题目： 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?

题目： 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?

题目： 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?

题目： 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?

题目： Technology Analyst: The programmers at the website Cyberepicuria have recently made a breakthrough, solving a hard programming problem. They finally have perfected a special program in which users can enter any foods or any flavors they like, and the website will suggest different foods and food combinations with somewhat different flavors that the users will also like. The website will charge users a modest fee for access. Users of the beta version ecstatically have reported that, because of the program's suggestions, they have discovered whole new categories of food that they absolutely love. No other website offers anything like this. Because Cyberepicuria is the only website offering this service, anyone who invests in Cyberepicuria right now is likely to double or triple their money in a very short time. Which of the following, if true, most seriously weakens the analyst's argument above?
