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

这道题大家争来争去都是争CDE里哪个对，我选了B，我不知道哪里错了……

for which was previously paid $7 per year 正常语序就是 $7 per year was previously paid for which 并没有缺少主语呢

还有 towards和toward 有什么区别吗？

这里contribute toward是词组吗？请问大家要查一个词或者短语在GMAT里的用法，应该去哪里查呢？

自己来顶下

除了A和C可以排除掉以外

BDE我一个也排除不掉……
