Answer and Explanation:
America's expansion contributed to the strength and diverse nature of his literary works. This is because this expansion allowed people to be subjected to completely different factors in different regions of the country, in addition to encompassing cultures and attracting many immigrants who already had literary elements that were adapted to American culture. Because it is such a large country, the regions promoted life experiences and visions of the world that were totally different among people, which profoundly influenced the authors. We can see this diversification through Southern Gothic works, which addressed the theme, visions and scenarios that were not addressed in the literature of the rest of the country.
