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 3 inhabitants: Riley, Amelia, and Ethan. "Amelia is not a knight," Riley declared. Amelia asserted: "Riley is a knight or Amelia is a knight". According to Ethan, "Riley is a knight and Ethan 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.

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