There are two main manufacturers of light plains in this regional market: SpeedStar and Lightning. Unlike the crash rate of lightning built airplanes, the crash rate of speed star airplanes has decreased in the last five years. Thus, although the number of passengers who refuse to take lightning built airplanes has not yet increased, it will inevitably increase.

Which of the following, if true, most seriously weakens the argument above..?

1. the rate of crashes of speedstar airplanes that involve fatalities and injuries has increased in the last five years.
2.lightning built airplanes make up the majority of the fleets of low-cost airlines, which charge travelers approx. 25 % less per trip than do airlines that use SpeedStar
3.the price that airline pay for the lightning built airplane has remained constant in the past five years
4. changes in airline consumer preference always lag behind subtle trends in airline safety rates
5. The Federal Aviation Association has begun an investigation into safety practices at SpeedStar's manufacturing plant
[Reveal] Spoiler: OA

There are two main manufacturers of light plains in this regional market: SpeedStar and Lightning. Unlike the crash rate of lightning built airplanes, the crash rate of speed star airplanes has decreased in the last five years. Thus, although the number of passengers who refuse to take lightning built airplanes has not yet increased, it will inevitably increase.
IMO A
Since the rates of crashes of Speedstar aeroplanes causing fatalities and injuries have increased over the years future passengers may not prefer to travel by Speedstar.This is inspite of the fact that crash rate of Speed star aeroplanes has dereased over five years. This option provides the most convincing reason as to why travelers should not opt to travel by Speed star aeroplanes.All other options do not weaken the argument as much. So A is the answer. Please give me kudos . I need them badly to increase my score.

Why is option B incorrect?


Hello csaluja -

If you read the argument, it talks more about the safety of the airplane and not the cost. Considering this as a premise of the argument cost does not beat the safety of the passengers, thus, cost does not provide a strong reason for passengers to choose the airplane.

Hope this help.

two main manufacturers SpeedStar and Lightning.
the crash rate of speed star airplanes has decreased in the last five years.
Thus the number will inevitably increase.
why author thinks that number will increase because crash rate of speed star airplanes has decreased
what if crash caused many fatalities then number will not increase
A is the answer

I believe the OA has many holes:-
the crash rate of SS plane has decreased while the crash rate of lightning remained same or increased:- what conclusion we make from this? Crash rate of SS is higher? lower ? or equal to Crash rate of lightening=>>> nothing because we dont know the actual crash rate of both manufacturer.
So just because the crash rate of SS decreased and Crash rate of lightening increased does not necessarily make passenger choose one over the other.

Since there can be scenario like this:-
Crash Rate of SS Before 50% after 30%
Crash Rate of lightening before 1% after 1.5%

Would request experts to explain.
