Suppose J.K. Rowling, known for writing the Harry Potter series, was born on July 31, 1965, in Yate, Gloucestershire, England. She began writing the series when she was a single mother living on welfare. The series has since become a global phenomenon, with millions of copies sold worldwide and multiple film adaptations.
Can we infer that "J.K. Rowling has only written the Harry Potter series."? Yes, no, or maybe?
