There are two types of creatures:
- truthers, who always tell the truth, and
- liars, who always lie.
It is not possible to distinguish them by appearance, but only by the truth or falsity
of the statements they make.
1) A stranger met two inhabitants, A and B, and asked A, "Is any of you a truther?". "If B is a liar, then I am a liar, too.", replied A.
What are A and B?
2) The stranger went on. In the evening, he began to look for a shelter for the night, but was very cautious because he knew that some of the inhabitants were maneaters and it was not possible to recognize them by appearance. Then he met three inhabitants, C, D and E. He asked C, "How many of you are truthers?".
"Flam flim", answered C in her language. "What did she say?", asked the stranger D. "Just one", replied D. "Do not trust D, he is a liar. Come with
me, I'm not a man-eater", said E. "No, come with me, I'm not a man-eater",
countered D.
What should the stranger do?

1) I think that A and B are both truthers.
2) I'm absolutely lost. HELP.
