Active-Passive voice Questions and Answers

Answer: B

Correct answer: Even a little mouse may help a lion

Turning the passive active makes the agent the subject: a little mouse may help a lion. Even qualifies a little mouse, so it stays in front of it; moving it before help makes it qualify the helping instead. Can and ought to change the modal.

Answer: D

Correct answer: A promise should be kept

The indefinite subject one disappears in the passive, and one's promise becomes simply a promise. Keeping one's leaves a possessive with nobody to own it, and by us introduces an agent the original never names.

Answer: C

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: A

Correct answer: Why is time wasted by you?

The present simple question why do you waste becomes why is time wasted. The auxiliary do is absorbed into the passive is, and the perfect and continuous options change the tense of a habit.

Answer: D

Correct answer: After being driven to the museum, Professor Kumar was dropped at his hotel.

Both clauses go passive together. The participial phrase after driving becomes after being driven, and it must attach to the new subject - Professor Kumar - which is exactly why the options keeping she as subject leave a dangling modifier. Dropped him then becomes was dropped.

Answer: D

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: C

Correct answer: The police arrested him on a charge of theft, but for lack of evidence released him.

Both halves go active. The first passive, he was arrested, needs an agent, and the police are the understood one; the second, he was released, shares that subject and so becomes released him. The option that leaves he was released converts only half the sentence.

Answer: D

Correct answer: Someone has picked his pocket

Turning the passive active needs an agent, and where none is given English supplies the indefinite someone. The present perfect has been picked becomes has picked. The other options keep the passive or turn the verb into a noun.

Answer: D

Correct answer: I remember being taken to the museum by my sister

The verb remember takes a gerund, so the passive must also be a gerund: being taken. I remember I was taken replaces the gerund with a clause, and myself being taken adds a reflexive the construction does not need.

Answer: A

Correct answer: They were laughing at the clown.

Laugh at is a prepositional verb, so in the active the preposition returns to its normal place before the object. The past continuous was being laughed at becomes were laughing; the plain past option changes the aspect.
