Question

i need this answer immediatly, because i have posted this question one week ago. i was waiting for the answer.please send me the asnwer as soon as possible.

4. A Canadian variant of an old puzzle: A traveler in remote Quebec comes to a fork in the road and does not know which way to go to get to Chicoutimi. Henri and Pierre are two local inhabitants nearby who do know the way. One of them always tells the truth, and the other one never does, but the traveler does not know which is which. Is there a single question the traveler can ask Henri (in French, of course) that will be sure to tell him which way to go? We will formalize this problem in FOL. Assume there are only two sorts of objects in our domain: inhabitants, denoted by the constants henri and pierre; and French questions, which Henri and Pierre can answer. These questions are denoted by the following terms: a gauche, which asks if the traveler should take the left branch of the fork to get to Chicoutimi; dit.ouix,q), which asks if inhabitant x would answer yes to the French question q;
