Hw1 alice liddell is walking on the island of knights and knaves. she decides that she has had enough walking and would like to go home for tea. she come to a "t" in the road with a vandalized road sign. lying on the ground she sees part of a sign that says "certain death" and another that says "home and tea". she does not know which direction they used to point. lucy is standing next to the left hand road and ricky is standing near the right hand road. alice knows that each of lucy and ricky is either a knave (who always lies) or a knight (who always tells the truth), but does not know which is which or even if they are both knaves or both knights. she may only ask one question to one of the two people. what should alice ask? explain why that works, that is why that is the 'right' question to ask. how would your answer change if there was only one person there?
