Read the following poem and answer the questions that follow:
Apostrophe to Man Detestable race, continue to expunge yourself, die out. Breed faster, crowd, encroach, sing hymns, build bombing airplanes; Make speeches, unveil statues, issue bonds, parade: Convert again into explosives the bewildered ammonia and the distracted cellulose; Convert again into putrescent matter drawing flies The hopeful bodies of the young: exhort, Pray, pull long faces, be earnest, be all but overcome, be photographed: Confer, perfect your formulae, commercialize Bacteria harmful to human tissue, Put death on the market: Breed, crowd, encroach, expand, expunge yourself, die out, Homo called sapiens.

The last line – “Breed, crowd, encroach, expand, expunge yourself, die out” has the figurative device termed:

The correct option is Alliteration.

Alliteration is a literary and figurative device characterized by the repetition of the same initial sound (consonant or vowel) in a sequence of neighboring words. In the final line of the poem:
"Breed, crowd, encroach, expand, expunge yourself, die out"
We can clearly observe a sequence of three consecutive verbs that begin with the same vowel sound and letter 'e':
- encroach
- expand
- expunge
This repetition of the initial "e" sound in close proximity creates the distinct auditory pattern known as alliteration.

To understand why the other options do not apply, let us examine their definitions:
- Synecdoche: A figure of speech in which a part of something is used to represent the whole (e.g., using "wheels" to refer to a car). There is no such part-to-whole representation in this line.
- Spoonerism: A verbal slip or play on words where corresponding consonants or vowels are swapped between words (e.g., saying "blushing crow" instead of "crushing blow"). No such phonetic swapping occurs here.
- Palindrome: A word, phrase, or sequence that reads the same backward as forward (e.g., "radar"). The given line is not symmetrical in spelling.
Therefore, the correct literary device used is indeed Alliteration.
