1998 saw several new ventures promoting online distance learning both at the college and graduate level, but also faculty members in large numbers began questioning whether the computer screen was an adequate replacement for the classroom.
(A) 1998 saw several new ventures promoting online distance learning both at the college and graduate level, but also faculty members in large numbers began
(B) In 1998 several new ventures were promoting online distance learning for both college-and for graduate-level courses, but it was also a year for a large number of faculty members who began
(C) With several new ventures promoting online distance learning both for college and graduate courses in 1998, it was also a year when a large number of faculty members had begun
(D) Although 1998 saw several new ventures promoting online distance learning for both college- and graduate-level courses, it was also a year when a large number of faculty members began
(E) Several new ventures were promoting online distance learning in 1998, at both the college level as well as the graduate, but it was also a year for faculty members to begin in large numbers
(C) both…and结构不平行. 使用with结构改变了原句的逻辑关系,把两个并列成分变为了主从成分;had begun使用过去完成时没有依据.
已经看见好几个题出现这段话了把两个并列成分变为了主从成分
能请各位解释一下吗？？？怎么从原文看出是并列
谢谢aeoluseros回答！！！

噢 ＬＳ的意思是就是原来是...but...并列结构 现在Ｃ选项改成了with... it...
我还是有一点不明白 这里的with... 应该是独立主格结构吧？？独立主格也和主句构成主从关系吗？？为什么不是对等的关系呢？？谢谢谢谢！！！
