SC-og10-17 qestion help

17. Native American burial sites dating back 5,000 years indicate that the residents of Maine at that time were part of a widespread culture of Algonquian-speaking people.
(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

Choice A is best because it correctly uses the simple past tense, the residents... at that time were, and because it is the most concise. In B and D, the replacement of were with the past perfect had been needlessly changes the original meaning by suggesting that the Native Americans had previously ceased to be part of the widespread culture. All of the choices but A are wordy, and in C, D, and E the word people redundantly describes the residents rather than the larger group to which the residents belonged. These choices are also imprecise because they state that the culture, rather than people, spoke the Algonquian language. Choice E displays inconsistent tenses and an error of pronoun reference, people which.

question-----------------------------------

the residents of Maine at that time (were part of a widespread culture of Algonquian-speaking people)
residents were part of a ... culture of ... people
residents到底等同于culture还是等同于people？

注解中，
wrong choice C ：were people who were part of a widespread culture that was Algonquian-speaking
the word (people) redundantly describes the (residents) rather than the (larger group to which the residents belonged)
说people错误地指residents而不是指residents所属的那个更宽泛的群体
我觉得不存在这个问题啊，只是were people who不太consice 而已。没有指代错误。所以不太理解OG注解的这种说法。

牛牛来详细指点一下吧，偶可能钻到牛角尖里去了，HELP！

people有两层意思1.名族；2.复数意思单数形式的人们

C：如果是民族，肯定错

如果说是“人们”的话，指代是没错，但是were people who were part of a是非常的罗索的，很多都是多余的，OG的解释是说redundantly describes 多余的描述，OG没说它错，只是多余，不够简洁

C的另外一个错误就是culture that was Algonquian-speaking这里的意思是【说Algonquian的文化】

而题目的意思，明显是【说Algonquian的民族】

所以C是肯定错的，废话多，还改意思

ask again. I still did not understand why choose A?

residents=culture?

or

residents=people?

thanks!
