题：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 replacethe worn-out carpeting near its lobby entrances, whereas the Cormond's Duratex carpeting has years of wear left in it.
问：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?
选项：A. The lobby of the Cormond Hotel has five different entrances, but the lobby of the other hotel has only two.
B. The carpet of the Cormond Hotel's lobby is not the most durable carpet that Duratex manufactures.
C. The other hotel has a popular restaurant that can be reached from outside without walking through the hotel lobby.
D. The carpet that is being used to replace carpeting near the other hotel's lobby entrances is not Duratex carpet.
E. There is a third hotel near the other two that has not replaced the Duratex carpet in its lobby for more than 15 years.
A是正确答案，因为它指出了两个旅馆的不同点。
我是这样想的，题目给出两个旅馆的相同点（foot traffic），所以按理来说carpet的损坏程度也应该一样。但是题目中的conclusion是两者carpet损坏程度不同，还要削弱。那等于是conclusion是两者carpet损坏程度相同，然后加强？？？那不应该是说两者的共同点吗？ 真的很晕，希望有大神帮我解答一下。 |
