关于逻辑类比题

Vicky0722

• 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?

• 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.
  

这一题我一开始选的是C， Helr的逻辑笔记对C错的解释是因为这个选项只提到了The Other hotel, 所以想问一下，是不是类比题如果用A和B的difference削弱，选项里一定要提到A和B? 像选项C，我们虽然知道The other hotel的情况，但不知道Cormond hotel是否也有一个这样popular 的餐厅，所以不能说就是difference?
不知道我的理解是否正确，感谢各位指正！
