Consider the following pairs

Explanation

S1: 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 designedto study violations of the Standard Model of particle physics. S2: A block chain is a digitized, decentralized, public ledger of all crypto currency 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 block chain, which is downloaded automatically. S3: CRISPR technology is a simple yet powerful tool for editing genomes. It allows researchers to easily alter DNA sequences and modify gene function. Its many potential applications include correcting genetic defects, treating and preventing the spread of diseases and improving crops. However, its promise also raises ethical concerns.
