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.
35. Which of the following, if true, would most strengthen the conclusion
drawn in the second sentence?
(D)The number of midair collisions that occur near centrally located
airports has decreased in recent years.
(E) Private planes not equipped with radar systems cause a
disproportionately large number of midair collisions around centrally located
airports.
这题答案是E 但是我第2次看我有可能会选D
第2段的结论是说 因为私人飞机的数量减少 所以会降低空中碰撞的风险
D说空中碰撞的数量降低在最近几年 我觉得也有支持阿
为什麽D错 解答是说 A recent reduction of the number of collisions does not
explain their cause. 我还是看不太懂
有人可以解释一下吗 ORZ
