Answer: 4. Walt Whitman is known for his use of imagery.
Step-by-step explanation:
Walt Whitman (1819-1892) was an American poet.
In his poems, Whitman often used imagery - vivid language and sensory details that engage the reader's senses and emphasize the author's point.
For instance, in "Song of Myself", his famous poem, visual imagery is used multiple times in order to describe nature:
"Where the panther walks to and fro on a limb overhead" ;
"Where the rattlesnake suns his flabby length on a rock" ;
"Where the alligator in his tough pimples sleeps by the bayou" , etc.
