I just wanted to add how I got to this answer. It happened way too slowly and ate up about 2 minutes off my clock (
) but it happened nonetheless!
The author says "Information about economic rivalry in medicine, women's literacy, and the
control of medical knowledge could add much to our growing understanding of women medical practitioners' role in medieval society." So I thought about these things and went to the questions with that in mind.
(B) is the most analogous to what the author is saying here because it deals directly with the "control of medical knowledge." If we focused on "the effect of social constraints on medieval women's
access to medical education" then this would deal directly with how women were not in control when obtaining medical knowledge - other social constraints held them down!
(A) is wayyyyy too broad. We could be talking about men, women, children, etc. We also don't know if it is talking about medical practitioners. This is all stuff we'd like to have info on.
(C) This is just ludicrous. This isn't relevant to the final paragraph where we are supposed to find this answer.
(D) This, like (C), isn't relevant to the final paragraph, where we are supposed to find this answer.
(E) I think this is a fine answer but not better than (B) because, as others have mentioned, it is a bit too broad. (B) is much more analogous with the text while (E)'s study could have to do with women in the legal world or mothers or whatever.
