Answer 2

1. will they The correct answer is 1. "will they." This is the correct form of the question tag to use with the given statement "They will have finished before nine."

A question tag is a short question added to the end of a statement to turn it into a question and to confirm information or seek agreement. In this case, the statement "They will have finished before nine" is turned into a question with the tag "will they" to confirm or seek agreement about the timing of their finishing.

The other options, "aren't they" and "won't they," are not appropriate question tags for the given statement.
