Long ago in a galaxy far away there was a planet of liars and truth
tellers, it is known that liars always tell lie, and truth tellers
always respond with correct statements. All the inhabitants of the
planet look identical to each other, so there is no way to distinguish
between liars and truth tellers just by looking at them.
The planet is ruled by the government, where one may encounter honest
governors as well as liars. The government is controlled by the High
Council, where again one can meet liars and truth tellers.
