, fatigue, headache, and abdominal pain. The prevalence of typhoid is closely linked to poor sanitation and the lack of clean drinking water supplies.

Explanation

India commenced the export of electricity to Bangladesh in October 2013 with the inauguration of the 400 kV Behrampur-Bheramara cross-border transmission link. This high-voltage connection allowed the Indian grid to supply an initial capacity of approximately 500 MW of power to Bangladesh to address its energy deficit. The power transfer is facilitated by NTPC Vidyut Vyapar Nigam Limited, which acts as the nodal agency for cross-border power trading. This partnership represents a key component of regional energy cooperation, fostering integration and assisting the socioeconomic development of Bangladesh through stable energy supplies.

Explanation

Caffeine is a naturally occurring methylxanthine alkaloid, chemically known as 1,3,7-trimethylxanthine, with the formula C₈H₁₀N₄O₂. It functions as a central nervous system stimulant and is produced by several plant species as a natural pesticide to protect against herbivorous insects. The most significant natural sources include the seeds of Coffea arabica (coffee beans), the seeds of Theobroma cacao (cocoa beans), and the seeds of various species of the Cola genus (cola nuts). It is also found in the leaves of the tea plant. In humans, it acts by antagonizing adenosine receptors in the brain, which leads to increased alertness and reduced perceived fatigue.

Explanation

Aluminium and its alloys are the primary materials used in aircraft and rocket construction due to their high strength-to-weight ratio, durability, and corrosion resistance. While nickel is used in specific engine parts, aluminium is the standard metal for the structural bodies.

Explanation

Vulcanization is a chemical process used to improve the physical properties of natural rubber or related polymers. By heating raw rubber with sulphur, cross-links are formed between the individual polymer chains. These sulphur bridges prevent the chains from sliding past each other easily, which significantly increases the elasticity, tensile strength, and durability of the material. This process transforms the naturally soft and sticky latex into a stable, tough material that remains flexible across a wide range of temperatures and is resistant to chemical abrasion.

Explanation

Madhya Pradesh is traditionally known as the Pulse Bowl of India and has consistently maintained its position as the largest producer of pulses in the country. Based on agricultural data available up to 2014, including the 2013-14 crop year, the state accounted for approximately 25 to 30 percent of India's total pulse production. This leadership is driven by the state's vast area under cultivation and favorable agro-climatic conditions for a variety of pulses, particularly gram (chickpea), which is the most significant contributor to the total pulse basket. The state's agricultural policy and focus on dryland farming have historically enabled it to lead the national output ahead of other major producing states.

Explanation

Maharashtra has never had a woman Chief Minister since its formation on May 1, 1960. While the state has a history of active female participation in social and political movements and has seen women serve as the Governor and in various cabinet-level positions, the office of the Chief Minister has been occupied exclusively by men. Throughout its political history, from its first Chief Minister Yashwantrao Chavan to the leaders in office up through 2014, the executive head of the state government has always been a male representative.

Explanation

Hydrogen is the first element in the periodic table and exists naturally as a highly reactive diatomic gas with the formula H₂. It possesses a single electron in its 1s orbital, meaning it lacks the full valence shell configuration that characterizes the noble gases of Group 18. While noble gases are chemically inert and monatomic due to their stable electron arrangements, hydrogen is highly chemically active and readily forms bonds with other elements to achieve stability.

Explanation

The Sunda Trench, which is also widely known as the Java Trench, is located in the northeastern part of the Indian Ocean. It is an oceanic trench that extends for approximately 3,200 kilometers, running parallel to the southern coast of the Indonesian islands of Sumatra and Java. Formed as a result of the subduction of the Indo-Australian Plate beneath the Sunda Plate, it represents the deepest part of the Indian Ocean, with its maximum depth reaching approximately 7,725 meters. This trench is a significant tectonic feature within the Sunda Arc and is associated with frequent seismic and volcanic activity in the region.

Explanation

Coal is classified as an organic sedimentary rock because it is formed from the accumulation and lithification of plant remains, primarily in swampy or forested environments. Over geological time scales, these layers of organic matter are buried under sediment, where they are subjected to high pressure and heat. This process, known as coalification, removes water and volatile components while concentrating carbon. Because its fundamental composition is derived from the remains of living organisms rather than mineral precipitates or rock fragments, it is defined as a biogenic or organic rock.

Explanation

R.K. Narayan is the author of the renowned collection of short stories titled Malgudi Days, first published in 1943. The book features various stories centered around the daily lives of the residents of Malgudi, a fictional town in South India that Narayan created as the setting for most of his literary works. His writing style is celebrated for its simplicity, gentle irony, and perceptive depiction of the social fabric of middle-class India. The enduring popularity of the book led to its adaptation into a highly successful television series in the 1980s, which further cemented the characters and the setting in Indian cultural memory.

Explanation

The Government of India Act 1858 was enacted by the British Parliament in the immediate aftermath of the Indian Rebellion of 1857. This legislation liquidated the East India Company and transferred its functions to the British Crown. The Act mandated that India was to be governed directly by and in the name of the Queen. It established the office of the Secretary of State for India, who was assisted by a Council of India, and designated the Governor-General as the Viceroy to serve as the direct representative of the Crown. On November 1, 1858, Lord Canning announced this change of sovereignty at a grand Darbar in Allahabad through the Queen's Proclamation, marking the beginning of the British Raj.

Explanation

The pulmonary vein is the blood vessel responsible for transporting oxygenated blood from the lungs to the left atrium of the heart. While veins typically carry deoxygenated blood toward the heart, the pulmonary veins are unique because they carry blood that has been replenished with oxygen and cleared of carbon dioxide in the pulmonary capillaries. Once this oxygen-rich blood reaches the left side of the heart, it is ready to be pumped into the systemic circulation to provide oxygen to the tissues of the body.

Explanation

Annie Besant presided over the Calcutta session of the Indian National Congress in 1917, making her the first woman to hold the office of President in the history of the organization. An influential theosophist and supporter of Indian self-rule, she played a pivotal role in the Indian independence movement by founding the Home Rule League in 1916. Her leadership during this period and her efforts to bridge the gap between various factions of the Congress led to her election to the presidency, marking a significant milestone for women's participation in Indian political leadership.

Explanation

The Average Propensity to Consume (APC) is an economic measure that represents the fraction of total income that is spent on consumption. It is defined as the ratio of aggregate consumption expenditure to aggregate income. The formula for calculating this value is APC = (C)/(Y), where C denotes the total consumption in the economy and Y denotes the total national income. This ratio indicates what percentage of a given level of income is being used for purchasing goods and services rather than being saved.

Explanation

In the short run, a firm in a competitive market will continue to operate even if it is making a loss, provided the price is high enough to cover its average variable costs. This minimizes losses because the firm can contribute some revenue toward its fixed costs, which must be paid regardless of production levels.

Explanation

The single member constituency system, often associated with the First-Past-The-Post electoral method, facilitates the creation of a stable majority in the legislature by favoring larger political parties. Because only one representative is elected from each district, the system tends to consolidate representation into a two-party or dominant-party structure. This prevents the fragmentation of the legislature into numerous small parties, making it more likely for a single party to secure a clear mandate to form a government. The resulting legislative homogeneity ensures that the executive can maintain consistent support for its policies and survive its full term without the instability typically found in multi-party coalition governments.

Explanation

In macroeconomic theory and national income accounting, total income Y is fundamentally divided into two parts based on its utilization: consumption C and saving S. This relationship is expressed by the identity Y = C + S. Since saving is defined as the portion of disposable income that is not spent on the consumption of goods and services, this equation holds true by definition at all times. It reflects the basic accounting principle that all income earned by households must either be used for current expenditures or set aside for future use.

Explanation

The Keynesian consumption function describes the functional relationship between aggregate consumption and aggregate income. According to John Maynard Keynes' Fundamental Psychological Law, as aggregate income increases, aggregate consumption also increases, but by a smaller proportion than the increase in income. This relationship is mathematically expressed as C = a + bY, where C represents aggregate consumption, a denotes autonomous consumption (spending that occurs even when income is zero), b is the marginal propensity to consume (0 < b < 1), and Y represents aggregate disposable income. In the Keynesian framework, current disposable income is the primary determinant of consumer spending in the short run.

Explanation

The Average Propensity to Consume (APC) is the ratio of total consumption expenditure to total income, represented by the formula APC = C/Y. According to Keynes's psychological law of consumption, as income increases, consumption also increases but not at the same rate; specifically, the increase in consumption is less than the increase in income. In the short-run consumption function, C = C + cY, the term C represents autonomous consumption, which remains positive even when income is zero. When calculating APC from this function, the formula becomes APC = C/Y + c, where c is the Marginal Propensity to Consume. As income Y rises, the value of the fraction C/Y mathematically decreases. Since the Marginal Propensity to Consume c is typically constant in the short run, the total value of the APC must fall as income grows. This reflects the fact that at higher income levels, individuals tend to save a larger proportion of their income, thereby reducing the share of income dedicated to consumption.
