SSC CGL Voice Questions with Detailed Solutions

The correct passive voice of the given sentence is (d).
The given sentence is an interrogative sentence in the Past Perfect Tense beginning with the helping verb “Had”. In the passive voice of the past perfect, the structure becomes Had + object + been + V3 + by + subject. Therefore “Had the investigation team examined all the suspicious documents?” becomes “Had all the suspicious documents been examined by the investigation team?” The subordinate clause “before the court hearing began” remains unchanged, as it is in the simple past and is not the clause being transformed.
Option (a) shifts the tense to the simple past, option (b) shifts it to the present perfect, and option (c) shifts it to the past continuous — all three change the original time relation.
Structure:
Active voice: Had + Subject + V3 + Object?
Passive Voice: Had + Object + been + V3 + by + Subject?
Example (Active): Had the chef prepared the dessert? → (Passive): Had the dessert been prepared by the chef?

The correct passive voice of the given sentence is (c).
The given sentence is in the Simple Present Tense (“checks”). In the passive voice of the simple present, the object of the active sentence (“the quality of every product”) becomes the subject, the verb takes the form is/am/are + V3, and the original subject is placed after “by”. Since “the quality” is a singular noun, “is checked” is used. The adverb “carefully” is retained before the “by + agent” phrase.
Option (a) uses the present continuous passive (“is being checked”), option (b) uses the present perfect passive (“has been checked”) and option (d) uses the simple past passive (“was checked”) — none of these matches the simple present tense of the active sentence.
Structure:
Active voice: Subject + V1/V5 + Object + (adverb)
Passive Voice: Object + is/am/are + V3 + (adverb) + by + Subject
Example (Active): The postman delivers the letters daily. → (Passive): The letters are delivered daily by the postman.

The correct active voice of the given sentence is (c) The receptionist pleased the visitor.
In the given passive sentence, ‘the visitor’ is the receiver of the action and ‘the receptionist’ is the doer (agent). To convert a passive sentence into the active voice, the agent is made the subject, the auxiliary ‘was’ is removed, and the past participle ‘pleased’ is used as the finite past-tense verb, while the original subject becomes the object. Since the passive is in the Simple Past (‘was pleased’), the active must also be in the simple past — ‘pleased’. Option (a) reverses the doer and receiver, option (b) merely repeats a passive structure, and option (d) shifts the tense to the present.
Structure:
Active voice: Subject (agent) + V2 + Object
Passive Voice: Object + was/were + V3 + with/by + Subject
Information booster: Verbs of emotion such as please, satisfy, surprise, disappoint and annoy often take ‘ with’ instead of ‘by’ in the passive when a state of feeling is described — ‘pleased with’, ‘satisfied with’, ‘disappointed with’.

The correct passive voice of the given sentence is (d) The budget proposal was approved by the manager.
The active sentence is in the Simple Past tense (‘approved’). In the passive, the object ‘the budget proposal’ becomes the subject, the auxiliary ‘was’ is used because the new subject is singular, the main verb takes its third form ‘approved’, and the original subject is introduced by ‘by’. Option (a) wrongly uses the present participle ‘approving’, option (b) changes the object to ‘the budget’ and omits ‘proposal’, and option (c) makes the subject plural and drops the essential preposition ‘by’.
Structure:
Active voice: Subject + V2 + Object
Passive Voice: Object + was/were + V3 + by + Subject

The correct passive voice of the given sentence is (d) The broken roads have not been repaired by the authorities for months.
The active sentence is in the Present Perfect tense (‘have not repaired’), so the passive must also remain in the present perfect. In the passive, the object ‘the broken roads’ becomes the subject, the auxiliary ‘have/has’ is retained according to the new subject, ‘been’ is inserted, and the main verb is used in its third form ‘repaired’. The negative word ‘not’ is placed immediately after ‘have’. The agent ‘the authorities’ is introduced with ‘by’. Option (a) shifts to simple past, option (b) to simple present and option (c) to past perfect, so all three change the tense wrongly.
Structure:
Active voice: Subject + have/has + not + V3 + Object
Passive Voice: Object + have/has + not + been + V3 + by + Subject

The correct passive voice of the given sentence is (b).
Structure:
· Active voice: Subject + modal (should) + not + V₁ + object
· Passive voice: Object + modal (should) + not + be + V₃ (+ by + agent, if required)
Two rules decide this question. First, with a modal auxiliary, the passive is formed as modal + be + V₃ — hence “should not be criticised”. Second, when the subject is an indefinite pronoun such as one, people, somebody, they used generally, the agent is omitted in the passive, because it carries no information.
Option (a) retains the redundant agent “by one”; option (c) replaces should with must, which strengthens the obligation and changes the meaning; option (d) is the passive of an imperative sentence, whereas the original is assertive.

The correct passive voice of the given sentence is (a).
The sentence has two clauses, and both must be converted while their original tense relationship is preserved.
Structure:
· Active voice: Subject + had + V₃ + object (Past Perfect)
· Passive voice: Object + had been + V₃ + by + agent
Clause 1 is in the Past Perfect (“had demolished”) → “ had been demolished”.
Clause 2 is in the Simple Past (“delivered”) → “ was delivered” (Simple Past passive: was/were + V₃).
Option (b) wrongly shifts the first clause to the Present Perfect; option (c) wrongly reduces the earlier action to the Simple Past while elevating the later one to the Past Perfect, which reverses the sequence of events; option (d) leaves the second clause in the active voice and also alters its tense.
Information Booster: When a sentence contains two actions in the past, the earlier action takes the Past Perfect and the later action takes the Simple Past. Conversion to the passive must never disturb this order — if it does, the meaning of “before/after” is destroyed.

The correct active voice of the given sentence is (a).
Structure:
· Passive voice: It + has been + V₃ + that-clause / Object + is + V₃ + by + agent
· Active voice: Agent (subject) + has + V₃ + object
The impersonal passive “It has been decided by the board” becomes “ The board has decided”. The sub-clause “will be issued” becomes “ it will issue”, and “is completed by the registry” becomes “ the registry completes”.
Note the time clause: after after, the Simple Present is used for a future action — hence “completes”, not “will complete”.
Option (b) shifts the main verb to the Past Perfect without cause; option (c) retains a passive in the final clause and alters its tense; option (d) moves the entire sentence into the past, which the original does not warrant.
Information Booster: Conjunctions of time such as after, before, when, until, as soon as never take a future tense in the clause they introduce, even when the main clause is future: I will call you after I reach home (not “after I will reach”).

The correct active voice of the given sentence is (b) None of the witnesses spoke a word during the trial.
The passive agent “by any of the witnesses” becomes the active subject, and since the sentence is negative (“Not a word was spoken”), the negative is carried into the subject as “None of the witnesses”. The tense remains Simple Past, so “spoke” (V₂) is used.
Structure:
Active voice: Subject + V₂ + Object
Passive Voice: Object + was/were + V₃ + by + Subject
Example: Nothing was said by anyone. → No one said anything.
Explain why other options are incorrect: (a) “Any… did not” is non-standard English; the correct form is “None”; (c) and (d) change the tense to past perfect and present perfect respectively.

The correct active voice of the given sentence is (a) The police recovered the stolen painting.
The agent “the police” becomes the subject and the passive subject “the stolen painting” becomes the object. Since the passive is in the Simple Past Tense (“was recovered”), the active takes V₂ — “recovered”.
Structure:
Active voice: Subject + V₂ + Object
Passive Voice: Object + was/were + V₃ + by + Subject
Example: The letter was written by Mohan. → Mohan wrote the letter.
Explain why other options are incorrect: (b) uses simple present; (c) uses past perfect, which is not the original tense; (d) reverses subject and object, destroying the meaning.

The correct active voice of the given sentence is (a) The teacher makes the students clean the classroom every day.
In the passive, causative verbs like “make” are followed by a to-infinitive (“are made to clean”), but in the active voice the “to” is dropped and the bare infinitive is used (“makes the students clean”). Since the doer is not mentioned in the passive, a logical agent (“the teacher”) is supplied.
Structure:
Active voice: Subject + make/makes + Object + V₁ (bare infinitive) + …
Passive Voice: Object + is/are made + to + V₁ + …
Example: The manager made him resign. → He was made to resign.
Explain why other options are incorrect: (b) and (d) drop the causative idea altogether; (c) is another passive sentence, not an active one.

The correct passive voice of the given sentence is (d) It is said that the destitutes had been helped at the time of need by the outlaw.
The reporting verb “say” is in the Simple Present Tense, so its passive must remain in the present: “It is said that…”. The subordinate clause is in the Past Perfect Tense (“had helped”), whose passive is “had been + V₃” → “had been helped”.
Structure:
Active voice: People say that + Subject + had + V₃ + Object
Passive Voice: It is said that + Object + had been + V₃ + by + Subject
Example: People believe that he had cheated. → It is believed that he had cheated / he had been cheated (as per structure).
Explain why other options are incorrect: (a) and (c) wrongly shift the reporting verb to past (“It was said”); (b) uses “had been being helped”, which is not a valid passive form.

The correct active voice of the given sentence is (b) They need to finish this work today.
“Need to be + V₃” is the passive pattern after the verb “need”. In the active voice it becomes “need to + V₁”, with an indefinite subject such as “they/we/one” supplied, while the tense (present) remains unchanged.
Structure:
Active voice: Subject + need(s) + to + V₁ + Object
Passive Voice: Object + need(s) + to be + V₃
Example: The room needs to be cleaned. → They need to clean the room.
Explain why other options are incorrect: (a) omits “to” after the main verb “need”; (c) wrongly shifts the tense to past; (d) removes the modal sense of necessity entirely.

The correct passive voice of the given sentence is (c) The children flying kites in the park were photographed by the visitors.
The sentence is in the Simple Past Tense, whose passive is “was/were + V₃”. The new subject “the children” is plural, so “were photographed” is used, and the modifier “in the park” must stay with “flying kites”.
Structure:
Active voice: Subject + V₂ + Object
Passive Voice: Object + was/were + V₃ + by + Subject
Example: The police arrested the thief. → The thief was arrested by the police.
Explain why other options are incorrect: (a) uses singular “was” with a plural subject; (b) changes “visitors” to singular “visitor” and shifts the phrase “in the park”; (d) wrongly converts the tense to past perfect.

The correct passive voice of the given sentence is (b) The railway electrification will have been completed by next year.
The given sentence is in the Future Perfect Tense. In the passive voice, the object becomes the subject, and the verb takes the form “will have been + V₃”.
Structure:
Active voice: Subject + will have + V₃ + Object
Passive Voice: Object + will have been + V₃ + by + Subject
Here, “the railway electrification” becomes the subject and “completed” (V₃) is used after “will have been”. The agent “by them” is understood and may be dropped.
Example: They will have finished the work. → The work will have been finished (by them).
Explain why other options are incorrect: (a) changes the tense to present perfect; (c) uses the -ing form which is not possible in the perfect passive; (d) omits “been” and is therefore active in form.
