    ✓ Correct
  • B.To promote harmony among all people of India
  • C.To safeguard public property
  • D.To uphold and protect the sovereignty of India

Answer & Solution

Correct option is A

The correct answer is (A) To provide opportunities for education to children aged 6–14 years

Explanation:
• The 86th Constitutional Amendment Act of 2002 made a historic change regarding education in India.
• It added the 11th Fundamental Duty to Part IV-A of the Constitution under Article 51A(k).
• This clause states that it is the duty of every citizen who is a parent or guardian to provide opportunities for education to his child or ward between the ages of six and fourteen years.

Information Booster:
• Fundamental Rights Impact: The same 86th amendment also inserted Article 21A, which made the right to free and compulsory education for children aged 6-14 a Fundamental Right.
• DPSP Impact: It altered Article 45 in the Directive Principles of State Policy, shifting its focus to early childhood care and education for children below six years of age.
• Original Duties: The original 10 Fundamental Duties were added in 1976 by the 42nd Amendment on the recommendation of the Swaran Singh Committee.

Additional Knowledge:
• Options B, C, and D: These are all Fundamental Duties, but they were part of the original ten inserted by the 42nd Amendment in 1976, not added in 2002.
Q2.
What is the origin of the material that makes up the Bhabar belt?
  • A.Debris washed down from high ranges
    ✓ Correct
  • B.Weathering of local rocks
  • C.Aeolian deposits
  • D.Glacial deposits

Answer & Solution

Correct option is A

The correct answer is (A) Debris washed down from high ranges

Explanation:
• The Bhabar belt is a narrow region located at the foothills of the Shiwaliks (the outermost range of the Himalayas).
• As fast-flowing Himalayan rivers descend from the steep mountain slopes onto the flat plains, their velocity drops drastically, causing them to deposit heavy loads of coarse debris.
• This material consists mainly of pebbles, gravel, and large boulders. Because of this high porosity, smaller streams disappear underground when they enter the Bhabar belt.

Information Booster:
• Terai Region: South of the Bhabar lies the Terai belt. The streams that disappear in the Bhabar re-emerge here, creating a damp, marshy, and thickly forested region rich in wildlife.
• Agricultural Utility: The Bhabar belt is highly unsuited for agriculture due to its rocky, highly porous soil where surface water cannot be retained.

Additional Knowledge:
• Weathering of local rocks (Option B): Soils like Black cotton soil (Regur) are formed by local weathering (of basalt), but Bhabar is transported alluvium/debris.
• Aeolian deposits (Option C): These are wind-blown deposits, such as loess plains or sand dunes in deserts, not coarse mountain debris.
• Glacial deposits (Option D): These form moraines higher up in the mountains. By the time the material reaches the foothills to form the Bhabar, it is fluvial (river-transported) deposition.
Q3.
Which of the following is a biotic factor causing storage losses in grains?
  • A.Sunlight
  • B.Temperature
  • C.Moisture
  • D.Insects
    ✓ Correct

Answer & Solution

Correct option is D

The correct answer is (D) Insects

Explanation:
• Factors affecting the storage of agricultural produce are broadly classified into two categories: biotic (living) and abiotic (non-living).
• Biotic factors are living organisms that damage the stored grains. These include insects, rodents, birds, mites, and microorganisms like fungi and bacteria.
• Insects are a primary biotic cause of storage loss, as they feed on the endosperm of the grain, rendering it hollow, lightweight, and unfit for human consumption or germination.

Information Booster:
• Damage Caused: These factors cause degradation in quality, loss in weight, poor germinability, and discoloration of produce, ultimately leading to poor marketability.
• Preventive Measures: Proper drying of grains (in sunlight and then in shade), maintaining hygiene in granaries, and the use of fumigants and pesticides help control biotic losses.

Additional Knowledge:
• Options A, B, and C: Sunlight, Temperature, and Moisture are abiotic (non-living) factors. Inappropriate levels of moisture and temperature facilitate the rapid growth of the biotic factors (like fungi and insects) that directly destroy the grain.
Q4.
A farmer wants to improve both the quantity and taste of honey produced on his bee farm. Which of the following strategies should he adopt?
  • A.Reduce the number of beehives and increase the number of bees.
  • B.Move the apiary to an area with fewer flowers.
  • C.Use only local bee varieties for honey production.
  • D.Increase the variety and quantity of flowering plants near the beehives.
    ✓ Correct

Answer & Solution

Correct option is D

The correct answer is (D) Increase the variety and quantity of flowering plants near the beehives.

Explanation:
• Honey is made by bees from the nectar they collect from flowers.
• The quantity of honey produced depends directly on the "pasturage"—the amount and availability of flowering plants accessible to the bees for nectar and pollen collection.
• The taste and quality of the honey are entirely determined by the specific types of flowers (the floral variety) from which the bees gather the nectar. Different flowers yield honey with distinct flavors and aromas.
• Therefore, ensuring a vast and diverse supply of flowering plants (good pasturage) guarantees both high yield and rich, varied taste profiles.

Information Booster:
• Apiculture: The commercial rearing of honey bees is called Apiculture.
• Italian Bee: Often, farmers use the Italian bee variety (Apis mellifera) for commercial production because they have a high honey collection capacity, sting less, and stay in a given beehive for long periods.

Additional Knowledge:
• Reduce hives/Increase bees (Option A): Overcrowding leads to intense competition and swarming, actually reducing overall hive productivity.
• Fewer flowers (Option B): This will starve the bees and drastically lower honey production.
• Local varieties only (Option C): While local bees (Apis cerana indica) are hardy, they yield less honey than exotic varieties like the Italian bee. Taste relies on the flowers, not just the bee breed.
Q5.
Why are crops with different nutrient requirements chosen for inter-cropping?
  • A.To ensure maximum utilisation of nutrients supplied to the field
    ✓ Correct
  • B.To increase the duration of crop growth
  • C.To prevent all pests and diseases completely
  • D.To allow for crop rotation in succession

Answer & Solution

Correct option is A

The correct answer is (A) To ensure maximum utilisation of nutrients supplied to the field

Explanation:
• Inter-cropping is the agricultural practice of growing two or more crops simultaneously in the same field, typically in defined alternating rows.
• The core strategy is to select crops that have completely different nutrient requirements and root architectures (e.g., deep-rooted vs shallow-rooted).
• Because they require different types of nutrients and draw them from different soil depths, they do not compete with each other. This ensures that the soil's resources (and any applied fertilizers) are utilized to their maximum efficiency, resulting in a higher combined yield.

Information Booster:
• Common Pairings: A classic example is intercropping soybean (a legume that fixes nitrogen) with maize (a cereal that demands high nitrogen).
• Disease Control: While it doesn't prevent diseases "completely," intercropping does restrict the rapid spread of pests and diseases, because the alternate rows of a different crop act as physical barriers to species-specific pests.

Additional Knowledge:
• Option B (Increase duration): The goal is higher yield and efficiency, not necessarily altering the intrinsic growth duration of the plants.
• Option C (Prevent completely): No agricultural practice can guarantee the *complete* prevention of pests; it only mitigates the risk.
• Option D (Crop rotation): Crop rotation involves growing different crops sequentially across different seasons, not simultaneously in the same field.
Q6.
Open Market Operations (OMOs) are conducted by RBI to control ____________.
  • A.Money supply
    ✓ Correct
  • B.State budgets
  • C.Corporate profits
  • D.Foreign trade

Answer & Solution

Correct option is A

The correct answer is (A) Money supply

Explanation:
• Open Market Operations (OMOs) refer to the buying and selling of government securities (G-Secs) by the Reserve Bank of India (RBI) in the open market.
• It is a primary quantitative tool of monetary policy used by the central bank to regulate liquidity (money supply) in the economy.
• When the RBI wants to decrease the money supply (during high inflation), it sells government securities to commercial banks, sucking cash out of the system.
• When it wants to increase the money supply (to stimulate growth), it buys back the securities, injecting cash into the banking system.

Information Booster:
• Monetary Policy Tools: OMOs work in tandem with other quantitative instruments like the Repo Rate, Reverse Repo Rate, Cash Reserve Ratio (CRR), and Statutory Liquidity Ratio (SLR).
• Operation Twist: A specialized form of OMO where the RBI simultaneously buys long-term securities and sells short-term securities to manage the yield curve without altering the net liquidity.

Additional Knowledge:
• State budgets (Option B): State budgets are managed by respective state governments; the RBI only acts as a banker to them.
• Corporate profits (Option C): RBI has no direct tool to control private corporate profits.
• Foreign trade (Option D): Managed via EXIM policies, tariffs, and exchange rates, not directly via domestic OMOs.
Q7.
What was a consequence of the economic structure in India between 1947 and 1991?
  • A.High levels of foreign direct investment
  • B.Slow industrial growth due to heavy regulation and protectionism
    ✓ Correct
  • C.Full privatization of the public sector
  • D.Rapid technological advancement in all sectors

Answer & Solution

Correct option is B

The correct answer is (B) Slow industrial growth due to heavy regulation and protectionism

Explanation:
• From independence in 1947 until the economic reforms of 1991, India followed a socialist-inspired economic model characterized by a heavily regulated mixed economy.
• This era was famously termed the License Raj, where establishing or expanding a business required navigating complex bureaucratic hurdles and securing government licenses.
• Protectionist policies, such as high tariffs and import quotas, shielded domestic industries from foreign competition, resulting in monopolies, inefficiencies, and stifled innovation, leading to relatively slow industrial growth (often dubbed the Hindu Rate of Growth).

Information Booster:
• Import Substitution: The core strategy during this period was import substitution industrialization (ISI), aiming to replace foreign imports with domestic production.
• 1991 Economic Reforms: Triggered by a severe balance of payments crisis, the government introduced the LPG reforms (Liberalisation, Privatisation, and Globalisation) under PM P.V. Narasimha Rao and Finance Minister Manmohan Singh.

Additional Knowledge:
• Foreign Direct Investment (Option A): Pre-1991 India actively discouraged foreign investment to protect indigenous industries (e.g., FERA of 1973).
• Privatization (Option C): The public sector was given the commanding heights of the economy; privatization only gained momentum after the 1991 reforms.
• Rapid technological advancement (Option D): The lack of competition and closed economy severely restricted access to global technology.
Q8.
Which of the following islands is the southernmost point of India?
  • A.Kavaratti
  • B.Little Andaman
  • C.Indira Point
    ✓ Correct
  • D.Car Nicobar

Answer & Solution

Correct option is C

The correct answer is (C) Indira Point

Explanation:
• Indira Point, located in the Great Nicobar Island of the Andaman and Nicobar archipelago, is the southernmost point of the Indian territory.
• It is situated at a latitude of 6°45' N.
• The point was formerly known as Pygmalion Point and Parsons Point before being renamed in honor of the former Prime Minister, Indira Gandhi, in the mid-1980s.

Information Booster:
• Mainland Extremity: While Indira Point is the southernmost point of the entire Indian territory, Cape Comorin (Kanyakumari) in Tamil Nadu is the southernmost point of the Indian mainland (8°4' N).
• Tsunami Impact: Indira Point was severely affected and submerged during the 2004 Indian Ocean earthquake and tsunami, though it is slowly emerging again due to geological uplift.
• Other Extremes: The northernmost point is Indira Col (Siachen Glacier), the easternmost is Kibithu (Arunachal Pradesh), and the westernmost is Guhar Moti (Gujarat).

Additional Knowledge:
• Option A (Kavaratti): This is the capital of the Lakshadweep islands, located in the Arabian Sea.
• Option B (Little Andaman): An island in the Andaman archipelago, separated from the Great Andaman by the Duncan Passage.
• Option D (Car Nicobar): The northernmost of the Nicobar Islands, separated from the Andamans by the Ten Degree Channel.
Q9.
What is the origin of the material that makes up the Bhabar belt?
  • A.Debris washed down from high ranges
    ✓ Correct
  • B.Weathering of local rocks
  • C.Aeolian deposits
  • D.Glacial deposits

Answer & Solution

Correct option is A

The correct answer is (A) Debris washed down from high ranges

Explanation:
• The Bhabar belt is a narrow strip of land (about 8-16 km wide) running parallel to the foothills of the Shiwaliks (outer Himalayas).
• Its origin lies in the heavy river action from the mountains. Fast-flowing Himalayan rivers lose their steep gradient as they enter the plains, abruptly losing their carrying capacity.
• As a result, they deposit heavy, coarse loads of pebbles, gravel, and unassorted rock debris carried down from the high ranges, forming the highly porous Bhabar region.

Information Booster:
• Porosity and River Disappearance: The porosity of the Bhabar belt is so high that smaller streams and rivers literally disappear underground as they flow through it.
• Terai Region: South of the Bhabar lies the Terai belt. Here, the underground streams of the Bhabar re-emerge to the surface, creating a damp, marshy, and thickly forested region rich in wildlife.
• Agriculture: Bhabar is unsuitable for agriculture due to its rocky terrain, whereas the Terai, once cleared, is excellent for crops like sugarcane and wheat.

Additional Knowledge:
• Option B (Weathering of local rocks): Bhabar is an alluvial feature made of transported material, not *in situ* weathered rocks.
• Option C (Aeolian deposits): These are wind-blown deposits (like loess or sand dunes), whereas Bhabar is formed by fluvial (river) action.
• Option D (Glacial deposits): Moraines are glacial deposits, found high in the mountains, not at the Himalayan foothills where the Bhabar lies.
