Choose the correct option to change the given sentence from the Active to the Passive Voice.
My grandfather built this home in 1930.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → This home was built in 1930 by my grandfather.
Active to passive voice (simple past):
| Change | Active | Passive | Why |
|---|---|---|---|
| Object becomes subject | this home | This home | “This home” becomes the subject. |
| Tense kept | built | was built | Was/were + past participle in the same tense: simple past “built” becomes “was built” (singular subject). |
| Agent (by ...) | My grandfather | by my grandfather | The doer becomes “by my grandfather”. The time phrase “in 1930” may stand before or after it. |
| Full sentence | My grandfather built this home in 1930. | This home was built in 1930 by my grandfather. |
Example: Shah Jahan built the Taj Mahal. → The Taj Mahal was built by Shah Jahan.
Why the Other Options are Incorrect?
Option 1: This home is built by my grandfather in 1930. — Incorrect. "is built" is present tense. A past action in 1930 needs "was built".
Option 2: My grandfather in 1930 built this home. — Incorrect. It is still in the active voice. Only the word order has changed.
Option 3: This home is being built by my grandfather. — Incorrect. "is being built" is present continuous, and the year 1930 is dropped.
