Answer
will have built

The correct answer is will have built — 6. Final sentence: "By next month, they will have built the new library."

Step-by-step solution

  1. 1. The time reference "by next month" points to a future completion.
  2. 2. The clause describes an action that will be finished before another future event.
  3. 3. Choose the future perfect tense: "will have" + past participle.
  4. 4. The past participle of "build" is "built".
  5. 5. Combine to form "will have built".
  6. 6. Final sentence: "By next month, they will have built the new library."
Common mistake: Selecting simple future instead of future perfect

Concept tested: Future Perfect tense
