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.

    The director argues that UltraClean should be supplied at all hand`washing stations throughout he hospital system to prevent serious patient infections. Close scrutiny of the argument and the evidences on which it bases, I find some assumptions of the argument need to be addressed.

    ts1
    First of all, UltraClean would significantly decrease the patient infections in other hospitals is based on the assumption that the whole situation in other hospitals are the same as that of Workby hospital.基于假设：所有医院的医生处理病人的方式、治疗原则、手术方法都是一样，护士的护理也一样，所有医院各个科室的环境卫生、规章制度、家属及外来人员来访规定也一样。但现实可能并非如此。

    ts2
    Seconds, the director bases the argument upon the assumption that the conditions of patients in Workby hospital, during the subsequent test, are not more benign than others in else hospitals, and clinical works in Workby hospital do not pay special attention to prevent infection during that time. 可能的是，workday当时的病人病情更轻些，因此也不容易感染，而且，毕竟是在检测期，所以医生在手术时会更加注意无菌原则，并尽量将手术做得更好，对病人用药也更加细心，护士对病人的护理也更加细致、贴心，同时更加严格控制家属及外来人员的来访，限时限量。

    ts3
    Finally, the director relies on the assumption that the laboratory conditions for UltraClean and the currently used soaps are the same, then come to the conclusion that the former is more effective in killing bacteria population. UltraClean是在实验室检测的，那儿的环境及卫生标准肯定更高更好，细菌一般也不容易繁殖，而现在所用的香皂，检测地点不清楚，也许其是在医院里面检测的，那儿的卫生肯定没实验室的好，其结果就不再那么有说服力了。
