Suppose J.R.R. Tolkien wrote the fantasy novel 'The Lord of the Rings', which consists of three volumes: 'The Fellowship of the Ring', 'The Two Towers', and 'The Return of the King'. The story follows the quest to destroy the One Ring, which was created by the dark lord Sauron to control Middle-earth.
Can we infer that 'J.R.R. Tolkien wrote 'Harry Potter and the Philosopher's Stone'?
