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: Elizabeth, James, Ethan, Ava, Lucas, Penelope, and Amelia. According to Elizabeth, "James is a knave and James is a knight". James stated, "Ethan is a knight or Penelope is a knight". Ethan said that Ava is not a knave. Ava said, "Penelope is not a knight." Lucas noted, "James is a knave if and only if Penelope is a knave". Penelope said that Lucas is a knave and Elizabeth is a knight. Amelia remarked, "James is a knight and Ava 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.
