CR题求助！

Kopke: In the past ten years, most of the new clothes that I have purchased have fallen apart within a few short years. However, all of the clothes that I have purchased at vintage clothing shops are still in excellent condition, despite the fact that they were all over thirty years old at the time that I bought them. Clearly, clothes are not manufactured as well today as they were when those vintage clothes were made.
Which of the following is a weakness in the argument above?
A.        It fails to demonstrate that the clothes manufactured thirty years ago were of higher quality than clothes of all other era.
B.        It neglects the possibility that the clothes of thirty years ago, when prices are adjusted for inflation, cost more than clothes manufactured today.
C.        It confuses the number of clothing items sold with the proportion of those items that are no longer useful.
D.        It does not explain why clothing manufacturing standards have fallen over item.
E.        It fails to take into account clothes made over thirty years ago that are no longer fit for sale.


有没有大神可以帮我解释解释B选项，我的理解是成本决定一件衣服的质量，那如果这些30年前的复古服装制作成本要比现在衣服要来的高，不是就不能比较现在制作服装技术和过去的技术了吗，因为不是一个档次的东西，不是吗？

B实际上加强了结论。你对成本的理解是对的，成本高，质量就好。但是题目没有提到制作技术，只是说了制作的结果是过去的比现在的好。B为这种现象提供了一个合理的原因，因此加强了结论。

这道题题干的结论来自于作者的观察，所以你要攻击的是作者观察和结论的link。其实是一个sample size的问题，作者说买到的旧衣服质量都好，但是没买到的呢？E就说了很多旧衣服已经不适合销售了，意思就是早就坏了，直接攻击了作者旧衣服质量好的结论。

同意！如同阁下所说， 我结论句理解确实有误，还需加强基本的阅读理解能力，感谢！！
