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: Ella, Avery, Owen, Scarlett, Charlotte, and Ava. As Ella put it, "Avery is a knave". Avery noted, "If Ava is a knave then Scarlett is a knave". Owen remarked, "Scarlett is not a knight". Scarlett told you that Ava is a knight and Scarlett is a knight. "Avery is a knight if and only if Scarlett is a knight" - Charlotte. Ava said, "Owen is a knight or Charlotte 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.
