Weaken—#%. The correct answer choice is (D)
Your task in this Weaken question is to select the answer that most undermines the conclusion that
airlines are overconcerned about the comfort of passengers flying on business. Reordered for clarity,
the argument proceeds:
Premise: several airlines are increasing elbow room and leg room in business class due
to surveys that show business travelers value additional space more than better
Premise: but, leisure travelers purchase 80 percent of all airline tickets
Conclusion: thus, airlines are overconcerned about the comforts of business travelers, and
should instead focus on the comfort of leisure passengers
The most obvious weakness in this argument is that the conclusion relies on a single premise
presenting a large percentage, and appears to presume that a large percentage requires a large
concomitant number. So, your prephrase is that the correct answer will undermine the conclusion by
showing that despite the percentage of tickets purchased by leisure travelers, the business travelers
provide a greater percentage of the revenue.
The incorrect answers will not undermine the conclusion, and instead will either have no effect on
the conclusion or will support it.
Answer choice (A): Without information suggesting the airlines should be more concerned with the
satisfaction of business travelers than leisure travelers, this answer has no effect on the conclusion.
Answer choice (B): You may be attracted to this answer choice because it implies the airlines can
improve the comfort of both passenger groups at the same time. However, this compromise position
does not undermine the conclusion that the airlines are overconcerned with the comforts of business
Answer choice (C): This choice does not affect the conclusion, because it merely states something
concerning which leisure travelers are not primarily concerned, and fails to address the conclusion.
Answer choice (D): This is the correct answer choice.This choice is correct because it provides
that despite the greater percentage of tickets sold to leisure travelers, business travelers provide a far
greater proportion of the airlines’ revenue.
Answer choice (E): This choice does not affect the conclusion, because you do not have sufficient
context to gauge the affect of this tendency by leisure travelers to buy only discounted tickets. For
example, how does this tendency affect the airlines’ revenue, specifically the difference in revenue
provided by business travelers versus leisure travelers?
