8. You are walking down a road and come to a fork. One path leads to certain death; the other leads to eternal happiness. You don't know which is which. In the middle of the fork, you come across two brothers who know which road is which. One brother always tells the truth and the other always lies. You can only ask them one question. How would you determine which road to take?

Respuesta :

Answer:

Ask "If I asked your brother what the good door is, what would he say?"

Explanation:

If you ask the truth-telling brother, he will point to the bad door, because this is what the lying brother would point to.

Alternatively, if you ask the lying brother, he will also point to the bad door, because this is NOT what the truth-telling brother would point to.
