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: Daniel, Sophia, Scarlett, Lily, and Owen. In a statement by Daniel: "Lily is not a knight". As Sophia put it, "Daniel is a knight if and only if Lily is a knave". Scarlett stated, "Daniel is a knave". Lily asserted: "Owen is a knave and Lily is a knight". Owen asserted: "Scarlett is not 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 Daniel is a knight.  No contradiction is found in their claim that Lily is not a knight.
 Lily cannot be a knight, because this would contradict the claim of Daniel that Lily is not a knight.
 Assume Lily is a knave.  No contradiction is found in their false claim that Owen is a knave and Lily is a knight.
 Assume Owen is a knight.  No contradiction is found in their claim that Scarlett is not a knave.
 Scarlett cannot be a knight, because this would contradict the claim of their own that Daniel is a knave.
 Scarlett cannot be a knave, because this would contradict the claim of Owen that Scarlett is not a knave.
 We have exhausted all possibilities for Scarlett, so let us go back and reconsider Owen.
 Assume Owen is a knave.  No contradiction is found in their false claim that Scarlett is not a knave.
 Scarlett cannot be a knight, because this would contradict the claim of their own that Daniel is a knave.
 Assume Scarlett is a knave.  No contradiction is found in their false claim that Daniel is a knave.
 Assume Sophia is a knight.  No contradiction is found in their claim that Daniel is a knight if and only if Lily is a knave.
 Therefore, (1) Daniel is a knight
 (2) Sophia is a knight
 (3) Scarlett is a knave
 (4) Lily is a knave
 (5) Owen is a knave
