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: Jackson, Chloe, Abigail, Amelia, and Penelope. "Amelia is a knight if and only if Chloe is a knave," Jackson mentioned. Chloe remarked, "Amelia is not a knight". Abigail commented, "Amelia is a knave if and only if Penelope is a knave". As Amelia put it, "If Abigail is a knight then Penelope is a knight". Penelope stated, "If Abigail is a knight then Jackson 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 Jackson is a knight.  No contradiction is found in their claim that Amelia is a knight if and only if Chloe is a knave.
 Assume Amelia is a knight.  No contradiction is found in their claim that If Abigail is a knight then Penelope is a knight.
 Assume Abigail is a knight.  No contradiction is found in their claim that Amelia is a knave if and only if Penelope is a knave.
 Assume Penelope is a knight.  No contradiction is found in their claim that If Abigail is a knight then Jackson is a knight.
 Chloe cannot be a knight, because this would contradict the claim of Jackson that Amelia is a knight if and only if Chloe is a knave.
