"The children hardly have problems waking up early for school, _______?"
- do they
- don't they
- have they
- haven't they
I am not sure which is the right tag question, also called Question tag in BrEng.
Am I confident and only asking someone to confirm my statement?
- The children hardly have problems[…], do they?
Am I uncertain and want to know if I am wrong?
- The children hardly have problems […], don't they?
Should I repeat the same verb in the subordinate clause?
- Thee children hardly have problems[…], have they?
Or should the question tag be negative because the statement is positive?
- The children hardly have problems[…], haven't they?
I find question tags very confusing, as each of the four solutions appear to make sense to me.
