Question

None of the workmen arrived, ___________?

• A. do they?
• B. don't they?
• C. did they?
• D. didn't they?

Answer 1

Answer:

C. did they?

• The word “none” indicates negative. The main clause is "None of the workmen arrived" (negative), so the tag should be positive. So the verb in the question tag will be a positive form (no use of “not”) of the past-tense auxiliary “did”
• do they? - This is incorrect because the auxiliary verb "do" is used for positive statements, not for negative statements like "None of the workmen arrived."
• don't they? - This is incorrect because "don't" is a contraction for "do not," which is used for positive statements and is not appropriate for the negative context here.
• didn't they? - This is incorrect because "didn't" is used for negative sentences, but the original sentence is already negative, so the tag question should be positive.
