Who taught her such tricks?
Answer:
By whom was she taught such tricks?
**Rule**: Interrogative sentences in the Simple Past Tense starting with 'Who' are converted to passive voice using **By whom + was/were + object + V3?**
- **Correct Answer (a)**: 'Who' becomes 'By whom'. The object 'her' becomes the subject 'she', which is singular and takes 'was'. The past participle 'taught' is used correctly.
- **Incorrect Answer (b)**: 'were' is incorrect with the singular subject 'she'.
- **Incorrect Answer (c)**: The word order is incorrect, and 'who' should be 'whom' after the preposition 'by'.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Perfect.
66222
One should keep one's promises.
Answer:
Promises should be kept.
**Rule**: When the subject of an active sentence is an indefinite pronoun like 'one', 'someone', or 'people', it is generally omitted in the passive voice. The structure for modals like 'should' is **Object + modal + be + V3**.
- **Correct Answer (a)**: The object 'promises' becomes the subject. 'should be kept' is the correct passive construction. The agent 'by one' is omitted as it is understood from the context of a general truth.
- **Incorrect Answer (b)**: Including 'by one' is grammatically correct but stylistically redundant in this context.
- **Incorrect Answer (c)**: 'them' is an incorrect pronoun to refer back to the singular 'one'.
- **Incorrect Answer (d)**: 'were to be kept' incorrectly changes the modal verb and the tense.
66223
The board has approved the new policy.
Answer:
The new policy has been approved by the board.
**Rule**: For a sentence in the Present Perfect Tense, the passive voice structure is **Object + has/have + been + V3 + by + Subject**.
- **Correct Answer (d)**: The object 'the new policy' becomes the subject. Since it is singular, 'has' is used, followed by 'been' and the past participle 'approved'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Past Perfect.
66224
We must listen to his words.
Answer:
His words must be listened to by us.
**Rule**: For sentences with modal verbs and phrasal verbs (verb + preposition), the passive structure is **Object + modal verb + be + V3 + preposition + by + Subject**.
- **Correct Answer (a)**: The object 'his words' becomes the subject. The modal 'must' is followed by 'be'. The past participle 'listened' is used, and the preposition 'to' is correctly retained.
- **Incorrect Answer (b)**: The preposition 'to' is incorrectly omitted.
- **Incorrect Answer (c)**: 'should' is a different modal and changes the meaning from obligation to advice.
- **Incorrect Answer (d)**: This incorrectly changes the tense and modal structure to Simple Past.
66225
They found him guilty of murder.
Answer:
He was found guilty of murder by them.
**Rule**: For a sentence in the Simple Past Tense, the passive voice structure is **Object + was/were + V3 + by + Subject**. The object complement ('guilty of murder') remains after the verb.
- **Correct Answer (d)**: The object 'him' becomes the subject 'He'. The verb 'was found' is the correct passive form for the Simple Past Tense. The object complement 'guilty of murder' follows, and the agent 'by them' is included.
- **Incorrect Answer (a)**: This is also grammatically correct, but it omits the agent 'by them'. Option (d) is a more complete transformation of the original sentence.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Past Perfect.
66226
Why do you tell a lie?
Answer:
Why is a lie told by you?
**Rule**: For interrogative sentences in the Simple Present Tense starting with a 'Wh-' word, the passive structure is **Wh- word + is/am/are + object + V3 + by + subject?**
- **Correct Answer (a)**: The 'Wh-' word 'Why' remains at the beginning. The object 'a lie' is singular, so 'is' is used. This is followed by the object and the past participle 'told'.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (c)**: This is not in the correct interrogative word order; the verb 'is' should come before the subject 'a lie'.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Continuous.
66227
They will not announce the results before next week.
Answer:
The results will not be announced by them before next week.
**Rule**: To convert a Future Simple Tense sentence to passive voice, the structure is **Object + will/shall + not + be + V3 + by + Subject**.
- **Correct Answer (a)**: The object 'the results' becomes the subject. 'will not be' is the correct passive verb form, followed by the past participle 'announced'. The agent 'by them' is correctly placed at the end.
- **Incorrect Answer (b)**: This option incorrectly uses 'would' instead of 'will', changing the modal verb and the meaning.
- **Incorrect Answer (c)**: This option incorrectly changes the tense to Simple Present Tense.
- **Incorrect Answer (d)**: This option incorrectly changes the tense to Present Perfect Tense.
66228
A great man acknowledged me as a flatterer.
Answer:
I was acknowledged as a flatterer by a great man.
**Rule**: For a sentence in the Simple Past Tense, the passive voice structure is **Object + was/were + V3 + by + Subject**. The complement 'as a flatterer' remains after the verb.
- **Correct Answer (a)**: The object 'me' becomes the subject 'I'. The verb form 'was acknowledged' is correct for the Simple Past. The complement 'as a flatterer' follows the verb.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Past Continuous.
66229

Answer:
Why is such a noise being made by you?
**Rule**: For interrogative sentences in the Present Continuous Tense starting with a 'Wh-' word, the passive structure is **Wh- word + is/am/are + object + being + V3 + by + subject?**
- **Correct Answer (d)**: The 'Wh-' word 'Why' remains at the beginning. The object 'such a noise' is singular, so 'is' is used. This is followed by the object, 'being', and the past participle 'made'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Past Continuous.

**Rule**: For a Present Continuous Tense sentence, the passive structure is **Object + is/am/are + being + V3 + by + Subject**.
