15. People who take what others regard as a ridiculous position should not bother to say, “I mean every word!” For either their position truly is ridiculous, in which case insisting that they are serious about it only exposes them to deeper embarrassment, or else their position has merit, in which case they should meet disbelief with rational argument rather than with assurances of their sincerity.
Which one of the following arguments is most similar in its reasoning to the argument above?
(A) A practice that has been denounced, as poor practice should not be defended on the grounds that “this I show we have always done it.” If the practice is a poor one, so much the worse that is has been extensively used; if it is not poor one, there must be a better reason for engaging in it than inertia
(B) People who are asked why they eat some of the unusual foods they eat some of the unusual foods they eat should not answer, “because that is what I like, “This sort of answer will sound either na?ve or evasive and thus will satisfy no one
(C) People whose taste in clothes is being criticized should not replay, “Every penny I spent on these clothes I earned honestly.” For the issue raise by the critics is not how the money was come by but rather whether it was spent wisely.
(D) Scholars who champion unpopular new theories should not assume that the widespread rejection of their ideas shows that they “must be no the right track.” The truth is that few theories of any consequence are either wholly right or wholly right or wholly wrong and thus there is no substitute for patient works in ascertaining which parts are right.
(E) People who set themselves goals that others denounce as overly ambitious do little to silence their critics if they say, “I can accomplish this if anyone can. “Rather, those people should either admit that their critics are right or not dignify the criticism with any reply.
答案是A,请问题干中的reasoning是什么？感觉题干句子太绕了。搞不清楚在说什么，用费费的难题猜A法居然猜对了。

The reasoning in the argument is that when people try to defend a "unconventional" position, they should not just claim that they are serious about the position. If the position is wrong, what they said make them look worse. If the position is right, they should use some reasoning to defend it, instead of just say "I am serious".

In A, it is the same argument. If they think what they have been doing is right, show some reasoning to defend the practice, instead of say "we always did it that way". If it is wrong, it makes them look bad that they always did things the wrong way. If it is right, they should have some good reasons for doing that.
