Personnel officer:  The exorbitant cost of our health-insurance benefitsreflects the high dollar amount of medical expenses incurred by ouremployees.  Employees who are out ofshape, as a group, have higher doctor bills and longer hospital stays than dotheir colleagues who are fit.  Therefore,since we must reduce our health-insurance costs, we should offer a rigorousfitness program of jogging and weight lifting to all employees, and requireemployees who are out of shape to participate.
The conclusion reached by thepersonnel officer depends on which of the following assumptions?
A. A person who is fit wouldreceive a routine physical checkup by a doctor less regularly than would aperson who is out of shape.
B. The medical expenses incurred byemployees who are required to participate in the fitness program would be lessthan those incurred by employees who are not required to participate.
C. The strenuous activitiesrequired of out-of-shape employees by the program would not by themselvesgenerate medical expenses greater than any reduction achieved by the program.
D. The fitness program would servemore employees who are out of shape than it would employees who are fit.
E. The employees who participate inthe fitness program would be away from work because of illness less than wouldthe employees who do not participate.
答案选C
看了很多帖子，我还是对B选项有疑问，参加的比不参加的花费少，原来都不参加的，现在有一部分参加了，总花费不就减少了吗？
取反的话，就是参加的比不参加的花费多，正好也削弱了嘛，就是原来都不参加的，现在有一部分参加了，反而总花费会增加，不会减少。
我的问题到底出在哪里？
求指导，谢谢~~

这道题我开始也选的B，因为之前做过一道很相似的题目，但是比较之后发现其实是不同的：

答案：C

另一题：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.
答案：A

我自己的总结如下：以上两道题的对比可以看出Assumption和support题的区别：因为FIT的人可能参加，可能不参加，所以他们参加后医疗费用可能减少只能作为MUST REDUCED THE COST的support.而作为assumption，必须考虑到所有可能增加cost的因素，排除掉使它会增加的因素，即第一题的C.
而第一题B选项中参加的人比不参加的人的费用可能会少，首先可能不是肯定；第二：参加的人比不参加的人少，可是参加的人不一定比他没参加之前少~，它和第二题A选项的不同在于,第二题A选项中比较的是同一类人fit，即默认是同一个人，他们参加后的费用会减少，则cost自然会减少.当然其实这个选项也不严密，因为很可能所有fit的人的费用并不相同，参加后的fit人的费用虽然比不参加的fit的人要少，但很可能比他以前的要多，但是第二题显然其他选项要么削弱，要么无关，这个选项最好。

仅自己的思考，open to discuss~~~

我觉得是无关比较，看计划是否有效，要看out of shape的人锻炼前后费用是否下降，也就是同一个人在锻炼前锻炼后的变化。对于fit的人也是一样，跟自己比较才能看出效果
我们对B取非The medical expenses incurred by employees whoare required to participate in the fitness program would not be less than thoseincurred by employees who are not required to participate. 即使那些被要求参加的人的费用没有比不要求参加的人多，但是只要他们比他们自己参加前的费用有降低了，那还是说明这个方案成功了。
举个例子，锻炼前的费用   out of shape 100    fit 80  总费用180
                 锻炼后的费用    out of shape 90     fit 80   总费用 170
我们可以看到费用还是下降的，所以即使B取非，也不能对文章的argument进行削弱。所以B不是assumption~
