Question

Complete the following sentence with a suitable option:
Jane is from New Zealand. She is travelling around Europe at the moment. So far she has travelled about 1,000 miles. By the end of the trip, ___________________ (she/travel) more than 3,000 miles.

• A. she'd have travelled
  
• B. she has travelled
  
• C. she is travelling
  
• D. she'll have travelled

Answer 1

The correct option is D she'll have travelled

The future perfect is a verb tense used for actions that will be completed before some other point in the future. It is for talking about an action that will be completed between now and some point in the future. Here, the action of travelling more than 3,000 miles will be completed before a specific point of the end of the trip. Hence, Option D is correct.

The rest of the options do not express this condition. They mention actions that have already happened (option B), actions that are happening in the present (option C) or actions that are hypothetical/unreal (option A).

Hence these options are incorrect.
