Read the excerpt from "a quilt of a country."
the new york of my children is no more balkanized, probably less so, than the philadelphia of my father, in which jewish boys would walk several blocks out of their way to avoid the irish divide of chester avenue. (i was the product of a mixed marriage, across barely bridgeable lines: an italian girl, an irish boy. how quaint it seems now, how incendiary then.) the brooklyn of francie nolan's famous tree, the newark of which portnoy complained, even the uninflected wasp suburbs of cheever's characters: they are ghettos, pure and simple. do the cambodians and the mexicans in california coexist less easily today than did the irish and italians of massachusetts a century ago? you know the answer.
what technique does quindlen use to support the idea that america is less polarized now than it was in past history?

Anne Quindlen, the writer of "A Quilt of a Country" uses vivid imagery to show the idea that America is less polarized now than it was in the past.

Explanation:

Pulitzer Prize award winner Anne Quindlen wrote "A Quilt of a Country" in the aftermath of the 9/11 attack to demonstrate and emphasize the unity of the American people in the face of adversity. Even though America is inhabited by various nationalities with unique and distinct traditions, they all come united when fighting against issues such as terrorism. In the above passage, she is reiterating the America of today, the America that is no longer biased against outsiders. Instead, it has become a place where everyone can stay peacefully, while they can still uphold their own cultures. Through all the various problems, it has retained it's unity and that is what makes America a great nation.

the author develops a cold, and scared tone. making the reader shudder with fear, and suddenly become cold. i'm guessing that he's writing a scary novel, or maybe about a chilly december night.
