The theater group began today with a warming up game.
Everyone has been assigned a role and is now either a bad guy who always lies, or a good guy who always tells the truth.
Max, who comes late, is asked to explore the roles of Jan and Jörg through yes-no questions.
"Are you both good guys ?", he asks Jan, who is full in his role, but his answer is not enough to know who has which role.
Max asks Jörg: "Is Jan a good guy ?" After Jörgs answer Max is fully informed and can name the roles of the two.
What counts ?
(A) Both are evil.
(B) Both are good.
(C) Jan is a good guy, Jörg a bad guy.
(D) Jörg is a good guy, Jan a bad guy.
