My answer for this question is D, however I can't find the OA for this question. Please help me with this
(D) is the only possible answer.
(A) Whether repeated airplane travel allays fear of flying in airplanesInformation on whether fear of flying is allayed does not help with determining whether it makes sense to believe that flying is dangerous.
(B) Whether regional and domestic airlines spend the same average amount of time per aircraft on maintenanceRegardless of whether they spend the same average amount of time, the statistics still support the conclusion.
(C) How many people reported a fear of flying in airplanes that was strong enough to prevent them from traveling by airThis information does not help us to determine whether fear of flying is rational.
(D) How many people per year have traveled by highway and how many by air since 1980This information could help us to evaluate the argument.
We have only the absolute number of fatalities per year associated with each type of travel. To determine whether flying is truly safer than traveling by highway, we need to know the percentage of travelers who died in accidents, not just the absolute number. Information on how many people have traveled in each way allows us to calculate those percentages.
(E) How much higher the accident rate has been for regional airlines than for major domesticairlines since 1980This information would not help us to determine whether flying is safe, only to compare the safety of the two types of airlines.
The correct answer is (D).
