Answer: To Emphasize the central idea that Poe's difficult life influenced his writing.
Explanation: I say this because of the details. They included the details of his "hard life" for a reason. What is included into this story only has one explanation when it comes to the answer choices.
Ex. Why would they include that he had gambling problems and so on and so forth is the point of this was to persuade reader to feel sorry for him. Some readers could feel as if he deserved to go into debt because of his problem.
When you analyze each choice with the story the logical answer is what I have put.
