The United States is the product of two principal forces—the immigration of European peoples with their varied ideas, customs, and national characteristics‚ and the impact of a new country which modified these traits.
请问:
1. with their varied ideas, customs, and national characteristics是European peoples的后置定语吗?
2. 一个句子中,既有 and,也有‚and ,该怎么区分呢?
谢谢!
