题目：
The following appeared in a memorandum written by the vice president of Nature's Way, a chain of stores selling health food and other health-related products.
'Previous experience has shown that our stores are most profitable in areas where residents are highly concerned with leading healthy lives. We should therefore build our next new store in Plainsville, which has many such residents. Plainsville merchants report that sales of running shoes and exercise clothing are at all-time highs. The local health club, which nearly closed five years ago due to lack of business, has more members than ever, and the weight training and aerobics classes are always full. We can even anticipate a new generation of customers: Plainsville's schoolchildren are required to participate in a 'fitness for life' program, which emphasizes the benefits of regular exercise at an early age.'
正文：
In this argument, the speaker concludes that we should build our next new store in Plainsville, which has many residents who are highly concerned with leading healthy lives. To support this argument ,the speaker cites the Plainsville merchants report that sales of running shoes and exercise clothing are at all-time highs. In addition, the author also points out that the local health club, which nearly closed five years ago due to lack of business, has more members than ever, and the weight training and aerobics classes are always full. However, this argument depends on a series of doubtful evidences, which render it unconvincing as it stands.

To begin with, the speaker makes a conclusion from the Plainsville merchants report that residents in Plainsville love sports and lead healthy lives. But the speaker provides no evidence that this is the case. Moreover, perhaps residents in Plainsville do sports just for entertainment and release themselves from jobs which trap them all days. Or perhaps, people living in Plainsville is accustomed to the running shoes and exercise clothing which is soft and convenient to move. Either scenario will explain why sales of running shoes and exercise clothing are at all-time highs that is not caused by the concern with healthy lives of residents in Plainsville.  

Secondly, the authors assumes that residents in Plainsville are concerned with leading healthy lives for the reason that the weight training and aerobics classes in the local health club are always full. In relies on the lack of the evidence such as the health conditions of members in classes, the speaker overlooks the possibility that club members who leaded a unhealthy life, for instance, overweight, have to join in the classes to lose weight or take aerobics movement. Without ruling out this reasonably alternative explanation for the purpose of club members, the author cannot justified that people living in Plainsville lead healthy lives.

Finally, the argument relies on the assumption that we can anticipate Plainsville's schoolchildren as a new generation of customers because students are required to participate in a 'fitness for life' program, yet the speaker has not provided any evidence to substantiate this conclusion. It is possible that Plainsville's schoolchildren only have to do some regular exercises in the program so that large amount of requirement for the healthy food and other health-related product will not exist in Plainsville. The evidence lead little credible support to the speaker’s conclusion that we can anticipate students in Plainsville as a new group of cuctomers.

All in all, this argument is ill conceived and poorly supported. To strengthen it, the speaker should rule out that members in weight training and aerobics classes have to solve the health problem such as overweight. To better evaluate the argument, we need more informations about when and where people wear running shoes and exercise clothing. In addition, we need know whether Plainsville's schoolchildren require large amount of sport-related products.
