Suppose Harry Potter and the Philosopher's Stone is the first book in the Harry Potter series written by J.K. Rowling. It follows the story of a young boy named Harry Potter who discovers he is a wizard and attends Hogwarts School of Witchcraft and Wizardry.
Can we infer that "Hermione Granger is a character in Harry Potter and the Philosopher's Stone."? Yes, no, or maybe?
