Answer
A
The “five second rule” states that if food is picked up within five seconds of dropping it, it will not gather germs.
B
The US surgeon general’s report in 1964 declared that smoking cigarettes was linked to cancer.
C
The Bates method suggests that closing the eyes and thinking of something pleasant can improve vision.
D
Currently, the rate of increase of carbon dioxide in the atmosphere is more than double what it was in the 1960s.
E
A person should not swim right after eating because she could develop severe muscle cramps and drown.
Explanation
The 1964 Surgeon General’s report linked cigarette smoking to cancer based on scientific evidence, so B is an example of science. The increase in atmospheric carbon dioxide can be measured over time, and the stated comparison with the 1960s is supported by observations, so D is also science. The five-second rule, the Bates method’s vision claims, and the warning about swimming right after eating are not reliable scientific conclusions.
