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 4 inhabitants: Jack, Chloe, Samuel, and David. As Jack put it, "David is a knave or David is a knight". Chloe noted, "David is a knight and Samuel is a knave". In Samuel's words: "Chloe is a knight and David is a knave". David stated, "Samuel is not 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 Jack is a knight.  No contradiction is found in their claim that David is a knave or David is a knight.
 Assume David is a knight.  No contradiction is found in their claim that Samuel is not a knight.
 Samuel cannot be a knight, because this would contradict the claim of their own that Chloe is a knight and David is a knave.
 Assume Samuel is a knave.  No contradiction is found in their false claim that Chloe is a knight and David is a knave.
