Select the option that expresses the given sentence in passive voice.
Martha made pancakes yesterday.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Pancakes were made by Martha yesterday.
To transform the sentence into passive voice, the object of the active sentence ("pancakes") becomes the subject.
The verb is adjusted by using the correct form of the auxiliary verb "to be" based on the tense and number, followed by the past participle of the main verb.
Since the active sentence is in the past tense ("made"), the auxiliary verb becomes "were" for the plural subject "pancakes."
The agent ("Martha") is introduced with "by," and the time adverbial ("yesterday") remains unchanged.
Thus, the active sentence becomes the passive sentence "Pancakes were made by Martha yesterday."
