Traveler: Southern Airways has a far worse safety record than Air Dacentaria over the past few years, in terms of both the frequency of accidents and the severity of accidents. Therefore, although Air Dacentaria is slightly more expensive, I will choose it over Southern Airways for my flight from Pederton to Dacenta, since it is worth paying extra to have a safer flight.
Which of the following, if true, casts the most serious doubt on the traveler's argument?
Air Dacentaria's flight from Pederton to Dacenta is nonstop, whereas Southern Airways' flight touches down in Gorinda on the way.
Most Southern Airways flights, but not its flight from Pederton to Dacenta, use Sarmouth airport, which because of its mountainous location is one of the world's most dangerous.
For its flights from Pederton to Dacenta, Southern Airways uses a different model of airplane, with a smaller capacity, than the model Air Dacentaria uses for its flights on the same route.
Only in the last few years has the cost of flying from Pederton to Dacenta been more expensive on Air Dacentaria than on Southern Airways
Although the frequency of accidents is greater on Southern Airways, on both airlines the proportion of flights that have accidents is very small.
长难句训练:Most Southern Airways flights, but not its flight from Pederton to Dacenta, use Sarmouth airport, which because of its mountainous location is one of the world's most dangerous.
its指代单数,那不能指代南航的flights,它是复数;its mountainous location 说明指的是机场而不是航线从P到D,所以its只能指代Sarmouth airport。
大部分南航航线都要使用Sarmouth airport,那是全世界最危险的机场-->南航事故率高并不是因为驾驶技术不好二是因为Sarmouth airport的关系;现在P到D的航线不用这个机场了,自然是安全的航线,用不着多花钱坐D家的飞机。
D,只在过去的几年里,从P到D的航班才D家的比南航的贵,意思是再远几年,两家的票价是一样的;同时也不能说明D的更贵的票价没有被用到增加航班安全上。属于无关选项。
