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: Ella, Zoey, Scarlett, Henry, and Amelia. Ella expressed that Zoey is a knight or Zoey is a knave. In a statement by Zoey: "Scarlett is a knave". Scarlett commented, "Ella is a knave or Amelia is a knave". "Scarlett is a knight or Amelia is a knight," Henry declared. According to Amelia, "Henry 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.
