Previous Year UPSC Questions

Explanation

Full Convertibility refers to a currency’s ability to be freely exchanged for any other currency without restrictions, both for current account transactions (like trade in goods and services) and capital account transactions (like investments and loans).

Statement 1 is correct: Full convertibility means the rupee can be freely exchanged with other international currencies without restrictions on the exchange rate, allowing it to float based on market demand and supply.

Statement 2 is correct: Full convertibility would enable the rupee to be directly exchanged with any foreign currency at both domestic and international financial institutions, facilitating smoother global trade and investment transactions.

Statement 3 is correct: A fully convertible rupee would function like an international currency, allowing unrestricted movement of capital across borders, making India more integrated into the global economy.

Explanation

Statement 1 is incorrect: The Chief Election Commissioner (CEC) and other Election Commissioners (ECs) have equal powers and responsibilities within the Election Commission of India. They receive equal salaries as well and there is no disparity in salaries between the Chief Election Commissioner and the other Election Commissioners.

Statement 2 is correct: The Chief Election Commissioner is entitled to the same salary as is provided to a judge of the Supreme Court. Note: This fact was correct in accordance to the year in which it was asked. As per latest amendments in the Chief Election Commissioner and Other Election Commissioners (Appointment, Conditions of Service, and Term of Office) Act, 2023, the salary of the Chief Election Commissioner (CEC) and Election Commissioners (ECs) is now equivalent to that of the Cabinet Secretary.

Statement 3 is correct: The removal process for the Chief Election Commissioner mirrors that of a Supreme Court judge. This safeguards the CEC’s independence and ensures impartiality in their role. While an EC can be removed on the CEC’s recommendation.

Statement 4 is incorrect: An Election Commissioner serves a term of six years or until they reach the age of 65, whichever comes earlier. This discrepancy makes the statement incorrect.

Explanation

The Finance Commission plays a crucial role in India’s fiscal structure. It is a constitutional body constituted by the President of India every five years, or more frequently if deemed necessary. Its primary responsibility is to recommend the distribution of financial resources between the central and state governments. One key function of the Finance Commission is to propose principles and guidelines for distributing grants-in-aid to states from the Consolidated Fund of India. These grants aim to support states in addressing fiscal needs, ensuring balanced regional development, and mitigating economic disparities among states.

Explanation

A lagoon is a shallow body of water separated from a larger sea or ocean by a barrier, such as a sandbar, coral reef, or barrier island. Lagoons are typically found along coastlines and are connected to the ocean by narrow inlets.

Option (c) is correct: Periyar Lake (Kerala) is an artificial freshwater lake formed by the construction of the Mullaperi-yar Dam on the Periyar River. It is not a lagoon. Options (a), (b) and (d) are incorrect:

Ashtamudi Lake is a brackish water lagoon in Kerala connected to the Arabian Sea. Chilka Lake (Odisha) is the largest brackish water lagoon in India and is connected to the Bay of Bengal. Pulicat Lake (Andhra Pradesh and Tamil Nadu) is the second-largest brackish water lagoon in India and is connected to the Bay of Bengal.

Explanation

The climatic data provided matches the conditions of Chennai, which has a tropical wet and dry climate. Chennai experiences an average annual temperature of around 26°C, with a moderate annual temperature range of about 9°C due to its coastal location. The average annual rainfall of 120-140 cm is typical of Chennai, primarily influenced by the Northeast Monsoon. Other locations do not fit this profile: Allahabad and Kolkata have larger temperature ranges due to their continental climates, while Cherrapunji receives significantly higher rainfall, averaging over 450 cm annually. Hence, the station is most likely Chennai.

Explanation

It is a migratory species that travels thousands of miles from South America and other regions to nest on the beaches of Orissa.

Explanation

The mountain areas do not account for above thirty percent of the surface area of the country. Mountainous regions, including the Himalayas and other ranges, account for less than 30% of total surface area. The majority of India’s land area consists of plains (43%) and plateaus (27%). India receives a significant amount of rainfall, and about one-third of its area does receive more than 750 mm of annual rainfall, especially in regions like the Western Ghats, northeastern India, and coastal areas. Wells, including tube wells, are the largest source of irrigation in India, accounting for more than 60% of the irrigated area. Groundwater is extensively used for agriculture. The northern plains of India, formed by the Indus, Ganges, and Brahmaputra river systems, are predominantly covered by fertile alluvial soil, which is ideal for agriculture.

Explanation

Option (d) is correct: Open stunted forests with bushes, small trees, long roots, and sharp thorns or spines are typical features of tropical thorn forests, which thrive in regions with low rainfall (25-75 cm annually) and semi-arid climates. Among the above, Western Andhra Pradesh experiences a dry climate with low rainfall, making it suitable for thorny vegetation such as acacia, babul, and cactus. The trees in these regions develop long roots to reach groundwater and spiny leaves to reduce water loss through transpiration. Options (a), (b) and (c) are incorrect:

Eastern Odisha has a more humid climate due to its proximity to the Bay of Bengal and receives higher rainfall. The vegetation here is more likely to be tropical moist deciduous or mangrove forests, not thorn forests. North-Eastern Tamil Nadu, including regions like Chennai, receives moderate rainfall and has a mix of dry deciduous and coastal vegetation. Thorn forests are not predominant here. The Shivalik Hills and Terai region (foothills of the Himalayas) have a subtropical climate with high rainfall. The vegetation here is typically tropical moist deciduous or subtropical forests, not thorn forests.

Explanation

A mangrove is a unique ecosystem of salt-tolerant trees and shrubs that grow in tropical and subtropical coastal intertidal zones. These plants have specialized roots (e.g., stilt roots or pneumatophores) to survive in saline, waterlogged conditions. Mangroves provide critical habitats for marine life, protect coastlines from erosion, and act as carbon sinks.

Option (d) is the correct:

A is matched with 4: Achra Ratnagiri is a mangrove region located in Maharashtra state. B is matched with 1: Coondapur, also known as Kundapura, is a mangrove region situated in the state of Karnataka. C is matched with 5: Pichavaram is a famous mangrove forest located in Tamil Nadu. D is matched with 2: Vembanad is a lagoon and mangrove area in Kerala.

Explanation

The world’s highest ground-based telescopic observatory is the Indian Astronomical Observatory (IAO), located in Hanle, Ladakh, India, at an altitude of 4,500 meters (14,764 feet). The Indian Institute of Astrophysics (IIA), an autonomous institute under the Department of Science and Technology, operates the observatory, ensuring optimal conditions for astronomical research.
