Question

Transform the sentence with 'as soon as' to a sentence with 'no sooner than'.
As soon as Eric left the office, his manager entered the building.

• A. No sooner does Eric leave the office than his manager entered the building.
• B. No sooner had Eric left the office than his manager entered the building.
• C. No sooner had Eric left the office than his manager enter the building.
• D. No sooner did Eric left the office than his manager entered the building.

Answer 1

The correct option is B No sooner had Eric left the office than his manager entered the building.

'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'.

Option B is the correct answer as the auxiliary verb 'had' is before the subject 'Eric'. Options A, C, and D are grammatically wrong.
