(A) and important as a body of work in political science as well, represents

(B) as well as an important body of work in polit­ical science, represent

(C) and also a body of work of importance in polit­ical science is representing

(D) an important body of work in political science and has been representative of

(E) and as political science an important body of work too, represent

我有疑问的是选项D

关于现在完成式部分

我一开始的理解是这样: the federalist 这部论文,呈现了3个不同作家的作品

这部论文已经完成了吗??是阿,在过去完成的

那么论文的影响有一直延续吗??有阿

所以我觉得用现在完成式並沒有不合理的地方

og的解释如下: D, employing the present perfect tense, suggests that the situation of triple authorship is no longer the case

我不理解为什么说"no longer the case"??

完成是不是有隐含延续的动作含意吗??????

困惑中

现在完成时表明将来不一定这样. OG这样解释我们就这样理解吧.

OG里有一些其他相似的例子.
