Suppose J.K. Rowling is a British author best known for writing the Harry Potter fantasy series, which has become the best-selling book series in history. Rowling's books have been adapted into a successful film series, merchandise, and a theme park. She is also known for her philanthropic work and advocacy for children's education and welfare.
Can we infer that "J.K. Rowling has never written any other books besides Harry Potter"? Yes, no, or maybe?
