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 letter, the author recommends the Walnut Grove's (WG's) town council to continue using EZ Disposal. To support his standpoint, the author lists such evidences: 1, EZ collects trash twice a week, two times more than ABC Disposal. 2,EZ has ordered twenty additional trucks. 3, A last year's survey shows that 80 percent of respondents agreed that they were 'satisfied' with EZ. The author commits some fallacies.
Firstly, there is no evidence to prove the priority of the EZ's method that collects trash twice a week. Suppose WG locates in a cold area, and trash disposal is not so crucial so that collecting once a week demonstrates little difference from twice a week. As a result, taking into account the raise of the fee, the council would certainly advocate switching from EZ to ABC.
Secondly, the proof that EZ has added a fleet of 20 trucks makes no sense to convince us of choosing EZ. On one hand, the usage of these additional trucks is not provided in this letter. It is possible that these trucks are used as transportations for cargos. And even these trucks are used for trash collect; there is no proof to assure WG's town council the improvement in the efficiency of trash collection.
Thirdly, there are some questions to the survey. The author must figure out how many civilians take part in the survey, the proportion of the respondents to these refusing to answer the survey, and the identification of these respondents. Lacking these important figures, the survey is not sufficient. Even though the survey is enough, the attitude of these respondents to ABC is needed for comparison. Maybe they satisfied with ABC much more than EZ.
In conclusion, the author fails to provide us with enough proof. In order to make the recommendation more convincible, he should first indicate the exact information of the survey and then show the priority of the methods implemented by EZ. |
