13.M: What sort of grade did you get on your research paper? I know how hard you worked on it.
W: Yeah, well, I was hoping for something really good. But the professor said that I made too many broad claims that weren't support enough.
Q: What can be inferred about the woman's paper?
The answer is (B) It wasn't as good as she thought.
請問broad claims是什麼意思呢? 廣泛的主張? 是說沒有立論根據的主張嘛? or....?
Thanks
