Read the excerpt from "safari day in kenya.”
hyenas slink before us, mottled bodies, eyes black ice
zebras bright as painted ponies, the babes brown-striped, not black!
which statement best describes how the author uses sound devices to create mood?
the author uses onomatopoeia to create a disjointed mood.
the author uses onomatopoeia to create a joyful mood.
the author uses alliteration to create a playful mood.
the author uses alliteration to create an angry moo

We can observe the use of alliteration and onomatopoeia in the options. Alliteration is the repetition of the sounds and onomatopoeia is a word or phrase that imitates the sound. We cannot observe the latter in the excerpt. But we can certainly observe alliteration in the repetition of the sounds b and p:

before us, mottled bodies, eyes black ice

bright as painted ponies, the babes brown-striped, not black

Additionally, the author uses a playful mood, not the angry one because of the description of the animals. We don't observe the angry nature of hyenas or zebras. Therefore, the correct answer is the third one - The author uses alliteration to create a playful mood.
