Change the following from active to passive: They had been making the staff report discrepancies silently.
- (a)The staff had been made to report discrepancies silently.
- (b)The staff were made to report discrepancies silently.
- (c)Discrepancies had been reported silently by the staff.
- (d)The staff had been made report discrepancies silently.
Answer
Why
Correct — A. The active uses causative make: make + object + bare infinitive, as in had been making the staff report.
In the passive, the staff becomes the subject and the bare infinitive takes to: made to report.
The past perfect is kept as had been made, and the vague doer they is left out. 'The staff had been made to report discrepancies silently' → option (a).
Why the others are wrong
- (b)The staff were made to report discrepancies silently. — were made is simple past. It keeps the to, but drops the past perfect had, which places the making before another past event.
- (c)Discrepancies had been reported silently by the staff. — Discrepancies had been reported is the passive of a different sentence, 'The staff had reported discrepancies'. The causative make, which the stem turns on, disappears.
- (d)The staff had been made report discrepancies silently. — made report leaves out to. The active uses a bare infinitive after make, but the passive needs the to-infinitive: made to report. The tense matches option (a), and the to is what is missing.
Concept
Causative make has one pattern in each voice.
Active: make + object + bare infinitive, as in They made the staff report.
Passive: be made + to-infinitive, as in The staff were made to report.
See, hear and help work the same way: 'They saw him leave' becomes 'He was seen to leave'.
The tense rides on make, and the rest of the sentence, discrepancies silently, carries over unchanged.
A strict conversion keeps the continuous as well: 'The staff had been being made to report discrepancies silently.' That form is rare, and no option prints it.
Option (a) is the one that keeps both the past perfect and the to-infinitive.
Key facts
- Causative make, active: make + object + bare infinitive (made them wait).
- Causative make, passive: be made + to-infinitive (they were made to wait).
- See, hear and help follow the same pattern: he was seen to leave.
- A vague agent such as by them can be left out of the passive.

Common traps
- Keeping the bare infinitive in the passive (made report) because the active has none
- Letting the past perfect slip to simple past (were made to report)
- Making discrepancies the subject, which converts a different sentence and loses make
