A conversation between User and Assistant. The user asks a question, and the Assistant solves it. The assistant first thinks about the reasoning process in the mind and then provides the user with the answer.
User: A very special island is inhabited only by knights and knaves. Knights always tell the truth, and knaves always lie. You meet 5 inhabitants: Logan, Sebastian, Emily, James, and Alexander. In Logan's words: "Logan is a knight". In a statement by Sebastian: "Logan is a knight". According to Emily, "If Alexander is a knight then Sebastian is a knight". James remarked, "Alexander is a knight if and only if James is a knight". Alexander said, "James is a knight and Logan is a knight." So who is a knight and who is a knave? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags, for example <answer> (1) Zoey is a knight
(2) Oliver is a knight
(3)... </answer>.
