1. 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 (a 20 percent reduction) 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, including those used by visitors, throughout our hospital system."

在一次对于抗菌洗手液的实验研究中，UltraClean浓缩液比我们医院现在使用的洗手液多杀灭40%的细菌。在我们Worktown的医院随后所作的对UltraClean的测试中，该医院上报的患者感染数量显著少于(少20%)我们集团的其他医院。因此，为防止严重的患者感染，我们应该在我们的医院系统所有的洗手站提供UltraClean。
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 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(s) can plausibly account for the facts presented in the argument.
3. The following appeared in a health newsletter.
"A ten-year nationwide study of the effectiveness of wearing a helmet while bicycling indicates that ten years ago, approximately 35 percent of all bicyclists reported wearing helmets, whereas today that number is nearly 80 percent. Another study, however, suggests that during the same ten-year period, the number of accidents caused by bicycling has increased 200 percent. These results demonstrate that bicyclists feel safer because they are wearing helmets, and they take more risks as a result. Thus, there is clearly a call for the government to strive to reduce the number of serious injuries from bicycle accidents by launching an education program that concentrates on the factors other than helmet use that are necessary for bicycle safety."
下面这段文字出自一则健康新闻。
一项为期十年的对于在骑自行车时戴头盔的作用的研究显示，10年前所有骑车人中大约有35%的人戴头盔，现在这个比例接近80%。然而另外一项调查显示，在相同的十年期间，因骑车引起的事故数量增加了200%。这些结果说明骑车人因为戴着头盔而感到更安全，因而导致他们面临更大的危险。因此，为减少自行车事故中重伤的数量，政府显然有必要开设自行车行车安全课程，让人们了解除了戴头盔是必须的之外，还有其他需要注意的因素。
Write a response in which you discuss what questions would need to be answered in order to decide whether the recommendation and the argument on which it is based are reasonable. Be sure to explain how the answers to these questions would help to evaluate the recommendation.
