Which of the following options is the most suitable conversion of the following sentence into active voice?
Several valuable discoveries have been made by scientists in the polar regions.
Show answer & explanation
Correct answer: C
Explanation
Here is why:
To convert a sentence from passive to active voice, you need to match the tense of the original sentence.
Identify the Tense: The original sentence, "Several valuable discoveries have been made...", is in the Present Perfect tense (passive).
Identify the Subject and Object:
Passive Subject: Several valuable discoveries
Agent (who did it): Scientists
Rearrange: In the active voice, the agent (Scientists) becomes the subject. To keep the Present Perfect tense, you use "have made."
Option ‘C’ follows all these changes.
