# COMMUNITY CHALLENGE
#
# How would you test this Quiz#problem method? Only two rules:
#
# 1. The tests should fail if any part of the application breaks.
# For example: If "gets" is moved before "puts" then the tests should
# fail since that breaks the application.
#
# 2. You cannot change the Quiz class. But you can use whatever framework
# and tools you want for the tests. (RSpec, Cucumber, etc.)
