Select the correct option to transform the given Active Voice sentence into Passive Voice.
Don't make a noise.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Let no noise be made
Passive of a negative command:
An imperative (command) becomes passive with Let + object + be + past participle.
| Change | Active | Passive | Why |
|---|---|---|---|
| Opening words | Don’t | Let | The sentence stays a command. |
| Object becomes subject | a noise | no noise | “Don’t” is shown by no before the object (or “Let not ... be”): “a noise” becomes “no noise”. |
| Verb | make | be made | “Make” becomes “be made”. |
| Full sentence | Don’t make a noise. | Let no noise be made. |
No agent is added, as the command is to anyone present.
Example: Shut the door. → Let the door be shut.
Why the Other Options are Incorrect?
Option 1: Noise not to be made — Incorrect. It has no finite verb and no "let", so it is not a complete sentence or a command.
Option 2: No noise is made — Incorrect. It is a statement of fact in the simple present, not a command.
Option 4: Not to make a noise — Incorrect. It is still active ("make a noise") and only a phrase, not a sentence.
