premise: A man wearing a blue lab coat, safety glasses, and gloves is working at a small machine with a large computer screen.
hypothesis: The man is doing science.
explanation_1: A man can wear a lab coat and work at a small machine with a large computer screen without doing science.
explanation_2: The man could be doing a variety of things, but he is specifically doing science.
explanation_3: We cannot infer that the man is doing science just because he is working on a machine.
