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: Elizabeth, Ethan, Logan, Sophia, and Victoria. Elizabeth said, "Victoria is a knight and Ethan is a knight." Ethan told you that Sophia is not a knave. "Ethan is a knight," Logan claimed. Sophia remarked, "If Elizabeth is a knave then Logan is a knave". Victoria asserted: "Victoria is a knight and Elizabeth 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.
