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: Emily, Sophia, Victoria, Aria, Ella, Isabella, and Chloe. Emily asserted: "Ella is not a knave". Sophia said, "Aria is a knight or Isabella is a knave." Victoria noted, "If Emily is a knight then Ella is a knight". Aria was heard saying, "If Sophia is a knight then Victoria is a knave". Ella remarked, "Sophia is a knave if and only if Sophia is a knight". Isabella said that Victoria is a knave or Chloe is a knight. According to Chloe, "Victoria is a knight and Isabella 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.
