### HideShow timer Statistics

Since the deregulation of airlines, delays at the nation's increasingly busy airports have increased by 25 percent. To combat this problem, more of the takeoff and landing slots at the busiest airports must be allocated to commercial airlines.

Which of the following, if true, casts the most doubt on the effectiveness of the solution proposed above?

(A) The major causes of delays at the nation's busiest airports are bad weather and overtaxed air traffic control equipment.
(B) Since airline deregulation began, the number of airplanes in operation has increased by 25 percent.
(C) Over 60 percent of the takeoff and landing slots at the nation's busiest airports are reserved for commercial airlines.
(D) After a small midwestern airport doubled its allocation of takeoff and landing slots, the number of delays that were reported decreased by 50 percent.
(E) Since deregulation the average length of delay at the nation's busiest airports has doubled.

Cheers.

This thread is not very popular... Because it is too hard or too obvious?
For me, it was that easy...

SimaQ, could you explain your choice?

A it is.
more allocated takeoff and landing slots to commercial airlines won't help as airports still have overtaxed air traffic control equipment and bad weather.

Firstly I went for C.
If there are delays and more than half of the slots are for commercial flight, then if you add more slots for commercial while closing for non-commercial, it could improve the situation.

A was another option. But the weather is something unforcastable. You cant improve the weather, so you have to choose another way to solve this case. Indeed there are the taxes left.
I dont understand why taxes would impact the delays, maybe there are not enough equipment because they are too expensive.
Finaly, it 's written the major causes. Does that imply that inappropriate attribution of slots CAN'T be a major cause too?

So if I would have to choose, I would first reduce the taxes and then increase the slots for commercial.
But what the hell is the weather doing here?

A is the only choice that weakens the argument and shifts the blame to some other thing from congestion due to deregualtion.

A is the best choice as it tells us the delay are elements beyond the control of the air traffic controller and even increasing takeoff and landing slots will not solve the problem.

The rest of the choices are not good.

(B) supports the solution
(C) does not suggest that 60% is sufficient
(D) bad comparison. the other airport could have its own issues
(E) no relevant data provided here

"A" the best. Tells some other reason.

The argument says that delays at the airport could be reduced if more slots are alocated to commercial airlines...

A) indicates the causes of the delays, which are out of control for any airlines, be it commercial or any other sort....

C) is not because we cannot assume what affects would another 20% or 30% increase in allocation of landing and take off slots to commercial airlines would have...

Only (A) stays within scope. Weather cannot be manipulated in order to improve air traffic control efficiency.

A only tells there are some other reasons which are causing delay on airport.

In C, it is possible that more than 60% are enough. It doesn't refute the argument directly.

overtaxed = overworked
It has nothing to do with taxes

Type - weaken
Boil it down - Allocate more takeoff and landing slots to combat delays
Pre- thinking - What if the delay is not due to too many planes with tight slots i.e some alternate reason has caused the delay
(A) The major causes of delays at the nation's busiest airports are bad weather and overtaxed air traffic control equipment. - Correct

A is the correct answer since the choice provides alternative cause to the reason of the problem.
Since the solution is addressing to the probelem that is no loger there the plan is likely to fail.
