The belief that while each of us will pursue our own individual dreams 奥巴马演讲的一句话

Question

The belief that while each of us will pursue our own individual dreams, we are an American family and we rise or fall together as one nation and as one people.
是什么从句？

Answer 1

这应该是一个名词短语吧：
The belief 是中心词；that引导了一个同位语从句，这个同位语从句本身又是一个复合句。
在这个复合句，while each of us will pursue our own individual dreams是一个让步状语从句，we are an American family and we rise or fall together as one nation and as one people是一个主句。

Answer 2

我们的信仰：每一个个体追求自己各自的梦想时，我们同时也是一个美国大家庭并且我们作为一个国家一个民族共繁荣共衰落。

Answer 3
