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: Chloe, Henry, and Mason. "Henry is a knight if and only if Henry is a knave," Chloe declared. Henry noted, "Chloe is not a knight". Mason noted, "Chloe is a knight if and only if Chloe 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.

Chloe cannot be a knight, because this would contradict the claim of their own that Henry is a knight if and only if Henry is a knave.
 Assume Chloe is a knave.  No contradiction is found in their false claim that Henry is a knight if and only if Henry is a knave.
 Assume Henry is a knight.  No contradiction is found in their claim that Chloe is not a knight.
 Mason cannot be a knight, because this would contradict the claim of their own that Chloe is a knight if and only if Chloe is a knave.
 Assume Mason is a knave.  No contradiction is found in their false claim that Chloe is a knight if and only if Chloe is a knave.
 Therefore, (1) Chloe is a knave
 (2) Henry is a knight
 (3) Mason is a knave
