Here is Question No. 64 a part of our series on UPSC Prelims 2018
Q64. Consider the following pairs:
Terms sometimes seen in news Context/Topic
Belle II experiment: Artificial Intelligence
Blockchain: Digital/Technology Cryptocurrency
CRISPR-Cas9: Particle Physics
Which of the pairs given above is/are correctly matched? (a) 1 and 3 only (b) 2 only (c) 2 and 3 only (d) 1, 2 and 3
Answer: B
Pair 1 is not correctly matched: The Belle II experiment is designed to record data at Super KEKB, a 3 km circumference asymmetric electron-positron collider with a performance similar or better than Belle or BaBar, the B factory detectors, in a much more severe beam background environment. Belle-2 experiment in Tsukuba, Japan, by The High Energy Accelerator Research Organisation (KEK) is designed to study violations of the Standard Model of particle physics.
Pair 2 is correctly matched: A blockchain is a digitized, decentralized, public ledger of all cryptocurrency transactions. Constantly growing as ‘completed’ blocks (the most recent transactions) are recorded and added to it in chronological order, it allows market participants to keep track of digital currency transactions without central recordkeeping. Each node (a computer connected to the network) gets a copy of the blockchain, which is downloaded automatically.
