This is the first section of the quiz. It consists of four logic puzzles.

There are two people, A and B, each of whom is either a knight or a knave. A knight always tells the truth and a knave always lies. A makes the following statement:  A: "At least one of us is a knave." What are A and B? Correct Answer: A is a Knight  and B is a Knave. Explanation: Suppose A were a knave. Then the statement "At least one of us is a knave" would be false (since knaves make false statements); hence they would both be knights. Thus, if A were a knave he would also have to be a knight, which is impossible. Therefore A is not a knave; he is a knight. Therefore his statement must be true, so at least one of them really is a knave. Since A is a knight, then B must be the knave. So A is a knight and B is a knave.

We have three people, A, B, C, each of whom is either a knight or a knave. As before, A knight always tells the truth and a knave always lies. A and B make the following statements: A: “All of us are knaves” B: “Exactly one of us is a knight.” What are A, B, C? Solution: A is a Knave, B is a Knight and C is a Knave   Explanation: To begin with, A must be a knave, for if he were a knight, then it would be true that all three are knaves and hence that A too is a knave. If A were a knight he would have to be a knave, which is impossible. So A is a knave. Hence his statement was false, so in fact there is at least one knight among them. Now, suppose B were a knave. Then A and B would both be knaves, so C would be a knight (since there is at least one knight among them). This would mean that there was exactly one knight among them, hence B's statement would be true. We would thus have the impossibility of a knave making a true statement. Therefore B must be a knight. We now know that A is a knave and that B is a knight. Since B is a knight, his statement is true, so there is exactly one knight among them. This knight must be B, hence C must be a knave. Thus the answer is that A is a knave, B is a knight, and C is a knave.

Question 4: We have three people, A, B, C, each of whom is either a knight or a knave. Two people are said to be of the same type if they are both knights or both knaves. A: "B is a knave." B: "A and C are of the same type." What is C?
• A.

C = Knight

• B.

C = Knave
