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.
(8) 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.

The answer is 'D'.

"The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished."....It means that most hotels built before 1930 have been put into disuse or demolished...only a few remain with has been compared with modern hotels(which may or may not have better carpentry).

It is like comparing two scores say 3/3 with 8/10....clearly first ratio is greater,but success rate is more in second as first one ignores failed cases.

I came across this question in OG and at many other places. How does the answer(see spoiler) weaken the argument? Please elaborate. I don't see any of those as weakening the argument.

The argument is saying that carpenters before 1930 are more talented than carpenters after 1930 based on his visits to older hotels. However, in D, it is saying that hotels with bad quality carpentry typically get demolished. In other words, if there was a hotel with bad carpentry prior to 1930, the hotel is probably demolished. The argument is making a conclusion based on observation. The writer is only visiting hotels with good carpentry because the ones with bad carpentry have been demolished.

Thank you very much, this is better than any other explanation given elsewhere, better than even the ones posted in the above link. Great.

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

The same would be applicable to buildings after 1930.
Nowhere does he state that this applies only to building before 1930..

Please let me know your thoughts.

This can be true, but the question asks for an answer that weakens and only D weakens from the choices available

i would like to exxplain in slightly diffrent manner
prior to 1930 the buildings included both good and bad carpentry, but the bad carpentry fell into disuse and demolished and good one remained there,
now in mordern days there are good and bad carpentry and the guidebook writer is comparing good and bad carpentry of mordern times to the good carpentry before 1930
hencethe this comparision is awkward hende D is the ans

can someone pls explain y E is not correct...
since avg apprenticeship decreases-> carpenter less skilled before becoming full fledged carpenter ->after 1930 carpenters less skillful

E strengthens the argument, but we need to find statement that weakens it the most....

E strengthens the argument..coz declined avg length of apprenticeship is the reason why carpenters working in hotels after 1930 work with less skill, care..

D weakens

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.Irreverent as the author compares just hotels
B. Hotels built since 1930 can generally accommodate more guests than those built before 1930. We do not care about accommodation but about skill
C. The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930.Irrelevant- How can materials have anything to do. If at all it supports the authors conclusion that even though the same tools were used older buildings were better made
D. The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished. The very reason that the author could visit these hotels is because the quality of carpentry was good and it withstood the test of time
E. The average length of apprenticeship for carpenters has declined significantly since 1930.Irrelevant


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

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

vaivish, malik, nishant - try using POE and you will narrow down to 1~2 choices.

Irrelevant 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.

Irrelevant. Some ppl might try to relate it - more guests - > more damage. If less damage means better work /quality (but this is stretching it too far in GMAT) B. Hotels built since 1930 can generally accommodate more guests than those built before 1930.

Strengthens coz is material is same, then workmanship has to be better. 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.

Irrelevant E. The average length of apprenticeship for carpenters has declined significantly since 1930.

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.
