Rosen Ex1.1 Q No. 45

Question

Each inhabitant of a remote village always tells the truth or always lies. A villager will only give a "Yes" or a "No" response to a question a tourist asks. Suppose you are a tourist visiting this area and come to a fork in the road. One branch leads to the ruins you want to visit, the other branch leads deep into the jungle. A villager is standing at the fork in the road. What one question can you ask the villager to determine which branch to take?

Answer 1

assuming left is the answer.

A) It is true that you are the truth teller and the left road leads to ruins or you are a liar and the right road leads to ruins?

B) If I ask you whether the left road leads to ruins, you will say yes, won't you?

C) If I ask the other kind of person whether the right road leads to the ruins, he will say yes, won't he?

ok we are tourist here so we don't know the road and let's assume right one is the correct road and we asked same A question so before reaching or part the liar will make the statement $\sim$(F $\wedge$ F ) True
hence he is a liar he complemented and made that true so what can we interpret from this? is 1 the correct road or he is the one telling the truth?

oh no my reasoning is wrong you are right
complement is done on the whole expression
