17The 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."
提纲:
1 作者假设ABC不能提供满意的服务,而没有给出原因,信誉,工作态度等,仅仅是说ABC每周清理一次垃圾,也许一次清理对于城市已经足够;
2 EZ增加20辆卡车不一定就用来装运垃圾,其他用途,为其他城市服务;
3 调查不具有代表性;
The arguer claims that even though the EZ Disposal has raised its monthly fee from $2,000 to $2,500 every month, the town should still use EZ rather than the ABC Waste whose fee is still $2,000 each month. To support the decision, the arguer illustrates that EZ collects trash twice a week, but ABC collects only once. Further more, EZ has ordered other 20 trucks for its work. And in addition, the arguer cites a survey to convince the readers. After some careful examination of the argument, we will find several flaws in the argument.
In the first place, the arguer makes an assumption that ABC can not provide good service as EZ, but there is not any evidence to confirm the assumption. Because we do not know the reputation of the ABC, or maybe the service which supplied by ABC is more convenient than EZ. The arguer only informs us that EZ collects trash twice a week, while ABC collects only once, but this can not demonstrate the conclusion. Maybe we do not have so many trashes to collect, only once a week is enough, then there is no meaning of more collecting work. While even though all above is the case, the arguer fails to consider that the city has employed the EZ for ten years, maybe we do not know the sufficient service about ABC, which causes the ignorance of ABC. Considering the possibilities above, the decision is not persuasive as it stands.
Secondly, the arguer points out that EZ has ordered a fleet of 20 trucks additional. But the arguer fails to give us any information about the additional trucks’ utility. Maybe those trucks are not used for collecting trash, or EZ maybe expand its service to other cities, which has no relationship with Walnut Grove, then the additional trucks can not be the reason for our choice.
Thirdly, the survey arguer cited is not persuasive as it illustrates. The arguer tells us that 80 percent of respondents to last year's town survey agreed that they were 'satisfied' with EZ's performance. But we do not know the survey population and the conditions of respondents. Maybe the survey is conducted among only a few people, and those who respond the survey are just those who really satisfied with EZ’s performance, but how about other people who fail to respond to the survey? Maybe the most non-respondents are unsatisfied with EZ, then the survey can not represent all residents in the city, so the conclusion is untenable.
To sum up, the argument is not convincing as the arguer aclaims. To make it more persuasive, the arguer should exclude all the possible reasons for a better choice of ABC. In addition, we should inform more information about the additional 20 trucks EZ has ordered. At last, the arguer should provide us more sufficient statistic about the survey.
