Traveler:Southern Airways has a far worst safty record than Air Dacentaria over the past few years, in terms of both the frequency of accidents and the severity of accidents. Therefore, althought 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 ?
A)Air Dacentaria's flight from Pederton to Dacenta is nonstop,whereas Southern Airways' flight touches down in Gorinda on the way.
B)Most Southern Airways flight, but not its flight from Pederton to Dacenta,use Sarmouth airport, which because of its mountains location is one of the world's most dangerous.
答案為B
結論:因為AD 失事率低,雖然貴但仍會搭乘SA
但我不明瞭為何?我選A

請幫幫忙 感謝
