114. Guidebook writer: I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the orginal 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 orginal 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 signficantly different in quality from the materials available to carpenters working after 1930

d) The better the quality of orginal carpentry in building, the less likely taht building is to fall into disuse and be demolished

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

e) The average length of apprenticeship for carpenters has declined significantly since 1930. (irrelevant - nowhere in the premises it is mentioned that apprenticeship has an effect on the skill of carpenters)

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.

I think there is no correct answer to this question.


Incorrect comparison is a common GMAT error and should be recognized at first sight, In the argument given, author is wrongly assuming a few hotels as representative of the entire hotels of one era, as pointed out by option D.

For example, (if you follow cricket), Sachin is the best cricket player does not implies that India has the best cricket team. Or, If Lionel Messi is the best soccer player, then it does not implies that Argentina has the best soccer team. (no offense to fans, just an example)

I hope this helps.

The answer option D. D States "The better the quality of original carpentry in building, the less likely that building is to fall into disuse and be demolished". Thus the best hotels before 1930 have survived and others have been demolished. And the author is comparing best hotel of period before 1930 with all the hotels made after 1930 period.

A tough one to understand but I got my understanding cleared after going through this thread.

The author says that good buildings are due to nice carpentry. But what if the author is considering only those buildings that are good. Say the old empires had built 100 buildings, out of which 50 still exist today and 50 are demolished. The author, living in today's world can see only 50 today and says that the original carpentry is good and that the carpenters in the old time worked with more skill. But he is not considering those 50 buildings that are demolished because of bad carpentry.

So D holds good.
