Flaw in the Reasoning—CE. The correct answer choice is (E)
Your task in this Method of Reasoning question is to select the answer choice containing the most
accurate description of the flawed argument in the stimulus. The argument proceeds:
Premise: our club recruited the best volleyball players in the city
Sub-Conclusion: thus, we will have the best team in the city
Premise: the best team in the city will be the team most likely to win the city
Conclusion: so, our club will almost certainly be city champions this year
Your prephrase is that the argument contains two flaws. First, the subsidiary conclusion results from
an error of composition, inferring that the team as a whole will share a characteristic, being the best,
held by its individual team members. Next, the conclusion that the teams will almost certainly be city
champions improperly results from a relativity flaw. It is inappropriate to infer from the comparative
premise, that the team is the most likely of the teams to win, the non-comparative conclusion that the
team almost certainly will win. The correct answer choice will describe this flawed argumentation.
The incorrect answers will not describe these flaws. Instead they will describe argumentation that
did not occur in the stimulus, or they will accurately describe a portion of the argument that is not
Answer choice (A): The argument did not presume the team, an entity, would be best solely on
the basis of competition. Rather, it stated the team will be best because the club recruited the best
volleyball players in the city.
Answer choice (B): The conclusion that the team would be successful, i.e., win the city
championship, resulted from the claim that the team will be the best in the city. While the argument
was flawed in other ways, the talent of the team is not irrelevant to the success of the team.
Answer choice (C): The argument predicted the outcome of the championship based on the premise
that the best team will be the team most likely to win the championship, and was not based solely on
a comparison between the parties in the competition.
Answer choice (D): This choice describes an error of division, the reverse of the error of composition
reasoning flaw that lead to the sub-conclusion.
Answer choice (E): This is the correct answer choice.While the stimulus contained two reasoning
flaws, the test makers chose to describe only one of them in this answer choice, the relativity flaw,
in which the argument inferred from the team being the one most likely to win that it would almost
