difficult problem

Three intersections are set as intersection 1, intersection 2 and intersection 3.

Pick two at random and ask God: 1 Is intersection 3 a dead end?

When the two intersections you choose are dead ends, when God answers "Yes": 1. If it is true, the rest is the only way. 2. If it is a lie: Because there must be a dead end, the lie is not absolute and cannot be answered. When God answers "No": 1. If it is true: Answer "No", that is to say, intersection 1 and intersection 3 are all paths, so there is only one path, so you can't answer it. 2. If it's a lie: Answer "No", that is, it's all one way. Because it's a lie, the fact is that everyone is dead, and the rest is a road.

When there is a road at the intersection you choose, God can't answer it. If the intersection 1 is a road, God answers "Yes". If it is true, the 1 intersection becomes a dead end. If it's fake, intersection 3 becomes a road again. God replied, "No". If it is true, intersection 1 and intersection 3 are both living paths. If it is false, intersection 1 and intersection 3 are dead ends, which do not conform to the characteristics of forever true or forever false.

So when there is a way out at the intersection you choose, God can't answer. That is to say, as long as God answers, no matter whether he answers "yes" or "no", the only way left is the road.
