og213，请问paper的用法

213.The Federalist papers, a strong defense of the United States Constitution and important as a body of work
in political science as well represents the handiwork of three different authors.
(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(B)
(E) and as political science an important body of work too, represent

og里说‘Choices A, C, and D contain singular verbs that do not agree in number with the plural subject, papers.’

想问的是paper在这里是什么意思？“各种报纸？”我记得paper是不可数名词啊，什么时候用复数谓语呢？

还有og里面好像有一题，说一本书的名称里面是复数的，但是谓语用单数的。能不能把The Federalist papers看作一本书呢？就像什么《读者》精选？

谢谢

斑竹，那在这里怎么翻译呢？

还有能回答一下第2个问题吗？不可以看出一本书的书名吗？

谢谢

回答一下第二个问题，参考一下：

The Federalist papers不能当作一本书，因为你看OG的原文﹙不是电子版﹚，The Federalist是粗斜体，就像The Bible一样，所以只有The Federalist被当作书名。

呵呵,插个话,

象这种书名之类的,正式考试中会用粗斜体标出来吗

同位语和定语从句有什么区别呀? 

这道题目的同位语部分怎么看好象都可以按定语从句来理解.
