You should not mock the disabled.
Answer:
The disabled should not be mocked.
**Rule**: For sentences with modal verbs (like should, must, can), the passive structure is **Object + modal verb + not + be + V3**. The agent 'by you' can be omitted if the meaning is clear without it.
- **Correct Answer (b)**: The object 'the disabled' becomes the subject. The modal 'should not' is followed by 'be' and the past participle 'mocked'. Omitting 'by you' is common in such general statements.
- **Incorrect Answer (a)**: 'are not to be' is not the standard passive form for the modal 'should'.
- **Incorrect Answer (c)**: 'must not' implies a stronger prohibition than the advice given by 'should not'.
- **Incorrect Answer (d)**: 'need not' suggests a lack of necessity, which changes the meaning from giving advice.

The doctor advised the patient not to eat rice.
Answer:
The patient was advised by the doctor not to eat rice.
**Rule**: For a sentence in the Simple Past Tense, the passive structure is **Object + was/were + V3 + by + Subject**. The infinitive phrase ('not to eat rice') remains unchanged.
- **Correct Answer (a)**: The object 'the patient' becomes the subject. Since it's singular, 'was' is used, followed by the past participle 'advised'. The infinitive phrase 'not to eat rice' correctly follows the main verb.
- **Incorrect Answer (b)**: Adding 'that he should' unnecessarily changes the sentence structure from a simple infinitive to a subordinate clause.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Past Continuous.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Perfect.
66283

Answer:
A new hospital is being built by them near the airport.
**Rule**: For a sentence in the Present Continuous Tense, the passive voice structure is **Object + is/am/are + being + V3 + by + Subject**.
- **Correct Answer (a)**: The object 'a new hospital' becomes the subject. Since it is singular, 'is' is used, followed by 'being' and the past participle 'built'. The agent 'by them' is correctly included.
- **Incorrect Answer (b)**: 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.
66284
Did he remember the date and time?
Answer:
Were the date and time remembered by him?
**Rule**: For an interrogative sentence in the Simple Past Tense starting with 'Did', the passive structure is **Was/Were + object + V3 + by + subject?** The verb must agree with the new subject.
- **Correct Answer (b)**: The object 'the date and time' is a compound subject and thus plural, so it takes the plural verb 'Were'. The past participle 'remembered' is correct.
- **Incorrect Answer (a)**: 'Was' is incorrect because the subject 'the date and time' is plural.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Past Perfect.
66285

Answer:
The car had been repaired by the mechanic.
**Rule**: For a sentence in the Past Perfect Tense, the passive voice structure is **Object + had + been + V3 + by + Subject**.
- **Correct Answer (d)**: The object 'the car' becomes the subject. The verb form 'had been repaired' is the correct passive construction for the Past Perfect Tense.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Simple Present.
66286
The government has banned the use of plastic bags.
Answer:
The use of plastic bags has been banned by the government.
**Rule**: For a sentence in the Present Perfect Tense, the passive voice structure is **Object + has/have + been + V3 + by + Subject**.
- **Correct Answer (b)**: The object 'the use of plastic bags' becomes the subject. Since 'use' is singular, 'has' is used, followed by 'been' and the past participle 'banned'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Past Perfect.
66287
The teacher had not yet checked the papers.
Answer:
The papers had not yet been checked by the teacher.
**Rule**: For a negative sentence in the Past Perfect Tense, the passive structure is **Object + had + not + been + V3**. Adverbs like 'yet' are usually placed after 'not'.
- **Correct Answer (c)**: The object 'the papers' becomes the subject. The verb form 'had not yet been checked' is the correct passive construction and adverb placement.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (d)**: The word order 'yet not' is grammatically incorrect.
66288

Answer:
A new scheme for farmers has been launched by the government.
**Rule**: For a Present Perfect Tense sentence, the passive structure is **Object + has/have + been + V3 + by + Subject**.
- **Correct Answer (a)**: The object 'a new scheme for farmers' becomes the subject. Since it's singular, 'has' is used, followed by 'been' and the past participle 'launched'.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Past Perfect.
66289
He did not obey the orders.
Answer:
The orders were not obeyed by him.
**Rule**: For a negative sentence in the Simple Past Tense, the passive voice structure is **Object + was/were + not + V3 + by + Subject**.
- **Correct Answer (d)**: The object 'the orders' becomes the subject. Since 'orders' is plural, 'were' is used, followed by 'not' and the past participle 'obeyed'.
- **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.
66290
The organization has to help the needy.
Answer:
The needy have to be helped by the organization.
**Rule**: When the active sentence uses 'has to'/'have to', the passive form is **Object + has/have to + be + V3**.
- **Correct Answer (c)**: The object 'the needy' (which is plural) becomes the subject. Since the subject is plural, it takes 'have to be', followed by the past participle 'helped'.
- **Incorrect Answer (a)**: 'have been helped' is the passive of the Present Perfect Tense.
- **Incorrect Answer (b)**: 'had to be' incorrectly changes the tense to the past.
- **Incorrect Answer (d)**: 'are to be' implies a plan, which is a different meaning.
