The correct answer is false.
It is false that the southern landscape of the United States inspired Whitman's poetry.
Walt Whitman (1819-1892) was a poet from the United States, that was renown for his poetic works in the book "Leaves of Grass," of 1855, a collection of twelve poems. He liked to write about friendship, democracy, and love. His works influenced other poets such as C.K. Williams and Ezra Pound. He is considered to be one of the greatest poets in the United States in the 19th century along with Emily D*ckinson.
