You just gave another topic (The third statement as I said):
1.Whether it is fair to admit underrepresented students with lower test scores?
2.Whether it is beneficial to society as a whole to admit underrepresented students with lower test scores?
Note these are two different questions.
You are complaining about "something already happened". I know something about it but not enough to have an opinion--that would be a discussion another day in a different post.
