I know that indefinite pronouns like none and each take singular verbs, but what about their question tags?
None of the boys has passed the test, ________?
Each of the girls was given a prize, _______?
What are the question tags for these two sentences? Should the question tag’s verb be in the singular like the subject or plural because we’re talking about all of them?
What about that question tag’s pronoun? Would gender come into consideration?
