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

正确答案是B，因为与papers 主谓一致应该使用represent 而不是represents
但是题目中作为papers 的同位语是a strong defence 和an important body，这样还能够将papers 理解为复数吗？
