Let them do their work.
Answer:
Let their work be done by them.
**Rule**: An active sentence beginning with 'Let' followed by an object and a bare infinitive has the passive structure: **Let + new subject (direct object) + be + V3 + by + new object (original object)**.
- **Correct Answer (c)**: The direct object 'their work' becomes the new subject after 'Let'. This is followed by 'be' and the past participle 'done'. The original object 'them' becomes the agent 'by them'.
- **Incorrect Answer (a)**: This omits the agent 'by them', making the sentence less specific.
- **Incorrect Answer (b)**: 'Should' changes the imperative mood to one of suggestion.
- **Incorrect Answer (d)**: This changes the structure and meaning entirely, introducing the concept of permission.

Who is going to answer the question?
Answer:
By whom is the question going to be answered?
**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 (d)**: 'Who' changes to 'By whom'. The object 'the question' is singular, so 'is' is used, followed by the object and the correct passive structure 'going to be answered'.
- **Incorrect Answer (a)**: This changes the structure to the 'will' future.
- **Incorrect Answer (b)**: 'who' is the incorrect case; 'whom' is required after the preposition 'By'.
- **Incorrect Answer (c)**: This word order is not standard for formal interrogative sentences.

Answer:
A gourmet meal was being prepared by the chef.
**Rule**: For a sentence in the Past Continuous Tense, the passive voice structure is **Object + was/were + being + V3 + by + Subject**.
- **Correct Answer (a)**: The object 'a gourmet meal' becomes the subject. Since it's singular, 'was' is used, followed by 'being' and the past participle 'prepared'.
- **Incorrect Answer (b)**: 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.

Let me finish this task.
Answer:
Let this task be finished by me.
**Rule**: An active sentence beginning with 'Let' followed by an object and a bare infinitive has the passive structure: **Let + new subject (direct object) + be + V3 + by + new object (original object)**.
- **Correct Answer (a)**: The direct object 'this task' becomes the new subject after 'Let'. This is followed by 'be' and the past participle 'finished'. The original object 'me' becomes the agent 'by me'.
- **Incorrect Answer (b)**: 'Should' changes the imperative mood to one of suggestion or obligation.
- **Incorrect Answer (c)**: This omits the agent 'by me', making the sentence less precise than the original.
- **Incorrect Answer (d)**: This changes the structure and meaning entirely, introducing the idea of permission.
66485

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

- **Incorrect Answer (a)**: This incorrectly changes the tense to Past Continuous.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Present Perfect.

They were laughing at the clown.
Answer:
The clown was being laughed at by them.
**Rule**: When a phrasal verb (verb + preposition) is used in the Past Continuous Tense, the passive structure is **Object + was/were + being + V3 + preposition + by + Subject**.
- **Correct Answer (b)**: The object 'the clown' becomes the subject. The passive verb form 'was being laughed at' correctly keeps the preposition 'at' with the verb.
- **Incorrect Answer (a)**: This incorrectly omits the preposition 'at'.
- **Incorrect Answer (c)**: This uses the wrong preposition 'at' instead of 'by' to introduce the agent.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Continuous.
66487
He will have to pay the fine.
Answer:
The fine will have to be paid by him.
**Rule**: When the active sentence uses 'will have to', the passive form is **Object + will have to + be + V3**.
- **Correct Answer (b)**: The object 'the fine' becomes the subject. The structure 'will have to be paid' is the correct passive form for the future obligation.
- **Incorrect Answer (a)**: 'will have been paid' is the passive of the Future Perfect Tense.
- **Incorrect Answer (c)**: 'would' is an incorrect modal change.
- **Incorrect Answer (d)**: 'is to be' incorrectly changes the tense and meaning to a present plan.
66488
The company has to update its policies.
Answer:
Its policies have to be updated by the company.
**Rule**: When the active sentence uses 'has to'/'have to', the passive form is **Object + has/have to + be + V3**.
- **Correct Answer (b)**: The object 'its policies' becomes the subject. Since 'policies' is plural, it takes 'have to be', followed by the past participle 'updated'.
- **Incorrect Answer (a)**: 'have been updated' is the passive of the Present Perfect Tense.
- **Incorrect Answer (c)**: 'had to be' incorrectly changes the tense to the past.
- **Incorrect Answer (d)**: 'are to be' implies a plan, not the necessity of 'have to'.
66489

The car was not being chased by the dog.
**Rule**: For a negative sentence in the Past Continuous Tense, the passive structure is **Object + was/were + not + being + V3 + by + Subject**.
- **Correct Answer (a)**: The object 'the car' becomes the subject. The passive verb form 'was not being chased' correctly reflects the negative Past Continuous tense.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Continuous.

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