A product that represents a clear technological advance over competing products can generally command a high price. Because technological advances tend to be quickly surpassed and companies want to make large profits while they still can, many companies charge the greatest price the market will bear when they have such a product.  But large profits on the new product will give competitors a strong incentive to quickly match the new product’s capabilities.  Consequently, the strategy to maximize overall profit from a new product is to charge less than the greatest possible price.

T-9-Q3. 支持
Business Consultant: some corporations shun the use of executive titles because they fear that the use of titles indicating position in the corporation tends to inhibit communication up and down the corporate hierarchy. Since an executive who uses a title is treated with more respect by outsiders, however, use of a title can facilitate an executive’s dealings with external businesses. The obvious compromise is for these executives to use their corporate titles externally but not internally, since even if it is widely known that the corporation’s executives use executive titles outside their organization, this knowledge does not by itself inhibit communication within the corporation.

In the consultant’s reasoning, the two portions in boldface play which of the following roles?

A.        The first presents an obstacle to achieving a certain goal; the second presents a reason for considering that goal to be undesirable.
B.        The first is a consideration that has led to the adoption of a certain strategy; the second presents a reason against adopting that strategy.
C.        The first describes a concern that the consultant dismisses as insignificant; the second is a consideration that serves as the basis for that dismissal.
D.        The first is a belief for which the consultant offers support; the second is part of that support.
E.        The first is a belief against which evidence is offered; the second is part of the evidence offered against that belief.

T-4-Q19（在filling blanks里也出现过）
Aroca City currently funds its public schools through taxes on property. In place of this system, the city plans to introduce a sales tax of three percent on all retail sales in the city. Critics protest that three percent of current retail sales falls short of the amount raised for schools by property taxes. The critics are correct on this point. Nevertheless, implementing the plan will probably not reduce the money going to Aroca’s schools. Several large retailers have selected Aroca City as the site for huge new stores, and these are certain to draw large numbers of shoppers from neighboring municipalities, where sales are taxed at rates of six percent and more. In consequence, retail sales in Aroca City are bound to increase substantially.

In the argument given, the two potions in boldface play which of the following roles?
A.        The first is an objection that has been raised against a certain plan; the second is a prediction that, if accurate, undermines the force of that objection.
B.        The first is a criticism, endorsed by the argument, of a funding plan; the second is a point the argument makes in favor of adopting a alternative plan.
C.        The first is a criticism, endorsed by the argument, of a funding plan; the second is the main reason cited by the argument for its endorsement of the criticism.
D.        The first is a claim that the argument seeks to refute; the second is the main point used by the argument to show that the claim is false. （The argument here is not intended to refute the claim itself, but to point out that though the claim of critics is right at this moment, it cannot sufficiently refute the adoption of the plan.）
E.        The first is a claim that the argument accepts with certain reservations; the second presents that claim in a rewarding that is not subject to those reservations.

T-4-Q32

GWD29-Q28:
Astronomer:  Observations of the Shoemaker-Levi comet on its collision course with Jupiter showed that the comet broke into fragments before entering Jupiter’s atmosphere in 1994, but they did not show how big those fragments were.  Nevertheless, some indication of their size can be inferred from spectrographic analyses of Jupiter’s outer atmosphere.  After the fragments’ entry, these analyses revealed unprecedented traces of sulfur.  The fragments themselves almost certainly contained no sulfur, but astronomers believe that the cloud layer below Jupiter’s outer atmosphere does contain sulfur.  Since sulfur would have seeped into the outer atmosphere if comet fragments had penetrated this cloud layer, it is likely that some of the fragments were at least large enough to have passed through Jupiter’s outer atmosphere without being burned up.

In the astronomer’s argument, the two portions in boldface play which of the following roles?

A.        The first is a claim that the astronomer seeks to show is true; the second acknowledges a consideration that weighs against the truth of that claim.
B.        The first is a claim that the astronomer seeks to show is true; the second provides evidence in support of the truth of that claim.
C.        The first and the second are each considerations advanced in support of the conclusion of the argument.
D.        The first provides evidence in support of the conclusion of the argument; the second is that conclusion.
E.        The first is a circumstance for which the astronomer seeks to provide an explanation; the second acknowledges a consideration that weighs against the explanation provided by the astronomer.

Q 24:
Many winemakers use cork stoppers; but cork stoppers can leak, crumble, or become
moldy, so that those winemakers must often discard a significant proportion of their
inventory of bottled wine. 背景事实 Bottlemaster plastic stoppers, which cannot leak, crumble, or mold, have long been available to winemakers, at a price slightly higher than that of traditional cork stoppers. 背景事实Cork prices, however, are expected to rise dramatically in the near future. 证据 Clearly, therefore, winemakers who still use cork but wish to keep production costs from rising will be forced to reconsider plastic stoppers. 次结论 And since the wine-buying public’s association of plastic stoppers with poor-quality wine is weakening, 支持there is an excellent chance that the Bottlemaster plastic stopper will gain an increased share of the marked for wine-bottle stoppers. 结论

GWD-12-Q33**: Boldface
Several of a certain bank’s top executives have recently been purchasing shares in their own bank.  This activity has occasioned some surprise, since it is widely believed that the bank, carrying a large number of bad loans, is on the brink of collapse. 事实 Since the executives are well placed to know their bank’s true condition, it might seem that their share purchases show that the danger of collapse is exaggerated. 因果推论 However, the available information about the bank’s condition is from reliable and informed sources, and corporate executives do sometimes buy shares in their own company in a calculated attempt to calm worries about their company’s condition. 证据 On balance, therefore, it is likely that the executives of the bank are following this example.

Editorial:
An arrest made by a Midville police officer is provisional until the officer has taken the suspect to the police station and the watch commander has officially approved the arrest. Such approval is denied if the commander judges that the evidence on which the provisional arrest is based is insufficient. A government efficiency expert has found that almost all provisional arrests meet standards for adequacy of evidence that watch commanders enforce. The expert therefore recommends that the watch commander’s approval should no longer be required since the officers’ time spent obtaining approval is largely wasted. This recommendation should be rejected as dangerous, however, since there is no assurance that the watch commanders’ standards will continue to be observed once approval is no longer required.

GWD-9-Q30: Boldface
Criminologist: Some legislators advocate mandating a sentence of life（终身监禁） in prison for anyone who, having twice served sentences for serious crimes, is subsequently convicted of a third serious crime. These legislators argue that such a policy would reduce crime dramatically, since it would take people with a proven tendency to commit crimes off the streets permanently. What this reasoning overlooks, however, is that people old enough to have served two prison sentences for serious crimes rarely commit more than one subsequent crime. Filling our prisons with such individuals would have exactly the opposite of the desired effect, since it would limit our ability to incarcerate younger criminals, who commit a far greater proportion of serious crimes.

C. The first is the main conclusion of the argument; the second is an objection that has been raised against that conclusion.
