Question Stats:

77% (01:24) correct 22% (01:29) wrong based on 35 sessions
The facts show that the fear of flying in airplanes is not rational. In 1986 alone, there were 46,000 fatalities in highway accidents, but from 1980 to the present an average of only 77 per year in accidents on major domestic airlines. The rate for regional airlines was only sligh tly higher.

If the evidence cited above is accurate, which of the following would be most important to know in order to evaluate the force of that evidence?

(A) Whether repeated airplane travel allays fear of flying in airplanes
(B) Whether regional and domestic airlines spend the same average amount of time per aircraft on maintenance
(C) How many people reported a fear of flying in airplanes that was strong enough to prevent them from traveling by air
(D) How many people per year have traveled by highway and how many by air since 1980
(E) How much higher the accident rate has been for regional airlines than for major domestic airlines since 1980

If the evidence cited above is accurate, which of the following would be most important to know in order to evaluate the force of that evidence?

In addressing Logical Reasoning style Reading Comprehension problems, first identify the question task. In this case, the task is to find the choice that "would be most important to know in order to evaluate the evidence".

Then, identify the conclusion. In this case, that "the facts show that the fear of flying in airplanes is not rational". So, the correct choice should allow the reader to better determine if the fear of flying is or is not rational.

Evaluate the choices looking to eliminate choices that have a vague impact, or no impact on the conclusion.

(A) Whether repeated airplane travel allays fear of flying in airplanes
What allays fear has no clear impact on the conclusion, so eliminate for having no impact.

(B) Whether regional and domestic airlines spend the same average amount of time per aircraft on maintenance
What regional and domestic airlines spend on maintenance has no clear impact on the conclusion, so eliminate for having no impact.

(C) How many people reported a fear of flying in airplanes that was strong enough to prevent them from traveling by air
How strong the fear of flying is has no clear impact on the conclusion, so eliminate for having no impact.

(D) How many people per year have traveled by highway and how many by air since 1980
The number of people traveling by highway and by air could skew the collision rates, so select as having a potential impact in need of further evaluation.

(E) How much higher the accident rate has been for regional airlines than for major domestic airlines since 1980
What the difference is in the accident rate for regional and domestic airlines has no clear impact on the conclusion, so eliminate for having no impact.

Choice D is the only choice that provides additional evidence to help evaluate the conclusion, so select Choice D.
