perplexus.info :: Liars and Knights : Knights,liars,and knaves

Knights,liars,and knaves (Posted on 2003-05-26)

Knights always tell the truth,liars always lie,and knaves alternate between truths and lies.

Suppose you ask a native,"Are you a knight,a liar,or a knave?" The native answers,and you are able to figure out what he is.

What is the native?
