In the following question, a sentence has been given in Active/Passive voice. Out of the four alternatives suggested, select the one which best expresses the same sentence in Passive/Active voice.
Two engines are pulling the train up the hill.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. The train is being pulled up the hill by two engines.
Active voice- Subject + is/am/are + V4 + Object
Passive voice- Subject + is/am/are + being+ V3 + by agent
- An object must answer 'what' or 'whom'.
- 'The train' answers 'what' and hence is the object of the active voice which changes into the subject of the passive voice.
- 'Pull' is the main verb which changes into its third form i.e. 'pulled'.
As the chosen option follows the above structure it will be correct.
