17. Lists of hospitals have been compiled showing which hospitals have patient death rates exceeding the national average. The data have been adjusted to allow for differences in the ages of patients.

Each of the following, if true, provides a good logical ground for hospitals to object to interpreting rank on these lists as one of the indices of the quality of hospital care EXCEPT:

(A) Rank order might indicate insignificant differences, rather than large differences, in numbers of patient deaths.

(B) Hospitals that keep patients longer are likely to have higher death rates than those that discharge patients earlier but do not record deaths of patients at home after discharge.

(C) Patients who are very old on admission to a hospital are less likely than younger patients to survive the same types of illnesses or surgical procedures.

(D) Some hospitals serve a larger proportion of low-income patients, who tend to be more seriously ill when admitted to a hospital.

(E) For-profit hospitals sometimes do not provide intensive-care units and other expensive services for very sick patients but refer or transfer such patients to other hospitals.

这个题A是啥意思啊？？怎么排除A ？

排名，就病人死亡率而言，可能代表没有意义的差别，而不是（医院间Rate）很大的差别。答案是C吗？因为原文提及“The data have been adjusted to allow for differences in the ages of patients”

答案是C没问题，

但关于A ，我还有一点模糊。

文章说要建立一个关于DEATH RATE的排名，问题说，要根据这个DEATH RATE来建立一个RANK ，这个RANK体现了医院的医治水平。

A 选项说，这个RANK可能只能在死亡人数（而非死亡率）方面 体现出无关的差距，而非大的差距。

这个A应该是个无关的选项啊，它怎么可能也做为医院OGJECTION的理由呢？？？

这个排名只能体现出死亡人数这个不重要方面的差距而体现不出来别的差距.

死亡人数不是衡量一个医院好坏的重要指标.

这题我也有点晕，C错在什么地方？如果一个医院接收的都是老人，另外的医院接收的都是年轻的？这个死亡率不是也不能体现医院的医治水平吗？

17. Lists of hospitals have been compiled showing which hospitals have patient death rates exceeding the national average. The data have been adjusted to allow for differences in the ages of patients.

这句话该怎么理解呢？

.(C) Patients who are very old on admission to a hospital are less likely than younger patients to survive the same types of illnesses or surgical procedures.

题目是说年轻人和年老的人的区别没有提到医院接收病人的年龄问题。
