Two computer companies, Garnet and Renco, each pay Salcor to provide health insurance for their employees.  Because early treatment of high cholesterol can prevent strokes that would otherwise occur several years later, Salcor encourages Garnet employees to have their cholesterol levels tested and to obtain early treatment for high cholesterol.  Renco employees generally remain with Renco only for a few years, however.  Therefore, Salcor lacks any financial incentive to provide similar encouragement to Renco employees.

Which of the following, if true, most seriously weakens the argument?

A. Early treatment of high cholesterol does not eliminate the possibility of a stroke later in life.

B. People often obtain early treatment for high cholesterol on their own.

C. Garnet hires a significant number of former employees of Renco.

D. Renco and Garnet have approximately the same number of employees.

E. Renco employees are not, on average, significantly younger than Garnet employees.

C

C做是做对了，但是C的意思是
                前员工
                是说互相交流
                他家有
                你家就要有
                这么个意思么

转贴一个很好的解释:那些员工在 Renco 时如果不做胆固醇的检验，进到 Garnet 时，可能就病发中风，Salcor 就要花很多钱去治疗这些员工。所以如果在 Renco 时就已经做检验，那很可能预防中风，那就可以省钱

Which of the following most logically completes the argument below?

Twenty percent of the stores in Morganville's downtown shopping district will fail within five years because they will be competing directly with the SaveMart discount department store newly opened in East Morganville.  The downtown shopping district has lost business at this rate before and has always completely rebounded.  Confidence that it will rebound again from the losses it is now about to suffer is ill founded, however, because _____C_____.
             A    

A. the stores likely to be put out of business by direct competition from SaveMart are the downtown shopping district's anchor stores, on whose ability to draw shoppers many of the other downtown stores depend

B. the bus line that has long connected the downtown area of Morganville with East Morganville has a tradition of carrying shoppers who reside in East Morganville into downtown Morganville to shop

C. when the downtown shopping district has rebounded before, the business premises of a failed business were typically taken over by a business of the same kind as had been there before

D. SaveMart's business plan for the East Morganville store is based on earning low profits, if any, during the first five years of the store's existence

E. it is conceivable that the downtown shopping district could shrink substantially without collapsing altogether

文章题干说此保险公司是同时为R和S两家雇员服务的（Two computer companies, Garnet and Renco, each pay Salcor to provide health insurance for their employees.）

结论说保险公司不推荐R家的员工做test，因为R家的员工做几年就跳槽了（也就是说不值得推荐这些离开R家的员工做test）

C选项说G家雇佣了很多R家的前员工。也就是说这些前员工会变成G家的员工，那么保险公司还对两家公司的员工搞区别对待（只推荐G家的员工做test）就不对了。

结论是：salcor没有finacial incentive
要想seriously weaken,就要找到finacial incentive
如果r雇员都去了g,当然对s来说是好事了，毕竟g也是客户，这就是finacial incentive

是这样啊，说保险公司没有动力给R的员工做早期的检查，因为R的员工做做就走了，但是啊，削弱就说啊，R的员工都去了G啊，因为G也是保险公司的顾客塞，如果员工因为没有在R的时候没有检查出来高胆固醇，然后跳槽去了G，那么保险公司S还是要赔很多的钱啊，所以削弱。

牛掰

恩恩，五楼六楼一家亲，合起来完全解释明白了这个问题~~~~~谢谢

牛掰

哎？ 不对呀？ 选项E为什么不行呢？R的员工平均年龄比G的要大，也就是说虽然没几年R的员工能在公司里，但是他们的发病率要比G高呀~~~~同样也是削弱吧？？？？？为什么E错了呢

peterlongzhang

G和R是两家公司，这两个公司在S保险公司给员工上保险。如果提早做检查，就能减少发病，保险公司就能少赔钱，因此S就劝G让员工赶紧检查。但是因为R的员工带不了几年还没发病就走了，保险公司没有赔钱的风险，因此保险公司S没有经济上的愿望去劝阻R公司搞这个检查。这里有一个假设就是R的员工走了，保险公司就没有赔钱的风险。削弱就是削弱这个。跟年龄大小（说的是过几年容易发病，没说老了容易发病）和员工人数什么的都没关系。
