cloud by sandra cisneros

if you are a poet, you will see clearly that there is a cloud floating in this sheet of paper. -thich nhat hanh

before you became a cloud, you were an ocean, roiled and murmuring like a mouth. you were the shadows of a cloud cross- ing over a field of tulips. you were the tears of a man who cried into a plaid handkerchief. you were the sky without a hat. your heart puffed and flowered like sheets drying on a line. and when you were a tree, you listened to the trees and the tree things trees told you. you were the wind in the wheels of a red bicycle. you were the spidery maria tattooed on the hairless arm of a boy in downtown houston. you were the rain rolling off the waxy leaves of a magnolia tree. a lock of straw-colored hair wedged between the mottled pages of a victor hugo novel. a crescent of soap. a spider the color of a fingernail. the black nets beneath the sea of olive trees. a skein of blue wool. a tea saucer wrapped in newspaper. an empty cracker tin. a bowl of blueber- ries in heavy cream. white wine in a green-stemmed glass. and when you opened your wings to wind, across the punched- tin sky above a prison courtyard, those condemned to death and those condemned to life watched how smooth and sweet a white cloud glides.

the effect of the sounds in the phrase “wind in the wheels” is that they

a)create a sense of isolation
b)use language that is very grounded and realistic
c)work against the overall theme in the poem
d)evoke the sound of the wind
