Consider the following pairs : Terms sometimes seen in news — Context/Topic 1. Belle II experiment — Artificial Intelligence 2. Blockchain technology — Digital/Cryptocurrency 3. CRISPR – Cas9 — Particle Physics Which of the pairs given above is/are correctly matched ?
- (a) 1 and 3 only
- (b) 2 only ✓ UPSC's answer
- (c) 2 and 3 only
- (d) 1, 2 and 3
Why the answer is (b)
• Pair 2 is correct: blockchain is the distributed-ledger technology underlying Bitcoin and other cryptocurrencies.
• Pair 1 is wrong: Belle II is a particle-physics experiment at the SuperKEKB accelerator in Japan studying B-mesons, with Indian participation; it is not about AI.
• Pair 3 is wrong: CRISPR-Cas9 is a gene-editing tool in biotechnology, not particle physics.
• Hence 2 only, option (b).
Why the other options are wrong
- (a) 1 and 3 only
- Both pairs 1 and 3 are mismatched.
- (c) 2 and 3 only
- Pair 3 is wrong: CRISPR is gene editing.
- (d) 1, 2 and 3
