Change the following from active to passive: The jury has delivered a unanimous verdict.
- (a)A unanimous verdict has been delivered by the jury.
- (b)A unanimous verdict was being delivered by the jury.
- (c)A unanimous verdict had been delivered by the jury.
- (d)A unanimous verdict is delivered by the jury.
Answer
Why
Correct — A. The active verb has delivered is present perfect: has + past participle.
Present perfect passive = has/have + been + past participle.
The object a unanimous verdict becomes the subject. It is singular, so it takes has: A unanimous verdict has been delivered by the jury → option (a).
Why the others are wrong
- (b)A unanimous verdict was being delivered by the jury. — Was being delivered is the past continuous passive. It would come from The jury was delivering a unanimous verdict, not from has delivered.
- (c)A unanimous verdict had been delivered by the jury. — Had been delivered is the past perfect passive, the passive of The jury had delivered. It moves the time back a step, and has must stay has.
- (d)A unanimous verdict is delivered by the jury. — Is delivered is the simple present passive, from The jury delivers. It drops the perfect, so the verdict is no longer presented as already delivered.
Concept
When a sentence changes voice, the tense does not change. The passive keeps the tense and aspect of the active verb and adds be in the matching form.
Present perfect active: has/have + past participle (has delivered).
Present perfect passive: has/have + been + past participle (has been delivered).
The active object becomes the passive subject, the active subject moves into a by-phrase, and has or have agrees with the new subject.
All four options share the same words around the verb, A unanimous verdict … delivered by the jury. Only the verb phrase differs, so the whole item is a tense check.
Key facts
- Present perfect passive: has/have + been + past participle.
- The helping verb agrees with the new subject: A verdict has been …, Verdicts have been ….
- Had been + past participle is the passive of the past perfect (had + past participle), a different tense.

Common traps
- Choosing had been delivered because both perfects contain been. The active has fixes has in the passive.
- Choosing is delivered because the active is in the present, and dropping the perfect aspect.
