Question 4 of 10
4. Question
Which of the following outcomes can logically result from adopting a circular economy approach in agriculture?
1. Reduction in greenhouse gas emissions
2. Improved soil organic content
3. Increased dependence on chemical fertilisers
Select the correct answer using the code below:
Correct
Answer: A
Explanation:
A circular economy in agriculture focuses on “closing the loop” by minimizing waste, recycling nutrients, and regenerating natural systems.
-
- Reduction in greenhouse gas emissions: Adopting circular practices, such as using crop residues for bioenergy or composting instead of burning them directly reduces the release of methane and nitrous oxide. It also lowers the carbon footprint associated with the production and transport of synthetic inputs.
- Improved soil organic content: Instead of discarding organic waste, circular agriculture returns it to the land through composting, vermicompost, or manuring. This replenishes organic carbon, enhances soil structure, and promotes microbial activity.

Question 5 of 10
5. Question
Which of the following best explains the historical significance of the 1946 RIN Revolt?
Correct
Answer: B
Explanation:
The Royal Indian Navy (RIN) Revolt of February 1946 was a turning point in the Indian freedom struggle because it signaled that the British could no longer rely on the loyalty of the Indian military to maintain their rule.
-
- Loss of the “Sword Arm”: For nearly two centuries, the British held India primarily through the strength of the British-led Indian armed forces. The mutiny across multiple naval ships and shore establishments (starting with the HMIS Talwar) shattered the myth of military reliability.
- Mass public support: The revolt sparked widespread sympathy strikes and hartals among the civilian population in cities like Bombay and Karachi, showing a rare moment of unity between the military and common citizens.
- Political realization: It convinced the British government, specifically the Attlee administration, that a graceful exit via the Cabinet Mission was necessary, as the instruments of colonial repression were turning against the Empire.

Question 6 of 10
6. Question
Which of the following characteristics correctly distinguish shield volcanoes?
1. Gentle slopes
2. Highly explosive eruptions
3. Low-viscosity lava
Select the correct answer using the code below:
Correct
Answer: C
Explanation:
Shield volcanoes are named for their broad, shield-like profiles, which are a direct result of their unique volcanic activity.
-
- Gentle slopes: Because the lava is highly fluid, it travels long distances from the vent before cooling. This creates thin, broad layers that accumulate into a volcano with a wide base and gentle slopes rather than a steep cone.
- Highly explosive eruptions: This is incorrect. Because the lava is fluid (low viscosity), volcanic gases can escape easily without building up immense pressure. Consequently, shield volcanoes typically have effusive (quiet) eruptions. Highly explosive eruptions are characteristic of Composite (Stratovolcanoes), where thick, high-viscosity lava traps gases and leads to violent explosions.
- Low-viscosity lava: Shield volcanoes are primarily composed of basaltic lava, which has a low silica content. This makes the lava “runny” or low-viscosity, allowing it to flow easily and quietly.

Question 7 of 10
7. Question
Large infrastructure projects in border and peripheral regions primarily contribute to:
1. Economic integration
2. Strategic connectivity
3. Fiscal centralisation
How many of the given above are correct?
Correct
Answer: B
Explanation:
-
- Economic integration: Correct. Infrastructure projects like border roads, Integrated Check Posts (ICPs), and railway links facilitate legitimate trade and commerce. By reducing transportation costs and time, these projects integrate peripheral regions (like Northeast India) with national and global supply chains, such as those in ASEAN countries.
- Strategic connectivity: Correct. A primary goal of border infrastructure is ensuring “defence readiness” and the swift movement of military forces and essential supplies. Projects by the Border Roads Organisation (BRO) are specifically designed to provide strategic depth and maintain security in remote, sensitive areas.
- Fiscal centralisation: Incorrect. While large projects are often funded by the Central government (e.g., through 10% Gross Budgetary Support for the Northeast), they do not inherently result in “fiscal centralisation,” which refers to the concentration of taxing and spending powers in the central government. Instead, these projects often involve cooperative federalism, requiring the state governments to prioritize projects and manage land acquisition. Some scholars argue that decentralized infrastructure actually empowers states by creating new local revenue streams through increased trade and tourism.
