Raisins are made by drying grapes in the sun. Although some of the sugar in the grapes is caramelized in the process, nothing is added. Moreover, the only thing removed from the grapes is the water that evaporates during the drying, and water contains no calories or nutrients. The fact that raisins contain more iron per calorie than grapes do is thus puzzling. Which one of the following, if true, most helps to explain why raisins contain more iron per calorie than do grapes? 注意看问题,还是没有把问题理解清楚(我想成“葡萄干的每卡路里含铁量和葡萄的一样多了”),要弄清楚比较的对象是什么!iron per calorie,跟water无关 (A) Since grapes are bigger than raisins, it takes several bunches of grapes to provide the same amount of iron as a handful of raisins does.
This answer choice explains the question, considering the weight. BA
问题在于葡萄只是比葡萄干的水分多,而水分不含有卡路里和营养物质,所以两者每卡路里的含铁量应该是相同的,削弱问题 (B) Caramelized sugar cannot be digested, so its calories do not count toward the calorie content of raisins.
Caramelized sugar is inside both grapes and raisins, and it will not lose. So this answer choice cannot explain the question.
所以葡萄干的卡路里就比葡萄的要少,这是计算方法的问题!加强问题 (C) The body can absorb iron and other nutrients more quickly from grapes than from raisins because of the relatively high water content of grapes.
How the body absorb these materials is irrelevant. (D) Raisins, but not grapes, are available yearround, so many people get a greater share of their yearly iron intake from raisins than from grapes.
Actually, this answer choice has no effect on the argument. (E) Raisins are often eaten in combination with other iron-containing foods, while grapes are usually eaten by themselves.
How they are eaten is outside the scope of the argument.
105. (29298-!-item-!-188;#058&004042) (GWD 6-Q15) Capuchin monkeys often rub their bodies with a certain type of millipede. Laboratory tests show that secretions from the bodies of these millipedes are rich in two chemicals that are potent mosquito repellents, and mosquitoes carry parasites that debilitate capuchins. Some scientists hypothesize that the monkeys rub their bodies with the millipedes because doing so helps protect them from mosquitoes. Which of the following, if true, provides the most support for the scientists’ hypothesis? A. A single millipede often gets passed around among several capuchins, all of whom rub their bodies with it.
This answer choice cannot strengthen the argument. B. The two chemicals that repel mosquitoes also repel several other varieties of insects.
Other varieties of insects are irrelevant. C. The capuchins rarely rub their bodies with the millipedes except during the rainy season, when mosquito populations are at their peak.
Yes, in this case, it points out the relationship between mosquitoes and millipedes. BA D. Although the capuchins eat several species of insects, they do not eat the type of millipede they use to rub on their bodies.
This answer choice has no effect on the argument. E. The two insect-repelling chemicals in the secretions of the millipedes are carcinogenic for humans but do not appear to be carcinogenic for capuchins.
Actually, it cannot support the conclusion.
106. (31188-!-item-!-188;#058&005724) (GWD 28-Q32) A prominent investor who holds a large stake in the Burton Tool Company has recently claimed that the company is mismanaged. As evidence for this claim, the investor cited the company's failure to slow production in response to a recent rise in its inventory of finished products. It is doubtful whether an investor's sniping at management can ever be anything other than counterproductive, but in this case it is clearly not justified. It is true that an increased inventory of finished products often indicates that production is outstripping demand. In Burton's case it indicates no such thing, however: the increase in inventory is entirely attributable to products that have already been assigned to orders received from customers. In the argument given, the two boldfaced portions play which of the following roles? A. The first provides evidence to support the conclusion of the argument as a whole; the second states that conclusion. B. The first states the conclusion of the argument as a whole; the second states an intermediate conclusion that is drawn in order to support that conclusion. C. The first is the position that the argument as a whole opposes; the second provides evidence against the position being opposed. D. The first states an intermediate conclusion that is drawn in order to support the conclusion of the argument as a whole; the second states the conclusion of the argument as a whole. E. The first and the second both state intermediate conclusions that are drawn in order to support jointly the conclusion of the argument as a whole.
107. (26093-!-item-!-188;#058&001880) (GWD 1-Q40 different type) Until now, only injectable vaccines against influenza have been available. They have been used primarily by older adults, who are at risk for complications from influenza. A new vaccine administered in a nasal spray has proven effective in preventing influenza in children. Since children are significantly more likely than adults to contract and spread influenza, making the new vaccine widely available for children will greatly reduce the spread of influenza across the population. Which of the following, if true, most strengthens the argument? A. If a person receives both the injectable and the nasal-spray vaccine, the two vaccines do not interfere with each other.
But it cannot support the conclusion. B. The new vaccine uses the same mechanism to ward off influenza as injectable vaccines do.
The effect of the new vaccine has been referred in the argument. C. Government subsidies have kept the injectable vaccine affordable for all older adults.
It has nothing to do with the new vaccine. D. Of the older adults who contract influenza, relatively few contract it from children with influenza.
It still cannot strengthen the argument. E. Many parents would be more inclined to have their children vaccinated against influenza if the vaccination did not require an injection.
Yes, in this case, more children will use the new vaccine, thus strengthening the argument. BA
108. (32122-!-item-!-188;#058&006354) (GWD 7-Q41) Magazine Publisher: Our magazine does not have a liberal bias. It is true that when a book review we had commissioned last year turned out to express distinctly conservative views, we did not publish it until we had also obtained a second review that took a strongly liberal position. Clearly, however, our actions demonstrate not a bias in favor of liberal views but rather a commitment to a balanced presentation of diverse opinions. Determining which of the following would be most useful in evaluating the cogency of the magazine publisher's response? A. Whether any other magazines in which the book was reviewed carried more than one review of the book
Other magazines are outside the scope of the argument. B. Whether the magazine publishes unsolicited book reviews as well as those that it has commissioned
Unsolicited or commissioned is irrelevant. C. Whether in the event that a first review commissioned by the magazine takes a clearly liberal position the magazine would make any efforts to obtain further reviews
Yes, in the argument, we can see that the magazine did not publish a review that expressed distinctly conservative views until it received a review that took strongly liberal position. On the other hand, if the magazine fist received the latter review, what would it do will demonstrate whether it is a bias in favor of liberal views or a balanced presentation of diverse opinions. BA D. Whether the book that was the subject of the two reviews was itself written from a clearly conservative or a clearly liberal point of view
Which view was the book that was the subject of the two reviews written from is outside the scope of the argument. E. Whether most of the readers of the magazine regularly read the book reviews that the magazine publishes
Whether most readers read the book reviews is irrelevant.
