Explanation
Correct answer: C.
Choice C is the best answer because it most effectively illustrates the claim that the narrator of "The Yellow Wallpaper" has mixed feelings about her surroundings. She says she is "really getting quite fond of the big room," a positive sentiment, but also describes the room’s wallpaper as "horrid," a negative sentiment. Since some of her feelings about her surroundings are positive and others are negative, they are best described as mixed.
Why the other choices are wrong
Choice A
Choice A is incorrect because though the narrator describes the room’s wallpaper as "irritating," a negative sentiment, she does not mention a positive sentiment. Thus, the quotation does not effectively illustrate the claim that the narrator has mixed feelings about her surroundings.
Choice B
Choice B is incorrect because it describes how the appearance of the room’s wallpaper changes at night but does not mention the narrator’s feelings about her surroundings.
Choice D
Choice D is incorrect because though the narrator describes the room’s wallpaper as "repellant," a negative sentiment, she does not mention a positive sentiment. Thus, the quotation does not effectively illustrate the claim that the narrator has mixed feelings about her surroundings.
