Explanation

This is a tricky passage. It talks about the controversies that surround history. It seems that even old history can still get people riled up and there are bound to be opposing views.
As always, pay attention to trigger words. The second sentence says, and yet there are lots of different views. This is a change in direction, so one would think there would only be one view.

So the second blank should say something like past or over. Free from works the best. Since everything is being argued, we need something negative or argumentative for the last blank.

That knocks out mellifluousness and objectivity. The first blank speculates on whether or not historical arguments are ever over. Apolitical is the best stand-in for the end of arguments over history.

Hence option A, E anad I are correct.
