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: Mia, James, Daniel, Victoria, Evelyn, Owen, and Mason. Mia said that Victoria is a knave and Owen is a knight. James stated, "Evelyn is not a knave". Daniel was heard saying, "Victoria is a knight". Victoria commented, "Mia is a knight and Daniel is a knight". Evelyn told you that Owen is not a knight. "Mason is not a knave" - Owen. "Evelyn is a knave if and only if Evelyn is a knight" - Mason. 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.
