Read the excerpt from "A Quilt of a Country."
Once these disparate parts were held together by a
common enemy, by the fault lines of world wars and the
electrified fence of communism. With the end of the cold
war there was the creeping concern that without a focus
for hatred and distrust, a sense of national identity would
evaporate, that the left side of the hyphen-African-
American, Mexican-American, Irish-American-would
overwhelm the right.
What does the use of the term fault lines reveal about
how the author views world wars?
O She believes that world wars are necessary.
She believes that world wars divide Americans.
She believes that world wars are a small concern.
O She believes that world wars are harmful to people.
