大全23，补充题152关于并列的问题

152. A recent New York Times editorial criticized the city’s election board for, first of all, failing to replace outmoded voting machines prone to breakdowns, and secondarily, for their failure to investigate allegations of corruption involving board members.

(A) secondarily, for their failure to

(B) secondly, for their failure to

(C) secondly, that they failed and did not

(D) second, that they failed to（E）

(E) second, for failing to

这句题干中first of all是接在for后面的，这难道不是在提示说second后面的内容也要能直接接到for的后面吗？为什么正确答案中还要重复for呢？

或者还是说first of all和second应该被看成插入语，无关痛痒？请高手指点

根据平行来看，也只有E是正确的，正确答案并不是完美的答案，只是这5个选项中最好的那个。
