Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (B) Ti

Explanation

Titanium is extensively used in the aerospace and spacecraft industries because it possesses an exceptional strength-to-weight ratio, being as strong as steel but nearly 45 percent lighter. It has a high melting point of approximately 1668 degrees Celsius and retains its structural integrity and mechanical properties at significantly elevated temperatures. This thermal stability is critical for spacecraft components that experience intense heat during atmospheric exit and reentry, as well as for structural elements exposed to solar radiation in vacuum conditions. Furthermore, titanium exhibits low thermal expansion and high resistance to corrosion, ensuring the durability and reliability of the vessel in extreme environments.

Show answer & explanationHide answer

Answer: (A) Garett Hardin

Explanation

Garrett Hardin, an American ecologist and philosopher, propounded the modern concept of the Tragedy of the Commons in his 1968 article published in the journal Science. He described a situation where individuals acting independently and rationally according to their own self-interest behave contrary to the common good of all users by depleting or spoiling a shared resource through their collective action. Using the analogy of a common pasture, Hardin argued that each herdsman seeks to maximize his gain by adding more cattle, but since the benefits are individual while the costs of overgrazing are shared, the resource is inevitably over-exploited. His work provided a foundational framework for environmental economics and resource management, emphasizing that without social arrangements, private property, or government regulation, shared resources are prone to collapse.

Answer: (A) Daocheng Yading Airport

Explanation

Daocheng Yading Airport, located in the Garzi Tibetan Autonomous Prefecture of Sichuan Province, China, is situated at an elevation of 4411 meters (14472 feet) above sea level. Upon its opening in September 2013, it officially became the highest civilian airport in the world, surpassing the Qamdo Bamda Airport. The high altitude requires a long runway, measuring 4200 meters, to compensate for the reduced engine performance and lift caused by the thinner air at such elevations. This infrastructure project was a significant engineering feat aimed at improving access to the Yading Nature Reserve and the surrounding Tibetan Plateau region.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (B) Hydrogen sulphide

Explanation

Brass is an alloy primarily composed of copper and zinc. When brass is exposed to the atmosphere, it reacts with hydrogen sulphide (H₂S) gas, which is often present in the air in trace amounts. This chemical reaction results in the formation of a layer of copper sulphide (Cu₂S) and zinc sulphide (ZnS) on the surface of the metal. These sulphide products are dark in color, leading to the tarnishing and discoloration of the brass object over time.

For the following questions answer them individually A NOT gate can be implemented by:
Tap an option to check yourself

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (D) single transistor

Explanation

A NOT gate, also known as an inverter, is implemented using a single transistor configured in common-emitter mode, which is the basic building block of Resistor-Transistor Logic (RTL). In this circuit, the input signal is fed to the base of an NPN transistor. When the input is at a low voltage level (logic 0), the transistor is in the cutoff region and acts as an open switch. This prevents current from flowing through the collector-emitter path, causing the output voltage at the collector to be pulled up to the supply voltage V_C_C (logic 1) through a load resistor. When the input is at a high voltage level (logic 1), the transistor is driven into saturation and acts as a closed switch. This creates a path to ground, causing the output voltage at the collector to drop to approximately zero volts (logic 0). This relationship where a low input produces a high output and a high input produces a low output defines the fundamental operation of the NOT gate.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (A) Union of States

Explanation

Article 1(1) of the Constitution of India explicitly states that India, that is Bharat, shall be a Union of States. This nomenclature was preferred by the Drafting Committee, led by Dr. B.R. Ambedkar, to emphasize two critical points: first, that the Indian federation is not the result of an agreement among sovereign states, unlike the American federation; and second, that the constituent states have no right to secede from the federation. The term Union signifies that the country is an integral whole, divided into different states only for the convenience of administration, while maintaining an indestructible character.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (D) Afforestation

Explanation

Afforestation is the process of establishing a forest or stand of trees in an area where there was no previous tree cover. It is a primary method for soil conservation on a massive scale because the extensive root systems of the trees bind soil particles together, significantly increasing the ground's stability and resistance to erosion by wind and water. Furthermore, the tree canopy acts as a protective shield that intercepts falling rain, reducing the impact of water droplets on the soil surface and decreasing the volume of surface runoff. Over time, the accumulation of leaf litter from these plantations adds organic matter to the soil, improving its structure and water-retention capacity.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (B) Cinema

Explanation

Persistence of vision is the physiological phenomenon where the human eye retains an image for a brief duration, approximately 1/16th of a second, after the object is no longer visible. Cinema utilizes this principle by projecting a sequence of static images on a screen at a rapid rate, typically 24 frames per second. Because the interval between the frames is shorter than the duration of the persistence of vision, the brain blends the individual images together. This creates a seamless illusion of continuous motion rather than a series of flickering still photographs.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (C) 2.5

Explanation

Particulate Matter 2.5 (PM 2.5) refers to fine inhalable particles with a diameter of 2.5 micrometers or less. These particles are particularly hazardous to human health because their extremely small size allows them to bypass the protective filters of the upper respiratory system. Once inhaled, PM 2.5 can penetrate deep into the lungs, reaching the alveolar region, and even enter the bloodstream. This systemic entry enables the particles to cause widespread inflammation and oxidative stress, leading to the deterioration of vital body organs. Long-term exposure is linked to serious health conditions, including chronic respiratory diseases, heart attacks, and impaired lung function.

Show answer & explanationHide answer

Answer: (C) Plants

Explanation

Primary producers, also known as autotrophs, are organisms that can synthesize their own food from inorganic substances using light or chemical energy. In most terrestrial and aquatic ecosystems, green plants serve as the primary producers by performing photosynthesis. During this process, plants use chlorophyll to capture solar energy and convert water and carbon dioxide into organic compounds like glucose, which store chemical energy. Because they create the initial biomass that supports all other trophic levels, plants form the fundamental base of the food chain, providing energy for herbivores and subsequently for carnivores and decomposers.

Show answer & explanationHide answer

Answer: (D) Not a member of the Parliament

Explanation

According to Article 66(2) of the Constitution of India, the Vice-President shall not be a member of either House of Parliament or of a House of the Legislature of any State. If a member of any such House is elected Vice-President, they are deemed to have vacated their seat in that House on the date they enter upon the office. Although Article 64 stipulates that the Vice-President is the ex-officio Chairman of the Rajya Sabha, this is a functional role attached to the office rather than a status of membership. Because the Vice-President is not a member of the House, they do not have the right to vote in the first instance during parliamentary proceedings, holding only a casting vote to resolve a tie.

Tap an option to check yourself

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (A) Maida and Yeast

Explanation

Bread making fundamentally requires a base flour and a leavening agent to achieve its characteristic structure and texture. Maida, or refined wheat flour, is used as the primary ingredient because it contains high levels of gluten-forming proteins that create an elastic network capable of trapping gases. Yeast serves as the essential biological leavening agent; through the process of fermentation, it converts sugars into carbon dioxide gas and ethanol. This gas becomes trapped within the gluten matrix, causing the dough to rise and resulting in a light, porous finished product after baking.

Tap an option to check yourself

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (A) Adrenaline

Explanation

Adrenaline, also known as epinephrine, is secreted by the adrenal medulla in response to stress, danger, or excitement. It is famously termed the emergency hormone because it initiates the fight-or-flight response, preparing the body to either confront a threat or flee from it. Upon release into the bloodstream, adrenaline rapidly increases the heart rate, elevates blood pressure, dilates air passages in the lungs, and stimulates the liver to convert glycogen into glucose for an immediate energy boost. These physiological changes ensure that muscles and the brain receive a surge of oxygen and fuel to handle high-pressure situations effectively.

Show answer & explanationHide answer

Answer: (C) Anopheles Mosquito

Explanation

Malaria is a parasitic disease caused by Plasmodium species, which are transmitted to humans through the bite of an infected female Anopheles mosquito. This mosquito serves as the definitive host and biological vector in the parasite's life cycle. When the mosquito bites an infected person, it ingests the parasite, which then undergoes a period of development within the mosquito. Once the parasite reaches the infectious sporozoite stage, it migrates to the mosquito's salivary glands and is injected into a new human host during a subsequent blood meal.

Show answer & explanationHide answer

Answer: (D) proteins

Explanation

Liver is an exceptionally nutrient-dense organ that serves as a primary site for protein synthesis in the body. It produces essential plasma proteins such as albumin, globulins, and various coagulation factors. On a per-gram basis, liver contains approximately 20 to 29 percent protein, providing a complete profile of all nine essential amino acids. This high protein density is due to the concentration of hepatocytes and the vast array of metabolic enzymes required for the organ's diverse biochemical functions. The protein found in liver is highly bioavailable, making it an efficient dietary source for supporting tissue growth, repair, and the production of endogenous proteins.

Show answer & explanationHide answer

Answer: (D) Parasite

Explanation

Cuscuta is an obligate stem parasite that lacks chlorophyll and functional leaves, rendering it incapable of performing photosynthesis. To survive, it attaches itself to a host plant using specialized adventitious roots known as haustoria. These structures penetrate the host plant's epidermis and reach the vascular bundles, specifically the xylem and phloem, to extract water, minerals, and carbohydrates. Because it derives all its nutritional requirements from the host tissue while potentially harming the host, it is biologically classified as a parasite.

Tap an option to check yourself

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (B) Negative

Explanation

Income elasticity of demand measures the responsiveness of the quantity demanded of a good to a change in the income of consumers. In the case of inferior goods, there is an inverse relationship between income and demand. As a consumer's income increases, they tend to switch their consumption from lower-quality or cheaper substitutes to higher-quality superior goods, leading to a decrease in the quantity demanded of the inferior good. Mathematically, the income elasticity of demand is calculated as the percentage change in quantity demanded divided by the percentage change in income. Since these two variables move in opposite directions for inferior goods, the resulting coefficient is always less than zero, or negative.

Show answer & explanationHide answer

Answer: (B) Proteins

Explanation

Proteins are large biomolecules comprised of one or more long chains of amino acid residues. The fundamental structure of an amino acid consists of a central carbon atom bonded to a hydrogen atom, a carboxyl group (-COOH), a side chain (R group), and an amino group (-NH₂). Since the amino group, which contains nitrogen, is a constant and defining part of every amino acid, nitrogen is an essential constituent of all proteins. These molecules play critical roles in the body, including acting as enzymes, structural components, and signaling molecules, all of which depend on the nitrogen-based chemical architecture of their constituent amino acids.

Answer: (A) Atlantic Ocean

Explanation

The Sargasso Sea is located in the North Atlantic Ocean and is uniquely characterized as the only sea on Earth that has no land boundaries. It is defined by four major ocean currents that form the North Atlantic Gyre: the Gulf Stream to the west, the North Atlantic Current to the north, the Canary Current to the east, and the North Atlantic Equatorial Current to the south. These circulating currents trap a large body of relatively calm, warm water in the center of the gyre. The sea is named after the genus Sargassum, a type of free-floating brown seaweed that accumulates on the surface of the water, providing a rich habitat for various marine species. It is situated between roughly 20 to 35 degrees North latitude and 40 to 70 degrees West longitude.

Show answer & explanationHide answer

Answer: (C) Maxwell

Explanation

James Clerk Maxwell formulated the classical theory of electromagnetic radiation, which unified electricity, magnetism, and light as different manifestations of the same physical phenomenon. In his 1865 work, A Dynamical Theory of the Electromagnetic Field, he developed a set of equations showing that changing electric and magnetic fields propagate through space as transverse waves. By using the electromagnetic constants for the permittivity of free space ₀ and the permeability of free space ₀, he calculated the theoretical speed of these waves using the relation c = (1)/(√(₀ ₀)). Because the resulting value was approximately 3 × 10⁸ meters per second, which matched the experimentally measured speed of light, Maxwell concluded that light is an electromagnetic wave.

Answer: (B) Gandhi and Ambedkar

Explanation

The Poona Pact of 1932 was a historic agreement between Mahatma Gandhi and Dr. B.R. Ambedkar regarding the representation of the Depressed Classes in the legislature of British India. The pact was signed on September 24, 1932, at Yerwada Central Jail in Poona. It served as a resolution to the crisis created by the British government's Communal Award, which had granted separate electorates to the Depressed Classes. Gandhi opposed this move, believing it would permanently divide Hindu society, and commenced a fast unto death in protest. The agreement facilitated the withdrawal of separate electorates in exchange for a significantly higher number of reserved seats for the Depressed Classes in provincial and central legislatures, to be filled through a system of joint electorates.

Tap an option to check yourself

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (A) brightness of the object

Explanation

In photography, the total exposure H received by the sensor or film is defined by the product of the illuminance E and the exposure time t, expressed by the relation H = E × t. The illuminance E reaching the camera is directly proportional to the luminance or brightness of the object being photographed. For a fixed aperture and sensitivity, the time of exposure must be adjusted in inverse proportion to the brightness of the object to maintain a constant, optimal exposure H. An object with high brightness reflects a large number of photons per second, requiring a shorter shutter speed to prevent overexposure. Conversely, a dull or dimly lit object requires a longer exposure time to gather sufficient light to form a clear and discernible image.

Answer: (D) with United Kingdom against Germany

Explanation

Japan joined World War I as a member of the Allied Powers, primarily motivated by the Anglo-Japanese Alliance of 1902. This strategic treaty with Great Britain aimed to protect their respective interests in East Asia. Following the outbreak of the war, Japan issued an ultimatum to the German Empire and officially declared war on August 23, 1914. During the conflict, Japanese forces captured the German-leased territory of Tsingtao in China and seized German colonial possessions in the North Pacific, including the Marshall, Caroline, and Mariana Islands. Additionally, the Imperial Japanese Navy provided crucial support to the British by escorting Allied convoys in the Mediterranean and patrolling the Pacific and Indian Oceans to secure shipping lanes against German commerce raiders.

Answer: (B) Barack Obama

Explanation

The term Rainbow Coalition in modern political discourse is associated with Barack Obama's electoral strategy and his broad-based policy appeals. During the 2008 and 2012 US Presidential elections, Obama successfully assembled a diverse demographic alliance consisting of African Americans, Hispanics, young voters, and college-educated whites. This multicultural and multiracial coalition was essential for his victories and was widely analyzed by political commentators as a modern manifestation of a rainbow coalition. His policies and rhetoric focused on inclusivity and bridging racial and social divides, which solidified his connection to this diverse group of supporters.

Show answer & explanationHide answer

Answer: (A) Ionosphere

Explanation

The ionosphere is a region of the upper atmosphere, extending from approximately 60 km to 1,000 km, characterized by a high concentration of ions and free electrons. These particles are created through the ionization of atmospheric gases by solar ultraviolet and X-ray radiation. When radio waves in the high-frequency or short-wave spectrum are transmitted from Earth, they interact with these free electrons. The resulting change in the refractive index causes the waves to bend or refract so significantly that they are directed back toward the Earth's surface. This phenomenon, known as skywave propagation, enables long-distance radio communication across the globe by allowing signals to bypass the curvature of the Earth.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (B) Parliament

Explanation

The Fundamental Rights guaranteed by the Indian Constitution are not absolute and are subject to reasonable restrictions to ensure a balance between individual liberty and social control. Under various clauses of Article 19 and other relevant provisions, the Parliament is empowered to impose these restrictions by enacting laws. Such restrictions must be based on specific grounds mentioned in the Constitution, such as the sovereignty and integrity of India, security of the state, friendly relations with foreign states, public order, decency, or morality. While the Parliament has the authority to legislate these limitations, the judiciary retains the power of judicial review to determine whether the restrictions imposed by the legislative body are indeed reasonable and constitutional.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (C) 1

Explanation

In the human female reproductive system, the menstrual cycle involves the maturation of several follicles within the ovaries under the influence of Follicle-Stimulating Hormone (FSH). As the cycle progresses, one follicle usually outpaces the others to become the dominant Graafian follicle, while the remaining follicles undergo a process of degeneration known as atresia. Approximately mid-cycle, a surge in Luteinizing Hormone (LH) triggers ovulation, causing this single dominant follicle to rupture. This release sends one mature egg, or secondary oocyte, into the fallopian tube where it may encounter sperm for fertilization. This physiological regulation ensures that, under normal circumstances, only one egg is available for fertilization during each cycle.

Show answer & explanationHide answer

Answer: (D) Camel

Explanation

Camels possess unique physiological and genetic adaptations that allow them to consume high levels of salt without developing hypertension. Living in arid desert environments, they often feed on halophytic plants and drink brackish water containing salt concentrations that would be toxic to most other mammals. Their kidneys are highly efficient at concentrating urine and excreting excess salt while conserving water. Research indicates that camels have specific evolutionary changes in their genes related to salt metabolism and blood pressure regulation, enabling them to maintain stable cardiovascular health despite a diet that provides roughly eight times the salt intake of other ruminants.
