The Sargasso Sea is unique among major seas as it is defined by ocean currents rather than land boundaries. Located in the North Atlantic Ocean, it is surrounded by circulating currents and has no coastline, earning it the nickname 'the sea without a shore.'

The 'new population bomb' refers to the unprecedented rapid urbanization occurring in developing countries. Unlike the original population bomb (total growth), this phenomenon stresses urban infrastructure, housing, and services as megacities grow faster than planning can keep pace.

Carbon dioxide (CO2) is produced during fermentation when yeast converts sugars into alcohol and gas. The CO2 bubbles create the airy, risen texture in bread. This process is called leavening and is essential for making bread light and porous.

Santos—a municipality in the Sao Paulo state of Brazil handles large portion of the world’s Coffee export and thus is also known as Coffee port of world.

Kaziranga National Park in Assam, India, is world-renowned for its population of the one-horned rhinoceros (Rhinoceros unicornis). The park hosts two-thirds of the world's great one-horned rhinoceros population and is a UNESCO World Heritage Site.

Despite the name, 'lead pencils' contain zero percent lead. The core is actually made of graphite (a form of carbon) and clay. The misnomer dates back to the 16th century when graphite was mistaken for a form of lead. Modern pencils use graphite, not lead.

The Mumbai-Pune Expressway, completed in 2002, was India's first six-lane concrete expressway. This 94.5 km highway significantly reduced travel time between Maharashtra's two major cities and set new standards for highway infrastructure in India.

OTCEI (Over The Counter Exchange of India) was an electronic, screen-based stock exchange established in 1992. It was India's first exchange with fully automated trading and aimed to improve transparency and efficiency in share trading, though it later ceased operations.

Lake Victoria forms part of the international boundary between Tanzania and Uganda, and also borders Kenya. As Africa's largest lake by area, it serves as a natural border for these three East African nations and is crucial for their transportation and fisheries.

Vulcanization is the process of hardening rubber by heating it with sulphur. The sulphur forms cross-links between rubber polymer chains, transforming sticky natural rubber into durable, elastic material used for tires, shoes, and various industrial applications. Charles Goodyear discovered this in 1839.

The Gaddi is a semi-nomadic tribe inhabiting the Dhauladhar range of the Himalayas in Himachal Pradesh. Traditionally shepherds, they move their flocks seasonally between high-altitude summer pastures and low-altitude winter grounds. They have a distinct culture and are known for their wool textiles.

Nitrogen (N2) is not a greenhouse gas because its molecular structure is symmetrical and non-polar, so it does not absorb infrared radiation. The other options - carbon dioxide, sulphur dioxide, and ethane - all have molecular structures that trap heat in the atmosphere, contributing to the greenhouse effect.

Helium is used instead of hydrogen because helium is an inert noble gas that does not burn or explode. Hydrogen is highly flammable and poses a catastrophic fire risk, as demonstrated by the Hindenburg disaster. While both gases have low density providing lift, helium's chemical inertness makes it the safer choice for airships.

Lakshadweep islands are coral atolls formed by reef formation over submerged volcanic features. Coral polyps build calcium carbonate structures around volcanic islands, which eventually erode away, leaving ring-shaped reefs and lagoons. This process creates the characteristic atoll formations seen in Lakshadweep.

The gyre of the South Atlantic Ocean is formed by the Brazil Current, the West Wind Drift, and the Benguela Current. The Canaries Current is located in the North Atlantic Ocean, so it does not contribute to the South Atlantic gyre circuit.

The quote 'For fools rush in where angels fear to tread' is from Alexander Pope's poem 'An Essay on Criticism' (1711). Pope uses this line to caution against hasty, uninformed criticism. The line has become a widely-used idiom describing reckless behavior by inexperienced people.

Neil Armstrong spoke the famous words 'That's one small step for [a] man, one giant leap for mankind' as he became the first human to set foot on the Moon during Apollo 11 on July 20, 1969. The 'A' was inaudible in the original radio transmission but is in the written text.

Kutir Jyoti Scheme is a government program providing electricity connections to rural families living below the poverty line. It aims to improve rural quality of life by subsidizing household electrification. The scheme focuses on basic lighting needs rather than industrial or commercial power.

Urea (CO(NH2)2) is a nitrogenous fertilizer containing approximately 46% nitrogen by weight, making it one of the highest nitrogen content fertilizers available. It provides nitrogen in an organic form that plants can convert to usable nitrates. Sodium, phosphatic, and potassium fertilizers provide different nutrients.

National income is the broadest measure of economic development because it captures the total value of goods and services produced. While employment, exports, and consumption are important indicators, they represent only specific aspects. National income reflects overall economic growth and productivity better than any single sectoral measure.

Vinegar is the commercial name for dilute acetic acid solution, typically containing 5-8% acetic acid (CH3COOH) in water. Acetic acid gives vinegar its characteristic sour taste and pungent odor. Oxalic acid and hydrochloric acid are different chemicals with different properties and uses.

CAPART (Council for Advancement of People's Action and Rural Technology) is a government organization that assists and evaluates rural welfare programs. It works to improve rural development initiatives and supports NGOs working in rural areas. The other options are unrelated to CAPART's mission of rural development.

Joseph Lister pioneered antiseptic surgery in the 1860s by introducing carbolic acid (phenol) to sterilize surgical instruments and clean wounds. This dramatically reduced infection rates and mortality from surgery. Lister's work established the principle that microorganisms cause surgical infections and can be killed by antiseptics.

Deflation occurs when the money supply grows more slowly than the supply of goods and services, creating a situation where there is 'too little money chasing too many goods.' This imbalance causes prices to fall as consumers have less purchasing power. The correct answer is option C - lack of money supply compared to supply of goods and services.
