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.

OA: C

I stuck between C and D. Can someone explain? thank u so much![/spoiler]

Boss choice is A ,

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.

(A)Outlying airfields would be as convenient as centrally located airports for most pilots of private planes. In case the private plane driver not compatible , there will more midair in outskirts

D is not an assumption because even though commercial airlines are at greater risk, that does not mean they contribute towards most number of collisions in absolute terms. And even though they did contribute to max collisions the conclusion still talks about reducing the risk of midair collision (even if the reduction is small by the removal of less risky private planes)

If you negate answer option C, it says "most private planes that use centrally located airports are equipped with radar". If that is the case, then these planes would be forced to use outlying airfields and hence the conclusion will fall apart.

Hence, Option C is correct.

You must focus on the claim in the first sentence. In this sentence, the author concern isn't about how much airports are convenient for pilots, instead he or she mostly worries about decreasing the airspace traffic at central airports. You most STRICTLY be loyal with the prompt in this type of questions. Choice 'A' is off topic here. There isn't any clue about airports convenience in the prompt. So eliminate it without doubt.

Hope you find my comment useful.

For 'C' simply ask yourself why if the rule enact, it will decrease many private planes? You probably reach to the choice 'C'.

For 'D', as I replied here on the other comment, this choice is off-topic and off-topic information have not any respect in these questions.

Cheers!
