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 ?
Show answer
Answer: B. Pair 1 is wrong: the Belle II experiment in Japan studies particle physics (B mesons), not artificial intelligence. Pair 2 is correct: blockchain is the technology behind cryptocurrencies like Bitcoin. Pair 3 is wrong: CRISPR-Cas9 is a gene-editing tool, not particle physics. So only 2.
Watch for: The topics are swapped between the pairs, so knowing just one correct link is not enough.
Why the other options are wrong
- A. Wrong because Belle II is particle physics and CRISPR is gene editing.
- C. Wrong because CRISPR-Cas9 is not linked to particle physics.
- D. Wrong because pairs 1 and 3 are swapped.
