Which sentence correctly turns 'When does the workshop close?' into an indirect request?
Could you tell me when does the workshop close?
Could you tell me when the workshop closes?✓Correct answer
Could you tell me when closes the workshop?
Could you tell me when the workshop does close?
Explanation
The indirect version retains the wh-word but changes the inner clause to the workshop closes, with no does. A question mark may end the whole request, but it does not license direct-question order inside the clause.
