You are at one end of a hall blindfolded. At the other end are Alex and Bert. You are allowed to ask any yes or no questions you want, but only one of them will respond. They are standing next to each other and their voices are identical, so you have no way of telling which one responded by sound alone.
Using as few questions as possible, find out the type of each Alex and Bert and who answered your last question.

It actually never says whether either is a liar or a knight at all. Still we should try to find a solution that alows for 2 liars or 2 knights...
