The quote is from Lewis Carroll's "Alice's Adventures in Wonderland" where the King asks Alice what she knows about a particular business. Alice responds that she knows nothing at all, indicating her lack of knowledge or experience in that matter. The King’s insistence highlights a curiosity or suspicion about Alice’s understanding or involvement.
Overall, this exchange showcases Alice's honesty and innocence, as well as the whimsical and sometimes absurd interactions in Wonderland. It emphasizes themes of ignorance, curiosity, and the playful nature of the characters she encounters in her fantastical journey.
