Question

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 is the connotative meaning of fault lines in this excerpt? something powerful and threatening something familiar and interesting something harmless and pleasant something amusing and impressive

Explanation:

In the context of world wars, "fault lines" is used metaphorically. World wars are large - scale, powerful, and threatening events. The term "fault lines" in geology refers to areas of weakness that can lead to earthquakes (powerful and threatening natural events). Here, it is extended to the context of world wars, which are also powerful and have the potential to cause great destruction (threatening).

Answer:

something powerful and threatening
