Active and Passive Voice

Option D correctly converts the active sentence into passive voice using the past simple tense: 'They broke up the table' becomes 'The table was broken up by them.' The other options are grammatically incorrect or use wrong tenses.

The sentence is in the passive voice, requiring the past participle form of the verb 'steal,' which is 'stolen.' Therefore, 'The ring was stolen by thieves.' is correct.

The sentence 'The baby has lost her doll' is in the present perfect tense. The correct passive voice form is 'Her doll has been lost by the baby,' which maintains the present perfect tense and correctly uses the passive structure.

The passive voice of 'She will build this house' is 'This house will be built by her' because the future simple tense 'will build' changes to 'will be built' in passive form, and the object 'this house' becomes the subject.

Option C correctly uses the passive voice to express that 'the fight was not given up by him,' which accurately reflects the original active sentence meaning. The other options are grammatically incorrect or awkward in passive construction.

Option B is the correct passive voice form of the sentence, using the past tense 'was upbraided' to match the original meaning. The other options contain grammatical errors or incorrect verb forms.

Option D is grammatically correct because it uses the correct passive form 'should be avoided' and includes the article 'a' before 'good health,' making the sentence clear and proper.

Option C is the grammatically correct passive construction of the sentence, using 'was realized' to indicate the past realization. The other options contain grammatical errors such as incorrect verb forms, wrong word usage ('quiet' instead of 'quite'), or misspellings ('ere' instead of 'were').

The correct sentence is 'Afridi plays the harmonium and the sitar is played by him also.' This is because the second part of the sentence is in passive voice and requires the object pronoun 'him' after 'played by' to be grammatically correct. Option C 'Played by him' correctly completes the sentence. Option A 'Played' is incomplete and grammatically incorrect in this context. Option B 'Played by he' is incorrect because 'he' is a subject pronoun and cannot be used as the object of the preposition 'by'. Option D 'None of these' is incorrect as option C is the correct choice.

Option B correctly converts the active sentence into the passive voice, maintaining the present simple tense and the original meaning. It uses the correct passive structure: 'I am greeted cheerfully by them every morning.'

Option C correctly changes the active sentence 'You must obey your parents' into the passive voice as 'Your parents must be obeyed by you.' This is the proper passive construction with 'must' + 'be' + past participle.

Option B correctly uses the gerund phrase 'being taken' to express the passive form that matches the original sentence's meaning. It is the grammatically correct and natural way to convey the idea in passive voice. Other options are either ungrammatical or awkward.

The sentence 'I take exercise daily' is in the simple present tense, indicating a habitual action. The correct passive voice form for a simple present tense active sentence is formed using 'is/am/are + past participle'. Therefore, the correct passive sentence is 'Exercise is taken daily by me.' Option C, 'Exercise is being taken daily by me,' is present continuous passive, which implies an action happening right now, not a habitual action. Options A and D are grammatically incorrect due to subject-verb agreement and incorrect verb forms.

Option A correctly converts the active sentence 'She will invite me' into the passive voice as 'I shall be invited by her,' using the proper future passive structure. The other options contain grammatical errors in verb forms or auxiliary usage.

Option D correctly forms the passive voice question equivalent of "Did you visit a zoo?" by using the past simple passive structure "Was a zoo visited by you?". The other options contain incorrect verb forms or auxiliary verbs, making them grammatically incorrect.

Option D, 'Will the cake have been baked by my mother?' is the correct passive voice form of the future perfect tense, matching the active voice question 'Will my mother have baked cake?'. The other options contain grammatical errors or incorrect tense usage.

Option B correctly transforms the active sentence into the passive voice with proper grammar: 'The lecture probably won’t be attended by them.' It maintains the meaning and tense accurately.

Option D is the correct passive voice transformation of the sentence with proper grammar and tense: 'A car was being driven by him, when the accident occurred.' The other options contain grammatical errors or incorrect tense usage.

Option A correctly transforms the active question into a grammatically correct passive voice question using the present continuous tense: 'Is a match being played against our team by them?'. The other options contain grammatical errors in verb form or tense.

Option D, "By whom is this mess being created?", is the correct passive voice question form corresponding to the active voice question "Who is creating this mess?". It correctly uses the passive structure with "is being created" and the formal interrogative "By whom".

Option B is the grammatically correct passive voice question form, using 'are' to agree with the plural noun 'duties' and the correct past participle 'neglected'.

Option A, "Have a rest been taken by you?", is the grammatically correct passive voice form corresponding to the active voice question "Have you taken a rest?". It correctly uses the present perfect passive structure with "have been taken". Although the passive voice of "take a rest" is grammatically possible, it is rarely used and sounds unnatural in everyday English. The other options are grammatically incorrect.

Option C, 'By whom a car was designed?' is the correct passive voice question form corresponding to 'Who designed a car?'. It correctly uses the past simple passive structure with 'was designed'. The other options are grammatically incorrect or use inappropriate tense/aspect.

Option D is the correct passive voice form of the question. It uses the correct auxiliary verb 'was' to agree with the singular subject 'the best part' and the past participle 'wasted'. The other options have incorrect word order or verb forms.

Option C, "Why is a lie told by you?", is the correct passive voice form of the question "Why do you tell a lie?". It correctly uses the passive structure with the verb "is" and past participle "told".
