Fill in the blank: 'Musical instruments have also __ with the ever-changing applications.'

1. evolved
2. refine
3. surge
4. diminished

Correct answer: evolved

Solution

'Musical instruments have evolved with ever-changing applications' — evolved fits the context of adapting/developing over time. 'Refine' requires 'refined' for past participle. 'Surge' and 'diminished' don't fit the context of adapting to new uses.
