有一位农夫,经营着一家农场,每年年终岁末,农夫都会对有贡献的驴进行奖赏,表现最好的驴每天可以吃到15个玉米棒子。但随着农场规模的逐步扩大,数十头驴在农场劳作,一下子还真难说清楚谁表现好、谁表现差,究竟该奖励谁呢?农夫越来越犯难了。 A farmer runs a farm. Every year at the end of the year, the farmer rewards donated donkeys. The best performing donkey can eat 15 corn cobs a day. But as the size of the farm gradually expanded, dozens of donkeys worked on the farm. It was hard to say who performed well and who did poorly at any one time.
