That's correct That was too easy. Here's a harder logic based one.
A man is walking to a town he doesn't know well. There is a pair of twins guarding the pathways towards the town. One pathway is correct, the other leads to a pit where vicious piranhas lurk ready to tear apart human intestines. He knows that one twin always tells the truth, and one twin always lies. He can only ask ONE twin ONE question. There is no way to tell which twin he is asking. After choosing a twin, what question should he ask?

I've heard this so many times, and have been told THE answer. But I never understood it, and I can't quite remember THE answer.
Isn't it somewhere along the lines of, if I asked the other twin which way is the right one, what would he say?
That's correct. Imagine THE rigth answer is "left". If you ask THE trufhful one what THE liar would say, he will answer "right", since he knows he will be lying. If you ask THE liar what THE truthful one would say, he will lie and say "right" also. So afterwards you know you will have to pick THE other road.
