A. Ink-jet printers in regular use frequently need new ink cartridges, and Printwell‘s printers only accept Printwell‘s ink
cartridges. B. Unlike some competing companies, Printwell sells all of its printers through retailers, and these retailers‘ costs
account for a sizable proportion of the printers‘ ultimate retail price. C. Some printer manufacturers have been forced to reduce the sale price of their ink-jet printers even more than
Printwell has. D. In the past year, no competing manufacturer of ink-jet printers has had as great an increase in unit sales of printers
as Printwell has. E. In the past year, sales of Printwell‘s ink-jet printers have increased more than sales of any other type of printer
made by Printwell. ------------------------------------------------------------------------------------------------------------ GWD7-Q37:
Escalating worldwide demand for corn has led to a sharp increase in the market price of corn, and corn prices are likely to remain high. Corn is extensive used as feed for livestock, and because profit margins are tight in the livestock business, many farmers are expected to leave the business. With fewer suppliers, meat prices will surely rise. Nonetheless, observers expect an immediate short-term decrease in meat prices.
Which of the following, if true, most helps to justify the observers‘ expectation?
A. The increase in corn prices is due more to a decline in the supply of corn than to a growth in demand for it. B. Generally, farmers who are squeezed out of the livestock business send their livestock to market much earlier than
they otherwise would. C. Some people who ate meat regularly in the past are converting to diets that include little or no meat. D. As meat prices rise, the number of livestock producers is likely to rise again.
E. Livestock producers who stay in the business will start using feed other than corn more extensively than they did in
the past. GWD7-Q38:
Journalist: Well-known businessman Arnold Bergeron has long been popular in the state, and he has often talked about running for governor, but he has never run. However, we have just learned that Bergeron has fulfilled the financial
disclosure requirement for candidacy by submitting a detailed list of his current financial holdings to the election commission. So, it is very likely that Bergeron will be a candidate for governor this year.
The answer to which of the following questions would be most useful in evaluating the journalist‘s argument?
A. Has anybody else who has fulfilled the financial disclosure requirement for the upcoming election reported greater
financial holdings than Bergeron? B. Is submitting a list of holdings the only way to fulfill the election commission‘s financial disclosure requirements? C. Did the information recently obtained by the journalists come directly from the election commission? D. Have Bergeron‘s financial holdings increased in value in recent years?
E. Had Bergeron also fulfilled the financial disclosure requirements for candidacy before any previous gubernatorial
elections? ------------------------------------------------------------------------------------------------------------ GWD7-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 B. Whether the magazine publishes unsolicited book reviews as well as those that it has commissioned
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
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 E. Whether most of the readers of the magazine regularly read the book reviews that the magazine publishes
答案为C
这是EVALUATE题。对答案的两种回答能WEAKEN和SUPPORT原文结论。 如果对C回答是，则支持结论。 对C回答否，则削弱结论。
A：carried more than one review of the book，数量不是问题，问题是性质 B：是否也出版主动送上门来的书评，无关，回答了也没用啊 C：肯定回答，说明在主动寻求平衡；否定回答，说明在消极回避
D：如果原著保守，那么这家报社仍然出版两种书评；如果原著自由，那么这家报社仍然出版两种书评；有什么区别呢？ E：读者读不读是另一回事；无关

GWD-TN-9 GWD-12-Q2:
Scientists are discussing ways to remove excess carbon dioxide from the atmosphere by increasing the amount that is absorbed by plant life. One plan to accomplish this is to establish giant floating seaweed farms in the oceans. When the seaweed plants die, they will be disposed of by being burned for fuel.
Which of the following, if true, would indicate the most serious weakness in the plan above?
A. Some areas of ocean in the Southern Hemisphere do not contain sufficient nutrients to support large seaweed farms. B. When a seaweed plant is burned, it releases an amount of carbon dioxide comparable to the amount it has
absorbed in its lifetime. C. Even if seaweed farms prove effective, some people will be reluctant to switch to this new fuel.
D. Each year about seven billion tons of carbon dioxide are released into the atmosphere but only about five billion
tons are absorbed by plant life. E. Seaweed farms would make more money by farming seaweed to sell as nutritional supplements than by farming
seaweed to sell as fuel. ------------------------------------------------------------------------------------------------------------ GWD-12-Q11:
In general, jobs are harder to get in times of economic recession because many businesses cut back operations. However, any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools. This is because Vargonia has just introduced a legal requirement that education in government-funded schools be available, free of charge, to all Vargonian children regardless of the state of the economy, and that current student-teacher ratios not be exceeded.
Which of the following, if true, most strengthens the argument?
A. The current student-teacher ratio at Vargonia‘s government-funded schools is higher than it was during the most
recent period of economic recession. B. During recent periods when the Vargonian economy has been strong, almost 25 percent of Vargonian children have
attended privately funded schools, many of which charge substantial fees. C. Nearly 20 percent more teachers are currently employed in Vargonia‘s government-funded schools than had been
employed in those schools in the period before the last economic recession.
D. Teachers in Vargonia‘s government-funded schools are well paid relative to teachers in most privately funded
schools in Vargonia, many of which rely heavily on part-time teachers. E. During the last economic recession in Vargonia, the government permanently closed a number of the schools that it
had funded.
One thing I might not make clear is that this is a strengthen question. So a close correlation is not necessary. Only a correlation by common snese is necessary. But I still could not see the relationship by common sense in A and C.
C说的是现在（并不是这次的RECESSION）的老师就业比上次RECESSION前的就业多20%。对原文结论不起任何作用。因为你不知上次RECESSION老师就业情况。B说是最近经济好时25%学生去读私立学校，付高昂的学费，这样将来RECESSION时，就有可能这些学生中的一部分因付不起高昂的学费而去读公立学校，使学生和老师比例更大，对老师的需求也大。从而加强结论：将来RECESSION是公立学校老师不会失业。

Which if the following, if true, most logically completes the argument?
Aroca County‘s public schools are supported primarily by taxes on property. The county plans to eliminate the property tax and support schools with a new three percent sales tax on all retail items sold in the county. Three percent of current retail sales is less than the amount collected through property taxes, but implementation of the plan would not necessarily reduce the amount of money going to Aroca County public schools, because ______.
A. many Aroca County residents have already left the county because of its high property taxes B. a shopping mall likely to draw shoppers from neighboring counties is about to open in Aroca County
C. at least some Aroca County parents are likely to use the money they will save on property taxes to send their
children to private schools not funded by the county D. a significant proportion of parents of Aroca County public school students do not own their homes and consequently
do not pay property taxes E. retailers in Aroca County are not likely to absorb the sales tax by reducing the pretax price of their goods ------------------------------------------------------------------------------------------------------------ GWD-12-Q15:
FastMart, a convenience store chain, is planning to add pancake syrup to the items it sells. FastMart stores do not have shelf space to stock more than one variety of syrup. Surveys of FastMart customers indicate that one-fourth of them prefer low-calorie syrup, while three-fourths prefer regular syrup. Since FastMart‘s highest priority is to maximize sales, the obvious strategy for it is to stock regular syrup.
Which of the following, if true, most seriously weakens the argument?
A. People buying pancake syrup at convenience stores, unlike those buying it at supermarkets, generally buy it only a
few times. B. People who prefer low-calorie syrup generally use about the same amount of syrup on their pancakes as those who
prefer regular syrup. C. Regular syrup does not sell for a higher price per unit than low-calorie syrup.
D. In general, customers who prefer regular syrup will buy low-calorie syrup if regular is unavailable, but those who
prefer low-calorie will not buy regular syrup. E. Sales of syrup are not expected to account for a large proportion of total dollar sales at the average FastMart store.
因为regular syrup=3/4 customer low calorie syrup= 100% customer
agree，因为如果放low calorie syrup的话，喜欢regular syrup的人也会买

Certain genetically modified strains of maize produce a natural insecticide that protects against maize-eating insects. The insecticide occurs throughout the plant, including its pollen. Maize pollen is dispersed by the wind and often blows onto
milkweed plants that grow near maize fields. Caterpillars of monarch butterflies feed exclusively on milkweed leaves. When, in experiments, these caterpillars were fed milkweed leaves dusted with pollen from modified maize plants, they died. Therefore, use of the modified maize inadvertently imperils monarch butterflies. Which of the following, if true, most seriously weakens the argument?
A. Per unit of volume, the natural insecticide produced by the genetically modified maize plants is less toxic to insects
than are many commercial insecticides commonly used on maize plants. B. Standard weed-control practices that have been used by farmers for decades have largely eliminated milkweed
plants from certain areas where monarch-butterfly caterpillars were once common. C. The experiments showed that the caterpillars were not harmed by contact with the pollen from the genetically
modified plants unless they ingested it. D. The maize-eating insects that the natural insecticide protects against do not feed on the pollen of the maize plant. E. Airborne maize pollen tends to collect on the middle leaves of milkweed plants and monarch caterpillars feed only
on the plant‘s tender upper leaves. ----------------------------------------------------------------------------------------------------------- Q21: GWD-13-31
By competing with rodents for seeds, black ants help control rodent populations that pose a public health risk. However, a very aggressive species of blank ant, the Loma ant, which has recently invaded a certain region, has a venomous sting that is often fatal to humans. Therefore, the planned introduction into that region of ant flies, which prey on Loma ants, would benefit public health.
Which of the following, if true, most strengthens the argument?
A. Ant flies do not attack black ants other than Loma ants.
B. Loma ants are less effective than many bird species in competing with rodents for seeds.
C. Certain other species of black ants are more effective than Loma ants in competing with rodents for seeds. D. The sting of Loma ants can also be fatal to rodents.
E. The use of pesticides to control Loma ants could have harmful effects on the environment. GWD-12-Q22:
Denoma, a major consumer-electronics maker, had a sizeable decline in sales revenue for its most recent fiscal year. This result appears surprising, because electronics retailers report that although their overall sales were considerably lower than in the previous year, their sales revenue from Denoma models actually grew, largely thanks to some innovative and popular models that Denoma introduced.
Which of the following, if true, does most to explain the apparently surprising result?
A. Because of the need to educate the public about its new models‘ capabilities, Denoma‘s advertising spending was
higher than normal over the period. B. For the period at issue, Denoma‘s major competitors reported declines in revenue that were, in percentage terms,
greater than Denoma‘s. C. A significant proportion of Denoma‘s revenue comes from making components for other consumer-electronics
manufacturers. D. Unlike some of its major competitors, Denoma has no lines of business outside consumer electronics to provide
revenue when retail sales of consumer electronics are weak. E. During the period, consumer-electronics retailers sold remaining units of Denoma‘s superseded models at prices that
were deeply discounted from those models‘ original prices. ------------------------------------------------------------------------------------------------------------ GWD-12-Q29:
