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.
I could not find the book.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. The book could not be found by me.
- An object must answer 'what' or 'whom'.
- 'The book' answers 'what' and hence is the object of the active voice which changes into the subject of the passive voice.
- 'Find' is the main verb which changes into its third form i.e. 'found'.
- 'A modal remains as it is hence 'could' does not change.
As the chosen option follows the above structure it will be correct.
