What structural decision does william carlos williams make in "landscape with the fall of icarus" that makes the poem seem short and quick?
a. use of 10 syllables per line
b. the poem's subject matter
c. an alternating rhyme scheme
d. the lack of punctuation

The correct answer is D. The lack of punctuation. It makes the poem sound as if it were a single, swift, concise, and laconic sentence. It also give the poem a conversational tone, depriving it of artificiality that was a characteristic of the pre-20th-century poetry. Punctuation would fragmentise the poem and induce its flow with pauses.
