Question ID:PT44 S4 Q20 Passage:Advertisement:  Each of the Economic Merit Prize winners from the past 25 years is covered by the Acme retirement plan. Since the winners of the nation's most prestigious award for economists have thus clearly recognized that the Acme plan offers them a financially secure future, it is probably a good plan for anyone with retirement needs similar to theirs. Stem:The advertisement's argumentation is most vulnerable to criticism on which one of the following grounds? Correct Answer Choice:DChoice A:It ignores the possibility that the majority of Economic Merit Prize winners from previous years used a retirement plan other than the Acme plan. Choice B:It fails to address adequately the possibility that any of several retirement plans would be good enough for, and offer a financially secure future to, Economic Merit Prize winners. Choice C:It appeals to the fact that supposed experts have endorsed the argument's main conclusion, rather than appealing to direct evidence for that conclusion. Choice D:It takes for granted that some winners of the Economic Merit Prize have deliberately selected the Acme retirement plan, rather than having had it chosen for them by their employers. Choice E:It presumes, without providing justification, that each of the Economic Merit Prize winners has retirement plan needs that are identical to the advertisement's intended audience's retirement plan needs.
