Multiple choice general knowledge

_____ he finishes the projections, we'll have done the necessary research to complete the project.

  1. Until the time

  2. At the time

  3. In the time

  4. By the time
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

'By the time' is the correct phrase here because it indicates that one action will be completed before another future action. 'By the time he finishes the projections' means the research will be completed when he finishes. 'Until' suggests waiting, 'At' suggests simultaneity, and 'In' suggests duration - none fit the context.
