Which is the correct, natural one(s)?

1. [Saying to a doctor] I sometimes can't hear anything. [What case do I in? or What case do I have?]
2. His short height made it hard to see the parade.
3. Zebra's stripes make it hard for its enemies to see it.
4. He arranged (for) the timetable in a manner that left the afternoons free.
5. When you called me, I [sat, was sitting] for (the/a) math exam.
6. The boy felt his tummy/stomach growling for food.
7. You were speeding. Let me show your licence. / No way. I got nowhere near 60 miles an hour. / Yes, but the speed limit here is 40 miles.

Thanks.

Sorry for the title and the question sentence!

Please check if they are all OK and natural!
