Question

As soon as the hostage ran out of the room the terrorists fired at him.

• A. No sooner had the hostage run out of the room than the terrorists fired at him.
• B. No sooner did the hostage run out of the room than the terrorists fired at him.
• C. No sooner did the hostage ran out of the room than the terrorists fired at him.
• D. No sooner did the hostage run out of the room then the terrorists fired at him.

Answer 1

Answer: (A), (B)

The correct options are
A No sooner had the hostage run out of the room than the terrorists fired at him.
B No sooner did the hostage run out of the room than the terrorists fired at him.

'No sooner..than' is used to suggest that one action takes place immediately after another action. When 'no sooner..than' is used at the beginning of the sentences then auxiliary verb goes before the subject. No sooner always introduces the event that occurred first.

The given sentence can be transformed using no sooner..than by beginning the sentence with 'no sooner'' followed by 'than'.

There are two correct options to this question. Options A and B are the correct answers as the auxiliary verbs 'had' and 'did' are before the subject 'the hostage' and tense is also correctly used. Options C and D are grammatically wrong.
