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