Question

as soon as she saw them she disappeared (begin no sooner)​

Answer 1

Answer:

No sooner did he see them than he disappeared.

Answer 2

Answer:

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 answers to this question. Options A and B are the correct answers as the auxiliary verb is before the subject 'the moon' and the tense is correctly used. Option C is grammatically wrong. 'Disappeared' should be used in option D thus it is also a wrong option.
