Answer to Question 1

Chlorofluorocarbons, or CFCs, resulted in the chemical decomposition of ozone. Ozone is an atmospheric gas
that is critical in blocking biologically harmful UV-B light in the upper atmosphere.



Answer to Question 2

According to the EPA, 50 parts per million is the highest safe level of CO gas. Homes and businesses should be
protected by CO detectors.

The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
