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 7 inhabitants: Ava, Grace, Luke, Owen, Sebastian, Mia, and Chloe. Ava commented, "Luke is a knight and Mia is a knave". In Grace's words: "If Mia is a knight then Sebastian is a knight". Luke stated, "Mia is a knave or Chloe is a knight". Owen said, "Mia is not a knight." In Sebastian's words: "Luke is a knave or Chloe is a knave". In Mia's words: "Owen is a knave". Chloe was heard saying, "If Sebastian is a knave then Ava is a knave". 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.
