Suppose The Lord of the Rings is a fantasy novel by J.R.R. Tolkien. It follows the quest to destroy the One Ring, which was created by the Dark Lord Sauron to control Middle-earth. The story is set in the fictional world of Middle-earth and includes characters such as Frodo Baggins, Aragorn, and Gandalf.
Can we infer that "The Lord of the Rings is a non-fiction book."? Yes, no, or maybe?
