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: Charlotte, Daniel, Aiden, Emily, Jack, Olivia, and Isabella. Charlotte told you that Daniel is a knight and Emily is a knight. Daniel asserted: "Olivia is a knight or Olivia is a knave". Aiden asserted: "Isabella is a knight if and only if Charlotte is a knave". "Olivia is a knight," Emily declared. Jack asserted: "If Daniel is a knight then Emily is a knave". Olivia said that Jack is a knave and Aiden is a knave. According to Isabella, "Aiden is not 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.
