Final answer:
Allen Ginsberg's poems "Howl" and "Hum Bom!" make extensive use of the Whitmanian literary device of anaphora, which is the repetition of a word or phrase at the beginning of successive lines.
Step-by-step explanation:
Allen Ginsberg's "Howl" and "Hum Bom!" extensively use a Whitmanian literary device at the start of nearly every line, known as anaphora, which is the repetition of a word or phrase at the beginning of successive clauses. This technique is not listed in the provided options, but it is important to note that anaphora is a key characteristic of both poems, reflecting the influence of Walt Whitman's stylistic achievements in American poetry. Although alliteration, assonance, metaphor, and hyperbole are also literary devices that can be found in Ginsberg's work, they do not specifically characterize the starting of nearly every line as described in the question.
