Question

Choose the correct passive voice of the sentence: "The teacher explained the lesson."

• A. The lesson explains the teacher.
• B. The lesson was explained by the teacher.
• C. The teacher was explained by the lesson.
• D. The lesson is explained by the teacher.

Hint:

Always match the tense of the auxiliary verb ('to be') in the passive voice to the tense of the main verb in the active voice. Since 'explained' is Simple Past, we use 'was explained'.

Answer 1

The Correct Option is B

The active sentence is: "The teacher (Subject) explained (Verb: Simple Past) the lesson (Object)."
To convert to passive voice, the object becomes the subject: "The lesson".
The verb tense (Simple Past) changes to the passive structure: was/were + past participle.
"The lesson was explained".
The original subject becomes the agent: "by the teacher".
The correct passive sentence is: "The lesson was explained by the teacher."
