ARGUMENT111- The following appeared in a memo from the vice president of marketing at Dura-Sock, Inc.
"A recent study of Dura-Sock wearers suggests that our company is wasting the money it spends on its patented "Endure" manufacturing process, which ensures that our socks are strong enough to last for two years. Dura-Sock has always advertised its use of the "Endure" process, but the new study shows that the average Dura-Sock customer actually purchases new Dura-Socks every three months. Furthermore, Dura-Sock customers surveyed in our largest market, northeastern United States cities, say that they most value Dura-Sock's stylish appearance and availability in many colors. These findings suggest that Dura-Sock can increase its profits by discontinuing its use of the "Endure" manufacturing process."

The arguer conclude that the Dura-Sock can increase its profits by discontinuing its use of the 'Endure' manufacturing process. The argument relies on the result of a recent study and a survey. Careful examination of this argument reveals some flaws as followed.
Firstly, the result of the recent study is unreliable as nothing about the study is mentioned about how the study was conducted and how the study can represent the general opinions of the consumers. Even if the study is warranted, we only can get the information that the customer would buy new Dura-Socks per three months averagely. It is not informative to conclude that the socks manufactured by 'Endure' process would be through away per three months, maybe the consumers will wear them until totally worn, that is to say, the time Dura-Socks can lasting are important to the consumers.
Secondly, the survey made in northeastern United States cities is unwarranted to support that all the consumers are agree with the participants in this survey. It can not be eliminated that many people do not send back their ideas to whom the 'Endure' is the primary reason to by Dura-Socks. Even if the survey is success in this aspect, its result is still open to doubt. Because residents lived in different areas may have different interests to a same kind of product due to the circumstance they are lived in and the experiences they have ever went through. So that is to say, the residents lived in other districts may have dissimilar ideas about this topic.
Last but not list, the arguer does not provide informative evidences to justify that Dura-Sock can increase its profits by discontinuing 'Endure' in manufacturing process. The profit of a company are depends by a lot of things, such as the market, the economic, the management. The arguer fails to persuade that the company will increase its profits without enough researches about this company and its socks.
