Select the option that expresses the given sentence in active voice.
The wedding hall will have been decorated by the florists before the guests arrive.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → The florists will have decorated the wedding hall before the guests arrive.
Active form of the future perfect passive:
| Change | Passive | Active | Why |
|---|---|---|---|
| Doer becomes subject | by the florists | The florists | The florists do the decorating, so they become the subject. |
| Tense kept | will have been decorated | will have decorated | “Will have been decorated” is the future perfect passive, so the active stays in the future perfect: will have + past participle (V3). Only “been” goes. |
| Subject becomes object | The wedding hall | the wedding hall (after the verb) | The wedding hall receives the action, so it goes after “will have decorated”. |
| Full sentence | The wedding hall will have been decorated by the florists before the guests arrive. | The florists will have decorated the wedding hall before the guests arrive. |
Other future perfect passives change back the same way: will have been + V3 → will have + V3. Example: The results will have been declared by the board before May. → The board will have declared the results before May.
Why the Other Options are Incorrect?
Option 1: The florists will decorate the wedding hall before the guests arrive. — Incorrect. “Will decorate” is the simple future. “Have” is dropped, so the idea of the work being finished before the guests come is lost.
Option 2: The florists will have been decorating the wedding hall before the guests arrive. — Incorrect. “Will have been decorating” is the future perfect continuous. It shows work still going on, not work that is finished.
Option 3: The florists would have decorated the wedding hall before the guests arrive. — Incorrect. “Would” is not “will”. “Would have decorated” talks of something that did not happen.
