The company has to check all the details.
Answer:
All the details have to be checked by the company.
**Rule**: When the active sentence uses 'has to'/'have to', the passive form is **Object + has/have to + be + V3**. The choice between 'has' and 'have' depends on the new subject.
- **Correct Answer (d)**: The object 'all the details' becomes the subject. Since 'details' is plural, it takes 'have to be', followed by the past participle 'checked'.
- **Incorrect Answer (a)**: 'have been checked' is the passive of the Present Perfect Tense.
- **Incorrect Answer (b)**: 'are to be' implies a plan, not the necessity of 'have to'.
- **Incorrect Answer (c)**: 'had to be' incorrectly changes the tense to the past.
262
Which route did you take?
Answer:
Which route was taken by you?
**Rule**: For an interrogative sentence in the Simple Past Tense starting with 'Which', the passive structure is **Which + noun + was/were + V3 + by + subject?**
- **Correct Answer (c)**: 'Which route' remains at the beginning. As 'route' is singular, it is followed by 'was' and the past participle 'taken'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Past Continuous.

Answer:
Several trees were uprooted by the storm.
**Rule**: For a sentence in the Simple Past Tense, the passive voice structure is **Object + was/were + V3 + by + Subject**.
- **Correct Answer (b)**: The object 'several trees' becomes the subject. Since 'trees' is plural, 'were' is used, followed by the past participle 'uprooted'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Past Continuous.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Perfect.
264
Did the board approve your proposal?
Answer:
Was your proposal approved by the board?
**Rule**: For an interrogative sentence in the Simple Past Tense starting with 'Did', the passive structure is **Was/Were + object + V3 + by + subject?**
- **Correct Answer (c)**: The object 'your proposal' is singular, so the sentence starts with 'Was'. This is followed by the object and the past participle 'approved'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (d)**: This is not in the correct interrogative word order; the auxiliary verb 'Was' must come before the subject.
265
The noise from the construction site is bothering me.
Answer:
I am being bothered by the noise from the construction site.
**Rule**: For a Present Continuous Tense sentence, the passive structure is **Object + is/am/are + being + V3 + by + Subject**.
- **Correct Answer (d)**: The object 'me' becomes the subject 'I'. The verb form 'am being bothered' is correct for the Present Continuous passive for the first person singular.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Past Continuous.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Present Perfect.
266
Who is designing the new bridge?
Answer:
By whom is the new bridge being designed?
**Rule**: Interrogative sentences in the Present Continuous Tense starting with 'Who' are converted to passive voice using **By whom + is/am/are + object + being + V3?**
- **Correct Answer (b)**: 'Who' becomes 'By whom'. The object 'the new bridge' is singular, so 'is' is used, followed by the object, 'being', and the past participle 'designed'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Past Continuous.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Simple Present.

Answer:
The students' proposal was accepted by the principal.
**Rule**: For a sentence in the Simple Past Tense, the passive voice structure is **Object + was/were + V3 + by + Subject**.
- **Correct Answer (c)**: The object 'the students' proposal' becomes the subject. Since 'proposal' is singular, 'was' is used, followed by the past participle 'accepted'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Past Continuous.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Perfect.
268
They were watching a movie when the power went out.
Answer:
A movie was being watched when the power went out.
**Rule**: In a complex sentence, only the clause with a transitive verb and object is changed to passive. The main clause 'They were watching a movie' (Past Continuous) is passivized, while the subordinate clause remains unchanged. The agent 'by them' can be omitted.
- **Correct Answer (b)**: The object 'a movie' becomes the subject. The verb form 'was being watched' is the correct passive for the Past Continuous. The subordinate clause 'when the power went out' is correctly placed at the end.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Continuous.
269
Why did they refuse him admission?
Answer:
Both a and c are correct.
**Rule**: For an interrogative sentence in the Simple Past with two objects (indirect 'him' and direct 'admission'), either can become the subject in the passive form. The structure is **Wh- word + was/were + object + V3?**
- **Correct Answer (d)**: Both (a) and (c) are correct passive transformations.
- In (a), the indirect object 'him' becomes the subject 'he'. The verb is 'was refused'.
- In (c), the direct object 'admission' becomes the subject. The verb is 'was refused', and the indirect object 'him' is preceded by 'to'.
- **Incorrect Answer (a)**: This is correct, but (c) is also correct.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (c)**: This is correct, but (a) is also correct.

- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Perfect.
