Have the box broken.
Answer: B
Correct answer: Get someone to break the box.
Have the box broken is a causative: the speaker is not doing the breaking but arranging for it. The active equivalent therefore needs an agent to do it - get someone to break the box. Break the box makes the listener do it.

His pocket has been picked.
Answer: A
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.

People claim to have seen the suspect in several cities.
Answer: A
Correct answer: The suspect is claimed to have been seen in several cities
Two verbs go passive: people claim becomes is claimed, and to have seen becomes to have been seen. The options that convert only the second lose the claiming, which is what the sentence is chiefly about.

A stone struck me on the head.
Answer: C
Correct answer: I was struck on the head by a stone
The object me becomes the subject and a stone the agent. On the head tells where I was struck, so it stays with the verb; putting by a stone before it separates the verb from the place it acted on. Making my head the subject changes what was struck.

The clown was being laughed at by them.
Answer: B
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.

One should keep one’s promise.
Answer: A
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.
