[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?
If D was a liar, why couldn't [color:"#3A495A"]he answer if A and B were the same[/color]? If he tells the truth, [color:"#3A495A"]does not answering mean A and B are the same, or that he is confused trying to answer a conditional question as 'yes' or 'no'[/color]?
Also technically, [color:"#3A495A"]didn't you say you could
ask two questions, not that you could get two yes/no answers[/color]?
BeeGee;
All of the monks would willingly sacrifice themselves if they knew for sure that they had a red dot. This means that on the first day, all of the monks must have seen at least one dot. Had there been only one dot the monk would not have seen any (and would have jumped knowing he had the dot), so there must be at least two monks with red dots....
