Discuss how well reasoned you find this argument.

　　1.The following appeared in a memorandum¹ written by the vice² 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 Painesville, which has many such residents. Painesville 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 aerobics³ classes are always full. We can even anticipate a new generation of customers: Painesville's schoolchildren are required to participate in a 'fitness for life' program, which emphasizes the benefits of regular exercise at an early age."
 
　　2.The following appeared in a letter sent by a committee of homeowners from the Deer haven⁴ Acres to all homeowners in Deer haven Acres.

　　"Seven years ago, homeowners in nearby Brookville community adopted a set of restrictions⁵ on how the community's yards should be landscaped and what colors the exteriors⁶ of homes should be painted. Since then, average property values have tripled in Brookville. In order to raise property values in Deer haven Acres, we should adopt our own set of restrictions on landscaping and house painting."

　　3.The following appeared in a newspaper article about law firms in the city of Megalopolis⁷.

　　"In Megalopolis, the number of law school graduates who went to work for large, corporate⁸ firms declined by 15% over the last three years, whereas an increasing number of graduates took jobs at small, general practice firms. Even though large firms usually offer much higher salaries, law school graduates are choosing to work for the smaller firms most likely because they experience greater job satisfaction at smaller firms. In a survey of first-year students at a leading law school, most agreed with the statement that earning a high salary was less important to them than job satisfaction. This finding suggests that the large, corporate firms of Megalopolis will need to offer graduates more benefits and incentives⁹ and reduce the number of hours they must work."
 
　　4."Of the two leading real estate firms in our town---Adams Realty and Fitch Realty---Adams is clearly superior. Adams has 40 real estate agents. In contrast, Fitch has 25, many of whom work only part-time. Moreover, Adams' revenue last year was twice as high as that of Fitch, and included home sales that averaged $168,000, compared to Fitch's $144,000. Homes listed with Adams sell faster as well: ten years ago, I listed my home with Fitch and it took more than four months to sell; last year, when I sold another home, I listed it with Adams, and it took only one month. Thus, if you want to sell your home quickly and at a good price, you should use Adams."
