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: Victoria, Owen, Sofia, Liam, and Joseph. "Owen is a knave," Victoria mentioned. Owen stated, "Liam is a knave and Joseph is a knave". As Sofia put it, "Joseph is a knave if and only if Liam is a knight". "If Liam is a knight then Victoria is a knight" - Liam. Joseph was heard saying, "Liam is a knave or Victoria 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.

Assume Victoria is a knight.  No contradiction is found in their claim that Owen is a knave.
 Owen cannot be a knight, because this would contradict the claim of Victoria that Owen is a knave.
 Assume Owen is a knave.  No contradiction is found in their false claim that Liam is a knave and Joseph is a knave.
 Assume Liam is a knight.  No contradiction is found in their claim that If Liam is a knight then Victoria is a knight.
 Joseph cannot be a knight, because this would contradict the claim of their own that Liam is a knave or Victoria is a knave.
