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: Scarlett, Charlotte, Emily, Lily, and Olivia. Scarlett was heard saying, "Lily is not a knave". Charlotte told you that Lily is a knight. Emily told you that Scarlett is a knave. "Scarlett is a knight if and only if Olivia is a knight," Lily declared. In a statement by Olivia: "Charlotte is not 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.
