The idiomatic form for this type of comparison is as much as. Thus, choice A is best. The phrase so much as is used unidiomatically in choices B and C; so much as is considered idiomatic if it is preceded by a negative, as in “She left not so much as a trace.” In choices C, D, and E, even is misplaced so that it no longer clearly modifies the strongest businesses. Moreover, the use of that rather than as is unidiomatic in choices D and E. 推荐楼主看一下OG, 里面的解释很清楚. |
