When I want ask somebody what kind of person he (or she) isn't, which one between these is correct? Or are they interchangeable? I guess they are interchangeable.
A: "What kind of person are you not?"
B: "What kind of person aren't you?"
If you think we can't use either of them, please explain why we can't while we can say "What kind of person are you?". Also, if you think only one of them is correct please explain why we can use it while we can't use the other one.
