　　1. 首先，医生的人数与质量之间没有必然的因果原因。profit跟质量也无关系。很可能treating price is significantly lower。

　　2. 成功率不能说明问题。缺乏其他的证据，忽略了他因：比如因为质量高，所以很多serious illness的，而送往其他医院的一般都是common cases.

　　In this argument the author concludes that university hospitals provide no better care than private or community hospitals. The author bases this conclusion on the following claims about university hospitals: the ones in this region employ 15 percent fewer doctors; they have a 20 percent lower success rate in treating patients; they pay their staffs less money; they make less profit than community hospitals; and they utilize doctors who divide their time between teaching, research and treating patients. This argument is unconvincing for several reasons.

　　The most egregious reasoning error in the argument is the authors use of evidence pertaining to university hospitals in this region as the basis for a generalization about all university hospitals. The underlying assumption operative in this inference is that university hospitals in this region are representative of all university hospitals. No evidence is offered to support this gratuitous assumption.
