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 7 inhabitants: Ella, Riley, Chloe, Oliver, Ava, Joseph, and Victoria. As Ella put it, "Ava is a knight". "Victoria is a knight or Chloe is a knight" - Riley. Chloe said, "Ella is a knight or Joseph is a knave." Oliver noted, "Joseph is a knight or Riley is a knight". "Victoria is a knight or Riley is a knight," Ava claimed. Joseph stated, "Victoria is a knight and Ella is a knave". Victoria was heard saying, "Chloe is a knight if and only if Joseph 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.
