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
What's the best way to determine the correct answer? Can any experts help?

Conclusion: Number of passengers who refuse to ride Lightning built planes will increase
Premises: There are two manufacturers of light planes in the region. The crash rate of SpeedStar planes has decreased over the last five years.
We're trying to weaken the conclusion, so we want to show that the number of passengers who refuse to ride Lightning built planes will NOT increase. In other words, despite the fact that SpeedStar planes have been crashing less frequently, passengers will not switch from Lightning planes to SpeedStar planes. Why might this be? Well, if SpeedStar is experiencing fewer crashes, but the crashes it does experience are deadlier, that would be a pretty good reason to stick with Lightning planes, as not dying is a fairly high priority for airplane passengers. This is what A conveys.
