朋友寫信問我一個輕鬆有趣的題目，跟大家分享一下
Mr. Short, his sister, his son, and his daughter are fond of golf and often
play together. The following statements are true of their foursome:
(1) The best player's twin and the worst player are of the opposite sex.
(2) The best player and the worst player are the same age.
Which one of the foursome is the best player?
