Answer 2

Hi there!

A question tag is  like a small question or tag added at the end of any declarative sentence. For example: You are going tomorrow. it is a declarative sentence. To make it an interrogative sentence, we have to add aren't you.
When the verb of the declarative sentence is positive, the question tag will we negative. And if the verb of the declarative sentence is negative, then the question tag will be positive.
For example: You did the homework, didn't you?
                      You didn't do the homework, did you?

Hope it helps you!
