GWD-29-Q29 这道题灰常纠结

A) "previously paying $7 per year" should refer to the students, which would make it a noun modifier, which is required to be placed next to the noun it modifies. It isn't. Incorrect.

B) this time the phrase isn't even clear - "for which was previously paid" makes no sense

C) "previously" is an adverb and should refer to a verb, but $7 is a noun - you'd need the adjective "previous" here. And really you'd want to say something like "compared to the previous requirement of $7 per year"

D) I'm not a huge fan of this source. I assume the reason to eliminate this one is non-specification that the $7 per year required previously was specifically required for higher education. But I don't think the real test would make this the only distinction. They might also try to claim something's wrong with "instead of" (rather than "as opposed to" in answer E), but instead of can properly refer to a noun, as it does here... so it's fine.

E) See above.

C错在previously副词修饰名词$7。

看这个关于C的解释应该是最贴切的了，previous应该修饰一个副词而不是一个名词短语
