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: Daniel, Harper, Aiden, Michael, and Henry. Daniel noted, "If Michael is a knave then Henry is a knave". Harper commented, "Michael is a knave". Aiden said, "Henry is a knave." Michael told you that Harper is a knight if and only if Michael is a knight. In a statement by Henry: "Harper 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>.
Assistant: Let me solve this step by step.
