+{"quiz": "A very special island is inhabited only by knights and knaves. Knights always tell the truth, and knaves always lie. You meet 7 inhabitants: Avery, Mason, Evelyn, Charlotte, Emma, Joseph, and Lucas. Avery expressed that Emma is a knight and Mason is a knave.

Charlotte said, \"Mason is not a knave.\" \"Lucas is a knight or Charlotte is a knight,\" Emma mentioned. As Joseph put it, \"Emma is a knight\".
