The number of undergraduate degrees in enginnering 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
答案是(C)我可以接受
但是(B)又錯在哪呢? OG裡面的解釋是 B distorts the sentence's meaning, stating that the number of enginnering degrees conferred increased on more than two distinct occasions. 他這裡指的應該是說增加了兩次 但是為何不能用增加兩倍來解釋呢? 怎麼看對覺得B沒錯
謝謝各位!!
