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: Logan, Elizabeth, Emma, Grace, and Lucas. Logan noted, "Elizabeth is a knight or Elizabeth is a knave". As Elizabeth put it, "Grace is a knave or Emma is a knight". Emma said that If Lucas is a knave then Elizabeth is a knight. Grace noted, "Emma is not a knave". Lucas told you that If Elizabeth is a knight then Emma 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.
