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?
(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 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.
(C) 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.
(D) 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.
(E) Although the frequency of accidents is greater on Southern Airways, on both airlines the proportion of flights that have accidents is very small.
ans: B
題目說: Southern Airways較Air Dacentaria 來的不安全
結論: 要從 Pederton 去 Dacenta， 旅行的人會會選擇Air Dacentaria，因為比較安全，也值得多付點錢for safer flight
問: doubt
這題我B C想了很久，最後選成C
我對B的理解，請各位NN看一下我的想法對嗎?
B: most Southern Airways 用Sarmouth airport 因為他的 mountainous location is one of the world's most dangerous，所以造成Southern Airways 有較多且較嚴重的飛安事故，而從Pederton到 Dacenta並不是使用這個aiport，因而推翻了選擇Southern Airways 會比較不安全之說。
C : smaller capacity=\= safer 所以不選
有時候在做題時，腦袋就會一下子轉不過來，一題搞很久還錯
