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
Greentown airport 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 commercialand
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.


答案E,我选了B

1，OA说对B说：This statement indicates that the undeveloped airstrip near Greentown might be a better wayto
alleviate flight delays at Greentown,but it tells us nothing about the effects that converting the
Hevelia airstrip to a full-service airport would have were it to be carried out.
选项说了有比B更好，但没说把H convert之后的结果。但是文章已经说了convert之后移过去20%的人原来机场就不delay了，为什么选项还要再说。。

2，OA对E说：E Correct. This statement provides support for the experts' position because it gives a reason for
thinking that the number of scheduled flights at Greentown would not be reduced, even if Hevelia
airstrip became an attractive alternative for some 20 percent of Greentown's passengers.

原文说 so that most flights landing at Green town have many passengers who then take differentflights to reach their final destinations.
我觉得这里有个many，就是说该转机的让他在老机场转，many以外不转机的让他到H去坐飞机，不是正好分流，避免delay么。。又不是所有乘客都是转机。。

求解！谢谢

PS，那如果B不对，什么样的题才应该选除他因的选项啊？？

感觉楼主想我以前一样陷入了思维误区。。。原文要的答案是“加强某

措施不行”，B是说“另外一个方法也行”，必须无关呀。。。我以前也总

是误选这样的选项。。。

个人感觉不能一味地关注“他因”，关注conclusion才是重点。

PS：我记得一般都是“他因削弱”的嘛。。。

个人见解勿喷

题干的逻辑链是：10%减少班机可以avoid delay H扩建后可以分流20%的乘客 BUT experts ：不可行
B选项out of scope
E选项 Green的飞机most是要转机的 所以H扩建后分流了乘客 却不能分流班机 解释了experts' opinion

同意楼上的！这里是一个陷阱啦~
注意原文说的是：
.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.
一个是the number of scheduled flights，后面则是the passengers，是gmat在偷换概念。所以我们读题一定要认真，一不小心就掉进出题老头们挖的陷阱了
