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 4 inhabitants: Samuel, Aria, Chloe, and Emily. According to Samuel, "Chloe is a knave and Aria is a knave". As Aria put it, "Chloe is a knight and Samuel is a knight". "Samuel is a knight or Emily is a knight," Chloe declared. Emily expressed that Chloe is a knight if and only if Aria 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.

Assume Samuel is a knight.  No contradiction is found in their claim that Chloe is a knave and Aria is a knave.
 Chloe cannot be a knight, because this would contradict the claim of Samuel that Chloe is a knave and Aria is a knave.
 Chloe cannot be a knave, because this would contradict the false claim of their own that Samuel is a knight or Emily is a knight.
 We have exhausted all possibilities for Chloe, so let us go back and reconsider Samuel.
 Assume Samuel is a knave.  No contradiction is found in their false claim that Chloe is a knave and Aria is a knave.
