再问gwd－3－8

Q8:

Which of the following most logically completes the passage?

Garnet and RenCo each provide health care for their employees.  Garnet pays for both testing of its employees’ cholesterol levels and treatment of high cholesterol.  This policy saves Garnet money, since high cholesterol left untreated for many years leads to conditions that require very expensive treatment.  However, RenCo dose not have the same financial incentive to adopt such a policy, because ______.

A.     early treatment of high cholesterol dose not entirely eliminate the possibility of a stroke later in life

B.     the mass media regularly feature stories encouraging people to maintain diets that are low in cholesterol

C.     RenCo has significantly more employees than Garnet has

D.     RenCo’s employees are unlikely to have higher cholesterol levels than Garnet’s employees

E.      the average length of time an employee stays with RenCo is less than it is with Garnet

E说雇员工作的平均年限在rc比在gn的短，文章说如果那个病拖久了治起来就要花很多钱，可是E并没说平均年限短到什么程度呀，是不是短到了可以不花钱提前治疗的程度呢？比如gn平均年限20年rc19年，而那个病拖15年就很严重了，那么rc还是要支付治病费用的，因此它还是有理由（financial incentive ）采取提前治疗的策略的。

大家看呢

1。用排除法可知E为答案。易混的是D。D错在胆固醇水平高点低点的影响如何，原文没信息，故D错。剩下E为答案。

2。在单位呆的时间长短对公司是否采用该法有影响，所以E对，虽然没讲界限，但对问题没影响，因为说出原因不需要充分性。请注意DE的区别。一个胆固醇高点低点有何影响原文没信息，一个时间长点短点有影响。

那请问A为什么不对？

This policy saves Garnet money, since high cholesterol left untreated for many years leads to conditions that require very expensive treatment.

这个意思是，公司只为在职员工支付一定的治疗费用是吗？

我怎么没这个意识呢。

怎么能判断有关和无关哪？

LAWYER说“胆固醇水平高点低点的影响如何，原文没信息”，可 “在单位呆的时间长短”文中也没提呀。怎样的推断才是没有添加自己的信息？我始终对逻辑没能入门。

谢谢！

谢谢PAOPAO和LAWYER。

This policy saves Garnet money, since high cholesterol left untreated for many years leads to conditions that require very expensive treatment.

当时就是后半句没看懂，怎么推出save money 来了。能解释一下吗？
