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:
(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.

这题的题干读不大懂The data have been adjusted to allow for differences in the ages of patients.这里的data到底有没有排除年龄的因素？？
当时费费上课的时候笔记上记的是：
allow for ：扣去：把由年龄而造成的过高的死亡率的差异扣除。
到底应该怎么解释？

“数据考虑病人的年龄差别（的影响）后进行了调整。”。当然这是一个很好的提示，让我们关注选项中有关病人年龄的选项。但是我觉得此题的关键是不同医院的评比标准的比较，一定是说不同医院之间怎么了。C只是说了病人的情况，并没有在不同医院之间进行比较，所以谈不到差异问题，所以无关。
