请问一道OG11th语法题第30题

30 An inventory equal to 90 days sales is as much as even the strongest businesses carry, and then only as a way to anticipate higher prices or ensure against shortages.

(A) as much as even

(B)so much as even

(C)even so much as

(D)even as much that

(E)even so much that

这道题答案是A。请问为什么用much而不用many呢？even这里翻译成什么呢？还是只是起加强语气的作用呢？

谢谢
