Previous Year UPSC Questions

Explanation

Option (b) is correct: Joseph François Dupleix, the French Governor-General in India, was the first European to actively involve himself in the disputes and power struggles of Indian rulers. Dupleix actively pursued a policy of interference in local Indian disputes, particularly during the Carnatic Wars (1746-1763) and the succession conflicts in Hyderabad. He supported rival claimants and used French military power to influence Indian politics. In the First Carnatic War (1746-1748), Dupleix allied with Chanda Sahib against Anwar-ud-Din, the Nawab of Arcot, to strengthen French influence in the region. During the Second Carnatic War (1749-1754), he backed Muzaffar Jung for the throne of Hyderabad and Chanda Sahib for the Nawabship of Arcot, aiming to expand French control in South India. Options (a), (c) and (d) are incorrect:

Robert Clive, known for expanding British rule in India, adopted similar strategies to Dupleix, especially after the Battle of Plassey (1757). Afonso de Albuquerque, a Portuguese general, focused on maritime dominance, controlling key ports like Goa and Malacca, rather than engaging in local territorial disputes. Warren Hastings, the first Governor-General of Bengal (1773-1785), implemented reforms but built upon the policies of Clive and Dupleix, not initiating the first interventions in princely conflicts.

Explanation

Assertion(A) is true: The Constitution of India does not define the term "minority." While the Constitution provides for the protection of minorities through various provisions (such as Articles 29 and 30), the word "minority" itself is not defined. However, certain minority groups are recognized and protected, but the Constitution leaves the exact definition to be determined by laws, such as the National Commission for Minorities Act, 1992. Reason (R) is true: The National Commission for Minorities (NCM) is not a constitutional body; it was created under the National Commission for Minorities Act, 1992, passed by Parliament. Unlike other commissions such as the Election Commission, Union Public Service Commission (UPSC), and Comptroller and Auditor General (CAG), the NCM is a statutory body, not one established by the Constitution. However, Reason (R) does not explain Assertion (A) directly. The fact that the Minorities Commission is a statutory body does not explain why the term "minority" is not defined in the Constitution.

Explanation

The "Diamond Ring" phenomenon is a striking optical effect observed during a total solar eclipse. It occurs when a small sliver of the Sun’s light is visible around the edge of the Moon, creating the appearance of a brilliant diamond resting on a luminous ring. This effect is typically seen moments just before the eclipse reaches totality or immediately after it ends.

Explanation

Vedic literature consists of the Vedas, which are the oldest religious texts of India, comprising hymns, rituals, and philosophical teachings. It includes four Vedas--Rigveda, Yajurveda, Samaveda, and Atharvaveda--and their associated texts like the Brahmanas, Aranyakas, and Upanishads. The river most mentioned in early Vedic literature is the Sindhu. It is mentioned over 150 times in the Rig Veda, the oldest known Hindu text. The Sindhu is identical to the Indus River and is considered to be a sacred river associated with fertility, abundance and prosperity. Other rivers that are mentioned in early Vedic literature include the Saraswati, Yamuna and Ganges. Saraswati is called naditama or the best of the rivers in the Rig Veda.

Explanation

National forest policy 1988 was introduced with the principal aim of ensuring environmental stability and maintaining ecological balance including atmospheric equilibrium which are vital for sustenance of all life forms, human, animal and plant. Key objectives of National Forest Policy 1988 are:

Increasing substantially the forest/tree cover in the country through massive afforestation, reforestation and social forestry programmes Encouraging efficient utilisation of forest produce and maximising substitution of wood. Checking soil erosion and denudation in the catchment areas of rivers, lakes, reservoirs. However, the National Forest Policy of 1988 does not promote the wide use of insecticides and pesticides. Instead, it emphasizes the importance of maintaining a balanced ecosystem and preserving biodiversity within forests.

Explanation

The Eighth Five-Year Plan (1992-1997) emphasized infrastructure growth alongside economic liberalization and privatization introduced in 1991. The plan aimed to develop sectors like power, transportation, and telecommunications to drive industrial and economic growth.

Explanation

Stabilization refers to short-term macroeconomic policies aimed at reducing inflation, fiscal deficit, and balance of payments crises. It involves quick adjustments to restore financial stability. To stabilize the economy in 1991, India immediately raised interest rates to control inflation and stabilize foreign reserves. Structural adjustment refers to long-term reforms focused on improving the efficiency of the economy through trade liberalization, privatization, and regulatory reforms. These are gradual and multi-step processes. Ex-After the 1991 stabilization measures, India undertook long-term structural reforms such as liberalizing trade and privatizing state-owned enterprises.

Explanation

Full convertibility would mean the rupee exchange rate would be left to market factors without any regulatory intervention. There would be no limit on inflow or outflow of capital for various purposes including investments, remittances, or asset purchases/sales. Full convertibility of the Indian rupee is primarily aimed at promoting exports by making trade transactions easier and eliminating restrictions on currency exchange. This helps Indian exporters compete in global markets by allowing free movement of capital.

Explanation

DNA damage and permanent mutations are likely in professionals exposed to mutagenic agents like radiation, toxic chemicals, or hazardous environments.

Statement 1 is correct: Researchers using Carbon-14 isotopes are exposed to beta radiation from the radioactive isotope. Prolonged exposure can damage DNA and increase the risk of mutations.

Statement 2 is correct: X-ray technicians are at risk due to ionizing radiation, which can break DNA strands and cause chromosomal abnormalities. Protective measures like lead aprons are essential to minimize exposure.

Statement 3 is incorrect: While coal miners are exposed to harmful substances like coal dust and radon gas, these hazards are more strongly linked to respiratory diseases (e.g., black lung disease) and lung cancer, rather than direct, widespread DNA changes. Hence, it may not be included as a primary factor for widespread DNA changes.

Statement 4 is correct: Chemicals found in dyes and paints, such as benzene and lead-based compounds, can be harmful. They can cause cell damage and increase the risk of DNA changes. Long-term exposure is linked to a higher risk of cancer.

Explanation
