"the montana sunset lay between two mountains like a gigantic bruise from which dark arteries spread themselves over a poisoned sky." the simile used in this sentence gives the reader an impression of
a) hollow wonder.
b) pain and danger.
c) gracious indifference.
d) questions and answers.

The correct answer is B.

Explanation:

The sunset is compared to a bruise which is usually the consequence of a painful encounter. Therefore, it immediately brings to mind a picture or memory of a painful encounter to the reader that was memorialised by a bruise as visible and vivid as a sunset. Furthermore, the comparison goes on to include "dark arteries" which is another painful experience as dark arteries are usually hardened arteries. They also block the adequate flow of blood which is a dangerous condition. And finally, the imagery closes with the mention of "a poisoned sky" which is another insinuation at danger as poison is a dangerous substance that often leads to a fatality.
