Suppose Stephen King is an American author of horror, supernatural fiction, suspense, crime, science-fiction and fantasy novels. His books have sold more than 350 million copies, and many have been adapted into films, television series, miniseries, and comic books. King has published 61 novels, including seven under the pen name Richard Bachman, and six non-fiction books.
Can we infer that "Stephen King only writes science-fiction novels"? Yes, no, or maybe?
