TOPIC: ARGUMENT17 - The following appeared in a letter to the editor of the Walnut Grove town newspaper.
"Walnut Grove's town council has advocated switching from EZ Disposal (which has had the contract for trash collection services in Walnut Grove for the past ten years) to ABC Waste, because EZ recently raised its monthly fee from $2,000 to $2,500 a month, whereas ABC's fee is still $2,000. But the town council is mistaken; we should continue using EZ. EZ collects trash twice a week, while ABC collects only once. Moreover, EZ-which, like ABC, currently has a fleet of 20 trucks-has ordered additional trucks. Finally, EZ provides exceptional service: 80 percent of respondents to last year's town survey agreed that they were 'satisfied' with EZ's performance."

In this argument, the author concludes that the advocating that Walnut Grove (WG) should switch from EZ Disposal to ABC Waste is mistaken. To support his opinion, he points out that EZ collects trash twice a week, while ABC collects only once. In addition, he presents that EZ currently has ordered additional trucks. Moreover, he also claims that EZ provides exceptional service. However, there exist several intermediate steps that one should take before jumping to the conclusion.
To begin with, the author shows that concerning the times of collecting trash, the number of EZ is as twice as that of ABC. So we should go on the contract with EZ. However, it is not necessarily the case. The number of collecting trash is not sufficient to demonstrate the high quality of any company. Because we do not know how much the trash is and whether we need the service or not. Perhaps, the trash in WG town is so limited that once a week is apt enough. Besides, more trucks do not certainly mean the improved productivity of EZ. The author fails to rule out other alternatives involving in the condition, such as although they bought more trucks, EZ is not intending to use them to supply collecting service. Or they will replace some of the original trucks with the new ones so that the whole number of the trucks in EZ is the same as that of ABC Company. Even if more trucks are indeed devoted in the collecting trash, it is still possible that ABC manages their service more efficiently with fewer trucks.
Furthermore, although the fee of EZ is $2500, while that of ABC is merely $2000, we cannot conclude which one is better before we consider the costs and awards of both companies. It is possible that higher fee does not provide better service as the author expects. So before the argument supplies more solid information on the correlation between the price and the service, I cannot make sweeping conclusion.
Moreover, the survey lacks of objective information demonstrating that it is not self-report. (The respondents answer the questions under some hints or according to certain expectations.) In addition, we should get the information on the specific number, background of the sample. And the author should guarantee the randomness of the selecting the sample. Even if all of these elements are considered and meet, an only one-year period is not long time frame for citizens to believe. Thus we must lengthen the time of the survey in order to render more valid outcomes.
Overall, at the first glance, the argument appears to be somehow plausible, however, further reflection reveals several important logical flaws. Before I make my final decision, the arguer must present more substantial information on the specific conditions of EZ and ABC, such as the cost and benefit, tax, transportation, selling, the quality of the employees and the individual services. Additionally, the argument also is supposed to reflect the realistic feedback of the residents of WG town by an objective survey and a statistical report. Otherwise, I can hardly be persuaded by the invalid and hasty conclusion as it stands.
