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.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
