Suppose The Harry Potter series, written by J.K. Rowling, consists of seven books: 'Harry Potter and the Philosopher's Stone', 'Harry Potter and the Chamber of Secrets', 'Harry Potter and the Prisoner of Azkaban', 'Harry Potter and the Goblet of Fire', 'Harry Potter and the Order of the Phoenix', 'Harry Potter and the Half-Blood Prince', and 'Harry Potter and the Deathly Hallows'. The series follows the life of a young wizard, Harry Potter, and his friends Hermione Granger and Ron Weasley, as they attend Hogwarts School of Witchcraft and Wizardry.
Can we infer that 'J.K. Rowling wrote a total of 8 Harry Potter books.'? Yes, no, or maybe?
