题目:ARGUMENT38 - The following memo appeared in the newsletter of the West Meria Public Health Council.
"An innovative treatment has come to our attention that promises to significantly reduce absenteeism in our schools and workplaces. A study reports that in nearby East Meria, where fish consumption is very high, people visit the doctor only once or twice per year for the treatment of colds. Clearly, eating a substantial amount of fish can prevent colds. Since colds are the reason most frequently given for absences from school and work, we recommend the daily use of Ichthaid, a nutritional supplement derived from fish oil, as a good way to prevent colds and lower absenteeism."

In this newsletter, the arguer claims that the people in West Meria (WM) should daily use Ichthaid, a nutritional supplement derived from fish oil, in order to prevent colds and lower absenteeism. To strengthen the conclusion, the arguer points out that a study shows that in nearby East Meria (EM), where fish consumption is very high, the people merely get cold. In addition, the arguer assumes that the colds are the most frequently reason for absences from school and work. However, the perspective, be it seemingly reasonable at the first glance, suffers from several critical flaws.
To begin with, the result of the study lacks of credibility. First, the statistics were based only on data from some people living in EM, however, it is entirely possible that those people are not representative of all the citizen in EM, let alone WM. In addition, since the arguer does not provide any details of the people involved in the survey, we know nothing about their ages, genders, current health conditions, eating habits, living patterns -- all of which serve to the reliability of the survey. It is entirely possible that the people living in EM often build their bodies and take good care of themselves, so they can hardly get the disease, such as cold. Moreover, the arguer ignores the possibility that maybe the people do not always go to the hospital even if they catch colds, and that the huge consumption of the fish maybe export to other places rather than eating by the citizens in EM. Without considering the comprehensive sample data source and eliminating these possible scenarios, the arguer cannot simply rely on these statistics to support the claims that eating a substantial amount of fish can prevent colds.
What is more, the arguer fails to establish the causal relationship between colds and absences from school and work. It is unfair to assume that the former is responsible for the later. As a matter of fact, cold is not a good indication of absences, which might result from some other factors, such as fever, laziness, emergency, even the earthquake. For example, if somebody went to the bar late in the night with his friends and got drunk deeply, it is very likely that he will not go to work next morning and using cold as an alibi to the boss in order to avoid the penalty, such as docking. In short, without ruling out such possibilities, the arguer's conclusion remains dubious at best.
Last but not the least, the arguer assumes that the proposed measure -- eating Ichthaid daily -- is both necessary and sufficient for prevent colds and reduce absenteeism, yet the arguer does not provide any evidence to solidify either assumption. Perhaps the arguer can also achieve the objective by other means -- for instance, using the punishment, such as more homework to the students who often absent from school, or reducing the salary for the workers who often absent from work. Even if eating the fish oil is necessary to meet the arguer's goal, it is entirely possible that this action by itself would not suffice -- due to the possibilities that the people will still get other diseases or encounter emergencies such as an accident for their parents or children, so they cannot go to school or work even if then do not get colds. All in all, lacking such evidence, I cannot be swayed by the arguer's poorly developed conclusion.
To sum up, this argument is neither sound nor persuasive as it stands. Not only does it ignores certain significant concerns, but also cites in the analysis with the evidence and study, which fails to lend strong support to what the arguer claims. To make the argument more convincing, the arguer must present more facts that colds is the most frequent reason for absences from school and work. To bolster the argument, the arguer would have to produce more specific evidence concerning the background of the people who participate in the survey. If the argument includes the given factors discussed above, it would have been more thorough and adequate.
