Official Solution:
The proposal to hire twelve new fraud investigators in Greenvale is foolish. This is because there is sufficient funding to pay the salaries of the new investigators, but not to pay the salaries of additional prosecutors and administrative assistants to process the increased load of fraud cases that new investigators usually generate.
Which of the following, if true, will most seriously weaken the conclusion above?
A. Studies have shown that an increase in the number of a town's fraud investigators does not necessarily reduce fraud.
B. When one neighboring town increased the number of fraud investigators by 20 percent last year, it resulted in 30 percent more charges of fraud and 25 percent more convictions.
C. If funding for the new investigators' salaries is approved, support for other town services will have to be reduced during the next fiscal year.
D. In most United States towns, not all fraud cases result in charges, and not all charges result in trials.
E. Greenvale's ratio of fraud investigators to local officials has reached a level at which an increase in the number of investigators will have a deterrent effect on fraud.
A proposal to hire new fraud investigators is dismissed as foolish because there is not enough funding to cover the salaries of the increased support staff necessary when the number of fraud charges goes up.
The conclusion is based on the premise that hiring new fraud investigators usually increases the number of fraud charges, which in turn increases the need for prosecutors and administrative assistants. Anything that offers evidence that this chain of events may not occur as expected could weaken the argument.
Choice E states that hiring more fraud investigators will result in a "deterrent effect on fraud," meaning that less fraud will occur. This statement properly identifies a point that weakens the conclusion, because increasing the number of investigators will, under this choice,
not necessarily increase the number of cases requiring unaffordable prosecutors and assistants. Choice
E is correct.
Choice A states that studies have shown that the rise in the number of a town's fraud investigators does not necessarily reduce fraud. If fraud is not reduced, then fraud charges will remain the same or possibly go up; this statement does not weaken the conclusion.
Choice B states that when one large town increased the number of its fraud investigators, there were more charges and convictions. The example supports the argument that there will be
more fraud cases, requiring more support staff, and does not weaken the conclusion.
Choice C states that if funding for the new investigators' salaries is granted, funding for other town services will have to be reduced during the next fiscal year. The lack of available funding supports the argument's claim that it will be difficult or impossible to fund salaries of more prosecutors and administrative assistants.
Choice D states that in most United States towns, not all fraud investigations result in charges, and not all charges result in trials. The fact that not all cases lead to charges, or trials, does not undermine the claim made in the argument that more investigators will lead to more fraud cases, which, according to the argument, will need to be processed by additional employees.
