Which of the following options is the most suitable conversion of the following sentence into active voice?
An elaborate report on climate change is being prepared by the scientists at the institute for the upcoming conference.
Show answer & explanation
Correct answer: B
Explanation
Correct Answer
The scientists at the institute are preparing an elaborate report on climate change for the upcoming conference.
Explanation
The given sentence is in the Present Continuous Passive Voice. To convert it into the active voice, the agent "the scientists at the institute" becomes the subject, and the passive verb "is being prepared" changes to the active form "are preparing." The object "an elaborate report on climate change" remains unchanged, and the tense is preserved.
The other options are incorrect. "Prepare" changes the tense to the Simple Present. "Have prepared" changes it to the Present Perfect. "Will prepare" changes it to the Simple Future, so none of these correctly preserve the original tense.
Key Point
The active voice of a Present Continuous Passive sentence follows the structure: Subject + am/is/are + verb (-ing) + object. While changing the voice, always maintain the original tense and make the doer of the action the subject of the sentence.
