Voice — Passive to Active conversion MCQ — 15 Practice Questions with Answers

Explanation

In passive-to-active conversion, the tense and aspect must be retained. The cue "were being checked" is past continuous passive, showing an action in progress at noon. With the singular agent "the supervisor" as the active subject, the verb must be "was checking". Option B uses simple past "checked", so it is the only incorrect conversion.

Explanation

Rule: The present continuous passive pattern 'is/am/are being + past participle' changes to 'is/am/are + verb-ing' in active voice. Cue: 'are being checked by the supervisor' shows present continuous passive, and 'the supervisor' is the singular agent. Therefore, only 'The supervisor is checking the files' preserves the tense, subject-verb agreement, and meaning.

Explanation

In passive-to-active conversion, the by-agent becomes the active subject, the passive subject becomes the active object, and the tense must be preserved. The cue is "was issued by the board": "was issued" is simple past passive and "the board" is the agent. Therefore, the only correct active form is "The board issued the notice."

Explanation

Rule: An imperative passive sentence in the pattern 'Let + object + be + past participle' is commonly changed into an active command with the base verb. Cue: 'Let the register be kept on the table' has the object 'the register' and the action 'keep'. Therefore, the active form is 'Keep the register on the table'; the assertion is true, the reason is true, and the reason correctly explains the assertion.

Explanation

In a passive imperative with "Let," the pattern "Let + object + be + past participle + by + agent" changes to "Let + agent + base verb + object." The cues are "the files" as the object, "be arranged" as the passive verb group, and "by the assistant" as the agent. Therefore, "Let the files be arranged by the assistant" becomes "Let the assistant arrange the files." Both A and R are true, and R correctly explains A.
