88. 

You are interviewing three forest inhabitants A, B, C. It is known that exactly one of them is a werewolf. In conversation with you, they state:

A: C is the werewolf.

B: I am not the werewolf.

C: At least two of us are liars.

Our task consists of two parts.

a) Is the werewolf a knight or a liar?

b) If you had to choose one of the three forest inhabitants as a travel companion and the question of whether your chosen one would turn out to be a werewolf was more concerning to you than whether they would turn out to be a liar, whom among the three would you choose?
88. C is either a knight or a liar. Suppose C is a knight. Then at least two of the three islanders are liars. Therefore, they must be A and B. From this, we conclude that B is a werewolf (since B claims not to be a werewolf, but B is a liar according to the proof). Thus, if C is a knight, the werewolf is a liar (since it must be B). Now suppose C is a liar. Then it is not true that at least two of the three islanders are liars, so there is at most one liar among them. This liar must be C. Therefore, both A and B are knights. Since A is a knight and claims that C is a werewolf, C is indeed a werewolf. Thus, in this case, the werewolf is also a liar (specifically, C).

Therefore, regardless of whether C is a knight or a liar, the werewolf is a liar (although in each case, it refers to a different individual). So, the answer to the first question is: the werewolf is a liar. Moreover, we have proven that the werewolf can be either B or C. Therefore, if you want to choose a companion who is definitely not a werewolf, you should choose A.
