[color:"#3A495A"]Ask D "IF A AND B ARE DIFFERENT, is A a truth-teller?"[/color]
<img src="/ubbthreads/images/graemlins/think.gif" alt="" /> Technically, isn't that two questions?
Nope. Given a situation, you ask whether something is true or not. "Suppose
this is true, would
that be true?". The first part is not a question, it's a hypothetical fact.
One or two questions: "If my socks have different colors, is my left sock orange?"
Suppose you're a liar, and suppose my socks are the same color. Suppose they're green.
Since you ALWAYS lie, you will never answer the truth. Now, the first part of my question, turns the whole question into a hypothetical situation: the fact that my socks are both green becomes irrelevant, and there is no way to KNOW whether my left sock would be orange, if my socks were a different color. So, the answer to the question COULD be either yes or no. And so, you can't answer either because either COULD be true, and you NEVER tell the truth. If you answered, you COULD be telling the truth, so for once in your life you realise you have to shut up! (To put it gently <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />)
Then again, you probably got that part, on to the other technical issue:
Also technically, [color:"#3A495A"]didn't you say you could ask two questions, not that you could get two yes/no answers[/color]?
A yes or no question is simply a question that can only be answered by yes or no. Hey, that's common knowledge. <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />
There would be no point in saying you can only ask yes or no questions if they can answer anything they want. They could answer "non of your g*dd*mn business" and then what? Then, compadre, we have a
really stupid riddle <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
(You don't really want me to post the complex answer to be happy, do you? <img src="/ubbthreads/images/graemlins/think.gif" alt="" /> )
