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: Aria, Jacob, Sofia, Michael, and Victoria. Aria asserted: "Sofia is a knave or Michael is a knave". As Jacob put it, "Victoria is a knight and Michael is a knave". Sofia remarked, "Aria is a knave and Michael is a knave". Michael commented, "Victoria is a knave and Michael is a knight". Victoria told you that Aria is a knave if and only if Michael 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 Aria is a knight.  No contradiction is found in their claim that Sofia is a knave or Michael is a knave.
 Sofia cannot be a knight, because this would contradict the claim of their own that Aria is a knave and Michael is a knave.
 Assume Sofia is a knave.  No contradiction is found in their false claim that Aria is a knave and Michael is a knave.
 Assume Michael is a knight.  No contradiction is found in their claim that Victoria is a knave and Michael is a knight.
 Victoria cannot be a knight, because this would contradict the claim of Michael that Victoria is a knave and Michael is a knight.
 Victoria cannot be a knave, because this would contradict the false claim of their own that Aria is a knave if and only if Michael is a knave.
 We have exhausted all possibilities for Victoria, so let us go back and reconsider Michael.
 Assume Michael is a knave.  No contradiction is found in their false claim that Victoria is a knave and Michael is a knight.
 Victoria cannot be a knight, because this would contradict the claim of their own that Aria is a knave if and only if Michael is a knave.
 Assume Victoria is a knave.  No contradiction is found in their false claim that Aria is a knave if and only if Michael is a knave.
 Jacob cannot be a knight, because this would contradict the claim of their own that Victoria is a knight and Michael is a knave.
 Assume Jacob is a knave.  No contradiction is found in their false claim that Victoria is a knight and Michael is a knave.
 Therefore, (1) Aria is a knight
 (2) Jacob is a knave
 (3) Sofia is a knave

 (5) Victoria is a knave
