Q1. Choose the correct answer from the given options: Why did they pull down the building? (Change the voice)
A Why had been the building pulled down?
B Why did the building been pulled down?
C Why is the building been pulled down?
D Why was the building pulled down? Correct
Explanation
सही उत्तर D है क्योंकि मूल वाक्य साधारण भूतकाल में है। कर्म 'the building' को वाक्य की शुरुआत में लाकर कर्मवाच्य में 'was' के साथ 'pulled down' आता है: 'Why was the building pulled down?' A, B और C में सहायक क्रियाओं का मेल गलत है।
