Choose the correct option after changing the following sentence into Passive Voice :
Could you pass the test?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Could the test be passed ?
Passive of a question with a modal:
| Change | Active | Passive | Why |
|---|---|---|---|
| Object becomes subject | the test | the test | The object “the test” becomes the subject. |
| Tense kept | could pass | could be passed | Modal + be + past participle: “could pass” becomes “could be passed”. |
| Question order | Could you | Could the test | The modal comes first: “Could the test be passed?” |
| Agent (by ...) | you | – (dropped) | “By you” may be left out, since the doer is understood. |
| Full sentence | Could you pass the test? | Could the test be passed ? |
Example: Can you solve this problem? → Can this problem be solved by you?
Why the Other Options are Incorrect?
Option 1: Could the test been passed ? — Incorrect. A modal is followed by the base form "be". "Been" needs "have" before it ("could have been passed"), which would also change the time.
Option 2: Could the test pass ? — Incorrect. It is still active, and it makes the test the doer, as if the test itself could pass.
Option 4: Could the test being passed ? — Incorrect. A modal is never followed by an -ing form. "Being" is wrong after "could".
