The accretionary wedge is like the accretionary prism and the definition of that is : *a mass of sedimentary material scraped off a region of oceanic crust during subduction and piled up at the edge of the overriding plate (source : dictionary)* and the formation is when two plates crash and one slides under the other one I believe and sand ad sediment go into the little open space between them that give you a wedge.

Answer:
D. They establish a false expectation for the reader of an unremarkable session.
Explanation:
The paragraphs mentioned in the question above, present in the short story "After dark" present the painter and narrator of the story, receiving the recommendation to make a picture of Mr. Boxsious and the reaction of the painter to observe the whole landscape that was in front of him, when I was at Mr. Boxsious's house, awaiting his arrival. These moments in the narrative present common situations, such as nothing surprising, intriguing and peculiar. This makes the reader think that the painting session will follow that same tone and that there will be nothing curious, but this is a false hope, since Mr. Boxsious, transforms the painting session into something totally new.
