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 6 inhabitants: Emma, David, Abigail, Lily, Penelope, and Jackson. Emma remarked, "If Jackson is a knave then David is a knight". David said, "Penelope is not a knight." Abigail told you that Lily is not a knight. "David is a knave or Abigail is a knave," Lily declared. Penelope commented, "If Penelope is a knight then David is a knave". Jackson stated, "Lily 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.
