OG13 CR22题 有没有好心人给我解释一下这道题啊？感激不尽！！
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.

Which of the following ,if true,most helps to justify the experts' position?
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.
B.A second largely undeveloped airstrip close to Greentownairport would be a more attractive alternative than Hevelia for many passengers who now use Greentown.
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.
D.If an airplane has to wait to land,the extra jet fuel required adds significantly to the airline's costs.
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.

减少10%的flight不会导致delay
建H 将有20%的乘客不去现在的G机场，而该去H机场，
但是，专家认为把H变成机场并不会结束G的delay

选E
A 与delay无关
B 比较选项，原文说的是H，这里再说另一个机场之类，无关
C 与commercial 发展有毛关系
D与cost无关
E因为不管加不加H，有些乘客都无法离开G机场，所以还有很多乘客，delay无法结束
