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.
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?

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.


这道题答案为什么选A呢？既然两张地毯上的foot traffic相同，那么有几个entrance并没有影响啊？

注意读题：
other hotel is having to replacethe worn-out carpeting near its lobby entrances

虽然进出的总流量一致，但是入口多的有分流作用，出入每个entrance的人就少了，自然就耐久一些。

同样打100板子，100个人共同承担，就是每人疼一下；1个人自己享受就翘辫子了。
