Parallel Reasoning—SN, PR. The correct answer choice is (D)
The stimulus features a principle containing conditional reasoning, which is identifiable by the use of the necessary condition indicator “unless.” After applying the Unless Equation, the principle can be diagrammed as follows:
- 1st Term Serves = First-term board member serves on finance committee
Acct. = Accountant
Support = Support by all board members
1st Term Serves or
+ 1st Term Serves
Answer choice (A): This answer choice is incorrect, because Simkins need only satisfy one of the two necessary conditions in order to serve on the committee. Just because he does not meet one of the conditions (being an accountant), that is not enough to prevent him from serving: we also need to know if his membership is supported by all the members of the board.
Answer choice (B): This answer choice can be easily eliminated, because the principle specifically applies to first-term board members, and Timmons is a third-term member. Additionally, the principle cannot be used to determine when someone should be on the finance committee; we can only determine when someone should not be on it.
Answer choice (C): If Ruiz was a first-term member when he joined the finance committee, it would be reasonable to conclude that he must have been supported by all the board members. However, since we do not know whether Ruiz was a first-term member, it is unclear whether the principle applies to his case.
Answer choice (D): This is the correct answer choice. We know that Klein is a first-term board member, so he must meet at least one of the two necessary conditions in order to serve on the finance committee. He is not an accountant, however, so his appointment must be supported by all members of the board. Thus, if any board member opposes his appointment, it is reasonable to conclude that Klein should not be allowed on the committee:
+ 1st Term Serves
Answer choice (E): If Mabry were a first-term member, then indeed the conclusion would be properly drawn. As with answer choice (C), however, we have no knowledge about whether Mabry is a first-term board member. Absent that information, we can draw no conclusions regarding his eligibility to join the finance committee.
