Question

The older violins no longer had _____ original parts, but each violinist played _____ instrument well. Which pair of pronouns correctly completes the sentence?
their; his or her

its; his or her

its; their

their; their

Answer 1

The answer is (Their ; his or her)

Answer 2

The older violins are more than one object, in this case its cannot be used, only their; each violinist could mean male or female, so it would be possible the use of his or her or their (applied for either),but there is only the latter option. The correct answer is their/their.

The older violins no longer had their original parts, but each violinist played their instrument well.
