Choose the appropriate Active Voice for the given sentence-
He was appointed monitor by the teacher.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → The teacher appointed him monitor.
Passive (simple past) to active:
| Change | Passive | Active | Why |
|---|---|---|---|
| Agent (by ...) becomes subject | by the teacher | The teacher | The doer in the by-phrase (the teacher) becomes the subject. |
| Tense kept | was appointed | appointed | “Was + past participle” becomes the simple past: “was appointed” becomes “appointed”. |
| Subject becomes object | He | him | The passive subject becomes the object: “he” becomes “him”. The complement “monitor” stays after it. |
| Full sentence | He was appointed monitor by the teacher. | The teacher appointed him monitor. |
Example: She was chosen captain by the players. → The players chose her captain.
Why the Other Options are Incorrect?
Option 2: He appointed monitor by the teacher. — Incorrect. "He" is still the subject and the by-phrase remains. The sentence is neither active nor grammatical.
Option 3: The teacher had appointed him monitor. — Incorrect. "had appointed" is the past perfect. The given sentence is in the simple past.
Option 4: The teacher was appointed him monitor. — Incorrect. "was appointed" is still a passive form and makes no sense with "him".
