% 0.19/0.61  % Problem  : Looking for Oona
% 0.19/0.61  % Version  : Especial.
% 0.19/0.61  % English  : In another curious incident, when the husband arrived on an
% 0.19/0.61  %            island looking for Oona, he met 5 natives A,B,C,D,E who all
% 0.19/0.61  %            guessed his purpose and grinned at meeting him. They said:
% 0.19/0.61  %            A: Oona is on this island. B: Oona is not on this island.
% 0.19/0.61  %            C: Oona was here yesterday. D: Oona is not here today, and she
% 0.19/0.61  %            was not here yesterday. E: Either D is a knave or C is a knight.
% 0.19/0.61  %            The logician thought for a while, but could get nowhere. `Won't
% 0.19/0.61  %            one of you please make another statement?' the logician pleaded.
% 0.19/0.61  %            At this point A said: Either E is a knave or C is a knight. Is
% 0.19/0.61  %            Oona on the island?"
