Which of the following lines from the selection includes descriptive details that contribute to the mood? A. “In feeling my way I had found many angles” B. “The angles were simply those of a few slight depressions” C. “The entire surface of this metallic enclosure was [covered] in . . . hideous and repulsive devices” D. “In its size I had been greatly mistaken.”

Respuesta :

C. “The entire surface of this metallic enclosure was [covered] in . . . hideous and repulsive devices”

"hideous" and "repulsive" show a negative and disturbed mood
You answer will be C ("The entire surface of this metallic enclosure was [covered] in...hideous and repulsive devices"). 

This sentence gives you a sense of what the author wants you to actually feel, and for you to feel this the author is using strong adjectives (like hideous). The adjectives within the sentence are mood-setting in a negative manner.
