On an island there are, as usual, two types of people: humans and vampires. Humans always tell the truth and vampires always lie. But the difference is that half the population is crazy, and therefore reverses the values of truth and lies. This circumstance results in a crazy human being lying, while a crazy vampire tells the truth. Based on these premises, is it possible to find out with one and only question if a person:
Is it a human or a vampire?
Is she crazy or rope?
Is he a sane vampire?
Is he a crazy vampire?
Is he a crazy human?
Is he a sane human?
