​

Answer 1

Answer:

Tag questions (or question tags) turn a statement into a question. They are often used for checking information that we think we know is true. Usually if the main clause is positive, the question tag is negative, and if the main clause is negative, it's positive. For example: It's cold (positive), isn't it (negative)?
