Which of the following options is the most suitable conversion of the following sentence into Passive Voice?
We were rearranging the library when the earthquake occurred.
Show answer & explanation
Correct answer: D
Explanation
The original sentence, "We were rearranging the library when the earthquake occurred," uses the past continuous tense for the main action ("We were rearranging the library"). When converting a past continuous sentence into the passive voice, the structure is "object + was/were + being + past participle of the main verb + by + subject (optional) + remaining part of the sentence".
Option D correctly applies the past continuous passive voice structure.
