是一道简单的假设题目, 但是我很想有一个正确的思路. 请问你们是如何分析这题的逻辑结构而推出正确答案呢?
36. If the airspace around centrally located airports were restricted to commercial airliners and only those private planes equipped with radar, most of the private-plane traffic would be forced to sue outlying airfields. Such a reduction in the amount of private-plane traffic would reduce the risk of midair collision around the centrally located airports.
The conclusion draw in the first sentence depends on which of the following assumptions?
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. C
答案是C
谢谢
题目说，
装备雷达的私人飞机和商业航线的飞机允许在中心的机场，而大多数的私人飞机被迫去其它地方降落。
这样的调整使得空中的事故降低了
总结一下：有雷达的飞机在中心机场降落，没雷达的一边去，而且这样一来事故少了
可见大多数的私人飞机是没有雷达的。因此都被赶走了，从而降低了事故风险。
因此选C
