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 6 inhabitants: Olivia, Michael, Penelope, Scarlett, Joseph, and James. Olivia told you that Scarlett is a knight if and only if Joseph is a knight. "Olivia is a knave if and only if Scarlett is a knight," Michael declared. In a statement by Penelope: "Scarlett is a knave or James is a knave". Scarlett asserted: "Olivia is not a knave". As Joseph put it, "Scarlett is a knight". "Michael is a knave and Joseph is a knave," James claimed. 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.
