Change the following Active Voice to Passive Voice by choosing the right answer from the given list.
'Somebody has invited them to lunch tomorrow'.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → They have been invited to lunch tomorrow
Active to passive voice:
| Change | Active | Passive | Why |
|---|---|---|---|
| Object becomes subject | them | They | “Them” becomes “They” (the object form changes to the subject form). |
| Tense kept | has invited | have been invited | Present perfect “has invited” becomes has/have + been + past participle. With the plural subject: “have been invited”. |
| Agent (by ...) | Somebody | (by somebody) left out | When the doer is a vague word such as somebody, someone, people, the by-phrase is left out. |
| Full sentence | Somebody has invited them to lunch tomorrow. | They have been invited to lunch tomorrow |
The rest of the sentence stays as it is: "to lunch tomorrow".
Example: Somebody has stolen my bicycle. → My bicycle has been stolen.
Why the Other Options are Incorrect?
Option 1: They have been invited to lunch by somebody tomorrow — Incorrect. The verb is right, but "by somebody" should be dropped: it adds no information, and placed before "tomorrow" it makes the sentence clumsy.
Option 2: They will go to lunch somebody's house the following day. — Incorrect. It is an active sentence with a new meaning (going to someone's house) and a missing "to". Nothing is said about an invitation.
Option 4: They will be invited to lunch the next day. — Incorrect. "will be invited" is the future passive. The invitation has already been made (present perfect), so the tense is wrong.
