Statement I: Article 279A empowers the President to constitute a joint forum of the Centre and the States called the GST Council.
Statement II: The GST Council is chaired by the Prime Minister of India.
Explanation
Article 279A empowers the President to constitute the GST Council, which serves as a joint forum for the Centre and the States. However, the council is chaired by the Union Finance Minister, not the Prime Minister. This structure ensures that fiscal policies regarding GST are decided through a deliberative process involving representatives from all states and the central finance ministry for collective governance.
Q4153. Enteric fermentation is a major source of greenhouse gas emissions. This process is primarily associated with:
Explanation
Enteric fermentation is a natural digestive process occurring in ruminant animals like cattle, sheep, and goats. Microorganisms in the rumen break down plant material, producing methane as a byproduct, which is then released into the atmosphere. This process is a significant anthropogenic source of methane, making livestock management a key area for reducing agricultural greenhouse gas emissions and addressing global warming.
Q4154. Which pair correctly matches the future opportunity in the service sector with its corresponding domain?
Explanation
Future opportunities in services are often linked to specialized domains that address global challenges. Green services, which include carbon auditing and sustainability consulting, belong to the environmental consulting domain. This field helps businesses meet regulatory requirements and improve their ecological footprint. Other emerging areas include precision analytics for various industries, though they must be correctly matched with their respective functional sectors.
Q4155. Among the following communities, which was traditionally NOT recognized as a primary agricultural community in 19th-century Rajasthan?
Explanation
In nineteenth-century Rajasthan, communities like the Jats, Bishnois, and Dhakars were primarily recognized for their agricultural activities and formed the backbone of the rural economy. In contrast, the Oswal community belonged to the Mahajan class and was traditionally involved in trade, commerce, and banking rather than agricultural labor, occupying an influential position in the state’s urban and financial sectors.
Q4156. Read the following statements regarding scientific knowledge in Vedic texts:
I. The Rigveda describes an ancient calendar system based on lunar and solar cycles.
II. The Atharvaveda contains references to the anatomy of the human body.
III. The Vedic people possessed the knowledge of working with metals like copper and bronze.
IV. The concept of zero was mathematically formalized with a symbol in the early Rigvedic hymns.
Which of the above statement(s) is/are correct?
I. The Rigveda describes an ancient calendar system based on lunar and solar cycles.
II. The Atharvaveda contains references to the anatomy of the human body.
III. The Vedic people possessed the knowledge of working with metals like copper and bronze.
IV. The concept of zero was mathematically formalized with a symbol in the early Rigvedic hymns.
Which of the above statement(s) is/are correct?
Explanation
Vedic texts demonstrate significant early scientific knowledge, including a calendar system based on celestial cycles, basic anatomical observations, and the practical use of metals like copper. However, while the concept of "nothingness" or zero existed philosophically, the mathematical formalization of zero as a specific numeric symbol and its use in calculations were developments that occurred later in the post-Vedic period.
Q4157. The following question consists of two statements -- Assertion (A) and Reason (R). Answer the question by selecting the appropriate option:
Assertion (A): The introduction of GST in India is often cited as a prime example of ‘cooperative federalism’.
Reason (R): The GST Council requires both the Union and the States to participate in decision-making regarding tax rates, exemptions, and thresholds through a consensus-building mechanism.
Assertion (A): The introduction of GST in India is often cited as a prime example of ‘cooperative federalism’.
Reason (R): The GST Council requires both the Union and the States to participate in decision-making regarding tax rates, exemptions, and thresholds through a consensus-building mechanism.
Explanation
The GST framework is a significant achievement in cooperative federalism because it mandates collective decision-making. The GST Council brings together the Union and all States to decide on tax rates, exemptions, and administrative rules. This consensus-building approach ensures that both levels of government have a stake in the indirect tax system, fostering a collaborative environment for national economic growth and stability.
Q4158. Match List-I with List-II regarding the impacts of climate change on specific ecosystems:
Select the correct answer from the codes given below:
| Ecosystem | Specific Impact |
|---|---|
| A. Coral Reefs | i. Widespread bleaching events due to thermal stress |
| B. Arctic Tundra | ii. Accelerated permafrost thaw releasing trapped greenhouse gases |
| C. Tropical Rainforests | iii. Increased vulnerability to sea-level rise and coastal squeeze |
| D. Coastal Mangroves | iv. Heightened risk of desiccation and increased frequency of forest fires |
Explanation
Different ecosystems face unique threats from climate change. Coral reefs are highly sensitive to thermal stress, leading to bleaching. The Arctic tundra is impacted by permafrost thaw, which releases greenhouse gases. Tropical rainforests face higher risks of fire and drying. Coastal mangroves are vulnerable to rising sea levels and limited space for landward migration. Recognizing these specific vulnerabilities is crucial for targeted conservation.
Q4159. Read the following statements regarding the General Agreement on Trade in Services (GATS):
Statement I: GATS is a treaty of the World Trade Organization (WTO) that extends the multilateral trading system to the service sector.
Statement II: GATS forces all member countries to privatize their public healthcare and education sectors.
Select the correct response:
Statement I: GATS is a treaty of the World Trade Organization (WTO) that extends the multilateral trading system to the service sector.
Statement II: GATS forces all member countries to privatize their public healthcare and education sectors.
Select the correct response:
Explanation
The General Agreement on Trade in Services is a multilateral treaty under the World Trade Organization designed to liberalize global trade in services. While it establishes a framework for reducing trade barriers, it does not force member countries to privatize essential public sectors like healthcare and education. Governments retain the policy space to provide public services according to their national priorities.
Q4160. Read the following statements and select the correct option:
Statement I: Snow Leopards are threatened primarily by retaliatory killing by herders, poaching, and climate change.
Statement II: The Global Snow Leopard and Ecosystem Protection Program (GSLEP) is an intergovernmental alliance of range countries.
Statement I: Snow Leopards are threatened primarily by retaliatory killing by herders, poaching, and climate change.
Statement II: The Global Snow Leopard and Ecosystem Protection Program (GSLEP) is an intergovernmental alliance of range countries.
Explanation
Snow leopards face severe threats from poaching, climate change, and retaliatory killing by herders whose livestock are preyed upon. To address these challenges, the Global Snow Leopard and Ecosystem Protection Program was formed as an alliance among the twelve countries where the species is found. Both statements accurately reflect the primary threats to the species and the international collaborative response.Answer key for these questions
