Advertisement: Ten years ago, the Cormond Hotel's lobby was carpeted with Duratex carpet while the lobby of a nearby hotel was being carpeted with our competitor's most durable carpet. Today, after a decade in which the two hotels have had similar amounts of foot traffic through their lobbies, that other hotel is having to replace the worn-out carpeting near its lobby entrances, whereas the Cormond's Duratex carpeting has years of wear left in it.
Which of the following, if true, most seriously weakens the force of the advertisement's evidence for concluding that Duratex carpet is more durable than the carpet of its competitor?
AThe lobby of the Cormond Hotel has five different entrances, but the lobby of the other hotel has only two.BThe carpet of the Cormond Hotel's lobby is not the most durable carpet that Duratex manufactures.
CThe other hotel has a popular restaurant that can be reached from outside without walking through the hotel lobby.
DThe carpet that is being used to replace carpeting near the other hotel's lobby entrances is not Duratex carpet.
EThere is a third hotel near the other two that has not replaced the Duratex carpet in its lobby for more than 15 years.
正确答案是A
选项B在网上有的解释是增强，但是在kkk的老师那里解释是循环论证。
理由如下：希尔顿的地毯不是the most durable的都比对手的耐磨+希尔顿的地毯比对手的耐磨------>增强；（把结论当成事实去用，所以循环）
但是我个人觉得这个选项的逻辑链是：希尔顿的地毯不是the most durable的都比对手的耐磨+对手的地毯换了，希尔顿的地毯没有换--->希尔顿的地毯更耐磨（很明显的就是增强啊）本人感觉老师说错了，求各位NN解答。
