66501
Someone must have taken the file from my desk.
Answer:
The file must have been taken from my desk.
**Rule**: For sentences with past modals (modal + have + V3), the passive structure is **Object + modal + have been + V3**. The indefinite subject 'someone' is omitted.
- **Correct Answer (c)**: The object 'the file' becomes the subject. The past modal passive form 'must have been taken' is the correct construction. The agent 'by someone' is correctly omitted.
- **Incorrect Answer (a)**: 'must be taken' is the passive form for a present modal ('must take'), not a past modal.
- **Incorrect Answer (b)**: This changes the modal structure entirely, altering the meaning from deduction to past necessity.
- **Incorrect Answer (d)**: Using 'should' changes the meaning from a strong deduction to a recommendation about a past event.
66502
She showed me the new design.
Answer:
I was shown the new design by her.
**Rule**: For a Simple Past Tense sentence with two objects (indirect 'me' and direct 'the new design'), either can become the subject of the passive sentence.
- **Correct Answer (b)**: The indirect object 'me' becomes the subject 'I'. The verb form 'was shown' is correct for the Simple Past Tense, and the direct object 'the new design' follows.
- **Incorrect Answer (a)**: The past participle of 'show' is 'shown', not 'showed'.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Simple Present.
66503
The artist is carving a beautiful sculpture.
Answer:
A beautiful sculpture is being carved by the artist.
**Rule**: For a Present Continuous Tense sentence, the passive structure is **Object + is/am/are + being + V3 + by + Subject**.
- **Correct Answer (d)**: The object 'a beautiful sculpture' becomes the subject. Since it is singular, 'is' is used, followed by 'being' and the past participle 'carved'.
- **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.
66504
Nobody was listening to the speech.
Answer:
The speech was not being listened to.
**Rule**: A negative sentence in the Past Continuous Tense with a phrasal verb is converted to passive using **Object + was/were + not + being + V3 + preposition**. The negative idea from 'Nobody' is transferred to the verb.
- **Correct Answer (b)**: The object 'the speech' becomes the subject. The passive verb 'was not being listened to' correctly reflects the negative meaning, the Past Continuous tense, and retains the preposition 'to'. The agent is correctly omitted.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Present Continuous.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Perfect.
66505
Someone had locked the gate.
Answer:
The gate had been locked.
**Rule**: For a Past Perfect Tense sentence, the passive structure is **Object + had + been + V3**. The indefinite subject 'someone' is omitted.
- **Correct Answer (c)**: The object 'the gate' becomes the subject. The verb form 'had been locked' is the correct passive construction for the Past Perfect Tense. The agent 'by someone' is correctly omitted.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Simple Present.
66506
Who broke the window?
Answer:
By whom was the window broken?
**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 'the window' is singular, so 'was' is used, followed by the past participle 'broken'.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (d)**: The word order is incorrect for a question, and 'who' should be 'whom' after a preposition.
66507
The team was not playing well.
Answer:
The game was not being played well by the team.
**Rule**: Intransitive verbs (like 'play well' without a direct object) cannot be made passive in the usual way. To make it passive, an implied object must be introduced.
- **Correct Answer (a)**: The implied object 'the game' is introduced as the subject. The verb form 'was not being played' is the correct passive for the negative Past Continuous. The adverb 'well' is correctly placed.
- **Incorrect Answer (b)**: 'Well' is an adverb and cannot be the subject of the sentence.
- **Incorrect Answer (c)**: This structure is grammatically incorrect.
- **Incorrect Answer (d)**: Using the introductory 'It' is possible but less direct and clear than option (a).
66508
The artists were rehearsing the final act.
Answer:
The final act was being rehearsed by the artists.
**Rule**: For a sentence in the Past Continuous Tense, the passive voice structure is **Object + was/were + being + V3 + by + Subject**.
- **Correct Answer (b)**: The object 'the final act' becomes the subject. Since it's singular, 'was' is used, followed by 'being' and the past participle 'rehearsed'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Present Continuous.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Simple Past.
66509
The detective did not solve the mystery.
Answer:
The mystery was not solved by the detective.
**Rule**: For a negative sentence in the Simple Past Tense, the passive structure is **Object + was/were + not + V3 + by + Subject**.
- **Correct Answer (a)**: The object 'the mystery' becomes the subject. The verb form 'was not solved' is the correct passive construction for a negative sentence in the Simple Past Tense.
- **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.
66510
Who is going to arrange the meeting?
Answer:
By whom is the meeting going to be arranged?
**Rule**: For an interrogative sentence with the 'be going to' future form starting with 'Who', the passive structure is **By whom + is/am/are + object + going to be + V3?**
- **Correct Answer (c)**: 'Who' changes to 'By whom'. The object 'the meeting' is singular, so 'is' is used, followed by the object and the correct passive structure 'going to be arranged'. The word order is correct for a question.
- **Incorrect Answer (a)**: This changes the structure from 'going to' future to 'will' future.
- **Incorrect Answer (b)**: The word order is incorrect for an interrogative sentence.
- **Incorrect Answer (d)**: 'who' is the incorrect case; 'whom' is required after the preposition 'By'.
