General Knowledge FAQs

Fascism was influenced by German idealist philosophy (Kant, Fichte, Hegel) which emphasized the state and nationalism, combined with Rosenberg's racial theories. The other options represent liberal democratic thought (Aristotle, T.H. Green) or socialist/Marxist ideology.

Washington D.C., the capital of the USA, is situated on the banks of the Potomac River. The Potomac forms part of the border between Maryland and Virginia, and the city was strategically located along this important waterway. The other options - Ohio, Tennessee, and Yukon - are major American rivers but none border the capital city.

Tuticorin (now officially called Thoothukudi) is located on the eastern coast of India in Tamil Nadu, not the western coast. The other options - Nhava Sheva (Jawaharlal Nehru Port) in Maharashtra, Marmagao in Goa, and Kochi in Kerala - are all major ports on India's western coast facing the Arabian Sea.

Marble is a metamorphic rock that forms when limestone is subjected to high heat and pressure over time. This process recrystallizes the calcite in limestone, creating the interlocking crystals that give marble its characteristic appearance.

The Plimsoll Line is a special mark on a ship's hull that indicates the maximum safe loading level. It shows how deep the ship can sit in water without being overloaded, preventing dangerous conditions at sea.

The Bombay High North platform (part of the Mumbai High oil field) did indeed catch fire in July 2005. This was a major accident involving an ONGC offshore oil platform, resulting in casualties and significant damage to India's key offshore oil production facility.

Dialysis works on the principle of osmosis, where solutes move across a semipermeable membrane from an area of higher concentration to lower concentration. In hemodialysis, waste products like urea and excess salts diffuse across the membrane into the dialysate fluid, while larger molecules like proteins are retained in the blood.

The sky appears dark to astronauts because space is essentially a vacuum with very few particles to scatter sunlight. On Earth, the sky appears blue due to Rayleigh scattering of sunlight by atmospheric molecules. Without an atmosphere, there is no scattering, so space looks black even when the sun is shining.

Normal fasting blood sugar levels are typically 80-90 mg/dL (not mg/ml as written - this appears to be a unit error in the question). Post-meal levels can rise to around 140 mg/dL. Levels above 126 mg/dL (fasting) may indicate diabetes. Option C is correct in numerical value despite the unit inconsistency.

Metals are good conductors because they contain free electrons (delocalized electrons) that are not bound to any particular atom. These free electrons can move easily through the metal lattice when an electric field is applied, carrying electrical current efficiently. The other options about molecules being close or colliding are not accurate explanations for metallic conductivity.

A simple microscope consists of a short focus convex lens because shorter focal length provides higher magnification. The convex lens converges light rays from the object, creating a magnified virtual image when the object is placed within the focal length. A concave lens always produces diminished images, and long focal length would give lower magnification.

The correct matching is: Assam-Dispur (3), Dadra & Nagar Haveli-Silvassa (2), Lakshadweep-Kavaratti (4), Sikkim-Gangtok (1). This gives the code (a)3 (b)2 (c)4 (d)1, which matches option B. Dispur is Assam's capital, Silvassa is DNH's capital, Kavaratti is Lakshadweep's capital, and Gangtok is Sikkim's capital.

Copper was the first metal used by humans, dating back to the Chalcolithic period around 8000-5000 BCE. It was widely used before bronze because copper occurs in native (pure) form in nature, can be easily worked, and doesn't require complex smelting. Silver, bronze, and gold came later in human history.

Red light is used for danger signals because it undergoes the least deviation (scattering) when passing through atmospheric particles like dust, fog, and water droplets. According to Rayleigh scattering, longer wavelengths (red) scatter less than shorter wavelengths. This makes red light most visible over long distances and in poor visibility conditions.

Scurvy, caused by Vitamin C deficiency, leads to weakened collagen production. This affects connective tissues in gums, causing bleeding and loosening of teeth. Vitamins A, B, and D are not directly related to these symptoms.

Oil spreads on water because water's high surface tension creates a strong 'skin' effect. Oil has much lower surface tension, allowing it to form a thin film across the water surface. Density (option A) and viscosity (option B) are secondary factors.

A rectifier uses diodes to convert alternating current (AC) to direct current (DC) by allowing current flow in only one direction. Oscillators generate AC signals, amplifiers increase signal amplitude, and neither performs conversion.

The Ashoka Chakra (Dharma Chakra) at the center of the Indian flag is navy blue. It represents the eternal wheel of law and dharma. The flag uses three colors: saffron, white, and green, with the chakra in navy blue at the center.

Jean-Baptiste Travernier, a French jeweler, visited India during Shah Jahan's reign and documented the Peacock Throne's magnificence in his travels. His detailed description provides historical insight into Mughal luxury and craftsmanship.

The International Court of Justice (ICJ), the principal judicial organ of the UN, is located at The Peace Palace in The Hague, Netherlands. It settles disputes between states and gives advisory opinions.

The Latin term 'homo sapiens' literally translates to 'wise man' or 'man the wise,' distinguishing humans by their cognitive capabilities. This reflects the defining characteristic of human intelligence and reasoning ability.

A writ of mandamus is a court order compelling a government official or public authority to perform a mandatory duty correctly. It cannot be used to direct policy decisions (like dissolving cabinets) or private matters (company wages).

Gresham's Law states that 'bad money drives out good' - when two forms of money with the same face value but different intrinsic values circulate together, people hoard the valuable money and spend the debased money. This is about circulation dynamics, not consumption or supply-demand.

The Munabao (India) - Khokhrapar (Pakistan) rail link was established as a Confidence Building Measure (CBM) under the Indo-Pak peace initiative. It reconnects the historical Thar Express route, facilitating people-to-people contact and trade.

Hargobind Khorana, born in India, shared the 1968 Nobel Prize in Physiology or Medicine for cracking the genetic code and protein synthesis. Raja Ramanna was a nuclear physicist, C.V. Raman won the Physics Nobel (1930), and Jagadish Chandra Bose was a polymath scientist.

Indica, written by the Greek ambassador Megasthenes during the Mauryan period (c. 300 BCE), is the first known Western account of India. It documented Indian society, geography, and culture under Chandragupta Maurya.

Nicholas Kaldor proposed the expenditure tax in the 1950s as an alternative to income taxation. The idea was to tax consumption rather than income, which could encourage saving and reduce economic inequality. This approach differs from traditional income taxes by focusing on what people spend rather than what they earn.

Laissez-faire is an economic philosophy advocating minimal government interference in market transactions. The term translates to 'let do' in French, meaning allowing demand and supply forces to operate freely without regulation. This contrasts with planned economies where governments control production and pricing decisions.

Bank rate is the rate at which a central bank rediscounts first-class securities like bills of exchange and commercial paper presented by commercial banks. It's a monetary policy tool used to control money supply and credit conditions in the economy. When central banks raise this rate, borrowing becomes more expensive, reducing liquidity.

Charak (Charaka) was the renowned court physician of the Kushan emperor Kanishka during the 1st-2nd century CE. He authored the Charaka Samhita, a foundational text of Ayurveda that covers medicine, surgery, and pharmacology. This work remains one of the principal classical texts on ancient Indian medicine.

Balance of Payments (BoP) is a comprehensive record of all economic transactions between residents of a country and the rest of the world during a given period. It includes trade balance, services, income transfers, and capital flows. Unlike Balance of Trade which only covers goods, BoP encompasses all monetary transactions including invisible items.

Mrs. Annie Besant founded the Home Rule League in Calcutta in 1916 as part of India's independence movement. The league advocated for self-rule within the British Empire through constitutional means. While the movement had branches across India, the Calcutta branch specifically was established under her leadership.

The Axis powers in World War II were Germany, Italy, and Japan, who signed the Tripartite Pact in 1940. This military alliance opposed the Allied powers (Britain, USA, USSR, and others). The three nations coordinated their military and political strategies to expand their territories and influence globally during the war.

Pensions are included in National Income calculations as they represent transfer payments from one section of society to another. While transfer payments don't create new goods or services, they are part of the national income accounting system. Services of housewives, smugglers' income, and watchmen's income are excluded for various reasons - some being non-market activities or illegal.

Babar, the founder of the Mughal Empire, specifically requested to be buried in Kabul rather than India. His garden-tomb in Kabul remains his resting place, reflecting his deep connection to the region despite establishing rule in India. Kabul held personal significance for Babar as his ancestral home and power base before the Indian conquest.

The Government of India Act 1919 is known as the Montagu-Chelmsford Reforms, named after Secretary of State Edwin Montagu and Viceroy Lord Chelmsford. It introduced the dyarchy system where certain subjects were transferred to Indian ministers while others remained with British officials. This was a significant step toward responsible government in colonial India.

During photosynthesis, plants release oxygen as a byproduct of the light-dependent reactions. When chlorophyll absorbs light energy, water molecules are split (photolysis) in the thylakoid membranes, releasing oxygen as a waste product. This oxygen comes from water, not from carbon dioxide, which is used in the subsequent Calvin cycle to produce glucose.

A.O. Hume, a British civil servant, founded the Indian National Congress in 1885. He is widely regarded as the 'Father of the Indian National Congress' for his role in its formation. While leaders like Gandhi and Tilak became prominent later, Hume was the founding architect.

A knot is a unit of speed equal to one nautical mile per hour. It is primarily used in maritime and aviation contexts to measure the speed of ships and aircraft. 1 knot equals approximately 1.15 miles per hour or 1.85 kilometers per hour.

Tar gas is commonly known as nitrous oxide (N2O), also called laughing gas. Historically, nitrous oxide was sometimes obtained from the distillation of coal tar or similar organic materials. The term 'tar gas' refers to this association with tar distillation processes.

Agronomy is the branch of agriculture that deals with the study of field crops and soil management. Pomology is the study of fruits, olericulture deals with vegetables, and floriculture focuses on flowering plants. Agronomy specifically addresses crops grown in large fields like wheat, rice, corn, etc.

Parthenogenesis is the development of an embryo from an unfertilized egg. It occurs naturally in some species like bees, ants, and aphids. Gametogenesis is the formation of gametes, oogenesis is egg formation, and metamorphosis is the transformation process in organisms.

Carrots contain carotene, specifically beta-carotene, which is a pigment responsible for their orange color. Beta-carotene is also a precursor to vitamin A in the human body. The color is due to this chemical pigment, not soil conditions or sunlight exposure.

In biological context, a vector is an organism that transmits disease-causing pathogens from one host to another. Insects like mosquitoes, fleas, and ticks are common vectors. The other terms like transmitter, drones, or conductor are not standard scientific terminology for disease transmission.

Samuel Hahnemann, a German physician, founded homeopathy in the late 18th century. He developed the principle of 'like cures like' that forms the basis of homeopathic treatment. Hippocrates is the 'Father of Medicine,' while Charaka and Sushrutha are ancient Indian medical practitioners.

Streptomycin is an antibiotic effective against tuberculosis, discovered by Selman Waksman in 1943. Penicillin is not effective against TB. Chloromycetin (chloramphenicol) treats bacterial infections but not TB. Terramycin (oxytetracycline) is also ineffective against tuberculosis.

Algae and blue-green algae (cyanobacteria) are biofertilizers as they fix atmospheric nitrogen and enrich soil fertility. Compost and cattle dung are organic manures, not biofertilizers. Ammonium sulphate is a chemical fertilizer. Biofertilizers are living microorganisms that enhance nutrient availability.

Oxalic acid solution is used to remove rust (iron oxide) stains from cloth. Oxalic acid reacts with iron oxide to form soluble compounds that can be washed away. Kerosene, lime, or petrol are not effective for rust stain removal - they work on different types of stains.

ICC headquarters moved from London (Lords) to Dubai on August 1, 2005, relocating from its traditional home in the UK to a more central global location. Sydney, Melbourne, and Jamaica were never considered as ICC headquarters.

SARS stands for Severe Acute Respiratory Syndrome, a viral respiratory illness caused by the SARS-associated coronavirus. The term accurately describes the condition - it's severe (serious), acute (sudden onset), affects the respiratory system, and is a syndrome (collection of symptoms).

Ho Chi Minh led the Vietnamese independence movement against French colonial rule, eventually becoming President of North Vietnam. Ngo Dinh Diem was a South Vietnamese leader, Zhou Enlai was Chinese, and Pol Pot was Cambodian.

Putting is a stroke in golf where the ball is rolled along the ground toward the hole using a putter. Hockey uses 'pushing' or 'drag flick,' chess has no equivalent term, and billiards uses various stroke techniques but not 'putting'.

Ashtangika Marg (Eightfold Path) was propounded by Gautam Buddha as the path to eliminate human suffering (dukkha). It consists of right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness, and right concentration. Mahavira founded Jainism, Adi Shankaracharya was a Hindu philosopher, and Kabir was a mystic poet.

The '7/7' terrorist attacks refers to the coordinated suicide bombings in London on July 7, 2005, targeting the Underground (subway) and buses. 9/11 was the World Trade Center attack in New York, Ayodhya was the Ram temple incident, and Madrid had a separate rail bombing (3/11/2004).

Platelets (thrombocytes) are the blood components responsible for clotting - they gather at wound sites, release clotting factors, and form platelet plugs. RBCs carry oxygen, lymphocytes are white blood cells for immunity, and monocytes are also white blood cells that fight infection but don't directly clot blood.

Pakistan celebrates Independence Day on August 14, 1947, one day before India's independence (August 15, 1947). July 4 is American Independence Day, and August 16 has no particular significance for Pakistan's independence.

NIFTY is the flagship stock market index of the National Stock Exchange (NSE) of India, comprising 50 major companies. It's not related to cloth markets (sensex/saree confusion), consumer prices (CPI), or BSE (which uses Sensex index).

Penalty stroke is a hockey term, not football. In football, similar concepts are 'penalty kick' or just 'penalty.' Football uses penalty kicks, free kicks, and off-side rules, but penalty stroke belongs to hockey.

In 2003, China officially recognized Sikkim as part of India, ending a long-standing border dispute. This was significant because Sikkim had been a protectorate and then became India's 22nd state. China previously had territorial claims, but this recognition resolved the issue.

INS Vikrant (earlier INS Virat) is a Centaur-class aircraft carrier that served as the flagship of the Indian Navy. Aircraft carriers are large warships designed to carry and deploy fighter aircraft, serving as mobile airbases at sea. Submarines operate underwater, gunboats are small armed vessels, and freighters are cargo ships - none of which describe a carrier's role.

The Illegal Migrants (Determination by Tribunal) Act, 1983 was struck down by the Supreme Court in 2005 (Sarbananda Sonowal case). It specifically applied to Assam and dealt with identifying illegal migrants from Bangladesh, not Nepal or Bhutan. The IMDT Act placed the burden of proof on the accuser rather than the accused, which the Court found unconstitutional.

At high altitudes, atmospheric pressure decreases significantly while blood pressure remains relatively constant. This pressure differential causes blood vessels in the nose (which are delicate and close to the surface) to rupture, resulting in nosebleeds. The external pressure drops more than internal blood pressure adjusts, creating outward pressure on capillary walls.

According to Article 61 of the Indian Constitution, when both President and Vice President offices are vacant, the Chief Justice of India (or the senior-most Supreme Court judge available) discharges the President's functions. This constitutional provision ensures continuity of the highest office. The Prime Minister and Home Minister do not have this constitutional authority, and the Speaker presides over Lok Sabha, not the executive.

Aryabhatta (5th century CE) is credited with using zero as a number in Indian mathematics, though Brahmagupta later formalized its operations. However, the concept evolved over centuries - Babylonians used zero as a placeholder earlier. Within the Indian context of this question's options, Aryabhatta is the intended answer. Ramanujam is modern (20th century), Patanjali is known for Yoga sutras.

Viscose (a type of rayon) was historically used for parachutes due to its strength, elasticity, and resistance to moisture. While modern parachutes use nylon, viscose-rayon fabrics were standard in early parachuting. Terylene is polyester, cotton is natural fiber, and rayon is the broader category.

Thorium is a naturally radioactive element (atomic number 90) found in monazite sands. All thorium isotopes are radioactive, with Th-232 being the most abundant. While cesium, strontium, and platinum can have radioactive isotopes, they are not inherently radioactive in their natural form. Strontium-90 and Cesium-137 are fission products, not naturally occurring.

Sania Mirza, the renowned Indian tennis player, was appointed as the Goodwill Ambassador for the 'Save the Girl Child' campaign (Beti Bachao Beti Padhao) by the Union Ministry of Health and Family Welfare. Her high profile made her an effective advocate for this cause. The other sportspersons listed were not associated with this specific campaign.

ECOMARC is an Indian ecolabel certification mark that indicates products are environmentally safe throughout their lifecycle - from production to disposal. It certifies that goods meet specific environmental standards, not their quality or export/import status. The mark helps consumers identify eco-friendly products.

Milk is an emulsion - a colloid where liquid fat droplets are dispersed in water-based fluid. Casein proteins act as natural emulsifiers, keeping fat from separating. It's not a solution (homogeneous mixture), simple mixture (components don't settle), or suspension (particles would settle over time). Emulsions are specifically liquid-in-liquid colloidal dispersions.

Wind deposition creates sand dunes when wind carries sand particles and deposits them in piles. Wind erosion removes material but does not build up dunes. Water erosion and mechanical weathering are not responsible for dune formation in arid regions like Rajasthan.

Insolation is the specific technical term for incoming solar radiation reaching Earth's surface. Radiant energy is too generic and could refer to any electromagnetic radiation. Sunshine is an informal term. Terrestrial radiation refers to heat radiation emitted by Earth itself, not incoming solar energy.

Vitamin A deficiency causes poor eyesight (especially night blindness). Iron deficiency causes anaemia (reduced hemoglobin). Vitamin C deficiency causes skin problems like scurvy and bleeding gums. Calcium deficiency causes weak bones that fracture easily. Option C correctly matches all pairs.

Boyle's Law states that for a fixed amount of gas at constant temperature, pressure is inversely proportional to volume (P1V1 = P2V2). Volume and temperature relationship is Charles's Law. Volume and density are not directly related by Boyle's Law. Pressure and temperature relationship is Gay-Lussac's Law.

Central taxes in India include Income Tax, Customs Duty, and Excise Duty (now GST subsumes excise). Sales tax is a state tax. House tax is a municipal/local tax. Entertainment tax varies by state. Option B correctly lists three central taxes.

The term 'Fourth Estate' refers to the press and media, watchdogs that monitor the three branches of government (Legislature, Executive, Judiciary). The media plays a crucial role in democracy by informing the public and holding power accountable. It is not part of the formal government structure.

The UN Security Council has 15 total members: 5 permanent members (US, UK, France, Russia, China) with veto power, and 10 non-permanent members elected for 2-year terms. Option A correctly states this composition. The other options incorrectly reverse the numbers or omit one category.

The main switch disconnects only the live (phase) wire to cut off power supply. The neutral wire remains connected to ground. The earth wire is a safety connection and is also not disconnected by the main switch. This prevents current flow while maintaining safety grounding.

In a Joint Parliamentary Session of India's Parliament, the Speaker of the Lok Sabha presides and casts the deciding vote in case of a tie. The Chairman of Rajya Sabha does not preside over joint sessions. The Deputy Speaker and Prime Minister do not have this constitutional role.

Rajya Sabha members are allocated based on each state's population, ensuring proportional representation. Larger states have more seats. It is not based on area, Lok Sabha strength, or fixed numbers. This population-based allocation is specified in the Constitution's Fourth Schedule.

Solar heat reaches Earth primarily through radiation across the vacuum of space. Minor conduction occurs in the atmosphere, and atmospheric convection currents distribute heat. Since all three processes contribute to varying degrees, Option D is technically correct. Radiation is the dominant mechanism.

The President of India is elected by an Electoral College comprising elected members of both Houses of Parliament (Lok Sabha and Rajya Sabha) and State Legislative Assemblies. Nominated members to either House of Parliament or State Legislatures are not part of this Electoral College. The election is conducted by the Election Commission using proportional representation.

Bandipur National Park is located in Karnataka, Gir National Park in Gujarat (famous for Asiatic lions), and Manas Sanctuary in Assam. The matching pattern (4-1-2) corresponds to option C. The fourth entry 'Rohla National Park' appears to be a typographical error.

The Basic Structure doctrine was established by the Supreme Court in Kesavananda Bharati v. State of Kerala (1973). This landmark judgment held that while Parliament has wide powers to amend the Constitution, it cannot alter its basic features. Golak Nath (1967) earlier held that fundamental rights cannot be amended, but this was overruled by Kesavananda Bharati.

The International Development Association (IDA) is the 'soft loan window' of the World Bank Group. It provides concessional loans and grants to the world's poorest countries. IDA loans have zero or very low interest rates and long repayment periods. IFC lends to private sector, IMF is a separate institution for monetary cooperation.

Fragmentation of landholdings occurs primarily due to the law of inheritance (land divided among heirs) and the cultural desire for land ownership. Consolidation (2) actually increases average holding size by merging small plots. Farm mechanization (3) can encourage consolidation to make machines economically viable, rather than reducing holdings.
