Which character detail in "Object Lesson, Part 2" best creates reader uncertainty?

Marianne moore’s “poetry” is written in defense of poetry. in the excerpts, which three lines or phrases reflect moore’s opinion of what good poetry should be? . . to discriminate against "business documents and school-books"; all these phenomena are important. one must make a distinction however: when dragged into prominence by half poets, the result is not poetry, nor till the poets among us can be "literalists of the imagination" —above insolence and triviality and can present for inspection, "imaginary gardens with real toads in them," shall we have it. in the meantime, if you demand on the one hand, the raw material of poetry in all its rawness and that which is on the other hand genuine, you are interested in poetry.
