ARGUMENT217 - The following appeared in a brochure promoting the purchase of local franchises for a national chain of gyms.
"Now is the time to invest in a Power-Lift Gym franchise so that you can profit from opening one of our gyms in your town. Consider the current trends: Power-Lift Gyms are already popular among customers in 500 locations, and national surveys indicate increasing concern with weight loss and physical fitness. Furthermore, last year's sales of books and magazines on personal health totaled more than $50 million, and purchases of home exercise equipment almost doubled. Investing now in a Power-Lift Gym franchise will guarantee a quick profit."
The author of this brochure recommends that people invest in Power-Lift Gym for a guaranteed profit. To support his recommendation, the author cites a national survey indicating the recent popularity in health care and body building. To further support his claim, the author provides evidence of current increasing sales in health books and home exercise equipments. However, close scrutiny of its evidences reveals several logical flaws in the argument.
First of all, the author’s claim of increasing popularity in Power-Lift Gym rests on the evidence that Power-Lift Gym is favorable in 500 locations and that a national survey indicates the increasing concerning in health care and bogy building. However, we are not informed that the preference(performance)
in these 500 locations could represent the choices of people nationwide. It is possible that people in this 500 area indeed have a favor in sports and have a financial ability to consume in gym. Meanwhile, the author provides no evidence that the national survey could stand for the area where people would like to open a Power-Lift Gym. Moreover, concerns on weight loss and physical fitness could not reveal the people's preferences in sporting at gyms since there are other plausible ways for people to exercise, such as jogging in a park, bicycling around mountains and dancing at a square. If any statement above is the case, the author's claim seems unconvincing.
Secondly, the author bases his claim on the assumption that last year's increasing sales in health magazines and home exercise equipments have illustrated the increasing interests in gyms among people. Yet, the author provides no evidence that this books mainly concerns with sporting at gyms. On the contrary, people's choices to buy home exercise equipments reveal their preference in exercising at home, rather than at a public gym. Without ruling out these possibilities, any conclusion based on this evidence is unfair.
Thirdly, the author has made a hasty conclusion that investing in Power-Lift Gym would definitely earn a profit. Even if people nationwide have a desire to exercise at a gym, they perhaps could not afford it. Thus, people consuming in the gym could possibly numbered. What’ more, profits in a company could be influenced by many other factors, such as rents, management costs inflation and the like. In guaranteeing the quick profit the author fails to consider these plausible factors.
In sum, the argument is not well supported. To persuade me the author should provide more clear evidence that people in this country indeed prefer to exercise in a gym and the Power-Lift Gym is inexpensive for average people to engage in. To better evaluate the argument, the author should provide a market analysis to ensure the guaranteed profit after investing in Power-Lift Gym.
