The following appeared in a letter from a homeowner to a friend."Of the two leading real estate firms in our town—Adams Realty and Fitch Realty—Adams Realty is clearly superior. Adams has 40 real estate agents; in contrast, Fitch has 25, many of whom work

The argument concludes that Adam Realty is a better real estate firm than Fitch Realty .The author makes few assumptions and supports the conclusion but the assumptions are unsubstantiated.

First, the homeowner states that the in Adams there are 40 real estate agents and in Fitch are 25 of which many are part-time. The assumption is flawed because the author assumes that the number of real estate agents represents the superiority of the firm and he forgets the principle that quantity does not represent quality. So, the more number of employees working at Adams does not make it a better firm than Fitch.

Second, the homeowner further provides evidence by writing about the revenue earned by Adams was twice than Fitch. The revenue earned by the firm does not indicate that the firm is better one. The more revenue earned may be by charging immensely to the clients and if so, then revenue cannot be an indication of Adams performing better than Fitch.

Third, he further persuades by quoting the home sales of Adams averaged $168,000 and Fitch averaged $144,000. The homeowner does not provide details of what criteria were considered while taking the average. Since, no details are described in argument Adams cannot be considered as a superior firm for better price.

Finally, the he makes a comparison of the time taken by both firms at different years. Fitch took 4 months to sell a house 10 years ago and Adams took 1month to sell last year. The analogy to 10 years efficiency of Fitch and past years Adams may not be an ideal one to compare for faster performance of the Firms.

The argument can be further strengthened by providing more evidence about the number of clients in both firms that would answer the assumption of number employees in firms. The price each firms charge for their clients would strengthen the assumption more revenue in Adams and more details of average of the home sales were based. The time each firms took to sell in the same year the same kind of house at same neighborhood would be a better analogy to consider for faster performance. However, the homeowner did not provide supporting evidence to his assumptions and the argument in current state is flawed.
