SSC CHSL Tier 1 2013 General Awareness Questions with Solutions

Explanation

A supply function mathematically represents the relationship between the price of a commodity and the quantity of that commodity that producers are willing and able to offer for sale, which constitutes the output. Typically written as Q = f(P), where Q represents the quantity supplied (output) and P represents the market price, it illustrates how the level of production responds to changes in price. Under the law of supply, this relationship is direct and positive, meaning that higher prices incentivize producers to increase their output to maximize profits, assuming all other factors remain constant.

Explanation

Final goods refer to those goods that have crossed the boundary line of production and are ready for use by their final users. These goods are classified based on their ultimate end-use. If they are purchased by households to satisfy their immediate wants, they are classified as consumer goods meant for final consumption. If they are purchased by firms for capital formation, such as machinery, tools, or buildings, they are classified as capital goods meant for investment. Both categories do not undergo any further processing or resale in the production process.

Explanation

Monetary policy refers to the macroeconomic policy laid down by a central bank to manage the money supply, interest rates, and credit availability in an economy. The central bank uses quantitative instruments to achieve these objectives. The Cash Reserve Ratio is the specific percentage of total deposits that commercial banks must keep as liquid cash with the central bank, directly influencing the amount of credit banks can create. Open Market Operations involve the buying and selling of government securities in the open market by the central bank to regulate the liquidity in the banking system. Both of these tools are used to control inflation, stabilize the currency, and promote economic growth.

Explanation

The famous quote "Man is a social animal" is attributed to the ancient Greek philosopher Aristotle. In his seminal work, Politics, he asserted that human beings are by nature political and social creatures (zoon politikon). Aristotle argued that individuals are not self-sufficient and cannot lead a complete or moral life in isolation. According to his philosophy, the state and society exist to satisfy the natural human need for companionship, cooperation, and mutual development, making social living an inherent characteristic of humanity.

Explanation

Marginal cost is defined as the incremental cost incurred by producing one additional unit of a good or service. Mathematically, it is calculated by taking the change in total cost and dividing it by the change in the quantity of output.

The formula for marginal cost is:

MC = ΔTC ÷ ΔQ

where MC represents marginal cost, ΔTC represents the change in total cost, and ΔQ represents the change in quantity. This ratio measures the rate at which total cost varies as the level of production changes.

Explanation

In microeconomics, market structures are classified along a spectrum based on the degree of competition and pricing power. The two polar extremes of this market spectrum are perfect competition and monopoly. Perfect competition represents one extreme where a vast number of firms sell identical products, entry and exit are entirely free, and firms are price takers with zero market power. On the opposite end of the spectrum lies a monopoly, which is characterized by a single seller of a unique product with no close substitutes, high barriers to entry, and absolute price-making power. All other market structures represent intermediate forms that lie between these two theoretical extremes.

Explanation

Under Article 75 of the Constitution of India, the President appoints the Prime Minister. While the President normally appoints the leader of the party or coalition that commands a majority in the Lok Sabha, situational discretion arises when no single party or pre-poll alliance secures a clear majority, or if the incumbent Prime Minister dies suddenly in office without an obvious successor. In such scenarios, the President exercises personal discretion to select and appoint a candidate who, in their opinion, is most likely to command the confidence of the Lok Sabha and form a stable government.

Explanation

The script of the Indus Valley Civilization, often found on seals, pottery, and amulets, is pictographic in nature and has not been successfully decoded or translated by linguists and historians. Although it consists of hundreds of unique symbols written mostly from right to left, a lack of bilingual texts or a Rosetta Stone equivalent has made it impossible to read, meaning it remains completely undeciphered.

Explanation

Krishna Devaraya, the celebrated emperor of the Vijayanagara Empire who ruled from 1509 to 1529, was a highly accomplished scholar, poet, and patron of arts and literature. He authored the famous Telugu epic Amuktamalyada, which is written as Anukta Malayada in the choices. This literary masterpiece describes the story of the wedding of the south Indian Alwar saint Andal to Lord Ranganatha. The work is widely recognized as one of the greatest classics of Telugu literature and contains extensive descriptions of the administration, polity, and social life during the peak of the Vijayanagara Empire.

Explanation

Satyagraha, developed by Mahatma Gandhi, is a method of non-violent resistance to combat injustice and oppression. The three primary and most widely practiced forms of Satyagraha during the Indian national movement were non-cooperation, civil disobedience, and boycott. Non-cooperation entails the active withdrawal of support and cooperation from an unjust government or authority. Civil disobedience involves the deliberate, peaceful refusal to obey specific unjust laws, decrees, or orders of the state. Boycott refers to the collective abstention from purchasing, using, or engaging with foreign goods, government institutions, and services as a peaceful expression of protest.

Explanation

Article 360 of the Constitution of India empowers the President of India to proclaim a Financial Emergency if they are satisfied that a situation has arisen whereby the financial stability or credit of India, or any part of its territory, is threatened. During the period of a Financial Emergency, the executive authority of the Union extends to giving directions to any State to observe specified canons of financial propriety, and the President may issue directions for the reduction of salaries and allowances of all or any class of persons serving in connection with the affairs of the Union or a State, including the Judges of the Supreme Court and the High Courts.

Explanation

Stock exchanges and futures markets is a subject listed under Entry 48 of the Union List (List I) in the Seventh Schedule of the Constitution of India. Because it falls under the Union List, only the Parliament of India has the exclusive power to make laws on this subject, meaning it does not feature in the Concurrent List (List III).

Explanation

The Grand Canyon is a steep-sided canyon carved by the Colorado River in the state of Arizona, United States. Over millions of years, the Colorado River and its tributaries cut their channels through layer after layer of rock of the Colorado Plateau, creating this massive and visually stunning geological formation.

Explanation

The English East India Company was incorporated by a royal charter from Queen Elizabeth I on 31 December 1600. At this time, the Mughal Empire in India was ruled by Akbar, whose reign spanned nearly five decades from 1556 until his death in 1605.

Explanation

The Indian National Congress was founded in December 1885 during the Viceroyalty of Lord Dufferin, who served from 1884 to 1888. Lord Curzon's tenure as Viceroy of India occurred much later, spanning from 1899 to 1905.

Explanation

Maximilien Robespierre was the leading figure of the Committee of Public Safety, which exercised virtual dictatorial control over France during the Reign of Terror from 1793 to 1794. He advocated for the use of terror to protect the democratic republic, leading to the arrest and execution of tens of thousands of suspected enemies of the revolution. His influence and policies came to define this period of radical violence and political purge, which ended with his own arrest and execution in July 1794.

Explanation

The highest waterfall in India is Kunchikal Falls, located in the Shimoga district of Karnataka. Formed by the Varahi River, this tiered waterfall cascades down from a total height of 455 meters. Jog Falls, which is traditionally celebrated as one of the highest plunge waterfalls in the country with a vertical drop of 253 meters, is also located on the Sharavati River in the Shimoga district of Karnataka.

Explanation

Laterite soil is formed in tropical and subtropical regions with hot and humid climates under conditions of heavy seasonal rainfall. The intense rainfall promotes rapid and severe leaching, a process wherein soluble minerals, organic matter, silica, and lime are washed away down into the lower layers of the soil. This leaves the topsoil rich in insoluble hydrated oxides of iron and aluminum, which give the soil its characteristic red color and make it acidic and poor in nutrients.

Explanation

Mushroom rocks, also known as pedestal rocks, are formed in desert environments primarily due to the process of wind abrasion. Wind-carried sand grains and particles collide with the lower portion of an isolated rock outcrop. Because sand-sized particles are relatively heavy, wind can only lift them to a limited height, typically within 1 meter of the ground. Consequently, the abrasive action of these high-velocity particles is concentrated near the base of the rock, wearing it away much faster than the upper portion and resulting in a mushroom-like shape with a narrow stem and a wider cap.

Explanation

Hydroponics is a method of growing plants in a nutrient-rich, water-based solution instead of using soil. In this technique, the plant roots are directly suspended in or supplied with an aqueous solution containing all the essential mineral nutrients required for their growth, completely bypassing the need for natural soil.

Explanation

Fungi are non-green heterotrophic organisms that lack chlorophyll, which means they are unable to perform photosynthesis. In traditional classification systems, they were placed in the plant kingdom because of their plant-like characteristics, such as having cell walls and being immobile. Since they cannot synthesize their own organic food, they rely on absorbing nutrients from decomposing organic matter or living hosts, making them heterotrophic.

Explanation

The hypothalamus gland, located at the base of the brain, acts as the primary link between the endocrine and nervous systems. It regulates the secretion of hormones from the pituitary gland by producing releasing and inhibiting hormones. These regulatory substances travel through the hypophyseal portal system to the anterior pituitary, where they stimulate or suppress the production and release of pituitary hormones. The hypothalamus also synthesizes oxytocin and antidiuretic hormone, which are transported to and stored in the posterior pituitary before release.

Explanation

The spleen serves as the primary site for the filtration, destruction, and recycling of old, worn-out, and damaged red blood cells. Red blood cells typically have a lifespan of about 120 days, after which their cell membranes lose flexibility and become fragile. When these aging cells attempt to squeeze through the narrow, tight spaces of the splenic sinusoids, they rupture. Specialized phagocytic cells called macrophages in the spleen then engulf and digest the cellular debris, recycling valuable components like iron to be reused by the body for new hemoglobin synthesis.

Explanation

The subtropical high-pressure belts, situated at approximately 30° to 35° latitude in both the Northern and Southern hemispheres, are commonly referred to as the horse latitudes. These regions are characterized by high atmospheric pressure, descending air, calm winds, and very low precipitation. Historically, Spanish sailing vessels carrying horses to the Americas frequently became becalmed in these areas of stagnant air. As these delays depleted their fresh water supplies, crews often had to throw their horses overboard to conserve water, giving rise to the name horse latitudes.

Explanation

Self-pollination is the transfer of pollen grains from the anther to the stigma of either the same flower or another flower on the same plant. Because the male and female gametes are derived from the same genetic parent, this process involves the fusion of closely related genetic material. Consequently, self-pollination increases homozygosity across generations, which directly leads to inbreeding. Continuous self-pollination over multiple generations intensifies this genetic uniformity.

Explanation

Spreadsheets use a coordinate system of columns and rows to identify individual cells. Columns are represented by alphabetical letters starting with A, and rows are represented by sequential numbers starting with 1. The address of a cell is determined by writing the column letter followed by the row number. Since the leftmost column is column A and the topmost row is row 1, their intersection at the top-left corner designates the first cell of the worksheet as A1.

Explanation

Vitamin B1 is thiamine, an essential nutrient required for glucose metabolism and nerve function.

Vitamin B2 is riboflavin, which plays a critical role in energy production and cellular function.

The third entry in List I corresponds to pyridoxine, which is the chemical name for vitamin B6.

Vitamin B12 is cyanocobalamin, which is vital for red blood cell formation, neurological function, and DNA synthesis.

Explanation

Ohm's law states that the electric current flowing through a metallic conductor is directly proportional to the potential difference across its ends, provided physical conditions such as temperature and mechanical strain remain constant. This linear relationship is mathematically represented as V = IR, where V is the potential difference, I is the current, and R is the constant of proportionality known as resistance. Metallic conductors obey this relationship over a wide range of voltages, making them classic examples of ohmic devices where Ohm's law is fully valid.

Explanation

Laser stands for Light Amplification by Stimulated Emission of Radiation. A laser beam is characterized by being monochromatic, meaning it consists of light of a single wavelength or a very narrow range of wavelengths, which gives it a single, precise color. Additionally, it is highly coherent, meaning that all the individual light waves emitted are in phase with each other in both space and time, allowing the beam to travel long distances with minimal spreading.

Explanation

The relationship between the Celsius (C) and Fahrenheit (F) temperature scales is given by the formula:

F = (9/5)C + 32

To find the temperature at which both scales are equal, we set C = F = x:

x = (9/5)x + 32

Multiplying the entire equation by 5:

5x = 9x + 160

Rearranging the terms:

-4x = 160

Solving for x:

x = -40

Explanation

Newton's law of gravitation states that the gravitational force F between two masses m₁ and m₂ separated by a distance r is given by:

F = G m₁ m₂ / r²

Rearranging the formula for the universal gravitational constant G:

G = F r² / (m₁ m₂)

The dimensional formulas for the constituent quantities are: Force F = M L T⁻² Distance r = L Mass m = M

Substituting these dimensions into the rearranged formula gives:

[G] = (M L T⁻²) (L²) / (M × M) [G] = M L³ T⁻² / M² [G] = M⁻¹ L³ T⁻²

Explanation

Lemon juice contains a significant amount of citric acid, which constitutes about 5% to 6% of its content, along with ascorbic acid. The pH scale is used to measure the acidity or basicity of an aqueous solution, where a neutral solution has a pH of 7. Acidic solutions have a pH value less than 7, while basic solutions have a pH value greater than 7. Because of the high concentration of hydrogen ions released by these organic acids, lemon juice is highly acidic, typically registering a pH value between 2.0 and 3.0.

Explanation

Furan is a heterocyclic organic compound consisting of a five-membered aromatic ring with four carbon atoms and one oxygen atom. Its chemical formula is C₄H₄O. Heterocyclic compounds are cyclic organic compounds that contain at least one heteroatom, which is an atom other than carbon, such as oxygen, nitrogen, or sulfur, within the ring structure. Because the cyclic ring in furan incorporates an oxygen atom, it is classified as a heterocyclic compound.

Explanation

During electro-refining, the electrolyte contains positively charged metal ions (cations). When an electric current is passed through the electrolytic cell, these metal cations are attracted to the negatively charged electrode, which is the cathode. At the cathode, the metal ions gain electrons (undergo reduction) and are deposited as neutral, pure metal atoms. The general half-reaction at the cathode is:

Mⁿ⁺ + n e⁻ → M

This process ensures that high-purity metal continuously builds up on the cathode, while the impurities either remain in the solution or settle down.

Explanation

Bacteria are microscopic, single-celled organisms that function as decomposers in an ecosystem. They break down complex organic materials from dead plants and animal matter into simpler inorganic nutrients. This decomposition process plays a critical role in nutrient cycling, ensuring that essential elements are returned to the soil, water, and atmosphere to be reused by producers.

Explanation

The term deciduous is derived from the Latin word decidere, which means to fall off. Deciduous trees shed their leaves annually, typically during the autumn season in temperate climates or during the dry season in tropical and subtropical regions. This shedding of leaves is an evolutionary adaptation that helps the trees conserve water and minimize transpiration during periods of cold temperatures or drought. After this period of dormancy, the trees grow new leaves during the next favorable growing season.

Explanation

A hierarchical database model organizes data in a parent-child relationship resembling a tree structure. In this model, a single root node acts as the starting point, branching down into child nodes. Each child node can have only one parent node, while a parent node can have multiple child nodes, establishing a one-to-many relationship that is highly efficient for representing structured, nested information.

Explanation

Natural rubber is a naturally occurring elastomer made of the monomer isoprene, which has the chemical name 2-methylbuta-1,3-diene. Under natural conditions, these monomers undergo addition polymerization to form cis-1,4-polyisoprene. The cis-configuration of the double bonds in the polymer chain prevents the chains from packing closely together, resulting in weak intermolecular forces. This structural arrangement gives natural rubber its highly elastic and flexible properties.

Explanation

Explanation

Sir Winston Churchill was awarded the Nobel Prize in Literature in 1953 for his mastery of historical and biographical description as well as for brilliant oratory in defending exalted human values, rather than the Nobel Peace Prize.

Explanation

The Union Territory of Puducherry consists of four non-contiguous districts: Puducherry, Karaikal, Yanam, and Mahe. These districts are geographically separated from one another by hundreds of kilometers. Puducherry and Karaikal are enclaves surrounded by the state of Tamil Nadu along the Coromandel Coast. Yanam is an enclave situated within the East Godavari district of Andhra Pradesh. Mahe is an enclave located on the Malabar Coast, surrounded by the state of Kerala. Because of this unique geographical distribution, none of the four districts share any common land boundary with one another.

Explanation

Keibul Lamjao National Park is located in the Bishnupur district of Manipur. It is recognized as the only floating national park in the world, characterized by unique floating islands of decomposing organic matter and vegetation known as phumdis. This fragile ecosystem is located on the Loktak Lake, which is the largest freshwater lake in Northeast India, and serves as the last natural habitat for the critically endangered Sangai, or Eld's deer, which is also the state animal of Manipur.

Explanation

World Environment Day is observed globally on June 5 every year to raise awareness and encourage action for the protection of our environment. It was established by the United Nations General Assembly in 1972 during the Stockholm Conference on the Human Environment. Since it is celebrated in June, it is not observed in the month of October.

Explanation

Francisco de Almeida was appointed as the first Governor and Viceroy of Portuguese India in 1505 by King Manuel I of Portugal. He was tasked with establishing Portuguese naval supremacy in the Indian Ocean and securing the spice trade route, a strategy he implemented through the Blue Water Policy, which focused on controlling the seas rather than establishing a vast territorial empire on land.
