Since the introduction of low-cost airlines, delays at the nation's

Question

Since the introduction of low-cost airlines, delays at the nation's busiest airports have increased by 50 percent. To combat this problem, takeoff and landing slots at the busiest airports must be re-allocated with a significant preference towards traditional airlines, or those not considered low-cost airlines, over low-cost airlines.

If true, each of the following casts doubt on the effectiveness of the solution proposed above EXCEPT

A. The primary cause of delays at the nation's busiest airports is weather-related.

B. The delays caused by traditional airlines have continually increased, while those caused by low-cost airlines have continually decreased since the introduction of low-cost airlines.

C. Low-cost airlines account for a higher proportion of the delays than do non-low-cost airlines.

D Traditional airlines already account for approximately ninety percent of all takeoff and landing slots at the nation's busiest airports, as low-cost airlines tend to fly into and out of less busy airports.

E. Low-cost airlines, on average, account for a much lower proportion of the delays than do non-low-cost airlines.

What level of Question is this

exuberantvivek · Answer

Correct answer is C.

If low-cost airlines account for a higher proportion of the delays than do non-low-cost airlines, then giving more slots to traditional airline will reduce the delay.

"Except" type question, basically all of them should weaken the argument except one, which should strengthen the argument and that will be the correct choice.

A. The primary cause of delays at the nation's busiest airports is weather-related.
Clear weakener. Eliminate.

B. The delays caused by traditional airlines have continually increased, while those caused by low-cost airlines have continually decreased since the introduction of low-cost airlines.
Again, this weakens the argument. Eliminate

C. Low-cost airlines account for a higher proportion of the delays than do non-low-cost airlines. 
Yes. This one strengthens the argument hence its the one.

D Traditional airlines already account for approximately ninety percent of all takeoff and landing slots at the nation's busiest airports, as low-cost airlines tend to fly into and out of less busy airports.
Weakener.

E. Low-cost airlines, on average, account for a much lower proportion of the delays than do non-low-cost airlines.
Doesnt matter, also doesn't strengthen.

Official Explanation

The correct answer to this question is (C). This is a unique type of WEAKEN question, requiring the test taker to identify the one answer choice that does not provide information that refutes the conclusion that allocating more takeoff and landing slots to traditional airlines will decrease airport delays.  Choices A, B, D,  and  E  are incorrect as they provide information that refutes or weakens the conclusion.

Choice C  is the correct answer choice, which does not weaken, but in fact strengthens the conclusion. That low-cost airlines account for a higher proportion of delays than do traditional airlines suggests that reserving more spots for the traditional airlines would help to reduce the overall number of delays.
