Suppose Harry Potter and the Philosopher's Stone is the first novel in the Harry Potter series and J.K. Rowling's debut novel. It 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. The novel won several awards and has been translated into multiple languages.
Can we infer that "Hermione Granger is the main protagonist of Harry Potter and the Philosopher's Stone"? Yes, no, or maybe?
