Change the following from active to passive:
Scientists are developing a new vaccine to combat the rapidly mutating virus.
Show answer & explanation
Correct answer: A
Explanation
Correct Answer:-
A new vaccine is being developed by scientists to combat the rapidly mutating virus.
Explanation:-
Identify Tense: The active sentence uses the Present Continuous tense (are developing).
Passive Voice Formula: For Present Continuous, the structure is is/am/are + being + past participle (V3).
Subject-Object Swap: The active object (A new vaccine) becomes the new singular passive subject, which takes is being developed.
Key Points
Core Definition: Passive voice transitions focused attention from the subject performing the action to the direct object receiving the action.
Grammatical Role: Present Continuous Active (is/am/are + V-ing) must always map to Present Continuous Passive (is/am/are + being + V3) to preserve temporal consistency.
