I think A also weakens the argument

If the carpentry in only the hotels is good then there is a possibility that only a few number of carpenters specialized in hotel carpentry were good(I'm assuming that majority of the carpenters, who were pathetic, in 1930s worked for houses, stores etc - makes sense because there must have been hardly a hand few hotels in that period)

So, the author's point of comparison is illogical - he cannot compare only a handful of carpenters of one era with the ones in some other era and make a conclusion about the carpenters as a whole

Cheers,
Unplugged

The person who is making the staement is only talking about Hotels and the carpentry he observed in hotels that he visited

Survivorship bias - so D.

The good hotels are overrepresented in the pre-1930s pool, becuase the bad ones got demolished. In the post 1930s pool (1930 to 2010), the bad to good ratio is not as skewed - since the recent bad ones are still in the sample.

Hi Guys, Thanks for the explanation to every option. I am however not convinced as to how D can be the correct answer. Here is my reasoning....

D - in D, you are comparing hotels that are still standing to hotels that were demolished. It makes sense to me that hotels with good carpentary were least likely to be demolished, so the carpenters who made them must have done a good job. On the other hand, the ones that were demolished lacked this sort of carpentary. Now if the author has not seen the ones that were demolished, how can he comment on the skill and hard work of the carpenters who made such hotels? Agreed....But i think we are missing something in this explanation.

Author compares hotels (that are standing - because he visited them) before and after 1930. He isnt even bothered about the quality of carpentary in the hotels that were demolished. So he is comparing GOOD vs EXCELLENT carpentary that was used in the hotels that are still standing. That makes option D do no good.

Please explain if ive missed something here...........thanks

i am not happy with the answer D
I choose E

as explained by someone above -->

D) This one says that a building with lower quality carpentry is more likely to be destroyed. Obviously, hotels built before 1930 have had more time to be destroyed than hotels built afterwards. THIS weakens the argument; it says that the guidebook writer is much less likely to SEE the hotels which were built with bad carpentry before 1930, because those are most likely to have disappeared. Consequently, the hotels STILL STANDING which were built before 1930 may not be a representative sample of all hotels which were built back then. Now we can see the assumption, which is that the hotels seen by the writer are representative of both the pre-1930 and the post-1930 time periods. (D) undermines that assumption, and weakens the argument.

how can we assume above ??

I find the question weird ,whats the source of question

ok i understood now really nice explanation by someone above ---->

D. The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished. I'LL GO WITH THIS ONE!! If this is true, it means that only the hotels built with the best carpentry are still up and operating; the hotels built with bad carperntry have been demolished, and thus the author hasn't had the opportunity to visit them and see the job made by less skilled carpenters working in hotels before 1930.

To me, it looks like option B for the reason that if the hotel can accommodate more guests, chances are that more guests usually got accommodated and resulted into more use of carpentry work and faster deterioration of quality.


I also thought in the same way. B seems the correct one.

The answer is very clearly D. The conclusion is based upon the pre-1930s hotels seen TODAY. However, there could be many hotels with poor carpentry that have not survived to the present day, so the author has a skewed perception of pre-1930s hotel carpentry. D very clearly addressed this.

Guidebook writer: I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward. Clearly carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.

Which of the following, if true, most seriously weakens the guidebook writer’s argument?

(A) The quality of original carpentry in hotels is generally far superior to the quality of original carpentry in other structures, such as houses and stores.
(B) Hotels built since 1930 can generally accommodate more guests than those built before 1930.
(C) The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930.
(D) The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.
(E) The average length of apprenticeship for carpenters has declined significantly since 1930.


This question could be categorized as a weaken the argument question or as a flawed argument question.

The Guidebook writer is trying to present a statistical argument, but fails to recognize that the SAMPLE is not representative of the ENTIRE POPULATION.

The SAMPLE consists of pre-1930's hotels that are still standing
The writer uses this sample to make a conclusion about ALL hotels built before 1930 (hotels that are still standing and those that are no longer standing)
So, there's already a problem with the argument, since it's quite possible that the carpentry in many pre-1930 hotels was so awful that those hotels fell apart very quickly.
So, just because the pre-1930's hotels that are still standing have great carpentry, we can't then make sweeping conclusions about the carpentry in ALL pre-1930's hotels

Answer choice D essentially says "the better the carpentry, the greater the chances of a hotel's survival"
It points out the possibility that many pre-1930's hotels could have had bad carpentry and, thus, had to be demolished.

Cheers,
Brent
