The airfares on almost all routes in the country have increased considerably in the past six months. In fact, on some routes, the fares have as much as doubled from what they were six months earlier. Since there has been no significant increase in the number of fliers in the country in the last six months, the media has blamed cartelization in the airline industry for this rapid increase in fares.
Which of the following, if true, undermines the argument above?
(A) The media is known to sensationalize events of public importance to gain more readership/viewership.
(B) The airfares on some routes have actually fallen over the past six months.
(C) Two of the six airline companies operating within the country have shut down operations in the last six months.
(D) The price of aviation fuel increased drastically two years back and has remained at that level since then.
(E) Other neighbouring countries have also seen similar rise in air fares but nobody has accused the airline companies in those countries of cartelization.
Official Explanation
Answer: C
The conclusion is that airfares have gone up and the cause, according to the argument, is cartelization by airline companies. To weaken the argument, we need to provide another explanation for the same effect. C does this by suggesting that the reason for increase in airfares could be the fact that supply of seats in airplanes has gone down.
(A) This is a general statement about the media and doesn’t explain why the airfares have gone up.
(B) This may be true but, in general, the airfares have risen according to the argument.
(C) The correct answer.(D) Since the price of aviation fuel increased two years back, why have the airfares started increasing only in the past six months?
(E) What is true for other neighbouring countries is outside the scope of the argument.
