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 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 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.
题干If the airspace around centrally located airports were restricted to commercial airliners and only those private planes equipped with radar这句话的理解,到底是指装有雷达装置的私人飞机不能使用centrally located airport,还是没有雷达装置的私人飞机不能使用呢? |
