敢问路在何方?在数学王国的东南和东北方向座落着两个村庄,其中一个叫诚实村,另一个叫说谎村.诚实村的各个居民都说实话,而说谎村的居民都说谎话.一名商人途径数学王国的一条东西大道去诚实村谈生意(如图1),当商人临近交叉路口时,见交叉路口上相向走来一人,商人知道这人是这两个村庄中的人,但不知道是哪个村庄的,也不知道哪条道通往诚实村.商人灵机一动,只问了此人一句话,便知道哪条路能往诚实村,你能猜出商人是怎样问的吗?
Dare to ask where the road is? There are two villages located in the southeast and northeast direction of the mathematical kingdom, one of which is called Chengshi Village and the other is called Lie Village. The residents of the honest village are telling the truth, and the residents of Lie Village are all lying. A businessman walks through an east-west road in the mathematical kingdom and goes to honest village to talk about business (see Figure 1). When a businessman approaches the intersection, he sees one person on the crossroads. The merchant knows that this person is a person in these two villages. But I don’t know which village it is, and I don’t know which road leads to Chengshi Village. When the businessman is invigorated and only asks this person a word, he knows which way can go to honest village. You can guess how the businessman asks. ?
