Explanation:

These two authors have some specific and distinctive way of writing that set them apart from most of their peers at the time, one of these characteristics was how much detail they put into the description not only of the characters but to the environment surrounding them, this gave a very dramatic feeling to their work, two of the best examples of this are "An Occurrence at Owl Creek Bridge" and "The Red Badge of Courage"
