Hi Dustin, thank you for your question!
Evidence of the consequences of each extreme view in the last paragraph can be found in the sentences beginning with "on the one hand" and "on the other hand". In these lines, we can find examples of what formal reasoning had "led to" as well as what substantive reasoning has "resulted in", which are the consequences (or effects) of the extreme interpretations. Colloquially, the word consequences is oftentimes used in a negative context, but here, it may be useful to consider how the word on its own does not always imply negative effects! With this in mind, we can see how the final paragraph fits nicely within answer choice (A), as the last paragraph presents the impact of two extreme types of legal reasoning.
Answer choices (D) and (E), on the other hand, aren't entirely provable by the text of the last paragraph. If we look at answer choice (D), we see that this answer discusses "how characterizations..." "...can become convoluted and inaccurate." But if we look to the last paragraph, there's no discussion of
how characterizations of legal reasoning become inaccurate. A similar issue presents itself with answer choice (E)'s mention of "only partially correct." While it may be the case that the author doesn't believe extreme interpretations to be fully accurate, such a belief is not contained within the last paragraph. The author does not discuss any partially correct or incorrect components of each type of legal reasoning, nor does the author indicate that the legal scholars are incorrect in their extreme examples. So, we can eliminate both of these!
I hope this helps!
