Active-Passive voice Questions and Answers

Answer: A

Correct answer: By whom is this mess being created?

Three things must hold at once: the tense stays present continuous, so the passive is is being created; the interrogative subject who becomes the agent by whom; and because it is a question the auxiliary comes before the subject. Only the keyed option does all three.

Answer: D

Correct answer: Are others imitated by you?

The present simple question do you imitate becomes are others imitated. The auxiliary do disappears into the passive are, and the question order is kept because the sentence is still a question.

Answer: D

Correct answer: The boys who had not done their homework were punished by the teacher.

The object becomes the subject, and the relative clause who had not done their homework travels with it - which is why the option separating them makes the teacher the one who did no homework. Punished is past simple, so the passive is were punished.

Answer: C

Correct answer: This work will have been finished by tomorrow

The future perfect will have finished becomes will have been finished. By tomorrow marks the deadline and must be kept; dropping by changes the meaning to during tomorrow.

Answer: D

Correct answer: Tea is grown in Darjeeling.

Grows is present simple, so the passive is is grown. The agent Darjeeling is a place, so it appears with in rather than by. Tea grows in Darjeeling is active again, and let the tea be grown turns a statement into a command.

Answer: C

Correct answer: He was seen conducting the rehearsal

The object of saw is him, so he becomes the subject of the passive. The participle conducting is untouched. The options beginning I saw are still active, and to conduct replaces an action in progress with a completed one.

Answer: B

Correct answer: It is hoped that the match will be won by us

Hope takes a clause, so the passive needs the anticipatory it and a that clause; the inner verb then goes passive too. The option turning the whole thing into the match is hoped to be won loses the clause construction.

Answer: C

Correct answer: He was seen leaving the house by me.

The object him becomes the subject, and the participle leaving is untouched. To be leaving replaces the participle with an infinitive, and fronting leaving the house detaches it from the person it describes.

Answer: C

Correct answer: I was promised a present by my uncle.

Promise takes two objects and English prefers the person as the passive subject, so me becomes I. The past simple gives was promised, and the time phrase and agent follow. The past perfect option changes when the promise was made.

Answer: D

Correct answer: It was expected by the Romans that they would conquer Carthage

Expect here is followed by an infinitive whose subject is the same as the main subject, so the passive needs the anticipatory it and a that clause. Making Carthage the subject changes who was expecting whom, and the Romans were expected reverses it entirely.
