Explanation:
This is called tag question. Tag questions start with a statement first then end with question.
This question tag will rely on verb + subject
For verb, can only be verb to be, modal verb, verb to do, verb to have.
Examples:
If a sentence starts with negative or affirmative, the verb will be opposite.
If a sentence starts with present simple or past tense, only use verb to do for tag.
