Verbal 2nd sc98 求nn解答

slave918

98. Although Napoleon’s army entered Russia with far more supplies than they had in their previous campaigns, it had provisions for only twenty-four days.
(A) they had in their previous campaigns,
(B) their previous campaigns had had,
(C) they had for any previous campaign,
(D) in their previous campaigns,
(E) for any previous campaign,

OA is E.
我知道前4个选项是因为主谓不一致。
我想问各位NN的是: E选项中这个比较是如何完成的？因为我找不到和E中的for any previous campaign想比较的内容。
Thanks in advance!
