SSC CGL Tier 1 2014 General Awareness Questions with Solutions

Explanation

Keynesian economics is fundamentally centered on the concept of effective demand, which asserts that the total level of economic activity and employment in an economy is determined by the total volume of spending, or aggregate expenditure. Keynesian theory posits that fluctuations in expenditure—comprising consumption, investment, and government spending—are the primary drivers of business cycles. During periods of economic downturn, the theory suggests that private demand may be insufficient to maintain full employment, necessitating active intervention through increased government expenditure to stimulate demand and restore economic equilibrium. The central formula for aggregate demand, AD = C + I + G + (X - M), illustrates that output is a function of total spending across these various sectors.

Explanation

Decentralisation is the defining characteristic of a federal state because it involves the constitutional distribution of power between the central government and various constituent units, such as states or provinces. In a federal system, authority is not concentrated in a single central body but is dispersed across multiple levels of governance, each possessing its own sphere of jurisdiction as guaranteed by the constitution. This vertical division of power ensures that regional governments maintain autonomy and the right to legislate on specific matters, thereby preventing the monopolization of power and facilitating administrative efficiency tailored to local needs. This structural dispersal of authority is what fundamentally distinguishes federalism from a unitary system.

Explanation

Public opinion refers to the collective consensus or the dominant view held by the population on issues of common concern. In a democratic system, it is difficult to achieve a unanimous viewpoint among all individuals; therefore, the most effective and widely accepted expression of the public will is the majority opinion. This majority view acts as a powerful force in shaping government policies, as it represents the prevailing sentiment of the largest section of the community and serves as a functional indicator of the popular will in the political process.

Explanation

In the Union Budget of India, current expenditure refers to revenue expenditure, which encompasses the recurring costs of administration and service delivery. Interest payments on the government's accumulated internal and external debt consistently represent the largest single item within this category. This is a non-discretionary expenditure that the government must prioritize to maintain fiscal credibility and service the borrowings used to fund previous fiscal deficits. During the 2014-15 period, interest payments accounted for approximately 20 percent of the total expenditure and a substantial portion of the revenue receipts, making it the most significant component of non-plan revenue expenditure. This high allocation is a direct consequence of the historical reliance on market borrowings to bridge the gap between government revenue and spending.

Explanation

The demand for a factor of production is termed derived demand because it originates from the demand for the final goods and services that the factor helps to produce. Unlike consumer goods, which are demanded for direct satisfaction or utility, factors such as labor, land, and capital are demanded by firms as inputs in the production process. A producer's requirement for these inputs is essentially a consequence of the market demand for the finished product. For example, the demand for steel workers is derived from the demand for automobiles or construction projects. If the demand for the final output rises, the demand for the necessary factors of production will increase accordingly to meet the production requirements.

Explanation

Vijaya Lakshmi Pandit was elected as the President of the United Nations General Assembly in 1953 for its eighth session. This appointment made her the first woman to ever hold the position of President in the history of the UN General Assembly. A prominent Indian diplomat and politician, she had a distinguished career that included serving as India's ambassador to the Soviet Union, the United States, and as the High Commissioner to the United Kingdom. Her leadership at the United Nations remains a landmark event in international relations and global gender representation.

Explanation

The Pancha-siddhantika, authored by the 6th-century polymath Varahamihira, is a seminal treatise on mathematical astronomy. It functions as a compendium of five earlier astronomical systems known as the Paitamaha, Vashistha, Romaka, Paulisa, and Surya Siddhantas. The work provides sophisticated mathematical methods for calculating the positions of planets, predicting the occurrence and duration of solar and lunar eclipses, and determining the passage of time through celestial observation. By synthesizing these diverse traditions, Varahamihira preserved ancient scientific knowledge and established a rigorous framework for astronomical calculations in the Indian scientific tradition.

Explanation

The silver coins issued during the Gupta period were known as Rupyakas. These coins were first introduced by Chandragupta II, also known as Vikramaditya, following his successful military campaign against the Shaka Kshatrapas of Western India. Because the newly conquered territories in Malwa and Saurashtra were accustomed to silver currency, the Gupta state minted Rupyakas to maintain economic stability and facilitate trade in those regions. The name is derived from the Sanskrit word rupya, meaning silver. These coins were modeled after the silver drachms of the Western Satraps, featuring the kings portrait on the obverse and symbols like the peacock or the Garuda on the reverse, generally weighing between 30 and 32 grains.

Explanation

Lothal is located in the Saragwala village of Dholka Taluka in the Ahmedabad district of Gujarat. Situated near the Gulf of Khambhat, it served as a vital maritime trade center for the Indus Valley Civilization. The site is most famous for its artificial brick dockyard, which was connected to the Sabarmati River through a canal. This dockyard allowed for the berthing of ships and facilitated trade with contemporary civilizations like Mesopotamia. Excavated by S.R. Rao in 1954, Lothal provides significant evidence regarding the urban planning and maritime capabilities of the Harappan people in the western part of the Indian subcontinent.

Explanation

Qutbuddin Aibak was the founder of the Mamluk dynasty and the first Sultan of Delhi, reigning from 1206 to 1210 AD. In 1210, while playing a game of Chaugan, which is an early form of polo, at Lahore, he suffered a fatal accident. His horse tripped and fell, throwing him to the ground, and he was impaled by the high pommel of his saddle. Following this sudden fall and the resulting internal injuries, he passed away and was buried in Lahore.

Explanation

The term Buddha is derived from the Sanskrit root budh, which means to awaken, to know, or to perceive. It literally translates to the Awakened One or the Enlightened One. This title was given to Siddhartha Gautama after he attained supreme spiritual realization and perfect wisdom under the Bodhi tree at Bodh Gaya. In Buddhist philosophy, a Buddha is someone who has fully awakened from the slumber of ignorance, cleared all obscurations of the mind, and realized the ultimate truth of existence, thereby ending the cycle of rebirth and suffering.

Explanation

Fundamental Duties were incorporated into Part IV-A, Article 51A of the Indian Constitution through the 42nd Amendment Act, 1976, following the recommendations of the Swaran Singh Committee. Article 51A(h) specifically identifies the duty to develop the scientific temper, humanism, and the spirit of inquiry and reform. This provision mandates that every citizen should strive to adopt a rational, analytical, and objective approach toward life and social issues, while simultaneously promoting human values and a constant desire for social improvement through questioning and critical thinking. It aims to create a society rooted in reason rather than dogma or superstition.

Explanation

Hindustan Zinc Limited (HZL) is headquartered in Udaipur, Rajasthan. It was established in 1966 as a public sector enterprise to develop the zinc and lead mining industry in India. The company's headquarters are located in Udaipur because the city is centrally positioned relative to the primary zinc-lead mineral belt in Rajasthan, including major deposits such as the Zawar Mines, Rajpura Dariba, and Rampura Agucha. HZL is now a subsidiary of Vedanta Limited and remains the country's only integrated producer of zinc, lead, and silver.

Explanation

Fallowing is a traditional agricultural practice where a piece of land is left uncropped for a specific period, ranging from one season to several years. This technique is primarily used to restore soil fertility and health naturally. During the fallow period, organic matter decomposes and the soil accumulates essential nutrients like nitrogen and phosphorus that were depleted during previous cultivation cycles. Additionally, leaving the land uncultivated helps in the conservation of soil moisture and disrupts the life cycles of various pests and soil-borne pathogens. This process ensures that the land remains productive for future agricultural use without excessive reliance on external inputs.

Explanation

Rayleigh scattering occurs when sunlight passes through the atmosphere and interacts with gas molecules and particles that are much smaller than the wavelength of the incident light. The intensity of this scattering I is inversely proportional to the fourth power of the wavelength λ, as defined by the relation I ∝ (1)/(λ⁴⁾. Within the visible spectrum, blue light has a significantly shorter wavelength than red light. Consequently, the shorter blue wavelengths are scattered much more efficiently in all directions by the nitrogen and oxygen molecules in the air. When an observer looks at the sky, this scattered blue light reaches their eyes from every direction, which is why the sky appears blue.

Explanation

Block mountains are formed when the Earth's crust is subjected to powerful tectonic forces of tension. These tensional forces cause the crust to fracture, leading to the creation of faults. When large blocks of the Earth's crust are displaced vertically along these fault lines, the uplifted blocks are known as Block mountains or Horsts. This process typically occurs when the crust is being pulled apart, causing sections of the land to subside or rise relative to one another. The sunken blocks between the parallel faults are called rift valleys or grabens. Examples of mountains formed through this tensional faulting process include the Vosges and Black Forest mountains in Europe and the Sierra Nevada in North America.

Explanation

Drosera, commonly known as the sundew, is a carnivorous plant that utilizes specialized glandular hairs or tentacles on its leaves to capture prey. These hairs are highly sensitive to mechanical stimuli. When an insect lands on the leaf and comes into contact with the tentacles, the stimulus of touch triggers a directional movement where the hairs bend toward the source of contact. This response to the stimulus of physical touch is known as thigmotropism.

The movement is initiated by sensory cells at the tip of the tentacle which perceive the pressure of the insect. This signal is transmitted to the lower parts of the hair, leading to differential growth or turgor pressure changes that cause the tentacle to curve inward. This mechanism ensures that the prey is tightly held and moved toward the center of the leaf, where it is smothered by mucilage and subsequently broken down by digestive enzymes for nutrient absorption.

Explanation

Cephalerous (more commonly spelled Cephaleuros) is a genus of parasitic green algae belonging to the family Trentepohliaceae. While most algae are free-living and autotrophic, this genus is a notable exception that lives parasitically on the leaves, fruits, and stems of various vascular plants. It is the primary causal agent of red rust disease, which significantly affects economically important crops such as tea, coffee, mango, and citrus. The alga typically grows beneath the host's cuticle or within its tissues, where it can cause necrosis and reduce the host's photosynthetic capacity, leading to weakened plant health and reduced yields.

Explanation

Gardenia exhibits a solitary cymose inflorescence, which represents the most simplified or reduced form of the cymose pattern. In this arrangement, the growth of the floral axis is determinate because the apical meristem is completely utilized in the formation of a single flower. This flower typically appears at the tip of the branch (solitary terminal) or in the axil of a leaf (solitary axillary). Because the main axis terminates in a flower bud and no subsequent flowers are produced on that same peduncle, it is classified as a solitary cyme, effectively limiting the longitudinal growth of that particular reproductive shoot.

Explanation

In Paramoecium, the elimination of undigested food materials occurs through a specific, permanent opening in the pellicle called the cytopyge or cytoproct, often referred to as the cytopype. This aperture is located on the ventral surface of the organism, posterior to the cytostome. After the food vacuole completes its circulation through the cytoplasm and all useful nutrients are absorbed, the vacuole containing the waste moves toward this fixed point. The vacuole membrane then fuses with the plasma membrane at the cytopyge to discharge the fecal matter into the external environment through the process of egestion.

Explanation

Patrick Steptoe and Robert Edwards were the pioneers responsible for the development of the In Vitro Fertilization technique. Working together in the United Kingdom during the 1960s and 1970s, they achieved the first successful human conception through IVF, which resulted in the birth of Louise Joy Brown on July 25, 1978. Robert Edwards, a physiologist, focused on the biological aspects of fertilizing human eggs outside the body, while Patrick Steptoe, a gynecologist, utilized laparoscopy to retrieve the eggs from the ovaries. Their groundbreaking work provided a medical solution for infertility and laid the foundation for modern reproductive medicine. Robert Edwards was later awarded the Nobel Prize in Physiology or Medicine in 2010 for this achievement.

Explanation

Biodiversity refers to the variety and variability of all living organisms, including plants (flora) and animals (fauna), within a specific ecosystem or habitat. It is a measure of the richness of species found in a particular area, such as a forest, representing the complexity and health of that biological environment. The term highlights the coexistence of a wide range of different life forms within a single ecological unit.

Explanation

In uniform circular motion, a particle moving at a constant speed v along a path of radius r experiences centripetal acceleration. This acceleration is directed toward the center of the circle and is calculated using the formula v²/r.

Explanation

A thermopile is an electronic device used for detecting and measuring radiant heat (thermal radiation) by converting thermal energy into electrical energy. It consists of several thermocouples connected in series, which amplifies the resulting electromotive force (EMF) produced via the Seebeck effect. One set of junctions is typically blackened to maximize the absorption of incident radiation, while the other set remains shielded as a reference. When radiant energy falls on the active junctions, a temperature gradient is established, generating a measurable voltage proportional to the intensity of the radiant heat. This high sensitivity to infrared radiation makes it an essential tool in radiometry and non-contact temperature measurement.

Explanation

The formation of a rainbow is an optical phenomenon caused by the combination of refraction, dispersion, and total internal reflection of sunlight within spherical water droplets. When sunlight enters a raindrop, it is refracted and dispersed into its constituent spectrum of colors. This light travels to the back surface of the droplet and strikes it at an angle greater than the critical angle for the water-air interface. The light undergoes total internal reflection, which directs it back toward the front of the drop. As the light exits the droplet, it undergoes a final refraction, which further separates the colors and directs them toward the observer, resulting in the characteristic multi-colored arc in the sky.

Explanation

The period of oscillation T for an electromagnetic wave is related to its wavelength λ and the speed of light c by the formula T = λ / c. Given the wavelength of the microwave is 3 cm, which is 3 × 10⁻² m, and the speed of light is approximately 3 × 10⁸ m/s, the period is calculated as T = (3 × 10⁻² m) / (3 × 10⁸ m/s). This simplifies to 1 × 10⁻¹⁰ seconds.

Explanation

EEPROM stands for Electrically Erasable Programmable Read-Only Memory and represents the most sophisticated stage in the evolution of ROM technology. Unlike previous versions that were either permanent once programmed or required specialized ultraviolet light equipment for erasure, EEPROM allows data to be erased and rewritten electrically. A key advantage of this technology is its ability to be modified at the byte level without being removed from the computer or device. This flexibility makes it the standard choice for storing BIOS firmware and other critical system configurations that need to be updated periodically while maintaining non-volatile storage characteristics.

Explanation

An interpreter is a language processor that translates high-level programming code into machine language in a sequential manner, processing one instruction at a time. As it reads each line of the source code, it immediately converts it into an intermediate form or machine code and executes it before moving to the next line. This real-time translation process allows the program to run step-by-step, making it easier to identify specific lines where errors occur during the execution phase.

Explanation

Sodium is a highly reactive alkali metal that reacts vigorously with both atmospheric oxygen and moisture. When exposed to air, it quickly oxidizes to form sodium oxide, and when in contact with water, it undergoes a violent exothermic reaction to produce sodium hydroxide and hydrogen gas, as shown by the equation 2Na + 2H₂O → 2NaOH + H₂. The heat generated in this reaction is often sufficient to ignite the hydrogen gas. To prevent these spontaneous reactions and ensure safety, sodium is stored immersed in kerosene. Kerosene is a mixture of hydrocarbons that is chemically inert toward the metal and provides a protective barrier that excludes air and water vapor.

Explanation

The normal respiratory rate for a healthy newborn (neonate) typically ranges from 30 to 60 breaths per minute. This rate is significantly higher than that of adults because infants have a higher metabolic rate, smaller lung volumes, and higher oxygen consumption requirements per unit of body weight. During the first few hours of life, the respiratory system undergoes a transition from fetal to neonatal circulation, and a rate of 32 breaths per minute falls squarely within the stable physiological range expected for a just-born baby. This rapid breathing ensures sufficient gas exchange to meet the high demands of the developing body.

Explanation

As one moves from left to right across a period in the periodic table, the atomic number increases, which signifies an increase in the number of protons in the nucleus. This results in a higher effective nuclear charge. Since the additional electrons are being added to the same principal energy level or shell, they do not provide significant shielding against the increasing nuclear pull. Consequently, the stronger electrostatic attraction from the nucleus draws the electron cloud closer to the center, leading to a contraction of the atom and a decrease in the atomic radius.

Explanation

Vulcanization is a chemical process where natural rubber is heated with sulfur to enhance its physical properties. The process works by introducing sulfur atoms that create cross-links between the long polyisoprene polymer chains. This cross-linking prevents the chains from sliding past each other too easily, which increases the material's elasticity, tensile strength, and durability while reducing its stickiness. In the production of standard vulcanized rubber used for industrial and consumer goods, a sulfur concentration of 3-5% is typically employed. This specific range provides the necessary structural stability and resilience for the rubber to maintain its shape under stress and varying temperatures without becoming overly rigid or brittle.

Explanation

Birds are uricotelic organisms, meaning they excrete their nitrogenous waste primarily in the form of uric acid. This is a critical physiological adaptation for water conservation and flight. Uric acid is the least toxic of the nitrogenous wastes and is highly insoluble in water, which allows it to be excreted as a semi-solid paste or pellet with very little water loss. This efficiency in water management is essential for birds to maintain a light body weight for flight and to survive in environments where water may be scarce.

Explanation

The Marine National Park in the Gulf of Kutch, located along the southern coast of the Gulf of Kutch in Gujarat, was the first marine area in India to be granted such a status. It was initially declared a Marine Sanctuary in 1980 and subsequently upgraded to a Marine National Park in 1982 under the Wildlife (Protection) Act, 1972. The designation was specifically aimed at conserving the diverse marine life of the region, particularly its extensive fringing coral reefs, which are among the few coral ecosystems found in mainland India. This legal framework provides strict protection to the corals and their surrounding habitats, including mangroves and sea grasses, from commercial exploitation and environmental degradation.

Explanation

Guard cells are specialized, modified epidermal cells that exist in pairs to enclose and regulate each stomatal pore. Unlike most other epidermal cells, guard cells contain chloroplasts and feature differentially thickened cell walls, where the wall adjacent to the pore is thick and inelastic while the outer wall is thin and elastic. They function by altering their turgor pressure through the movement of water and ions; when the cells become turgid, they curve outward to open the pore, and when they lose water and become flaccid, the pore closes, thereby managing gas exchange and transpiration.

Explanation

The term foliar is derived from the Latin word folium, which means leaf. In botany, foliar refers to any process or structure related to the leaves of a plant. Since the majority of a plant's water loss occurs through the leaf surfaces via stomata and the cuticle, the collective process of water evaporation from the leaves is biologically classified as foliar transpiration. This process is essential for creating the transpirational pull required for the upward movement of water and minerals from the roots and for regulating the temperature of the plant tissues.

Explanation

Explanation

As per the production data from the Cotton Advisory Board for the 2013-14 crop year, Gujarat was the leading cotton-producing state in India. During this period, Gujarat produced approximately 124 lakh bales (each bale weighing 170 kg), contributing nearly 31 percent of the country's total cotton output. The state's high productivity is attributed to the widespread adoption of Bt cotton, favorable agro-climatic conditions in the Saurashtra and North Gujarat regions, and better irrigation facilities compared to other states. The black soil prevalent in these regions provides the necessary moisture retention required for cotton cultivation, allowing Gujarat to maintain the highest yield per hectare in the country during this timeframe.

Explanation

The 'More' retail chain was owned and operated by Aditya Birla Retail Limited (ABRL), a subsidiary of the Aditya Birla Group. The group established its presence in the Indian retail sector in 2007 through the acquisition of Trinethra Super Retail and subsequently launched its own brand, 'More'. By 2014, the chain operated through two main formats: 'More' for supermarkets and 'More Megastore' for large-scale hypermarkets, positioning the Aditya Birla Group as a major competitor in the organized retail market in India.

Explanation

Swami Vivekanand was a central figure in the spiritual and cultural awakening of modern India and is widely credited with the revival of Hinduism in the late 19th century. He interpreted ancient Vedantic philosophy in a contemporary context known as Practical Vedanta, making it relevant to modern life. By representing India at the 1893 World Parliament of Religions in Chicago, he brought global recognition and prestige to Hindu spiritual traditions. Through the establishment of the Ramakrishna Mission in 1897, he integrated the pursuit of spiritual salvation with dedicated social service and education. His teachings instilled a sense of self-respect and national pride in the Indian people regarding their heritage, effectively transforming Hinduism into a dynamic and socially conscious force that laid the foundation for modern Indian nationalism.

Explanation

The Nobel Peace Prize is awarded in Oslo, Norway, in accordance with the 1895 will of Alfred Nobel. While the prizes for Physics, Chemistry, Physiology or Medicine, and Literature are awarded in Stockholm, Sweden, Nobel specifically designated that the Peace Prize should be awarded by a committee appointed by the Norwegian Parliament. The ceremony takes place annually on December 10 at the Oslo City Hall to mark the anniversary of Alfred Nobel's death.

Explanation

The International Olympic Committee (IOC) has its headquarters located in Lausanne, Switzerland. Founded in 1894 by Pierre de Coubertin and Demetrios Vikelas, the organization moved its administrative center from Paris to Lausanne in 1915 to ensure its neutrality during World War I. In recognition of this long-standing relationship, Lausanne was officially designated as the Olympic Capital in 1994. The IOC functions as the supreme authority of the Olympic Movement and is responsible for organizing the modern Summer and Winter Olympic Games.

Explanation

The Wildlife (Protection) Act was enacted by the Parliament of India in 1972 to provide a comprehensive legal framework for the protection of wild animals, birds, and plants. Prior to this act, India had limited legislation regarding wildlife, mostly at the state level. The 1972 Act established various schedules of protected species, ranging from those requiring absolute protection to those that can be hunted under specific conditions. It also empowered the central and state governments to declare areas as National Parks and Wildlife Sanctuaries, prohibiting hunting and regulating human activities within these protected zones to ensure the conservation of biodiversity and ecological security.

Explanation

Arkose is a clastic sedimentary rock, specifically a variety of sandstone that contains at least 25% feldspar. It is formed through the mechanical weathering and disintegration of silicate-rich rocks, followed by the rapid deposition, burial, and lithification of the resulting mineral fragments. Because its components are mineral grains that have been transported and deposited in layers before being cemented together, it is classified within the sedimentary category.

Explanation

Plantation agriculture is a form of commercial farming where a single cash crop is grown on a large scale for sale in the market. This system is highly specialized and capital-intensive, requiring large estates, modern scientific methods, and efficient transport systems to link the estates with processing factories. Common crops grown under this system include tea, coffee, rubber, cocoa, sugarcane, and bananas. These plantations are typically found in tropical and subtropical regions and were often established by colonial powers to ensure a steady supply of raw materials for global trade.
