Since 1986 enrollments of African Americans, American Indians, and Hispanic Americans in fulltime engineering programs in the United States has steadily increased, while the number of other students who enter the field has fallen.
D) have steadily increased, while the number of other students entering the field has falled
E)have steadily increased, while that of other students who enter the field fell
我想請問各位大大,在D選項entering是修飾number 還是other students.
而後面的has falled modifies the numbers?
至於在E選項enter應該是修飾students?
