If the airspace around centrally located airport were restricted to commercial airlines and only those private 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?
(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 airlines 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 increase in commercial airline traffic.
Can someone please detail about the Conclusion of the Argument.
The question stem says that the conclusion in the first sentence. If we analyze the structure of the sentence, then we will see that the stimulus contains two opinions
i) most of the private-plane traffic would be forced to use outlying airfields.
ii) Such a reduction in the amount of private-plane traffic would reduce the risk of midair collision around the centrally located airports.
The overall structure goes like this: First part of the fist sentence is the premise for i) and i) is used as a premise for the main conclusion ii).
i) is the intermediate conclusion, which the questions stem talks about.
We have to find an assumption that the author has to make to make his claim valid. Our assumption should validate that "most of the private-plane traffic would be forced to use outlying airfields"
First sentence says "only those
private equipped with radar", so, the commercial planes not equipped with radar would not be able to use the airspace around the centrally located airport. Now, if most planes do not have a radar then they will be forced to use outlaying fields, reducing the overall traffic. Answer choice (C) does is very well, others could be true, but not necessarily validate the conclusion.
Hope that helps,
