这里用 each 是因为前面 dwellings 是复数，现在要逐一描写，所以就用 each 来带出
是独立主格结构的应用
我解释这么多就能选出答案，不到你的困惑
capability in doing 是错误用法，应为capability in sth./to do sth./of doing sth
a选项because引导从句，
你不应白啥...

thanks edward!Q3为什么不选d呢？

要是从考点上讲，本题就是考的each的独立主格结构~
cde是一下就排除的
要是从日常的方法来讲，with的结构是很容易 引发歧义 ，尽量慎重选择，本题with加上就是修饰主语的了很不通的，你仔细想想，就不是对前面的名词解释了
我给你写一下完整的句子是lived in open-sided, flat-topped dwellings known as shades, each （of which） is a roof of poles and arrowweed supported by
括号中的是省略的~
你应该明白点了吧~~
