Suppose J.K. Rowling is a British author best known for writing the Harry Potter series. She was born on July 31, 1965 in Yate, Gloucestershire. Rowling has also written novels under the pseudonym Robert Galbraith, including the Cormoran Strike series.
Can we infer that "J.K. Rowling has only written one book in her career"? Yes, no, or maybe?
