Answer 1

"By the time Cynthia books the flight to Iceland, she has called her sister about the visit.

The answer will be the “has called” because all other options like “will have called” is not the proper tense that’s why it is not applicable to the answer.

“Calls” will not be the answer because it is the present tense. “Will have called” will also not be the answer because it is the future tense.

So the answer will be has called.
