Suppose Harry Potter and the Philosopher's Stone is a fantasy novel written by British author J.K. Rowling. It is the first novel in the Harry Potter series and follows Harry Potter, a young wizard who discovers his magical heritage on his eleventh birthday when he receives a letter of acceptance to Hogwarts School of Witchcraft and Wizardry.
Can we infer that "The main character in Harry Potter and the Philosopher's Stone is a non-magical human."? Yes, no, or maybe?
