Reason (R).
Assertion (A): India is a Republic.
Reason (R): The President of India, who is the head of the state, is indirectly elected by the people for a fixed tenure of five years.

Specifically, the President of India is indirectly elected by an electoral college consisting of elected members of both Houses of Parliament and the Legislative Assemblies of the States for a fixed tenure. This election is the defining characteristic of a republic.

Explanation
Green GDP is an economic indicator that adjusts the standard Gross Domestic Product to reflect environmental factors. It subtracts the monetary value of natural resource depletion and the costs of environmental degradation from the total output. By accounting for the loss of biodiversity and the damage caused by pollution, Green GDP provides a more accurate measure of sustainable economic performance.
Q365. Sound waves in air are characterized as:
Explanation
Sound waves in air are classified as longitudinal mechanical waves because the particles of the medium vibrate back and forth in the same direction that the wave travels. These waves consist of alternating regions of high pressure, called compressions, and low pressure, called rarefactions. Because they require a physical medium like air to propagate, sound cannot travel through a vacuum.
Q366. Read the following statements regarding Chalcolithic economies and select the correct option:
Statement I: The Chalcolithic economies of Rajasthan were predominantly agro-pastoral.
Statement II: Evidence from sites like Balathal indicates the cultivation of diverse crops including wheat and barley.
Statement I: The Chalcolithic economies of Rajasthan were predominantly agro-pastoral.
Statement II: Evidence from sites like Balathal indicates the cultivation of diverse crops including wheat and barley.
Explanation
The Chalcolithic economies in Rajasthan were primarily agro-pastoral, combining the cultivation of crops with animal husbandry. Evidence from major sites like Balathal confirms the farming of various crops, including wheat, barley, and lentils. This stable food supply, supplemented by the rearing of cattle, sheep, and goats, allowed these communities to establish permanent village settlements and develop specialized craft industries.
Q367. Which of the following is true regarding the Great Granary of Mohenjo-daro?
Explanation
The Great Granary is the largest structure identified at the site of Mohenjo-daro. Located on the citadel mound, it consists of a massive brick foundation with air ducts to keep the grain dry. This building reflects the civilization’s ability to collect and store large agricultural surpluses, which were likely used to support the urban population and provide stability.
Q368. The term ‘Democratic Republic’ in the Preamble ensures which of the following?
Explanation
The term ‘Democratic Republic’ in the Indian context signifies that political sovereignty lies with the people and that there is an absence of any privileged class. Consequently, all public offices, from the President down to the local level, are open to every citizen without any discrimination based on caste, creed, or religion. This promotes political equality and ensures a truly representative government.
Q369. Match List-I (Local Desert Feature) with List- II (Description) and select the correct answer using the codes given below:
| Local Desert Feature | Description |
|---|---|
| A. Erg | i. Rocky desert plateau |
| B. Reg | ii. Sandy desert with dunes |
| C. Hamada | iii. Dry riverbed |
| D. Wadi | iv. Stony desert plain |
Explanation
Desert landscapes are classified by their surface characteristics. An erg is a vast area of shifting sand dunes. A reg is a stony plain covered with gravel and pebbles. A hamada is a high, rocky desert plateau where most sand has been removed by wind. A wadi is a dry riverbed that may fill with water during rare, heavy rain events.
Q370. Which of the following represents a significant challenge in accurately measurement of Green GDP?
Explanation
One of the greatest obstacles to calculating Green GDP is the difficulty of valuing environmental assets. Unlike manufactured goods, many ecosystem services, such as clean air or biodiversity, do not have market prices. Economists must use complex estimation techniques to assign a monetary cost to pollution or resource loss. These valuations are often subjective and vary widely, making standardized measurement difficult.Answer key for these questions
