Let us say, when a person dies. He comes to a path (purgitory) or so. He walks down this path and gets to a fork in the road like a "Y". One gnome guards each path, one gnome tells falsehoods, the other tells the truth. One of the paths leads to heaven and one of the paths leads to hell.
*You do not know which path is which, or which gnome is which* &You only have 1 question to ask both gnomes, and if you ask one know a question, you have to ask the other gnome the exact same question in turn that will use up your one question! What is the answer(let us say there are no flaws).

Answer 1:
While pointing to one of the paths, Ask one gnome "If I asked you if this is the road to hell, would you say yes?" In this case, you don't need the second gnome. It's a double question and the liar must lie twice to answer it, and the two lies cancel each other out. Answer 2: Point back to the road from which you came and ask one of the gnomes "Is this the road to hell?". Then you will know if the gnome is a liar and so you will know if the other gnome is a liar. Then point to one of the paths and ask the other gnome the same question. eom

Heaven or Hell?
sorry if i did not specify but you can only ask the gnomes one question and the question has to be asked to both of the gnomes.. so i have to discard your Answer 2, which was probably my fault from lack of explination. i came up with ask "what would the other gnome say is the path he guarding" and like your answer one. the gnomes would lie twice and that would cancel out. If one answered "hell" you would know the path he is on would be "heaven" viceversa.

oh yeah your right.. i apologize.. yeah so the gnome would have to tell the truth about lying and the other would have to lie about telling the truth.. .therefore not llie twice.. but yeah.. but would my answer be valid? or just disreguarded.. when i was in high school.. we got half the school trying to figure that out.. it took me 2 days and my friend 3 days to figure it out.. i just want to verify if there are any other possible answers. which in your case yes, for your answer 1

How about...
If honest gnomes go to heaven and lying ones go to hell, which way do you deserve to go? And you only need one gnome!

I don't see anyone asking them to point.

It's irrelevant if the answer is "I would take the right way", or a pointing finger in that direction.

I like the logic of Proggle's solution, and after all, it is a logic puzzle. But it does have a minor flaw. The danger is that the answer will be "I deserve to take the road to heaven.". This would not be helpful. It is easily fixed though, the logic can be preserved with a question like:
If honest gnomes go to heaven and lying ones go to hell, do you deserve to go to the left or to the right? or You could point to one of the roads and ask: If honest gnomes go to heaven and lying ones go to hell, do you deserve to go this way? or If honest gnomes go to heaven and lying ones go to hell, do you deserve to take the road that you guard? eom

"If someone asked you whether your path leads to heaven, would you answer yes?" And the answer would be true.

Pointing works for me.
