      When trying to identify new technologies that promise to transform the marketplace, market researchers survey the managers of those companies that are developing new technologies. Such managers have an enormous stake in succeeding, so they invariably overstate the potential of their new technologies. Surprisingly, however, market researchers typically do not survey a new technology’s potential buyers, even though it
 is the buyers—not the producers—who will ultimately determine a technology’s commercial success.Which of the following, if true, best accounts for the typical survey practices among market researchers?

      In Stenland, many workers have been complaining
 that they cannot survive on minimum wage, the
 lowest wage an employer is permitted to pay. The government is proposing to raise the minimum wage. Many employers who pay their workers the current minimum wage argue that if it is raised, unemployment will increase because they will no longer be able to afford to employ as many workers.Which of the following, if true in Stenland, most strongly supports the claim that raising the minimum wage there will not have the effects that the employers predict?

      Last year a chain of fast-food restaurants, whose
 menu had always centered on hamburgers, added its first vegetarian sandwich, much lower in fat than the chain’s other offerings. Despite heavy marketing, the new sandwich accounts for a very smallproportion of the chain’s sales. The sandwich’s sales would have to quadruple to cover the costs associated with including it on the menu. Since such an increase is unlikely, the chain would be more profitable if it dropped the sandwich.Which of the following, if true, most seriously weakens the argument?

      Transportation expenses accounted for a large portion
 of the total dollar amount spent on trips for pleasure by residents of the United States in 1997, and about half of the total dollar amount spent on transportation was
 for airfare. However, the large majority of United States residents who took trips for pleasure in 1997 did not travel by airplane but used other means of transportation. If the statements above are true, which of the following must also be true about United States residents who took trips for pleasure in 1997?

      Increased use of incineration is sometimes advocated as a safe way to dispose of chemical waste. But opponents of incineration point to the 40 incidents involving unexpected releases of dangerous chemical agents that were reported just last year at two existing incinerators commissioned to destroy a quantity of chemical waste material. Since designs for proposed new incinerators include no additional means of preventing such releases, leaks will only become more prevalent if use of incineration increases.Which of the following, if true, most seriously weakens the argument?

      Manufacturing plants in Arundia have recently been acquired in substantial numbers by investors from abroad. Arundian politicians are proposing legislative action to stop such investment, justifying the proposal by arguing that foreign investors, opportunistically exploiting a recent fall in the value of the Arundian currency, were able to buy Arundian assets at less than their true value.Which of the following, if true, casts the most serious doubt on the adequacy of the Arundian politicians’ justification for the proposed legislation?

      Because the framers of the United States Constitution (written in 1787) believed that protecting property rights relating to inventions would encourage the new nation’s economic growth, they gave Congress— the national legislature— a constitutional mandate to grant patents for inventions. The resulting patent system has served as a model for those in other nations. Recently, however, scholars have questioned whether the American system helped achieve the framers’ goals. These scholars have contended that from 1794 to roughly 1830, American inventors were unable to enforce property rights because judges were “antipatent” and routinely invalidated patents for arbitrary reasons. This argument is based partly on examination of court decisions in cases where patent holders ("patentees”) brought suit alleging infringement of their patent rights. In the 1820s, for instance, 75 percent of verdicts were decided against the patentee. The proportion of verdicts for the patentee began to increase in the 1830s, suggesting to these scholars that judicial attitudes toward patent rights began shifting then.Not all patent disputes in the early nineteenth century were litigated, however, and litigated cases were not drawn randomly from the population of disputes. Therefore the rate of verdicts in favor of patentees cannot be used by itself to gauge changes in judicial attitudes or enforceability of patent rights. If early judicial decisions were prejudiced against patentees, one might expect that subsequent courts— allegedly more supportive of patent rights— would reject the former legal precedents. But pre-1830 cases have been cited as frequently as later decisions, and they continue to be cited today, suggesting that the early decisions, many of which clearly declared that patent rights were a just recompense for inventive ingenuity, provided a lasting foundation for patent law. The proportion of judicial decisions in favor of patentees began to increase during the 1830s because of a change in the underlying population of cases brought to trial. This change was partly due to an 1836 revision to the patent system: an examination procedure, still in use today, was instituted in which each application is scrutinized for its adherence to patent law. Previously, patents were automatically granted upon payment of a $30 fee.

      The introduction of new drugs into the market is frequently prevented by a shortage of human subjects for the clinical trials needed to show that the drugs are safe and effective. Since the lives and health of people in future generations may depend on treatments that are currently experimental, practicing physicians are morally in the wrong when, in the absence of any treatment proven to be effective, they fail to encourage suitable patients to volunteer for clinical trials.Which of the following, if true, casts most doubt on the conclusion of the argument?

    【OG20-P580-669题】Rainwater contains hydrogen of a heavy form called deuterium. The deuterium content of wood reflects the deuterium content  of rainwater available to trees during their growth. Wood from trees that grew between 16,000 and 24,000 years ago in North America contains significantly more deuterium than wood from trees growing today. But water trapped in several North American caves that formed during that same early period contains significantly less deuterium than rainwater in North America contains today.Which of the following, if true, most helps to reconcile the two findings?

    【OG20-P602-739题】Between 1980 and 2000 the sea otter population of the Aleutian Islands declined precipitously. There were no signs of disease or malnutrition, so there was probably an increase in the number of otters being eaten by predators. Orcas will eat otters when seals, their normal prey, are unavailable, and the Aleutian Islands seal population declined dramatically in the 1980s. Therefore, orcas were most likely the immediate cause of the otter population decline.Which of the following, if true, most strengthens the argument?
