Answer:
"Can dogs identify colors?" is scientific while "Are dogs better pets than cats?" is not.
Explanation:
"Can dogs identify colors?" is scientific because it is a hypothesis that can be tested, it avoids opinion, it is specific, and the experiments involved in proving it can be repeatable. These are all characteristics of a good scientific question. "Are dogs better pets than cats?" is not scientific because it is opinionated, and it does not involve any experiments that would fail or prove it.
