I'm having a really hard time with this question and I'm not even sure if I'm correctly understanding what the question is asking.
If anyone can explain why (E) is the answer and why (B) is wrong, I'd really appreciate it.

Sure, I took this PT yesterday and got the answer correct. The question is dealing with what type of historical study African-American historians in the era described in the passage would conduct. So basically - what kind of study would these historians have performed of those enumerated in the answer choices (and with a transnational approach)?

Basically, the passage discusses nationalism, nation-building, the reinvisioning of identity, etc. There are also mentions of diaspora and wanting to identify with Africa as opposed to the USA (due to the oppression and Fourteenth Amendment application shortcomings).

E is correct because the question is asking about the transnational approach they would take (once I saw that word I was like, "Okay, the answer will have to do something with Africa) - collective identity, nation-building, addressing the issues of African diaspora, overturning negative representations of black folks, and reinventing a glorious past are all mentioned in the fourth paragraph and would best be achieved by incorporating traditions common to African cultures which they are trying to look back to and embrace as their own.

B is wrong because the passage doesn't really focus on the treatment of minority populations except in passing. Minority populations is already kind of vague (this passage is specifically talking about black people), and also, these historians did not care about the national characters of the USA or European nations, they were focused on rewriting their own history, discovering their own identity - screw the white folks who wouldn't give them proper citizenship.

Hope this helps. Kind of tired and thus the explanation is a little convoluted.
