Question

In a certain mythical community, politicians never tell the truth, and nonpoliticians always tell the truth. a stranger meets three citizens of the community and asks the first of them, "are you a politician?" the first citizen answers the question. the second citizen then reports that the first citizen denied being a politician. the third citizen says that the first citizen is a politician.

Answer 1

I'm not really sure what the question is. If you are asking which of the citizens are politicians, then I believe the answer is both citizens 2 and 3. Only citizen 1 answered the question, while the other two changed the topic by accusing citizen 1.
