Suppose Harry Potter and the Sorcerer's Stone is the first novel in the Harry Potter series written by J.K. Rowling. The book was first published in 1997 and follows the story of a young wizard named Harry Potter. The novel was later adapted into a successful film franchise starring Daniel Radcliffe.
Can we infer that "J.K. Rowling wrote the entire Harry Potter series in one day."? Yes, no, or maybe?
