Ayear toward the cost of higher education, previously paying $7 per year
Byear toward the cost of higher education, for which was previously paid $7 per year
Cyear, compared to the previously $7 per year, toward the cost of higher education
Dyear toward the cost of higher education, instead of the $7 per year required previously
Eyear as opposed to the $7 per year required previously for the cost of higher education
答案是D
C为什么是错的？我看有解释是说previously是副词，所以不能直接修饰$7.但是我不可以理解为compared to the $7 per year previously吗？副词的位置应该是可以随便放的呀？
