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 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. The conclusion drawn in the first sentence depends on which of the following assumptions?
选项
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.
答案
C
解析
第一句话得出结论,禁止没有装备雷达的私人飞机使用中心位置的机场将迫使大多数私人飞机不在这些机场起降。除非如选项(C)所说,大多数使用这些机场的私人飞机是没有装备雷达的,否则该结论不能成立。因此第一句话的结论假设了选项(C),(C)是正确答案。该结论不需要假设偏远的机场对私人飞机很方便[选项(A)],因为该项限制使没有装备雷达的飞机别无选择?该结论仅关心对雷达的要求对私人飞机流量有什么样的影响,因此,选项(B),只与商业客机有关和选项(D)和(E),只与空中撞机的危险有关,不一定需要它们为假设。
