40: GWD-29-Q29

Most of Portugal’s 250,000 university
students boycotted classes in a one-day strike to protest a law that requires
them to contribute $330 a
            year
toward the cost of higher education, previously paying $7 per year.

A.     
year toward the cost of higher education, previously paying
$7 per year

B.      
year toward the cost of higher education, for which was
previously paid $7 per year

C.     
year, compared to the previously $7 per year, toward the
cost of higher education

D.     
year toward the cost of higher education, instead of the $7
per year required previously

E.      
year as opposed to the $7 per year required previously for
the cost of higher education

contribute towards/to一个意思。

没有oppose
to这种用法，oppose sth.而且原句中没有oppose的意思。

D比较简洁，意思表达也清楚。

如果加了逗号，如C，句子不完整。
            

问题：instead
of 后面接的东东是不是长了点，不是只能接名词吗？A的paying问题在哪里，虽然感觉不对，但是说不明白？如果是paid对吗？

谢谢~~
