Most of people tend to just ignore (a)
But as we can infer in (E) ( Receive higher scores on standardized test = improve student performance ), we can infer that what we try to fix is a certain problem related with "improving Student performance"
In (A) If they merely attract the best performing student then It not only doesn`t have positive effects on improving performance but also can weaken the argument.
Please let me know if there`s a logical problem.
Thanks.
