Определимся, где надо вставлять Are, где - Is, где - Am:
I :: Am
You :: Are
He :: Is
She :: Is
It :: Is
We :: Are
They :: Are
Таким образом, получаем:
1) Are we from Belarus?
2) Is it a brown lion?
3) Are you fine?
4) Are they from Africa?
5) Are Bob and Tom friends?
6) Is she nice?
7) Am I a good pupil?
8) Are his sons funny?
9) Is Liz happy?
