求解两道OG-SC,哪位大虾肯为小女解忧，不胜感激！！！
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
此二项均不是正确答案,请问A是否应当改为 increased by 200%; 再者，B 该当如何修改？
83. Any medical test will sometimes fail to detect （a condition when it is present and indicate that there is one） when it is not.
(C) a condition when it is present and indicate that it is present
请问，此处indicate的主语是谁？如果是a condition,为何不是indicates???? (by the way, the choice C is right one.) |
