Only a reduction of 10 percent in the number of scheduled flights using Greentown’s airport will allow the delays that are so common there to be avoided. Hevelia airstrip, 40 miles away, would, if upgraded and expanded, be an attractive alternative for fully 20 percent of the passengers using Greentown airport. Nevertheless, experts reject the claim that turning Hevelia into a full-service airport would end the chronic delays at Greentown.

　　只有减少G现有飞行计划的10%，才能避免现在G普遍存在的飞机延迟。如果把40英里外的H飞机跑道 进行升级和扩建，那么就会吸引整整20%的坐G的飞机的人。然而，专家却拒绝了这个宣称将H变成以通用飞机场会结束G的飞机习惯性延迟的提案。

　　Which of the following, if true, most helps to justify the experts’ position?

　　以下哪一项，如果成立的话，将可以使得专家的观点成立?

　　(A) Turning Hevelia into a full-service airport would require not only substantial construction at the airport itself, but also the construction of new access highways.

　　将H变成通用机场不仅要求对机场本省进行大量的建设，而且要求修建很多高速公路。

　　(B) A second largely undeveloped airstrip close to Greentown airport would be a more attractive alternative than Hevelia for many passengers who now use Greentown.

　　紧邻G机场的第二大未开发的跑道比G更家的具有吸引力，对G的现有乘客来说。

　　(C) Hevelia airstrip lies in a relatively undeveloped area but would, if it became a full-service airport, be a magnet for commercial and residential development.

　　H跑道位于一个相对未开发的地区，但是如果变成通用机场之后，将会变成一个吸引商业和住户的开发区。

　　(D) If an airplane has to wait to land, the extra jet fuel required adds significantly to the airline’s costs.

　　如果一个飞机正在等待降落的话，多余的燃料极大地增加了机场的花费。

　　(E) Several airlines use Greentown as a regional hub, so that most flights landing at Greentown have many passengers who then take different flights to reach their final destinations.

　　几个航线将G当做一个中继站，所以大部分在G降落的飞机的很多乘客会乘坐不同的飞机去往各自的目的地。
