请教小兰里面的一道题

托福要考一百一

1. 
   

The use of chemical pesticides in this country is equally extensive or more so than ten years ago.
A.equally extensive or more so than ten years ago
B.equal to or more extensive than ten years ago
C.as extensive as ten years ago or more
D.equal to, if not more, than ten years ago
E.as extensive as it was ten years ago, if not more so

答案是e   但是我觉得E改变了原意，而且more...than不是应该成对出现的吗？我选的是B

If you choose B, it should be:

"equal to or more extensive than that of ten years ago"

aeoluseros

if not more so是省略用法，算是一个more...than不同时出现的特例.
A和B比较对象都是不对等的，就如ls所说.
