Isn't I is the tail question

Answer 2

Answer: I have two brothers, don't I ?

Explanation:

A tag question usually involves an anchor with positive polarity followed by an interrogative with negative polarity. The verb 'have' means - I do + have,

hence, as the first part is positive, the tag in the second part would be negative.

Bring the hidden auxiliary from 'have' to the tag, apply negative polarity. Done.
