Now go back to D. Building still there - > original carpentry is good quality - > it is not the workmanship, but the quality of material. Hence, weakens the claim of high quality of workmanship by the author.

Where does it specify about quality of material? It just says that building is still there because of good work done by workers.

After going back and forth between D and E, I chose E after 1:44. Oops.

Was not happy with the answer. I was btw B and D, choose D because of the word "quality"

Only thing I got to say, grumpyoldman, thank you for the amazing explanation. I understand indeed why it is D.

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

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.

A. is irrelevant- Quality of houses and stores is not being discussed here.

B. While it compares favorably hotels built after 1930, does it praise the carpentary? Is the fact that new hotels can accomodate more people that older ones because of their better carpentary? An assumption we cannot make. A likely trap!

C. Materials were not different- so any difference in carpentary might be attributed to skills- strengthens, or neutral- doesnt weaken definitely

D. Correct option- It is simply saying that if the carpentary is good, it is more likely that the structure will not be demolished or fall out of use, and continue serving as a hotel. But what about probability of mnay of hotels built before 1930, which had bad original carpentary and were demolished or fell into disuse, so that the guidebook author never visited them. In the comparison he makes, therefore, he is comparing only the 'good carpentary' cases of hotels before 1930s with those afte 1930s, and is clearly disregarding many possible examples of bad carpentary before 1930s. Unfair comparison - hence weakening to the argument.

E. Seems to imply that therefore the quality of carpentay skills might be going down- which strengthens rather than weaken the argument

D it is.

D tells us Writer visited only those before-1930-hotels that had better quality of carpentary. Otherwise those hotels would have not in use as hotels at all. Hence it weakens writer's claim

The essence of the argument is that better quality hotels is a result of working with more skill, care, and effort prior to 1930. So we need to find a case that refutes this claim. Look for the option disproving that all buildings in this era were of good quality.

D. The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.

If this is true, then we can't say that all hotels were quality hotels prior to 1930 because there could be thousands built at this time that were of poor qualilty which fell into disuse and were demolished. So it correctly weakens the argument.

for D...if the original carpentry work is better before 1930 than since 1930, then why can't we conclude that the worker before 1930 is better than that after 1930? Even the less quality carpentry could be demolished, we can still get that conclusion since worse carpentry is easier to be demolished...

can anyone help me on this?

Argument: quality of carpentry in old hotels is better than new ones , hence the old carpenters were more skilled than newer.
Missing link : why the old carpentry has good quality?

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

a) - out of scope

b) - less use, more intact build. correct

c) - neutral

d) - Neutral

e) - Strengthens the argument.
