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: Riley, Isabella, Victoria, Logan, and Mason. Riley stated, "If Mason is a knave then Mason is a knight". In Isabella's words: "Victoria is a knave or Victoria is a knight". In a statement by Victoria: "If Riley is a knight then Mason is a knave". Logan stated, "Mason is a knave and Isabella is a knight". Mason expressed that Victoria is a knight or Victoria 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.
