12. It is clear that none of the volleyball players at yesterday’s office beach party came to work today since everyone who played volleyball at that party got badly sunburned and no one at work today is even slightly sunburned. Which one of the following exhibits a pattern of reasoning that most closely parallels that in the argument above? (A) Since everyone employed by TRF who was given the opportunity to purchase dental insurance did so and everyone who purchased dental insurance saw a dentist, it is clear that no one who failed to see a dentist is employed by TRF. (B) Since no one who was promoted during the past year failed to attend the awards banquet, evidently none of the office managers attended the banquet this year since they were all denied promotion. (C) Since the Donnely report was not finished on time, no one in John’s group could have been assigned to contribute to that report since everyone in John’s group has a reputation for getting assignments in on time. (D) Everyone with an office on the second floor works directly for the president and, as a result, no one with a second floor office will take a July vacation because no one who works for the president will be able to take time off during July. (E) Since all of the people who are now on the MXM Corporation payroll have been employed in the same job for the past five years, it is clear that no one who frequently changes jobs is likely to be hired by MXM.
KEY D
请问C错在哪里？是因为“has a reputation for
getting assignments in on time”这种表述不严谨吗？只是说明可能性比较大？还是确实结构有问题？
C 的缪误：1偷换概念：有准时的好名声不代表没有延误的时候 2.假定没偷换概念：其推理与题干稍差：因为john's-->on time, 所以not on time-->not John's 题干：因为volleyball-->sunburn, work-->no sunburn(i.e. sunburn-->no work) 所以 volleyball-->no work. D:Since 2nd floor-->for president, for president--> no vacation, so 2nd floor--> no vacation. D与题干最接近
