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: Zoey, Ella, Ethan, Sophia, and Chloe. As Zoey put it, "If Ethan is a knight then Chloe is a knight". "Sophia is not a knave," Ella claimed. Ethan said, "Zoey is a knave." Sophia asserted: "If Ethan is a knave then Chloe is a knight". Chloe remarked, "Zoey is a knight or Ella 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 Zoey is a knight.  No contradiction is found in their claim that If Ethan is a knight then Chloe is a knight.
 Ethan cannot be a knight, because this would contradict the claim of their own that Zoey is a knave.
 Assume Ethan is a knave.  No contradiction is found in their false claim that Zoey is a knave.
 Assume Chloe is a knight.  No contradiction is found in their claim that Zoey is a knight or Ella is a knight.
 Assume Ella is a knight.  No contradiction is found in their claim that Sophia is not a knave.
 Assume Sophia is a knight.  No contradiction is found in their claim that If Ethan is a knave then Chloe is a knight.

 (2) Ella is a knight
 (3) Ethan is a knave
 (4) Sophia is a knight
 (5) Chloe is a knight
