Suppose J.K. Rowling is a British author best known for writing the Harry Potter series, which has become the best-selling book series in history. Rowling has garnered numerous awards for her work and has since expanded the Harry Potter universe through various spin-off books and films. She is also known for her philanthropic efforts and advocacy for literacy and children's rights.
Can we infer that "J.K. Rowling has only written one book."? Yes, no, or maybe?
