Which of the following options is the most suitable conversion of the following sentence into Passive Voice?
Did the Romans defeat the Greeks?
Show answer & explanation
Correct answer: D
Explanation
The original sentence "Did the Romans defeat the Greeks?" is in the simple past tense, active voice, and is an interrogative sentence (a question).
In the active voice sentence, "The Romans" is the subject and "the Greeks" is the object. In the passive voice, "The Greeks" becomes the subject.
The auxiliary verb for a simple past tense question in the passive voice is "was" or "were", depending on the new subject. Since "Greeks" is plural, "were" is the correct choice.
The main verb "defeat" must be changed to its past participle form, "defeated".
The structure for a passive voice question in the simple past tense is: Auxiliary Verb (Was/Were) + Subject + Past Participle + by + Object?
Option D follows this structure: "Were the Greeks defeated by the Romans?"
