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: James, Owen, Logan, Elizabeth, Jacob, Scarlett, and Zoey. "Elizabeth is a knight" - James. "If Zoey is a knave then Elizabeth is a knight," Owen declared. In a statement by Logan: "If James is a knight then Logan is a knight". Elizabeth was heard saying, "Elizabeth is a knight if and only if Zoey is a knave". Jacob stated, "If Zoey is a knave then Elizabeth is a knave". Scarlett noted, "Jacob is a knave and Owen is a knave". Zoey was heard saying, "Scarlett is a knight if and only if Jacob is 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.
