Can anyone explain why Question 37 "Which one of the following situations violates the food labeling regulation?" is MBF and not Rule-Application?

Can anyone explain why question 7 "In the exchange above, the function of Craig's comment is to" is a Method of Reasoning question? And not say, Argument Part?

@catqing In getting this question correct, I relied on eliminating B, C, and E with the idea that the stimulus and D both compare 2 different components in the analysis (employee time vs electricity, goodwill vs losses), instead of just saving money or saving time. Just wondering if this is not a good method

So in this situation, is it important that the right answer choice specifically determine that costs outweigh the benefits? Maybe I misinterpreted, but didn't the overview Parallel lessons state that "whether the concepts are expressed in the positive or negative" isn't important? (This is regarding why B cannot be correct)

J.Y. passing on the torch. Hi Kevin!

Wait, so can anyone spell out what is the difference between rules and principles for our purposes?

Wait am I crazy or are the questions repeats of the questions used in the PSA lessons/practices? This is the first question type that I've noticed the drill contains repeat questions.
