Answer: D. It makes the scene come alive by describing Elk Creek in detail
Step-by-step explanation:
Imagery refers to the figurative language that's contained in a literary work whereby the narrator uses images to describe something.
One of the effect of the poet's use of imagery in this excerpt is that it makes the scene come alive by describing Elk Creek in detail.
The options that the use of imagery suggests that the Kiowas have been victimized by U.S. troops or shows how many spiders came out in the evening are incorrect.
The correct option is D.
