Read the sample sentences. which answer correctly revises the sentences in passive voice by putting them into active voice? the pipes burst, spraying water everywhere. my keyboard was ruined by the water leak. the water leak was ruined by my keyboard. my keyboard was ruined because of the water leak. the water leak ruined my keyboard. my keyboard leaked water

The answer is indeed: The water leak ruined my keyboard.

In the original sentence "My keyboard was ruined by the water leak", we can notice the characteristics of the Passive Voice: the subject of the sentence, "my keyboard", suffers the action represented by the main verb instead of being the one causing/doing the action; there is the auxiliary verb "be" followed by a main verb in the participle, "was ruined"; the agent responsible for the action is preceded by the preposition "by" at the end of the sentence - "by the water leak".

To properly transform this sentence into its Active Voice counterpart, we must make the following changes: the subject now becomes the object of the verb; the auxiliary verb "be" disappears and the main verb is conjugated accordingly; the agent now becomes the subject of the sentence.

Thus: My keyboard was ruined by the water leak = The water leak ruined my keyboard.
