Thanks for the question! So we’re being asked here for what the author thinks about the legal principle that “a right of recourse arises only if harm accrues” in lines 49-50. Well, since we’re given the line numbers, we should go to them, and read both the lines above and below to make sure we understand the full context in which this phrase is being used.
Luckily for us, our job isn’t too hard here. Take a look at the full sentence, which tells us that “under the law, a right of recourse arise sonly if harm accrues.” So the author thinks that this is “under the law,” which is what (A) tells us, that it’s an established principle of law!
(E) tells us that this legal principle is central to the current means of addressing judicial bias. Sure, it might be part of it, but where are we told that it is central?
Hope this helps! Feel free to ask any other questions that you might have.
