Which excerpt from kurt vonnegut's "report on the barnhouse effect" is an example of irony?

a. professor barnhouse closed his eyes, pursed his lips, and stroked his temples. he held the position for a minute.

b. at ten minutes before h-hour the general came in, shepherding the professor before him. the professor was comfortably attired in sneakers, gray flannels, a blue sweater, and a white shirt open at the neck.

c. the tenth still told me nothing. it was only last night that i discovered how it fitted in with the rest. the sentence appeared in my thoughts last night, while i was toying absently with the professor's dice.

d. dutifully and fearfully i watched. a high-pitched humming seemed to come from the inkwell; then it began to vibrate alarmingly.

The harlem renaissance dawned in an era of pervasive racism and segregation. although legally "free," many african americans were still bound by ideas that had their roots in the slavery of earlier centuries. identity and freedom are important ideas presented in many of the poems from the harlem renaissance. furthermore, the values of identity and freedom are not unique to particular times and places. as hughes expresses in "dream variations," all humans want to be able to develop their identities in freedom. what role does freedom play in the poems you read in this unit? what is required of a society to enable each individual to be true to his or her identity and be free to live by that identity? write about at least three of the poems, describing how the poet uses imagery to depict freedom and identity, the lack of it, or the desire for it.
