求教：og10--17

(A)  were part of a widespread culture of Algonquian-speaking people

(B)   had been part of a widespread culture of people who were Algonquian-speaking

(C)  were people who were part of a widespread culture that was Algonquian-speaking

(D)  had been people who were part of a widespread culture that was Algonquian-speaking

(E)   were a people which had been part of a wide­spread, Algonquian-speaking culture

本题正确答案为A，但是在这里的句子结构为：  … the residents … were … culture. residents 意思是居民，而 culture的意思是文化，难道我们能说“居民是文化”吗，或者我的理解有错误？

新手第一次发文，还望高手指教。

先读
        were part of a
widespread culture 文化的一部份
            

然後
Algonquian-speaking people修饰文化

说Algonquian语言的人的文化的一部份

那么翻译过来还是说的是“Maine的居民”是“MingLiU","serif";">说AlgonquianMingLiU","serif";">语言的人的文化的一部份”。也就是说，居民可以成为文化的一部分是吧，这样倒是还能说得过去。MingLiU","serif"; mso-fareast-font-family: 宋体; mso-fareast-theme-font: minor-fareast;">

呵呵，非常感谢您的回答呢。
