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

答案的解释不是很清楚，求大神指点一下。。。

答案是C么？如果不是就糗大了~
premise是1. 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 2.Renco employees generally remain with Renco only for a few years
注意 保险公司的目标还是盈利 它提供这个服务是想通过先花点小钱把潜在的大钱的威胁给灭了

结论是Salcor lacks any financial incentive to provide similar encouragement to Renco employees.

之所以这么推理是因为R公司的雇员反正工作不了几年，等不到得中风的那天

要weaken它的话有一种方法就是指出其实这个premise是不能support这个conclusion的

C选项表明了 无论最后的帐还是要算到S公司头上的~so 保险公司还是乖乖给R公司提供保险吧

是C，你这样说来我倒有点懂了，不过好像和答案上的解释不太一样
