Match the statements from column 1 with column 2 and find which of the following pairs of statements given in the options make/s contextually and grammatically correct sense.

The correctly matched pairs are AE, BD, and CF. AE: A talks about potential of 'CRISPR-based gene therapies' and E carries this forward and concludes it (delete disease-causing mutant genes). BD: B talks about 'leadership' and the researchers' approach towards the same. This is carried forward and concluded in D (the researchers usually consider two main aspects: leadership emergence and leadership effectiveness) CF: C talks about consequences of changes in technology and F carries it forward (the consequences being universal gestures losing their value and communicative significance). Hence, d) is the correct answer.
