You are in the countryside near Boise, in the US state of Idaho. The road forks. One road leads to the Democrat';s country club, where you want to go, the other leads to the Republican';s country club. Democrats always tell the truth, while Republicans always lie. There are two perosns at the intersection, one Republican and one Deomocrat, but of course you don';t know who is from which party. You have just one question to find out where to go. What is your question?
呵呵,这是我学的一门逻辑课,一次作业里面的一题.大意是:你走在一条乡间小路,路在前面有了分叉,一条是去向民主党人的地方,这是你想去的地方.另一条路去向共和党人的地方.在分叉处站着两个人,一个是民主党人,一个是共和党人(当然,你不知道哪个是民主党人,哪个是共和党人).民主党人只说真话,共和党人只说假话.你只能问他们两个人同一个问题,根据他们的回答,你得出哪条路是你想去的地方.
请问你该问什么问题?
呵呵,我当时想了半天,一开始怎么都觉得不可能,后来一不小心想出来了,你们想想~ |
