Answer to Question 1

Fiber contains -glycosidic bonds that are resistant to digestive enzymes, so fiber passes intact (undigested) through the small intestine to the large intestine. Intestinal bacteria break down the fiber, producing gas, lipids, and other substances that nourish the cells that line the colon. Fiber prevents the overgrowth of unhealthy (pathogenic) bacteria by promoting the growth of healthy bacteria.

Answer to Question 2

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.
