Question

Change the given sentence to passive voice.

Our English teacher was delivering a lecture. [Advanced]

• A. A lecture is being delivered by our English teacher.
• B. A lecture is delivered by our English teacher.
• C. A lecture had been delivered by our English teacher.
  
• D. A lecture was being delivered by our English teacher.

Answer 1

The correct option is D A lecture was being delivered by our English teacher.

The sentence uses the words 'was delivering' which indicates that it is in the past continuous tense. The passive form of the sentence must maintain this tense. Option A) contains the words 'is being delivered' which is in the present continuous tense. Hence, it is incorrect. Option B) is incorrect because it has 'is delivered' which is in the past tense. Option C) indicates that the lecture is complete and not an ongoing process as is indicated by the original sentence.

So, the most appropriate answer is D) A lecture was being delivered by our English teacher.
