Final answer:
The development of a central idea from the excerpts transitions from America's unity in diversity to the challenges in living up to this ideal, highlighting the contrast between the unifying concept of equality and the realities of intolerance and bigotry that exist.
Step-by-step explanation:
The development of a central idea from one paragraph to the next in the excerpt from "A Quilt of a Country" can be best understood by looking at how the first and second paragraphs contrast with each other. The first paragraph introduces the idea that America is a nation built on diverse and ever-changing parts, united by the concept of equality. The second paragraph delves into the reality that America's history and present are fraught with acts of intolerance and bigotry that tarnish this unifying ideal. Hence, the passage transitions from presenting the ideal of unity in diversity to exposing the struggles and failures in living up to that ideal.
The notion of American Exceptionalism plays a significant role in this context. It suggests that notwithstanding the unique opportunity that America represents, the history of inequality and repression towards various groups cannot be overlooked. The contrast between the ideal portrayed in founding principles and the historical reality serves as a reflection of the struggles to achieve a multicultural and equitable society.
This struggle is further enriched by the acknowledgment of a multicultural America where different groups, such as African Americans, Native Americans, Asian Americans, and others, contribute to the nation's fabric yet face challenges. Authors have grappled with portraying America's diversity in literature, reflecting not a monolithic culture but a tapestry of different experiences and perspectives.
