gre改革后新版gre写作新题库里的作文方面的一个重要变化是有了指导语。而指导语的作用是有助于我们的逻辑性写作，以下是新版gre写作新题库内有关argument122的写作部分：
题目：
The following appeared in a memo from the director of a large group of hospitals.
In a controlled laboratory study of liquid hand soaps, a concentrated solution of extra strength UltraClean hand soap produced a 40 percent greater reduction in harmful bacteria than did the liquid hand soaps currently used in our hospitals. During our recent test of regular-strength UltraClean with doctors, nurses, and visitors at our hospital in Worktown, the hospital reported significantly fewer cases of patient infection than did any of the other hospitals in our group. The explanation for the 20 percent reduction in patient infections is the use of UltraClean soap.
Write a response in which you discuss one or more alternative explanations that could rival the proposed explanation and explain how your explanation can plausibly account for the facts presented in the argument.
中文翻译：
再一次对于抗菌洗手液的实验研究中，超强UC浓缩液比我们医院目前使用的洗手液多杀40%的有害细菌。我们对在W的医院的使用常规UC洗手液的医生，护士以及访客做的随后测试中发现，该医院上报的患者感染数量明显少于我们集团的其他医院。很明显这减少的20%的患者是由于使用了UC洗手液。
写一篇回应，在其中讨论一个或数个可以和文中的解释相竞争的他种解释，并说明你提出的解释是如何可信的解释和说明文中呈现的事实的。
