Questions that offer a challenge
 

It is likely difficult to understand what type of sentences I am referring to, so all give a few examples. These questions are intended to challenge the validity of certain claims:

Isn't there an 'H' in your name?
Haven't you left yet?
Doesn't he look like you?

I appreciate all the responses, thanks! !

Make an effort.

Here are some hints:

- ¿No ___ H tu nombre?
- ¿Todavía no ***insert the verb "ir" as a pronominal here***?
- ¿No ***insert the verb "parecer" as a pronominal in third person*** a ti?
