Active & Passive Voice — Set 10

Correct Answer: B. By whom can this equation be solved?

Modal Interrogative Passive with 'who': 'By whom' goes to the front. 'Who can solve' → 'By whom can this equation be solved?' Structure: By whom + modal + subject + be + past participle? 'Solve' → 'solved'. Inverted question word order is maintained.

Correct Answer: A. When was the letter posted by her?

WH-question Passive (Simple Past): 'When' is retained at the front. 'Did she post' → Simple Past → 'was posted'. Full form: 'When was the letter posted by her?' Structure: When + was/were + passive subject + past participle + by + agent? Question mark is kept.

Correct Answer: A. Where was the treasure found by them?

WH-question Passive: 'Where' is retained. 'Did they find' → Simple Past Passive 'was found'. 'Treasure' (singular) → 'was'. 'They' → 'by them'. Full form: 'Where was the treasure found by them?' Option C is incorrect because inverted word order is required in questions.

Correct Answer: A. Let this chapter be read carefully.

Imperative Passive = Let + object + be + past participle + adverb. 'Read this chapter carefully' → 'Let this chapter be read carefully.' 'Read' past participle is 'read' (same spelling, different pronunciation). 'Carefully' is retained after 'read'. Option D is wrong as 'be' is missing.

Correct Answer: C. Let this letter be posted at once.

Imperative Passive = Let + object + be + past participle + adverb. 'Post this letter at once' → 'Let this letter be posted at once.' 'Post' → 'posted'. Time adverb 'at once' is retained. The standard imperative passive construction uses 'Let...be + past participle'.

Correct Answer: A. Were you helped by him?

Interrogative Simple Past Passive: 'Did he help you?' → 'Were you helped by him?' 'You' is always used with 'were' (never 'was'). 'Did help' → Simple Past → 'were helped'. 'He' → 'by him'. Question mark is retained. 'Were' not 'was' with 'you'.

Correct Answer: A. Must the meeting be attended by us?

Interrogative Modal Passive: The modal 'must' stays at the front (inverted). 'Must we attend' → 'Must the meeting be attended by us?' Structure: Must + subject + be + past participle + by agent? Modal 'must' does not change to 'should' or any other modal.

Correct Answer: A. How was the situation handled by them?

WH-question Passive (How): 'How' is retained at the start. 'Did they handle' → Simple Past → 'was handled'. 'Situation' (singular) → 'was'. 'They' → 'by them'. Full passive: 'How was the situation handled by them?' Inverted question structure is maintained.

Correct Answer: B. Let time not be wasted.

Negative Imperative Passive = Let + object + not + be + past participle. 'Do not waste time' → 'Let time not be wasted.' 'Not' comes after the passive subject (time). Option D is incorrect word order. 'Waste' → 'wasted'. Standard pattern: Let + subject + not + be + past participle.

Correct Answer: A. Could the match have been won by her?

Modal Perfect Interrogative Passive: Modal stays at front (inverted). 'Could she have won' → 'Could the match have been won by her?' Structure: Could + subject + have + been + past participle + by agent? This is a perfect modal in interrogative passive form.
