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.

   Q21:
   In Teruvia, the quantity of rice produced per year is currently just large enough to satisfy domestic demand.Teruvia’s total rice acreage will not be expanded in the foreseeable future, nor will rice yields per acre increase appreciably.Teruvia’s population, however, will be increasing significantly for years to come.Clearly, therefore, Teruvia will soon have to begin importing rice.
   
   
   Which of the following is an assumption on which the argument depends?
   
   
   
   1. No pronounced trend of decreasing per capita demand for rice is imminent in Teruvia.
      
   2. Not all of the acreage in Teruvia currently planted with rice is well suited to the cultivation of rice.
      
   3. None of the strains of rice grown in Teruvia are exceptionally high-yielding.
      
   4. There are no populated regions in Teruvia in which the population will not increase.
      
   5. There are no major crops other than rice for which domestic production and domestic demand are currently in balance in Teruvia.

   The irradiation of food kills bacteria and thus retards spoilage.However, it also lowers the nutritional value of many foods.For example, irradiation destroys a significant percentage of whatever vitamin B1 a food may contain.Proponents of irradiation point out that irradiation is no worse in this respect than cooking.However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since _______.
   
   
   
   A.many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life
   
   B.it is clear that killing bacteria that may be present on food is not the only effect that irradiation has
   
   C.cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods
   
   D.certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is
   
   E.for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded  答案选择e啊  请帮忙解释下下吧
   
   
   Studies in restaurants show that the tips left by customers who pay their bill in cash tend to be larger when the bill is presented on a tray that bears a credit-card logo.Consumer psychologists hypothesize that simply seeing a credit-card logo makes many credit-card holders willing to spend more because it reminds them that their spending power exceeds the cash they have immediately available.
   
   
   
   Which of the following, if true, most strongly supports the psychologists’ interpretation of the studies?
   
   
   
   A.The effect noted in the studies is not limited to patrons who have credit cards.
   
   B.Patrons who are under financial pressure from their credit-card obligations tend to tip less when presented with a restaurant bill on a tray with credit-card logo than when the tray has no logo.
   
   C.In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards.
   
   D.In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card.
   
   E.The percentage of restaurant bills paid with given brand of credit card increases when that credit card’s logo is displayed on the tray with which the bill is prepared.
