(A) having hundreds of miniature eyes called ommatidia, help explain why scientists have assumed that it
(B) having hundreds of miniature eyes that are called ommatidia, helps explain why scientists have assumed that they
(C) with its hundreds of miniature eyes that are called ommatidia, helps explain scientists' assuming that they
(D) with its hundreds of miniature eyes called ommatidia, help explain scientists' assuming that it
(E) with its hundreds of miniature eyes called ommatidia, helps explain why scientists have

题目解析：主语是structure，后面的谓语必须用单数，主语和谓语之间的插入成分是迷惑成分，希望你找错谓语，我们把A和D干掉。 B中最后结尾用they，但是根据语意我们知道they指代的应该是eye（单数），不能用they指代，干掉。D和E在explain后面一个加了why一个没有加，explain这个词汇就已经决定了必须加why，否则语意不合理，选E。
