as well as 与and的区别请教

197. In the fall of 1985, only 10 percent of the women entering college planned to major in education, while 28 percent chose business, making it the most popular major for women as well as for men.

(A) as well as for men

(B) as well as the men

(C) and men too

(D) and men as well（A）

(E) and also men

Two elements connected by a coordinate conjunction should be expressed in parallel form. Only A, the best choice, correctly observes this rule (the most popular major for women as well as for men). B, C, D, and E omit the necessary for in the second element. In addition, by using the simple coordinate conjunction and, C, D, and E create the illogical impression that the decision of 28 percent of the women entering college in 1985 to choose business as a major also made the major the most popular among men. The conjunction as well as implies that business had already been the most popular major for men and that in 1985, for the first time, it became the most popular major for both sexes.

兰色部分不理解，我觉得最近有个a critique的真提也有as well as的用法，和and 怎么区别，谢谢大家，集思广益。
