Answer:
Tag questions take the form of short questions that are meant to confirm a statement that came before the question.
For example: You're answering Balogun's question on Brainly, aren't you?
Notice how the underlined is a question but it is only meant to confirm the statement preceding it.
1. None can do it, can they?
2. Neither of them went, did they?
3. Nobody went there, did they?
4. Everybody saw you, didn't they?
5. There is no pond in this village, is there?
