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.

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


to negate, we must prove that the skills of the carpenters did not get worse, or that the hotels which the writer visited were among the few of the ones built before 1930, which were built with high quality carpentry so that to last for a long time. it might be the case that carpets of some hotels from 1930 were not good, and thus, such hotels just simply did not last to live the writer's time...

A - other structures - irrelevant.
B - this might give alternative reason why the conditions of the carpets in hotels built after 1930 are worse. yet, it does not provide evidence that the quality is the same.
C - this actually strengthens the argument. same materials - but quality different. nowadays carpenters - bad.
D - ok, so the hotels built before 1930 are standing still, because they had better quality of carpentry. this means that there were hotels with lower quality, but which did not get to the writer's time... looks good. Now, the writer compares the hotels built before 1930, with exceptionally high quality, with hotels built after 1930, with "standard" quality. we can see that the comparison is not accurate.
E - this one strengthens the argument.

Hi

I still dont understand why D is the correct answer?
Why are we assuming about demolition etc when it clearly says those hotels are still standing. Thats why he could visit them at first place.

The explanation provided for D absolutely do not make any sense. It's a general statement which has no effect on the argument OR it is at least strengthening the carpenters who worked before 1930s.

Couldn't zero in on any answer. POE might get us to D but still it cannot weaken the Original argument in any way.
Debatable question.

I got this wrong, but what a beautiful question! Thought: current year isn't mentioned explicitly. I wonder how things would have changed it it were.

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


This is the logical chain: More skills/care/effort --> better quality of carpentry
If we find somthing else that led to better carpentry we will weaken this conclusion.

Choice D says: Less liklehood that a hotel be demolished <-correlated-> better quality.
- it might be the case that people did not want their hotel to be demolished so they invested in better quality of carpentry.

Hence D is correct

This is a superb question !!
In my 2 cents,
options D introduces the possibility that the hotels with lower carpentry quality were demolished.Thus,the remaining buildings are incomparable since they are not the represent the actual quality of carpentry work.

If this was a strengthen question, can someone confirm if "(E) The average length of apprenticeship for carpenters has declined significantly since 1930" would be the correct answer?
