【单选题】Government deregulation of the long-distance telephone business has resulted in increased competition among telephone carriers, thus resulting in lower prices for consumers. This process, however, will ultimately result in lower-quality service for consumers, because as the telephone carriers drop their prices to compete with one another for customers, they will be forced to cut corners on non-essential items like customer service. Which of the following, if true, casts the most doubt on the argument that government deregulation of the telephone business will result in lower-quality customer service
A、Technological advances have decreased the cost of providing long-distance telephone service to less than one-half of its cost prior to deregulation.
B、In a customer survey regarding the electric utility business, another industry that recently went through deregulation, surveyors found that customer dissatisfaction with service was 30 percent higher than prior to deregulation.
C、Customers have listed poor customer service as their number one reason for switching from one long-distance telephone service provider to another.
D、Some companies have decreased the cost of customer service by installing automated telephone response systems that eliminate the need for expensive live employees.
E、The greatest competition for long-distance telephone service providers will come not from traditional telephone companies, but from cellular telephone service providers.

Pretty much everybody agrees that clean air is a good thing, rightEvidently not so. Since the 1960s, when people started talking about clean air in the first place, theAmerican energy industry, which includes coal companies, oil companies, and utility companies, has dragged its heels on every initiative to improve the quality of the air we breathe.Even after theCleanAirAct of 1970 and its amendments in 1977 and 1990 made it clear that controlling air pollution is a national priority, these companies have found tricks and loopholes to avoid compliance.
Perhaps the most egregious loophole is the one that allows older power plants to disregard limits on sulfux dioxide emissions until they undergo a major renovation, at which point they have to comply. Sulfur dioxide from coal-burning power plants is the primary cause of acid rain in NorthAmericA、TheCleanAirAct states that when coal-burning power plants upgrade their equipment, they must then comply with sulfur dioxide limitations by either installing scrubbing equipment that cleans the emissions or using fuel with lower sulfur content. The law tied the timing of compliance to major renovations in order to give power plants a grace period in which to comply. Many power plants, however, have exploited a loophole in this law by instituting a series of "minor" renovations that, in effect, upgrade their equipment without requiring them to comply with theCleanAirAct. Some plants have cheated the system by undergoing "minor" renovations for decades.
The power companies claim that they have to resort to these underhanded measures because the cost of compliance with theCleanAirAct is too high.And if everyone else is cheating the system, why should they have to install costly sulfur dioxide scrubbers
This cost argument falls apart upon scrutiny. Since 1977, more than 400 power plants across the country have managed to comply with the restrictions and are still making money. The sulfur dioxide scrubbing equipment has turned out to be far less expensive than the power industry naysayers claimed it would be. Many power plants have even complied with the emissions limits and reduced their operating costs by switching from high-sulfurAppalachian coal to the low-sulfur coal produced in western states such as Wyoming and Idaho. Western coal is not only cleaner than eastern coal, but also, because it is generally closer to the surface, as much as 30 percent less expensive to extract.
Clearly, the costs of compliance with theCleanAirAct can be justified, but if these companies were honest, such justifications would not have to be made. If they were honest, they would acknowledge the costs of not complying: the health costs of increased rates of asthma and lung cancer in high-emissions areas; the environmental costs of acid-scarred forests and lakes; the aesthetic costs of a haze of sulfur dioxide cutting visibility across the eastern United States to only half of what it was in pre-industrial times. When you look at the true costs you have to ask, is any cost too high for clean air
According to information given in the passage, which of the following statements presents the most accurate comparison of an average ton of coal from Wyoming with an average ton of coal from theAppalachian range in West Virginia
A、The former is cheaper and has higher sulfur content than the latter.
B、The latter is found closer to the surface and contains more sulfur than the former.
C、The former can help coal-burning power plants meet limits on sulfur dioxide emissions and costs more than the latter.
D、The latter generates more energy per pound of coa

The MegaTekCorporation’s vice president of marketing made the following statement to the company’s board of directors:
MegaTek has been losing market share to UltraCorp for three years straight.Customer surveys suggest that consumers perceive UltraCorp products to be of higher quality than those produced by MegaTek. MegaTek spends more annually on research and development than UltraCorp does, and it pays its employees a higher average salary, so we do not believe that our products are actually inferior; rather, the perception is due to the fact that UltraCorp charges higher prices and spends more money on advertising. In order to regain the lost market share from UltraCorp, MegaTek should raise its prices and devote more money to advertising.
Discuss how well reasoned you find this argument. In your discussion, be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative examples or counterexamples might weaken the conclusion. You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it more logically sound, and what, if anything, would help you better evaluate its conclusion.
