Change the following from active to passive: Did the analysts anticipate the sudden market downturn?
- (a)Was the sudden market downturn anticipated from the analysts?
- (b)Had the sudden market downturn been anticipated by the analysts?
- (c)Was the sudden market downturn anticipated by the analysts?
- (d)Is the sudden market downturn being anticipated by the analysts?
Answer
Why
Correct — C. The active verb is did anticipate: did + base form, the simple past, set in a question.
The simple past passive is was/were + past participle. The new subject, the sudden market downturn, is singular, so was, and anticipate becomes anticipated.
In the question, was comes before the subject, and the analysts become the agent, by the analysts → option (c).
Why the others are wrong
- (a)Was the sudden market downturn anticipated from the analysts? — from the analysts uses the wrong preposition. The doer in a passive is introduced by by; from would make the analysts a source rather than the people who anticipated.
- (b)Had the sudden market downturn been anticipated by the analysts? — Had ... been anticipated is the past perfect passive. The active question uses did, the simple past, so the passive must stay in the simple past: Was ... anticipated.
- (d)Is the sudden market downturn being anticipated by the analysts? — Is ... being anticipated is the present continuous passive. It moves the question into the present and makes the action ongoing, which did anticipate never said.
Concept
A voice change keeps the tense. The object becomes the new subject, and the active tense decides which form of be the passive uses.
Simple past: did + verb (active) → was/were + past participle (passive).
In a did-question, did drops out. Was or were moves to the front and agrees with the new subject: Was the downturn...? Were the downturns...?
The old subject becomes the agent, introduced by by.
Key facts
- Simple past active (did + verb) becomes was/were + past participle in the passive.
- In a passive question, was or were comes before the subject: Was the downturn anticipated?
- Was or were agrees with the new subject: a singular downturn takes was.
- The agent in a passive is introduced by by, not from.

Common traps
- Choosing had been anticipated because the event is in the past, when did marks the simple past
- Accepting from in place of by for the agent
