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.
O She believes that world wars are a small concern.
O She believes that world wars are harmful to people.
