Awriter makes a forceful contrast between expectations and reality, creating a surprise ending for readers. which literary device is the author using?

idk that a good answer

explanation:

as for symbolic actions, the narrator's tearing down the wallpaper in an attempt to find the "woman" in the wallpaper represents her struggle to retain or regain her sanity.   the wallpaper has been part of her confinement and by her tearing it down, she is freeing herself from that confinement.
