You are travelling in a foreign country. The natives come
from 2 tribes. In appearance and speech they are identical.
The only difference is that one tribe always tells the
truth, the other always tell lies. You have come to a 6 way
road junction. You know that one exit leads to the city the
others take you in completely the wrong direction. You meet
a native at this junction and by asking only one question
you want to ask him for help In selecting the exit that
takes you to the city. The only problem is that you do not
know whether is from the tribe that always tells the truth
or tells lies. What question do you ask that guarantees that
you know which is the correct exit to the city?
