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.（D）

(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.

i just want to ask why can not i choose A?THANX

It is clear that none of the volleyball players (Anetagive)at yesterday’s office beach party came to work today (C) since everyone who played volleyball at that party (A) got badly sunburned (B)and no one at work today (Cnegative)is even slightly sunburned (B).

I label the relations using A, B, and C. Conclusion is the first sentence. According to the question, A→B, C(negative)→B, therefore, A (negative)→C

(A) Since everyone employed by TRF (A) who was given the opportunity to purchase dental insurance (B) did so and everyone who purchased dental insurance (B) saw a dentist (C), it is clear that no one who failed to see a dentist (C negative) is employed by TRF (A).

So the relationship is A→B, B→C, then C(negative)→A, obviously different from the above. You can certainly try it out with D, it works perfect.

1。该题很容易排除A,C,E。原文的推理为everyone.....no one....----->none of。有这种推理结构的只有D，B

2。对于B，no one是指promoted 。和结论没有任何重复。而原文的no one是指at work today ，即结论的动作。故和原文不相似。

明白明白！
