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.

OA：C
不明白为啥选C。再一次失去逻辑思考能力。。

我觉得是题没看懂，我举个对比例子你做做看

小明数学考90分，小刚数学考70分。小明数学水平比小刚高。
我反对以上论证由于以下原因EXCEPT:
A.       数学考试不能代表数学水平高低。
B.       数学成绩低的同学是由于做对难题而浪费了大量的时间，进而没做完其它简单题；而只有能否做对难题才能代表数学水平高低。
C.       大学数学比小学数学难考高分。
D.       小明考的是小学数学，小刚考的是大学数学。
E.       小明看见大学数学难考，不敢考，就去考小学数学去了。而小刚考得是大学数学。

回到本题，提干说的是weaken EXCEPT
结论：医院的death rate的rank应该被视为医院好坏的衡量标准。
其它选项都能weaken结论，就是统计样本的选取问题
比如说柯南的破案率只有20%，你能说柯南破案水平低吗？不能，因为他接手的都是难案子。
C选项说的是一个日常生活中的常识，但对于一个医院好坏的衡量有gap，就是你仍然不知道这些医院是收young patients还是very old patients

(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.

明白鸟，谢谢！

不得不说你的例子太好了。通俗易懂。看完这个简单的例子马上明白上面那个难的例子了。

其实我做到C时也很怀疑它，但就因为它说得太像正确答案了，就变成怀疑自己了。
