求解新prep cr1 122

122.   (GWD 30-Q27)

Personnel officer:  The exorbitant cost of our health-insurance benefits reflects the high dollar amount of medical expenses incurred by our employees.  Employees who are out of shape, as a group, have higher doctor bills and longer hospital stays than do their colleagues who are fit.  Therefore, since we must reduce our health-insurance costs, we should offer a rigorous fitness program of jogging and weight lifting to all employees, and require employees who are out of shape to participate.  

The conclusion reached by the personnel officer depends on which of the following assumptions?

A. A person who is fit would receive a routine physical checkup by a doctor less regularly than would a person who is out of shape.

B. The medical expenses incurred by employees who are required to participate in the fitness program would be less than those incurred by employees who are not required to participate.

C. The strenuous activities required of out-of-shape employees by the program would not by themselves generate medical expenses greater than any reduction achieved by the program.

D. The fitness program would serve more employees who are out of shape than it would employees who are fit.

E. The employees who participate in the fitness program would be away from work because of illness less than would the employees who do not participate.
为什么不选B呢？

我是这样想的啊
高额的医疗保险反应了用于员工医疗费用的高昂，一般的，胖的人比体型正常的人需要更高的医疗费用。所以，因为我们必须降低医疗费用，所以可以为胖的人提供塑形计划，并强制要求这部分人参加。
B是说被要求参加瘦身计划的人将会比不被要求的人花费更少的医疗费用。
明显不对啊，因为只有胖的人才被要求，而本身胖的人需要的费用就高于正常体型，参加计划只是能比原来降低点，但并没说低于正常人。

111.      (GWD 30-Q27 different type)

Personnel officer:  The exorbitant cost of our health-insurance benefits reflects the high dollar amount of medical expenses incurred by our employees.  Employees who are out of shape, as a group, have higher doctor bills and longer hospital stays than do their colleagues who are fit.  Therefore, since we must reduce our health-insurance costs, we should offer a rigorous fitness program of jogging and weight lifting to all employees, and require employees who are out of shape to participate.  
Which of the following, if true, provides the most support for the personnel officer's proposal?
A. The medical expenses incurred by fit people who participate in a program of jogging and weight lifting are less than those incurred by fit people who do not participate in such a program.
B. More otherwise fit people are injured by participating in rigorous jogging and weight-lifting programs than are injured by participating in moderate jogging and weight-lifting programs.
C. The likelihood of incurring medical expenses is slightly greater for people who participate in fitness programs offered by their employers than it is for people who participate in programs offered commercially.
D. Moderate fitness programs increase the average person's fitness to the same extent that rigorous fitness programs do.
E. More health problems and injuries are the result of mandatory participation in a fitness program than are the result of voluntary participation.
可是新prep cr1 111的这题同样是用fit people 来支持观点的啊，为什么122这题就不可以呢？

我个人认为，assumption和support问题不太一样。
assumption是作者为了得到结论必须认为是正确的基础，但是可能有多个。122题中C选项如果成立，结论就成立；如果不成立，那么结论就不成立了，所以是一个假设。而B选项我认为说反了，被要求锻炼的人是out-of-shape的人，是保险花费高的人，没被要求的人是fit的，保险花费低的人，所以他们的关系不是“less than”而是“more than”。
support问题中正确答案不需要一定成立，但是成立了会对结论有帮助。A选项说即使是fit的人也是锻炼比不锻炼好，那么就支持了“to all employees”这个方案。自然，即使A选项不成立，假如没有帮助，也不会否定作者的结论。所以A选项不是assumption。

122：降低医疗费用不代表胖人的医疗费用要比正常人低，只要参加运动后比参加前低结论即成立！依理Assumption取非不能完全驳倒结论！
111：support题只要起到加强的作用即可！而且其他选项在support题里全是无关选项。

看清题目问法就行了，若这题问support:这B可以选，因为，一开始说胖子的医疗费比健康人高，B说棒胖子的医疗费将会低于健康人，说明这个措施降低了胖子的医疗费。可以支持。但是可惜的是，assumption是一定要取非的，也就是取否命题，取非后必然weaken才行。这时候B取非就是胖子的医疗费不低于健康人，本来就高于它，现在说不低于它，那我不知道是否相对于以前胖子的医疗费下了？，也就不一定weaken了。这种取非的手法在OG官方解释中 我记得好像就出现1到2处，而官方PP08解释 出现的特别多。它通常的官方说法是，even if 条件取非，结论仍然成立（并非weaken）。所以这是错误答案（这也是GMAC设置选项时惯用伎俩之一）。。。OG当中好像还有一道错误选项的官方话就是：虽然它能support结论，但是even if 条件取非，结论仍然成立。
