The claim that schools and companies can prevent lower absenteeism by making sure students' and employees' daily use of a nutritional supplement derived from fish oil seems somewhat reasonable at first glance. After all, the arguer does offer some relevant evidence, and the assumptions weakening this argument are not without any merit. However, several important concerns which he/she fails to take into account may undermine the argument seriously.
In the first place, lacking more specific information about the life styles of people living near East Meria (EM), it is impossible to make any informed conclusion. Although people there consume many fish and seldom go for the doctor, there is no obvious and convincing causal relationship between fish consumption and health. The arguer ignores some other factors--such as fresh air, clean and unpolluted water, harmonious neighborhood, and average income-- that may be important in determining the health of people.
In the second place, the arguer unfairly assumes that less cold means lower absenteeism. Admittedly, cold is the reason most frequently given for absences form school and work compared with heart disease, stroke, maternity leave, and so on. Common sense tells us that cold is also often used as a perfect excuse for short leaves result from laziness or some personal affairs. Consequently, even daily use of lchthaid can really lead to less cold, most people will find other proper excuses for their absenteeism.
What further weakens the argument is without knowing the effect of Ichthaid, we cannot accept the author's conclusion. Granted taking more fish can really ensure less cold, without any product guarantee we cannot make a presumptuous judgment that this kind of supplement will have similar effect. The arguer just gives us a false analogy.
As it stands, this argument suffers from three critical flaws. To strengthen it, the arguer would have to demonstrate that high fish consumption results to better health and less cold. Furthermore, he/she must provide enough and acceptable evidence to rule out all the above-mentioned possibilities that might undermine the argument.
