The only reason I can select D is because all other options are either irrelevant or strengthening the argument. So its only by elimination. I see no explanation valid enough for D to be an option.

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.
I dont know the answer, Kindly explain along with the right answer


Choice D is the correct one because it explain that the building which was built in good quality less likely to be collapsed than the one which was built in worse quality. So, we do not know how many buildings less in quality are collapsed before 1930. If there are many buildings are collapsed before 1930 because of the low quality, we cannot conclude that the skill in carpenter before 1930 are better than the skills in carpenter since 1930.

hi Sauravdas,

D does definitely weaken, because it says that buildings built with high quality are more likely to remain in use.

SO

The buildings from pre 1930 are likely to only be a small section of all buildings that were ever built pre 1930 and only the good ones survive. So not all pre 1930 buildings would have had such high quality work.

Hope that helps.

James

Why E is not correct?

E says that length of apprenticeship has declined after 1930 and so we can infer that if every other thing remain same, then the care, skill and effort must be enhanced after 1930 for the same quality of hotel.

Although it's true that by POE you can eliminate all other answers quite easily, IMO, D has very strong logic.

The stem:

Author visits hotels built BEFORE 1930 and AFTER 1930, and sees that carpentry is of higher quality in MORE hotels built before 1930 than built after.

Author CONCLUDES that masters who made carpets for hotels before 1930 were more skillful than those who made carpets for hotels after 1930.

Weaken the conclusion:

D. If carpentry is of WORSE quality in a hotel, then the odds that the hotel will be abandoned and, ultimately, demolished are HIGHER.

THEREFORE: The author cannot objectively CONCLUDE that masters who made carpets for hotels before 1930 were more skillful, BECAUSE he is most probably comparing the residual number of hotels built before 1930 (that were not demolished because they had good carpentry) with the hotels built after 1930, which include hotels that have bad carpentry, but weren't yet demolished because not enough time has elapsed for that to happen.


I hope the answer is exhaustively comprehensive and I'm sorry if my grammar is a bit odd (not english native). I've been reading this forum for a while and decided to register today:) GMAT in 1 week! Good luck everyone.

The writer assumes that 'All the carpentry done during 1930...or during a certain era...was good'....he writes with a 'those good old days...' sense.

Whatever 'Retro' he finds he assumes to be good and unique (perhaps.)

He lives no room for the facts that

1. There could be many buildings in the 1930's which used low quality material and wre eventually demolished.

2. Thr could be many buildings with good carpentry work in present era, which he might have never visited.

The 'samples' he took on which he assumes a certain conclusion are not sufficient.............D highlights the same.

It mentions that only those buildings with good carpentry survived......thus highlighting point 1.

Let me know it was helpful.

ANS D- I need to find a reason to weaken this conclusion. Maybe only slightly or indirectly.

Say there are 100 such pre-1930 old hotels. 90 of them have been demolished because the carpentry was bad

say there are 40 new hotels. Out of the 40 may be 35 hotels have a inferior quality carpentry.

So there are 10 old hotels.....> good carpentry
There are 35 new ones.........> Bad carpentry

Can I conclude that the old hotel is better than the new??

reasons to eliminate A B C & E are convincing :-)

Though a tough que to choose "D" as correct choice

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

We want to weaken the argument that carpenters before 1930 were better than carpenters after 1930.

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. The writer isn't comparing hotels to other buildings - irrelevant.

B. Hotels built since 1930 can generally accommodate more guests than those built before 1930. Irrelevant

C. The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930. STRENGTHENS the argument - if both sets of carpenters have the same quality tools, then the pre-1930's carpenters were probably doing better work with those tools

D. The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished. Makes sense - it's not that every single hotel built before 1930 was better than the ones built after, but instead that the VERY BEST hotels are still around, while the lesser ones have long since been demolished. The proportion of badly built hotels before 1930 could have been much higher than it is now, but all of the bad ones have been demolished and replaced with modern buildings, so the writer is only seeing the best of the best that were built.

E. The average length of apprenticeship for carpenters has declined significantly since 1930. Would strengthen the argument - carpenters train less now than they used to.


I dont know the answer, Kindly explain along with the right answer


Why it is now E ? why is E irrelevant .. its telling the bad quality work after 1930 is cause of length of apprenticeship .. not because carpenters lack in skill or cared less ..

consider it a cause and effect .. more care and skill >>>>> good furniture ... now I introduce something else, hence it should weaken it .. isnt it ?
