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.

For me this is definitely A. A shows that although there's similar foot-traffic in the lobbies, there's different amounts of traffic in the entrances and provides an explanation as to why. Obviously, if there are the same amount of people walking on fewer paths, those fewer paths will show more wear.

B would strengthen the argument.

I feel C would also strengthen. D and E are irrelevant.

A. The lobby of the Cormond Hotel has five different entrances, but the lobby of the other hotel has only two - Correct, more entrance means less footfall per entrance and hence less wear-tear.

B. The carpet of the Cormond Hotel's lobby is not the most durable carpet that Duratex manufactures - Irrelevant

C. The other hotel has a popular restaurant that can be reached from outside without walking through the hotel lobby - If this is the case it is further strengthening that other hotel's carpet is of poor quality.

D. The carpet that is being used to replace carpeting near the other hotel's lobby entrances is not Duratex carpet - Irrelevant as we do not bother about replacing of carpet after wearing.

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 - OFS.


Kudos please.... :)

A. The lobby of the Cormond Hotel has five different entrances, but the lobby of the other hotel has only two - Correct, more entrance means less footfall per entrance and hence less wear-tear.

Let's say both the hotels have 100 foot traffic each.
Option A states that Cormond Hotel has five different entrances, which means that the no of footsteps on the carpet will be distributed to these 5 entrances(avg=20 [100/5] footstep on each of the carpet per entrance) whereas the lobby of other hotel has two entrance only, which means that more no. of footsteps will be distributed to these 2 entrances only (avg=50 [100/2] footstep on each of the carpet per entrance).
More footstep on each carpet per entrance, therefore more wear tear.
