Questions: Part B Which quotation from "A Quilt of a Country" best supports the answer to Part A? These [people who died in the World Trade Center destruction] are the representatives of a mongrel nation that somehow, at times like this, has one spirit. Like many improbable ideas, when it actually works, it's a wonder. America is an improbable idea, a mongrel nation built of ever-changing disparate parts, it is held together by a notion, the notion that all men are created equal, though everyone knows that most men consider themselves better than someone. "Of all the nations in the world, the United States was built in nobody's image," the historian Daniel Boorstin wrote.

The answer is the first one: "These [people who died in the World Trade Center destruction] are the representatives of a mongrel nation that somehow, at times like this, has one spirit. Like many improbable ideas, when it actually works, it's a wonder."

Explanation for each option:

1. "These [people who died in the World Trade Center destruction] are the representatives of a mongrel nation that somehow, at times like this, has one spirit. Like many improbable ideas, when it actually works, it's a wonder." - This quotation supports the idea that despite America's diverse and disparate nature, it can come together as one unified entity, especially in times of crisis. It highlights the theme of unity amidst diversity, which is central to the text.

2. "America is an improbable idea, a mongrel nation built of ever-changing disparate parts, it is held together by a notion, the notion that all men are created equal, though everyone knows that most men consider themselves better than someone." - While this quote discusses the diversity and the foundational idea of equality in America, it does not directly address the unity that emerges in times of crisis, which is the focus of the answer to Part A.

3. "Of all the nations in the world, the United States was built in nobody's image," the historian Daniel Boorstin wrote. - This quote emphasizes the uniqueness of the United States but does not specifically address the theme of unity in diversity or the coming together of the nation in challenging times.

4. "What is the point of a nation in which one part seems to be always on the verge of fisticuffs with another ...?" - This quote highlights the internal conflicts and divisions within the nation, which contrasts with the theme of unity and does not support the idea of coming together as one spirit.
