Q1.Which of the following, if true, would weaken the projection of increased forest carbon storage?
A) Inclusion of wildfire and pest disturbance factors
B) Increase in atmospheric CO₂ levels
C) Rise in precipitation patterns
D) Lag effect in biomass response
Answer: A
Explanation:
- Core logic: Forest carbon projections depend on net biomass accumulation.
- A (Correct):
- Wildfires, pest outbreaks, and extreme events release stored carbon back into the atmosphere.
- Most models underestimate disturbance regimes, leading to overestimation of carbon sink capacity.
- Hence, inclusion of such factors weakens optimistic projections.
- B: Higher CO₂ → CO₂ fertilization effect → enhances photosynthesis → strengthens storage.
- C: Increased rainfall (if optimal) → boosts vegetation growth → supports carbon sequestration.
- D: Lag effect = delayed but eventual biomass gain → does not negate long-term increase.
Q2.Which of the following best reflects the global SAF supply–demand scenario?
A) Supply exceeds demand, leading to surplus availability
B) Supply is expected to match demand by 2050
C) Supply is significantly lower than projected demand
D) Demand is declining due to electrification
Answer: C
Explanation:
- Empirical evidence:
- Projected demand ≈ 500 million tonnes by 2050
- Expected supply ≈ ~154 million tonnes
- Inference:
- Massive supply deficit (~3× gap) → major constraint in aviation decarbonisation.
- A & B: Factually incorrect; no surplus or parity expected.
- D: Aviation electrification is technologically limited (battery constraints) → demand remains strong.
Q3. Consider the following statements:
- Expansion of credit guarantee limits under CGSS reduces lending risk for financial institutions.
- Reduced lending risk leads to increased access to capital for startups.
Which of the statements given above is/are correct?
A) 1 only
B) 2 only
C) Both 1 and 2
D) Neither 1 nor 2
Answer: C
Explanation:
- Policy transmission chain (very important for UPSC):
- Credit Guarantee → Risk Mitigation → Lending Expansion → Startup Financing
- Statement 1:
- Government guarantee covers default risk, encouraging banks/NBFCs.
- Statement 2:
- Lower perceived risk → greater credit flow to startups, especially those lacking collateral.
- Conceptual takeaway: Classic example of market failure correction via state intervention.
Q4. Consider the following statements:
- The Bharat Maritime Insurance Pool is backed by a sovereign guarantee to ensure financial stability in maritime risk coverage.
- It aims to replace global insurance mechanisms such as the International Group of Protection and Indemnity Clubs.
Which of the statements given above is/are correct?
A) 1 only
B) 2 only
C) Both 1 and 2
D) Neither 1 nor 2
Answer: A
Explanation:
- Statement 1 (Correct):
- Backed by ₹12,980 crore sovereign guarantee → enhances credibility and claim-paying capacity.
- Statement 2 (Incorrect):
- Objective is risk diversification and reduced dependence, not full replacement of global P&I clubs.
- Reflects strategic economic sovereignty + insurance sector deepening.
Q5.Assertion (A): Tobacco consumption acts as a structural barrier to poverty reduction in India.
Reason (R): Tobacco expenditure reduces household investment in nutrition, education, and healthcare.
A) Both A and R are correct and R is the correct explanation of A
B) Both A and R are correct but R is not the correct explanation of A
C) A is correct but R is incorrect
D) A is incorrect but R is correct
Answer: A
Explanation:
- Assertion (Correct):
- Tobacco creates a multi-dimensional poverty trap (health + economic burden).
- Reason (Correct and causal):
- Household budgets are finite → spending on tobacco leads to:
- Reduced nutrition intake
- Lower education expenditure
- Delayed healthcare access
- Household budgets are finite → spending on tobacco leads to:
- Causal chain:
- Tobacco spending → Human capital erosion → Lower productivity → Persistent poverty
- Conclusion: R directly explains A.
