"What would you say if I asked?" Guard B therefore lies twice: "I would say yes" = He would really say No = The path is safe. And vice versa.
I still don't think you are getting it...
1. You can only ask one question (the same question) of both guards.
2. You don't know which guard is the liar or which tells the truth, (and the one that lies always lies -- he would not tell the truth, e.g. use reverse psychology.
Only by asking
"Which path would the other guardian say you would say is safe?"
can you know to take the opposite path to the one they both say the other would say is safe.
But I am growing tired of this.
"Is it safe?"
talk reminds me of Laurence Olivier's character as he's working on Dustin Hoffman's teeth in the movie Marathon Man.
