The following appeared in an article in a health and fitness magazine. Laboratory studies show that Saluda Natural Spring Water contains several of the minerals necessary for good health and that it is completely free of bacteria. Residents of Saluda, the small town where the water is bottled, are hospitalized less frequently than the national average. Even though Saluda Natural Spring Water may seem expensive, drinking it instead of tap water is a wise investment in good health. Discuss how well reasoned... etc.
The argument that drinking Saluda Natural Spring Water instead of tap water is a wise investment in good health is not entirely logically convincing, since it lacks certain supporting factors.
Firstly, the argument assumes that Saluda Natural Spring Water is the major reason why residents of Saluda are less frequently hospitalized than the national average. However, there is little evidence that this water is the only difference between this place and the rest of the country. And the reason why people in other places are more hospitalized are numerous and varied. There are so many other factors that would bring people in other places to hospitals, such as accidents, food contamination, illnesses, etc.
