Traveler: Southern Airways has a far worse safety record that 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 ture, 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, ut 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, that 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.

I go for B (if I remember correctly this is a question from GMATPrep): reason: The travel prefers safety, and argues that Southern Airways has a worse safety record than Air Dacentaria. Now you have to find a reason that explains why safety for THIS particular flight shouldn't be worse. B gives you an explanation why Southern Airways usually is less safe but not in this flight

Is B an OA?

I doubt since it says nothing about Air Dacentaria and its usage of this
particular airport.

I prefer E.

I picked E originally but this is why i think E is wrong...

although the proportions of accidents is small, SA may still have a greater accident rate than AD. thus his conclusion still holds, AD is safer.

B weakens it by giving an alternative explanation to why it SA is unsafe. Weakens the premise that SA is unsafe overall; stats are skewed b/c of that one airport.

The argument says that Southern Airways has a far worse safety record that Air Dacentaria
Therefore, although Air Dacentaria is slightly more expensive, I will choose it over Southern Airways for my flight from Pederton to Dacenta.

Since the overall safety is worse for the SA => also on a specific flight the safety is worse.
This is the argument of the text.

The correct answer will destroy this connection somehow: will show that the data is not reliable or that there are distortions, and so on...

B and E...

B. Most Southern Airways flights, ut not its flight from Pederton to Dacenta, use Sarmouth airport, which because of its mountainous location is one of the world's most dangerous.
B says that the overall rate of accidents is overestimated because SA uses a particular airport that is dangerous. So we can infer that, if SA stops using that airport, its safety level would be higher than that of the other company; and because the person will not flight in that airport, the argument is weakened.(This answer shows that the overall data is not a reliable indicator because suffers from the low safety of a single airport).

E. Although the frequency of accidents is greater on Southern Airways, on both airlines the proportion of flights that have accidents is very small.
E does not affect the conclusion. "on both airlines the proportion of flights that have accidents is very small" => when comparing different companies the most important stats are the percentages (not the overall number), and E says that under this point of view there is no difference between the two companies.
