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: Joseph, Jackson, Liam, Ella, and Victoria. Joseph said that Jackson is a knave if and only if Victoria is a knave. In a statement by Jackson: "Victoria is a knight or Victoria is a knave". Liam said, "Jackson is a knight if and only if Victoria is a knave." In Ella's words: "Joseph is a knave if and only if Victoria is a knight". According to Victoria, "Ella is a knight or 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.
