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 6 inhabitants: Jacob, Zoey, Ella, James, Liam, and Benjamin. Jacob told you that If James is a knight then Ella is a knight. In Zoey's words: "If Liam is a knight then Liam is a knave". Ella told you that If Liam is a knave then Ella is a knight. As James put it, "If Zoey is a knave then Zoey is a knight". Liam expressed that Ella is a knight if and only if James is a knight. "Jacob is a knight or Liam is a knave," Benjamin claimed. 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.
