# How would you test this Quiz#problem method? Only two rules:
# 1. You must test the order the gets/puts happen. The tests should not
# still pass if "gets" happens before "puts", etc.
# 2. No changing the Quiz class implementation/structure. But you can
# use whatever framework you want for the tests.
