If the airspace around centrally located airports were restricted to commercial airliners and only those private planes equipped with radar, most of the private planes traffic would be forced to use outlying airfields .such a reduction in the amount of private-plane traffic would reduce the risk of midair collision around the centrally located airports.
Which of the following, if true, would most strengthen the conclusion drawn in the second sentence?
A. Outlying airfields would be as convenient as centrally located airports for most pilots of private planes.
B. Most outlying airfields are not equipped to handle commercial-airline traffic.
C. Most private planes that use centrally located airports are not equipped with radar.
D. Commercial airliners are at greater risk of becoming involved in midair collisions than are private planes.
E. A reduction in the risk of midair collision would eventually lead to increases in commercial-airline traffic.
审题意：
如果将中心位置的机场附近的空域仅限于商用客机和那些装备了雷达的私人飞机使用，私人飞机流量的绝大部分将被迫使用偏远的机场。这种私人飞机流量的减少将降低在中心位置的机场附近发生空中撞机的危险。

cd的兄弟姐妹们~请帮个忙，这题我会做，问的是如果按照helr老师的分类方法来分类，应该怎么分，等文件做好了之后回馈cd！在此先谢过！

我觉得应该属于因果或者演绎推理，请各路前辈拍砖吧，话说helr老师的方法真好！
