I am slightly frustrated by this question because each answer seems to be slightly off to be the right answer. The least offensive being the correct answer, B, but I still don't see it supported by the passage...
I easily excluded:
A -- passage doesn't specify which theory was dominant and no implication that anything was abandoned
D -- there doesn't seem to have been a debate on pros and cons
E -- no controversial theory
Between C and D, I had issues with:
C: the word "novel" -- why is Rawls theory a novel way? Because it offers an alternative to utilitarianism? And what is the problem? Is it the question in paragraph two about knowing what justice requires? That didn't seem evident to me and was not something I picked up under the time constraint of the section...
D: I ultimately picked this one. I had issues with "historical development" as it really didn't seem like it but I thought perhaps it was justified because of the organization of the "pre-Rawls's theory" in the first paragraph and then Rawls's theory. Was this too far of a stretch to make?
Any advice on how to approach this problem would be greatly appreciated. Thank you!
