72. The number of undergraduate degrees in engineering awarded by colleges and universities in the United States increased by more than twice from 1978 to 1985.
A.increased by more than twice
B.increased more than two times
C.more than doubled
D.was more than doubled
E.had more than doubled
解释：Choice A is faulty because an adverb such as twice cannot function as an object of the preposition by
那么A怎么改算对呢？ ... increased by more than 50% 对吗？
Thanks...

介词by后面不能跟副词，可以跟数词。

twice 是副词，所以不能接在BY 后面，如果要改，我认为你的修改正确

这里twice 和 increase是重复语义，同时twice是副词，不可以跟在介词by 后面

你的修改是正确的
