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: Sophia, Owen, Daniel, Aiden, and Ethan. Sophia was heard saying, "Daniel is a knight or Ethan is a knave". According to Owen, "Aiden is a knave or Aiden is a knight". Daniel remarked, "Sophia is not a knight". Aiden expressed that If Daniel is a knight then Aiden is a knight. As Ethan put it, "Owen is a knight and Sophia 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 Sophia is a knight.  No contradiction is found in their claim that Daniel is a knight or Ethan is a knave.
 Daniel cannot be a knight, because this would contradict the claim of their own that Sophia is not a knight.
