User: A very special island is inhabited only by knights and knaves. Knights always tell the truth, and knaves always lie. You meet 4 inhabitants: Victoria, Joseph, Mia, and Evelyn. Victoria was heard saying, "Victoria is a knight or Evelyn is a knight". "Evelyn is a knave or Mia is a knight," Joseph declared. In a statement by Mia: "Victoria is a knave". Evelyn stated, "Victoria is a knave and 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
