Why is D correct?

What is the evidence in the passage that supports choice D?

Hi all, This is a great question because this set of passages is a pretty tricky one. For passage A, I would direct your attention to lines 12-15, where the author sets out a principle suggesting that "if it can be shown that following a general rule favoring sincerity produces the most prudential outcomes, then the rule is justified." The fact that a conditional is used here suggests that there exist possible scenarios in which positive benefits result from a lack of judicial sincerity. In passage B, I would direct your attention to lines 51-55. The author asks a pair of rhetorical questions about if the arguments previously presented suggest that judicial deception is never warranted, to which the author answers, "Probably not." By answering in the negative, the author affirms the possibility of positive benefits accruing from judicial deception (a lack of judicial candor). Hope this helps.
