I just want to verify if my reasoning is correct:
I was between B and C first; E seemed like an answer but at the same time, it was a direct reiteration of line 46 to 48 so I was iffy about it.
Also, I was actually looking for the word "qualify" because the initial part of the 3rd paragraph qualified her work by saying how she made a revision to her theory.
But the reason to dismiss B is, I think: B says some other works qualify her theory; this isn't true. Her study itself qualified it. Hmm... at the same time I am not sure the word "research" refers to her work or someone else's work. Either way though, qualifying her work isn't the "primary" but "secondary."
Reason to dismiss C, I think is: it is definitely a tempting choice because Stave's criticism on Stone's contention definitely gives off an impression that women had less rights; this is what the paragraph is trying to make us infer based on the criticism, not what it is trying to do in terms of structure.
