1) When we came to the stadium, the match__
a) was starting
b) had started

I think both a and b will do but my teacher said that only b can. How come?

2) How can I put into words this idea:
"She is studying one class ___ mine".( This sentence means, for instance, I'm at grade 11 and she's at grade 12). Can I use "above" to fill in the blank?

1. I agree both are possible.

2. Above seems right
