you are in a land inhabinated by people who either always tell the truth or always tell falsehoods. You come to a fork in the road and you need to know which fork leads to the capital. There is a local resident there, but he has time only to reply to one yes-or-no question. What one question should you ask so as to learn which fork to take?
suggestion: Make a table.
The Attempt at a Solution
If I asked you 'does the right way lead to the capital?', would you anwser 'yes'?
If the guy reply yes, take the right way. If no, the left.
I am wondering if I am surposed to ask questions about 'future' here?
What exactly does the writer mean by 'make a table'?
