Answer and explanation

Correct answer: D. If the committee were to approve the plan, work could begin in May.

  1. Step 1: 'If + were to + base verb' is a formal way to express an unlikely future condition. Step 2. The main clause uses 'could', which matches. Answer: If the committee were to approve the plan, work could begin in May. Why not the others: 'would' and 'will' cannot follow 'if' here; the participle form lacks a verb.
