570. Only a reduction of 10 percent in the number of scheduled flightsusing Greentown’s airport will allow the delays that are so common there to beavoided. Hevelia airstrip, 40 miles away, would, if upgraded and expanded, bean attractive alternative for fully 20 percent of the passengers usingGreentown airport. Nevertheless, experts reject the claim that turning Heveliainto a full-service airport would end the chronic delays at Greentown. Which of the following, if true, most helpsto justify the experts’ position? [A]TurningHevelia into a full-service airport would require not only substantialconstruction at the airport itself, but also the construction of new accesshighways. [B]A second largely undeveloped airstrip close to Greentown airportwould be a more attractive alternative than Hevelia for many passengers who nowuse Greentown. [C]Hevelia airstrip lies in a relatively undeveloped area but would, ifit became a full-service airport, be a magnet for commercial and residentialdevelopment. [D]If an airplane has to wait to land, the extra jet fuel required addssignificantly to the airline's costs. [E]Several airlines use Greentown as a regional hub, so that mostflights landing at Greentown have many passengers who then take differentflights to reach their final destinations.
请问专家拒绝的把H机场变成full-service airport的提案有没有被评估过呀?我总觉得前面只是介绍了H机场的基本状况,这个应该不算是评估吧?那是不是就可以用方案的有效性来削弱了? 但是用因果的逻辑好像也说得过去,,,感觉把自己绕进去了,求解答啦~
