(E) only of the five-nation Iroquois League had sided
这题正确答案是C，我想问的是选C的话，主句的谓语动词在哪里呢？难道是sided吗？
不明白，谢谢。

(A) banked with dirt to a height of
(B) banked with dirt as high as that of
(C) banked them with dirt to a height of
(D) was banked with dirt as high as
(E) was banked with dirt as high as that of
这道题目里 overlaid with 和banked with 都不可能作为谓语动词出现的吧？那么上题C中的sided with?
