>How does that solve it? If you asked that, and the person said "Yes", he could be lying or telling the truth. You have no clue.

If the road leads to the honest village and this is the honest person, he would answer "Yes"

If the road leads to the honest village and this is a liar, he knows, that this road leads to the honest village. If I ask him: "Does this road leads to the honest village?" - he would answer "No". However, I ask: "What do you answer on this question?". He would answer "No", but since he allways lies, he now should answer "Yes" - it's a double negative.

Similarly we would have "No" from both of them, if the road doesn't lead to the honest village.

However, the simpler solution would be just ask: "Do you live in this village?" and show it either direction. I let you follow the logic in this case by yourself.
