想请教下大家对Argument 62的观点

kanpingUID：3356558

如题，我想了很久都想不到什么有力论点，想请教下大家有什么意见

62. The following appeared in a memo from the director of a large group of hospitals.

"In a laboratory study of liquid antibacterial hand soaps, a concentrated solution of UltraClean produced a 40 percent greater reduction in the bacteria population than did the liquid hand soaps currently used in our hospitals. During a subsequent test of UltraClean at our hospital in Workby, that hospital reported significantly fewer cases of patient infection than did any of the other hospitals in our group. Therefore, to prevent serious patient infections, we should supply UltraClean at all hand-washing stations throughout our hospital system."

Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.

楼主你想到了哪些呢？

首先这类survey,study应用到实践就存在一个条件不同。实验室ultraclean和现实生活中复杂、多变的空气环境很不同。
另外，感染对比涉及不同的医院，医院环境，患者情况什么都不同，此为其一；其二真正能够证明这个玩意儿有用，应该是在一个医院里面设置使用和不使用，这样才有可比性，对不对？
一个小点是刚开始只谈比例，而不知样本总量大小，涉嫌蒙混过关。
等等，还可以有些小毛病可以说

结论给的很草率
