1. Describe three binary conditions which people experience on a daily basis.

On/Off, Male/Female, AM/PM, Married/Unmarried, Dead/Alive, etc.

(Note: Each of these are truly binary states: One is, for example, either married or unmarried; contrary to some beliefs, on cannot be partially married or partially unmarried. Similarly, High/Low is NOT a binary condition, since there are an infinite number of levels between high and low).
