I’m happy to help. As always, let’s start with the question stem. We are looking for the answer that best expresses the main point of the passage.
Answer A tells us that main point was that the oath should be reevaluated “to make certain that its fundamental moral rules still apply today.†There are a few indicators that the author does not believe the moral rules still apply, including that the “fixed moral rules†are “incompatible with more flexible modern ideas about ethics.†Instead, we learn at the end of the passage that the main aspect of the oath the author is a fan of is the “core value of beneficence†even if the oath is shaped around “generally acceptable standards of professionalism†rather than the old moral rules.
That is why answer B is a better answer — it focuses on those main points of professionalism and beneficient treatment. I hope this helps! Please let us know if you have further questions.
