Again A answered indistinctly, so Abercrombie askedB what A had said. B then said that Ahad said that exactly two of themwere knaves.

B和C有一个是无赖1.B和C说的话恰好相反,因此它们的身份必定相反。2.A说的数字不可能是2。因为:2.1如果A是骑士,那只能有一个无赖,2就不是事实2.2如果A是无赖,那恰好有两个无赖,2就是事实。3.所以B在说谎。4.结论:C是骑士。这个问题已经得到解了。但是,假如我们还想知道究竟A说的是什么,有可能确定吗?你还记得前面推出“任何岛民不会说“我是无赖”吗?

问题2:推理中是否有些规律与具体的内容无关?比如说:我们知道两件事中必有一件事发生,也只会有一件事发生那么,如果知道其中一件肯定发生,我们就可以推断另件事肯定不会发生,我们甚至不需要知道那究竟是什么事
比如说: 我们知道两件事中必有一件事发生,也只会有一件事发生, 那么,如果知道其中一件肯定发生,我们就可以推断另一 件事肯定不会发生,我们甚至不需要知道那究竟是什么事
问题3:我们怎么才能将这些规律表达出来,并让他们发挥作用?识别对象,理清关系,语言表达
