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 drawn in the first sentence depends on which of the following assumptions?

正确答案: C

请问OG36是什么意思?

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.

不好意思,不太明白36题是什么意思?请指教一下

假设:OG中比较典型的一道.

前提:装RADAR的私人飞机可以使用commercial airliners.

结论:多数私人飞机不能使用.

问必要条件:是前提和结论之间的必要桥梁.

则选C.....

取非C,削弱,则为正确答案.

对于这道题目我是这么理解的

前提 If the airspace around centrally located airports were restricted to commercial airliners and only those private planes equipped with radar

结论 most of the private-plane traffic would be forced to sue outlying airfields

所以假设 就是 Most private planes that use centrally located airports are not equipped with radar.
