Publicly available records indicate that Yorco employs roughly the same number
33、 of such hourly wage workers as Zortech does but spends a far higher total sum per year on wages for such workers.

36、und-raisers succeeded in getting donations from 80 percent of the potential donors they contacted. This success rate, exceptionally high for university fund-raisers, does not indicate that they were doing a good job. On the contrary, since the people most likely to donate are those who have donated
37、in the past, good fund-raisers constantly try less-likely prospects in an effort to expand the donor base. The high success rate shows insufficient canvassing effort.Which of the following, if true, provides more support for the argument?A. Smithtown Universitys fund-raisers were successful in their
38、 contacts with potential donors who had never given before about as frequently as were fund-raisers for other universities in their contacts with such people.B. This year the average size of the donations to Smithtown University from new donors when the universitys fund-raisers had contacted was lar
39、ger than the average size of donations from donors who had given to the university before.C. This year most of the donations that came to Smithtown University from people who had previously donated to it were made without the universitys fund-raisers having made any contact with the donors.D. The ma
40、jority of the donations that fund-raisers succeeded in getting for Smithtown University this year were from donors who had never given to the university before.E. More than half of the money raised by Smithtown Universitys fund-raisers came from donors who had never previously donated to the univers
41、ity. Answer: Q17:The quality of unrefined olive oil is not actually defined in terms of acidity, yet extensive tests have shown that the less free oleic acid an unrefined olive oil contains per liter, the higher its quality. The proportion of free oleic acid that an olive oil contains is an accurate
42、 measure of the oils acidity.If the statements above are all true, which of the following conclusions is best supported by them?A. When an olive oil is refined, the concentration of oleic acid in the oil is reduced.B. The quality of an unrefined olive oil can be determined only by accurately measuri
43、ng its acidity.C. If an unrefined olive oil is intermediate in acidity between two other unrefined olive oils, it will also be intermediate between them in quality.D. Free oleic acid is the only acid that unrefined olive oil contains.E. People who judge the quality of unrefined olive oils actually j
44、udge those oils by their acidity, which the judges can taste. Answer: Q19:Sunflowers growing in pots were placed, with their roots submerged, in the pond contaminated with radioactive elements. The sunflowers kept growing; in the process, they absorbed radioactive elements. Within twelve days, 85 pe
45、rcent of the radioactive elements were removed from the water, which is no less than can be accomplished with the much more expensive conventional filtration techniques. Scientists therefore propose using sunflowers for decontamination wherever there are radioactively contaminated ponds.Which of the following, if true, points to a limitation on the applicability of the proposed method of decontamination?A. Some plants other than sunflowers can also remove radioactive elements from water.B. The water in many ponds contaminated with radioactive elements is so
