下記の文章の中で パッチワークというよりモザイクだという内容だと思うのですが どのような違いがあるのでしょうか？ パッチワークは布と布とで出来たもの、 モザイクはもう少し壊れやすもの、、 アメリカは　布と布というよりはもう少し壊れやすいものの 集まり・・・ こういった解釈でよいのでしょうか？ Without a common American identity, the United States has become little more than a conglomeration of separate and different social group. As each group becomes more and more self-sufficient, more ties are broken with the rest of society, resulting in self-segregation. As fewer threads remain to hold together our increasingly fragile society, the less we look like a patchwork quilt and the more we begin to look like a mosaic, held together only by our proximity to one another.
