A construction project has been tasked with building a four-lane road from a remote mountain fortress to a major expressway lying at the base of the mountain. The slope leading to the mountain fortress is so precipitous that the only conceivable way to carry out the project is by building the road downhill, since construction equipment is able to move down, but not up, the steep terrain. The foreman has devised the following solution: dismantle each construction vehicle and tie a part upon the back of a donkey, an animal capable of making the steep ascent. The foreman has at his disposal more than 100 donkeys, each of which is capable of making multiple trips up the mountain.
In order for the foreman's plan to be successful, which of the following pieces of information is most important?

Mayor: the commuters from the nearby suburb of Coldstream perennially complain of a difficult commute to our downtown region. To address these concerns, we should install high-speed toll collector on the interstate between here and Coldstream, thus relieving any traffic snarls caused by the hand-operated toll booths. Civil engineer: Over 95% of commuters from Coldstream take local roads, not the interstate, to our downtown region. The civil engineer uses which of the following techniques in responding to the mayor?

Aviation Analyst: To combat human error involved in air traffic control, Miro Jets Inc. has recently installed each of its DC-10 passenger planes with a special anti-collision device. The device alerts the DC-10, via a red light, when another plane is slightly more than three minutes away from a potential collision. The red light comes on and stays on until the approaching plane is safely out of range. Aviation experts at Miro Jet Inc. have determined that three minutes is ample time for a plane to divert its respective flight path to avoid a collision. Therefore, if the red light on the anti-collision device is off, the DC-10 is more than three minutes flying time from any plane. Which of the following, if true, most fundamentally calls into question the aviation analyst's argument?

Lawrence County has seven county run hospitals. Because three privately run hospitals are now in existence in the county, Lawrence has decided to close one of its seven county hospitals, to reduce costs to the county. The county executives want to choose a hospital to close so that its absence has the fewest negative health consequences for citizens of the county. An independent consulting firm, advising the county executives, has recommended closing the hospital with the highest fatality rate. Which of the following, if true, most seriously calls into question the consulting firm's recommendation for the choosing the hospital to close?

Because state sanctions against hunting have been eased, Deersdale Preserve has experienced an influx of hunters in the last several months. During this time, the silvertail fox, a popular target for hunters, has seen a marked decrease in population. Therefore, to prevent the population of silvertail fox—an important apex predator responsible for keeping the Deersdale County's rabbit population in check—from falling even lower, the state should once again place strict sanctions against hunting.Which of the following, if true, most strongly suggests that stricter sanctions against hunting would not have the desired effect?

For years, Pleasanton was a commuter community to industries in Middleburg. The close of several factories in Middleburg has set in motion a wave of mortgage defaults: citizens of Pleasanton are foreclosing on their houses in significant numbers. Many of the mortgages were held by local banks, and these adversely affected banks have been under pressure from their boards to offset the banks' losses. One principal means to recoup these losses is for the banks to raise interest rates, including mortgage rates. If those owning property in Pleasanton continue to default on their mortgages, then the mortgage rates offered by these banks will continue to rise.Which of the following, if true, best supports the conclusion that mortgage rates in Pleasanton will continue to increase?

Along the mudflats of Garantia exist two types of annelids: earthworms and lugworms. Earthworms tend to emerge from the mud early in the morning when there is more moisture and nutrients. As a result, earthworms have access to more nutrients and thus reproduce far faster than the lugworm, which spends much of the day submerged in the mud. Nonetheless, the lugworm population far outnumbers that of the earthworm.Which of the following, if true, helps LEAST to resolve the apparent discrepancy noted above?

The inventor of this laptop claims that it will reduce insurance and security costs at offices, as only authorized users will be able to turn on the laptop, making it a less appealing target for thieves.Which of the following, if true, most supports the company's implementing its plan to develop the prototype?

The following is an excerpt from a campaign speech. Senator Baker: My opponent, Candidate Rothmore, has called for increased taxes to fund programs that help the long-term unemployed of the state. Such action would address an immediate symptom for a select group, without doing much to address the overall problems we all face. Only through lowering taxes can we stimulate the growth of small businesses, which will revitalize the state's whole economy. That, in turn, will result in greater prosperity and in more jobs, including jobs for those who have been unemployed for a while. Through lowering taxes, everyone wins, and those currently unemployed get the best help the economy can provide --- a real job. In the argument, the two portions in boldface play which of the following roles?

Outsourcing, or the allocation of specific aspects of a corporation to a business entity specializing in those areas, has become such an integral part of a company's organizational structure that few question outsourcing's long-term viability. Two recent studies on this topic are no exception; both focus on ways in which outsourcing can be improved. Each, for the most part, discusses different aspects of outsourcing. Yet, there is one area in which the recommendations of both theories overlap somewhat.Peavy chiefly discusses ways in which companies can mitigate the potential negative effects of confidential information reaching competitors. Presently, when a corporation outsources even a small operational function, it must share information pertaining to this function. In other words, the more of its operation a company entrusts to another business entity, the more confidential information that company will have to release. According to Peavy, one way to minimize the negative consequences should any of that information fall into a competitor's hands is to impose stronger penalties on any business entity entrusted with such information, should it divulge that information. However, Peavy is concerned mostly with exploring the effect of increasing the severity of penalties for any one instance of leaked information, and he devotes only one chapter to an existing structural check on such “information leaks”: as a company specializing in outsourcing assumes more clients, its legal liability will increase with each company that becomes a client, an effect, he notes, that becomes more conspicuous the more a company diversifies. Morgan, on the other hand, looks at those business entities that performed the outsourced work. As such entities grow, their ability to provide specialized services to a specific client diminishes. Since, like most business entities, they are driven to grow profits, often doing so by diversifying, the needs of a specific client are often subordinate to this larger goal. Morgan's aim is to educate corporations engaged in outsourcing so that they choose a firm that focuses on providing one service. This view, however, is somewhat shortsighted, since the long-term trajectory of a company is not always clear and a firm may end up diversifying.
In this regard, there is a curious overlap between the two studies: in some ways both see problems with diversification, Peavy focusing on the liability and Morgan the diminishment in quality of the services rendered. Yet, it is important to note that Peavy focuses on how diversification negatively affects a company providing services to companies outsourcing, whereas Morgan focus on how the latter is negatively impacted.
