Change the following from active to passive: Did the council approve the comprehensive zoning plan?
- (a)Has the comprehensive zoning plan been approved by the council?
- (b)Is the comprehensive zoning plan being approved by the council?
- (c)Was the comprehensive zoning plan being approved by the council?
- (d)Was the comprehensive zoning plan approved by the council?
Answer
Why
Correct — D. The active question is in the simple past: 'Did the council approve...?'
Simple past passive is was/were + past participle. The object, 'the comprehensive zoning plan', becomes the subject, 'approve' becomes approved, and the council moves into a by-phrase.
In a question, was goes before the subject and 'did' drops out → option (d).
Why the others are wrong
- (a)Has the comprehensive zoning plan been approved by the council? — Has ... been approved is present perfect passive. It is the passive of 'Has the council approved the plan?', not of a question asked with 'did'.
- (b)Is the comprehensive zoning plan being approved by the council? — Is ... being approved is present continuous passive, the passive of 'Is the council approving the plan?'. The tense has moved from past to present.
- (c)Was the comprehensive zoning plan being approved by the council? — Was ... being approved keeps the past but adds the continuous 'being'. That is the passive of 'Was the council approving the plan?', not of 'Did the council approve'.
Concept
A voice change keeps the tense. Only the helping verb changes to carry it: simple past active 'approved' becomes simple past passive was approved.
In a yes/no question, 'did' exists only to build the active question. The passive has its own auxiliary, was or were, so that auxiliary moves before the subject and 'did' disappears.
Match it to the new subject: 'the plan' is singular, so was.
All four options keep 'by the council', so the doer does not separate them. Tense and aspect do, and 'Was ... approved' is the simple past among them.
Key facts
- 'Did X approve Y?' becomes 'Was Y approved by X?' ('Were' for a plural Y).
- Present perfect passive: has/have been + past participle.
- Continuous passives add 'being': is/was being + past participle.

Common traps
- Choosing 'Was ... being approved' because it keeps 'was', without noticing that 'being' makes it past continuous
- Choosing 'Has ... been approved' because it sounds formal, though the active is simple past
