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: Ella, Elizabeth, David, Penelope, Charlotte, James, and Liam. Ella told you that David is a knight. As Elizabeth put it, "David is a knave". David expressed that David is a knight and James is a knight. "Liam is not a knight," Penelope claimed. Charlotte stated, "David is a knight and James is a knight". James told you that David is not a knave. In a statement by Liam: "Penelope is a knight and James 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.
