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.

Which of the following, if true, would most strengthen the conclusion drawn in the second sentence?


A. Commercial airliners are already required by law to be equipped with extremely sophisticated radar systems.

B. Centrally located airports are experiencing overcrowded airspace primarily because of sharp increases in commercial-airline traffic.

C. Many pilots of private planes would rather buy radar equipment than be excluded from centrally located airports.

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.

The answer is E.
We can solve this question using the

LOGICAL

approach, since strengthening the conclusion is often a matter of identifying hidden assumptions.

The argument is that reducing the number of private planes without radars will decrease traffic accidents. The clear assumption here is that these types of planes are involved in a large part of accidents. This is exactly what E states.
