How do the airlines expect to prevent commercial plane crashes? Studies have shown that pilot error contributes to two-thirds of all such crashes. To address this problem, the airlines have upgraded their training programs by increasing the hours of classroom instruction and emphasizing communication skills in the cockpit. But it is unrealistic to expect such measures to compensate for pilots' lack of actual flying time. Therefore, the airlines should rethink their training approach to reducing commercial crashes.Which one of the following is an assumption upon which the argument depends?

Op-Ed letter: (Town councils are usually unable to make the right decisions when the town is privy to every vote they cast.) Many citizens are unhappy when the council votes to do things like raise taxes, and many of those unhappy citizens give council-members who vote for tax hikes a difficult time outside of the town meeting. Though (anonymity in voting could give council members the autonomy to vote for legislation that negatively impacts community members), not giving them anonymity makes it impossible for them to vote for legislation that the community really needs.What roles do the two boldface portions play in the letter-writers argument?

Which of the following best completes the passage below?As long as savings deposits are insured by the government, depositors will have no incentive to evaluate the financial strength of a savings bank.

For the writers who first gave feudalism its name, the existence of feudalism presupposed the existence of a noble class. Yet there cannot be a noble class, properly speaking, unless both the titles that indicate superior, noble status and the inheritance of such titles are sanctioned by law. Although feudalism existed in Europe as early as the eighth century, it was not until the twelfth century, when many feudal institutions were in decline, that the hereditary transfer of legally recognized titles of nobility first appeared.The statements above, if true, most strongly support which one of the following claims?

Political Analyst: After the Soviet Union collapsed, some hoped that freedom would encourage Russians to multiply, but as a result of dislocation and insecurity, the Russian population continues to dwindle at the rate of 700,000 a year. The government proposes to address the problem with a wide range of financial incentives, along with investments in improved health care, road safety and the like. These are positive measures, but they have been tried before, to little avail. A better plan to reverse the population decline is to improve the country's governance in both the public and the private sphere. If a greater part of the population participated in important decisions and shared in the country's wealth, then larger families would result. In addition, if corruption and greed among the elite were curbed, public health would improve and average life expectancy would increase.The two boldfaced statements serve what function in the argument above?

People's television-viewing habits could be monitored by having television sets, when on, send out low-level electromagnetic waves that are reflected back to the sets. The reflected waves could then be analyzed to determine how many persons are within the viewing area of the sets. Critics fear adverse health effects of such a monitoring system, but a proponent responds, "The average dose of radiation is less than one chest x-ray. As they watch, viewers won't feel a thing."Which of the following issues would it be most important to resolve in evaluating the dispute concerning the health effects of the proposed system?
