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?

seek an solution of this gwd cr problem,who can tell me why?

From 1980 to 1989, total consumption of fish in the country of Jurania increased by 4.5 percent, and total consumption of poultry products there increased by 9.0 percent.  During the same period, the population of Jurania increased by 6 percent, in part due to immigration to Jurania from other countries in the region.

 

If the statements above are true, which of the following must also be true on the basis of them?

 

  1. During the 1980’s in Jurania, profits of wholesale distributors of poultry products increased at a greater rate than did profits of wholesale distributors of fish.
  2. For people who immigrated to Jurania during the 1980’s, fish was less likely to be a major part of their diet than was poultry.
  3. In 1989 Juranians consumed twice as much poultry as fish.
  4. For a significant proportion of Jurania’s population, both fish and poultry products were a regular part of their diet during the 1980’s.
  5. Per capita consumption of fish in Jurania was lower in 1989 than in 1980.

the key is E,but why , expecting  an explanation,thank u

here is one cr question more!

Q14:

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?

 

  1. 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.
  2. Hotels built since 1930 can generally accommodate more guests than those built before 1930.
  3. The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930.
  4. The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.
  5. The average length of apprenticeship for carpenters has declined significantly since 1930.

the key is D, i am still confused by it? why?

Problem 1:

E is correct, fish = X( # in 1980) * (1+4.5%), population= Y(# in 1980)*(1+6%)

then fish/population(1989) < X/Y

Problem 2:

D. saying the sample the author investigated was of better quality among all at the era, so better ones have been preserved till now, while coarse ones were demolished.
