I was not sure about the question sentence...it says "If three subzones in all are designated for retail use and a subzone in Z2 is designated for housing, then which one of the following is allowed?"
But zone1 cannot have R, why it says "If three subzones in all..." I thought it's just impossible...where did I misread the question sentence?

It means from the total of all three subzones, you will have 3 R. However, we also know that we can't have R in z1. So, it's their sneaky way of saying 3 R in z2 and z3.

Tina Cho

so does this "in all" means "among all subzones"??
