Which of the following options is the most suitable conversion of the following sentence into active voice?
Major breakthroughs in renewable energy have been achieved by scientists in recent decades.
Show answer & explanation
Correct answer: D
Explanation
To convert a sentence from passive to active voice, we follow these steps:
In the passive sentence, "Major breakthroughs" is the receiver of the action (the object), and "scientists" is the doer (the subject).
The original sentence uses the Present Perfect Passive tense ("have been achieved").
The doer ("scientists") becomes the subject, followed by the active form of the verb in the same tense, and then the receiver.
“Have been achieved” in the passive voice gets changed to “have achieved” in the active voice.
Option ‘D’ implements all these changes.
