Answer:
The effect of parallelism in this excerpt is:
B. It emphasizes the sizeable burden imposed by the summons.
Step-by-step explanation:
"The Fall of the House of Usher" is a short story by author Edgar Allan Poe. The narrator of the story has been invited to his friend's house. However, once he approaches the residence, he is overcome with depression. This is clearly a burden to him, and the parallelism he uses to describe the house and the atmosphere is a reflection of that. All those details, given out one after the other, are supposed to show readers how sad and yet annoying it is for the narrator to have to come and spend time at such a gloomy place. The house itself seems depressed, lifeless.
