                The Gunning fog index was developed by Robert Gunning in 1952 after working in newspaper and textbook publishing. It is
                primarily used to ensure that text can be easily read by a large audience. The index was refined in the 80s to more accurately
                measure and incorporate sentence complexity.

              <p>
                In general, texts intended for a wide audience are recommended to have a fog index of no more than 12. Texts requiring
                near-universal understanding and comprehension are recommended to keep their fog index below 8.
