% 0.20/0.70  % English  : There is an island with exactly two types of people -
% 0.20/0.70  %            truthtellers who always tell the truth and liars who always lie.
% 0.20/0.70  %            There are a group of three people, A, B, and C on the island.
% 0.20/0.70  %            A and B make the following statements. A: "B and C are the same
% 0.20/0.70  %            type". Someone asks "Are A and B of the same type ? " What does
% 0.20/0.70  %            C answer? Answer: "yes"
