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: Isabella, Riley, Samuel, and Liam. Isabella stated, "Riley is a knight or Isabella is a knight". Riley was heard saying, "Isabella is a knight or Liam is a knight". "If Samuel is a knight then Riley is a knight," Samuel declared. Liam noted, "Samuel is a knight or Isabella is a knave". So who is a knight and who is a knave? Show your work in <think> </think> tags.

(2) Oliver is a knight
(3)... </answer>.
