premise: A black scientist looks through a scope examining a biological specimen's blood cells.
hypothesis: he looks through the microscope before lunch
explanation_1: Not all scientists are men. Just because they were looking through a microscope does not mean they were doing it before lunch.
explanation_2: It does not specify if the scientist is examining the blood cells before lunch.
explanation_3: With a mention of a clock or time of day being mentioned we don't know it is before lunch.
