Q1. With reference to the two-child norm for contesting local body elections, consider the following statements:
- Articles 243F and 243V empower State Legislatures to prescribe disqualification criteria for Panchayat and Municipal elections respectively.
- The Supreme Court in Javed vs State of Haryana (2003) held that the two-child norm violates Article 21 of the Constitution.
- The two-child norm was originally introduced in Rajasthan in 1995 as a population control measure.
Which of the statements given above is/are correct?
A) 1 and 3 only
B) 2 and 3 only
C) 1 only
D) 1, 2 and 3
Answer: (A) 1 and 3 only
Explanation:
- Statement 1 is correct: Articles 243F and 243V allow States to prescribe disqualifications for local bodies.
- Statement 2 is incorrect: In Javed (2003), the Supreme Court upheld the validity of the two-child norm and held that the right to contest elections is statutory, not fundamental.
- Statement 3 is correct: Rajasthan introduced the norm in 1995 as a population control measure.
Q2.
With reference to the 7th Waterbird Census (2026) in Kaziranga, consider the following statements:
- The total count recorded was 105,540 waterbirds.
- The census recorded 18 species under IUCN threatened categories.
- The number of species recorded increased compared to 2025.
Which of the statements given above is/are correct?
A) 1 and 2 only
B) 1 only
C) 2 and 3 only
D) 1, 2 and 3
Answer: (A) 1 and 2 only
Explanation:
- Statements 1 and 2 are correct: 105,540 birds across 107 species were recorded, with 18 under threatened categories.
- Statement 3 is incorrect: Species count declined by 17 compared to 2025, indicating interannual variation.
Q3.
With reference to Large Language Models (LLMs), consider the following statements:
- LLMs are trained using large clusters of GPUs.
- Training frontier LLMs requires substantial electricity and cooling infrastructure.
- The number of parameters alone guarantees superior contextual performance.
- Most frontier LLMs use transformer-based neural architectures.
How many of the above statements are correct?
A) Only One
B) Only Two
C) Only Three
D) All Four
Answer: (C) Only Three
Explanation:
- Statements 1, 2 and 4 are correct: GPU clusters, high energy use, and transformer architecture are foundational to modern LLMs.
- Statement 3 is incorrect: Model quality depends on data quality, architecture and fine-tuning, not parameter size alone.
Q4.
With reference to Carbon Capture and Utilisation (CCU), consider the following statements:
- CCU involves permanent underground storage of captured carbon dioxide.
- CCU can convert CO₂ into fuels, chemicals and building materials.
- CCU is particularly relevant for hard-to-abate industrial sectors.
- CCU eliminates the need for renewable energy transition.
How many of the above statements are correct?
A) Only One
B) Only Two
C) Only Three
D) All Four
Answer: (B) Only Two
Explanation:
- Statements 2 and 3 are correct: CCU reuses CO₂ in products and is relevant for sectors like cement and steel.
- Statement 1 describes CCS (storage), not CCU.
- Statement 4 is incorrect: CCU complements but does not replace renewable energy transition.
Q5.
Assertion (A): Earth’s energy imbalance is a critical indicator of long-term climate change.
Reason (R): A persistent positive imbalance indicates more incoming solar radiation than outgoing terrestrial radiation.
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:
Earth’s energy imbalance reflects excess trapped heat in the climate system. A persistent positive imbalance directly indicates ongoing warming, making it a key diagnostic metric for long-term climate change.
