Q1.Which of the following countries are major uranium suppliers to India?

1. Kazakhstan
2. Canada
3. Australia
4. Russia

Select the correct answer using the code below:

A) 1 and 2 only
B) 1, 2 and 3 only
C) 2, 3 and 4 only
D) 1, 2, 3 and 4

Q1. (D)

Explanation:

• India imports uranium from Kazakhstan (largest supplier), Canada, Australia, and Russia.
• Diversification strengthens fuel security for PHWRs and reduces geopolitical supply risks.
• Enabled after 2008 NSG waiver allowing global civil nuclear commerce with India.

Q2.With reference to India’s HADR (Humanitarian Assistance and Disaster Relief) doctrine, consider the following statements:

1. It is integrated into India’s maritime strategy.
2. It enhances India’s soft power and regional credibility.
3. It requires a UN Security Council resolution for deployment.

Which of the statements given above is/are correct?

A) 1 and 2 only
B) 2 only
C) 1 and 3 only
D) 1, 2 and 3

Q2. (A)

Explanation:

• Statement 1: Correct — HADR is embedded in India’s maritime doctrine and SAGAR vision.
• Statement 2: Correct — Enhances India’s image as a net security provider in the IOR.
• Statement 3: Incorrect — HADR missions do not require UNSC authorisation; they are sovereign deployments based on consent.

Q3.Assertion (A): Nucleic Acid Testing (NAT) reduces the window period in detection of transfusion-transmitted infections.
Reason (R): NAT detects antibodies produced by the host immune system against viral pathogens.

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

Q3. (C)

Explanation:

• Assertion: Correct — NAT detects infection earlier by identifying viral RNA/DNA, thereby reducing the diagnostic window period.
• Reason: Incorrect — Antibody detection is done by ELISA, not NAT.
• Hence, NAT improves blood safety by molecular detection, not immune-response detection.

Q4.The term hydrological hysteresis refers to:

A) Seasonal variation in monsoon rainfall
B) Linear proportionality between rainfall and river discharge
C) Non-linear relationship between rainfall and runoff
D) Delay between cloud formation and precipitation

Q4. (C)

Explanation:

• Hydrological hysteresis describes a non-linear, path-dependent rainfall–runoff relationship.
• River discharge depends on antecedent soil moisture and catchment saturation, not rainfall alone.
• Explains why floods may persist even after rainfall subsides.

Q5.According to the Living Planet Report 2024, which of the following ecosystems has experienced the highest decline in wildlife populations (1970–2020)?

A) Marine ecosystems
B) Terrestrial ecosystems
C) Freshwater ecosystems
D) Polar ecosystems

Q5. (C)

Explanation:

• Freshwater species declined by 85%, the highest among ecosystems.
• Terrestrial species declined by 69%.
• Marine species declined by 56%.
• Freshwater collapse signals severe ecosystem stress and biodiversity crisis.
