Answer:
Words such as "delicious", "robust", and "strong" suggest that Whitman's speaker:
C. admires the workers' strength and hard work.
Step-by-step explanation:
Walt Whitman was an American poet who lived from 1819 to 1892. One of his most famous poems is "I Hear America Singing", which we are analyzing here. The poem is patriotic - the speaker is proud of his country, especially of the people who make the country what it is.
Several professions are mentioned throughout the poem, all of them humble yet necessary jobs. Whitman praises the working class and the strength of its men and women. His word choice helps him convey his admiration for them. Words such as "delicious", "robust", and "strong" are intentionally used to express amazement.
"The delicious singing of the mother, or of the young wife at work, or of the girl sewing or washing
[...] - at night the party of young fellows, robust, friendly,
Singing with open mouths their strong melodious songs."
