Change the following sentence into the Active form.
The groundbreaking quantum theory should not have been dismissed as mere speculation by the scientific community.
Show answer & explanation
Correct answer: B
Explanation
To change the sentence from passive voice to active voice, the subject performing the action ("the scientific community") must be placed before the verb, and the object receiving the action ("the groundbreaking quantum theory") must be placed after the verb. Additionally, the verb phrase "should not have been dismissed" (passive) is changed to "should not have dismissed" (active) to maintain the past perfect tense.
