Can you please explain why it i C and not D

[Dana D]

Hey Gloria,

We're asked here to complete the argument. It's important to think about the argument structure here - the conclusion is based almost entirely on the proceeding sentence's logic, which is easy to overlook if you don't stop to think about what "this" refers to at the beginning of the last sentence. If we add in that context, the last sentence really says something like "The fact that people are obligated to fulfill duties even when this might be harmful to their self-interest shows that _____".

With that in mind, looking at the answer choices, (D) does not best complete the argument. The stimulus says some rules are more important than others, and those rules become duties, but the conflict between what duties must be prioritized really comes down to a conflict between self-interest and duty. Answer choice (C) addresses this conflict, which makes it the better answer choice.

Hope that helps!
