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."
the letter to the editor of the Walnut Grove town disprove the town council`s decision that switching the trash collection services to ABC Disposal. To justify his statement, the arguer points out that even the EZ has raised its monthly fee it collects trash twice a week, while ABC collects only once. Moreover, the EZ will currently order more trucks. In addition, 80 percent of respondents of last year`s town survey satisfied the EZ`s performance. The argument sound reasonable at the first glimpse. However, my further reflect reveal that it suffers from at least three logical fallacies as follows.
Firstly, the threshold problem of the argument is that the arguer unfairly asserts that the EZ Company is better for the reason that it collect one more time a week. It is equally possible that the EZ Company`s services are not efficient, so that they need one more time to have their job done, may be the ABC Company can well complete their job with just one collection.
Another problem that weakens the logical of the argument is that the arguer claim that the EZ Company is better, because EZ Company _which, like ABC, currently has a fleet of 20 truck-has ordered additional trucks. However, the author failed to indicate what how the extra trucks be used for. Perhaps the additional trucks will be employed to collect trash in other town. Without precluding this possibility, I remain unconvinced that the additional truck will be used for the services in Walnut Grove.
Finally, the arguer has cite the last year`s survey that 80 percent of the respondents satisfied with EZ`s performance. Yet, the author provides too little information about the survey. Whether the survey cover the overall population in the town, whether the subjects are chosen randomly, whether the survey was carried on by a objective institution or by the EZ Company itself. Any of the possibilities above will undermine the validity of the survey. Moreover, even the survey was strictly controlled survey can only reflect the situation of last year, may be this year the services of EZ are not satisfied. In addition, the survey failed to make a comparison between EZ Company and ABC Company. The service in ABC Company may be satisfied by 90 percent of respondents or more.
In sum, the arguer fail to substantiate his claim that the trash collection services of EZ Disposal is better than that in the ABC Company, because the evident cited and the logical inference do not lead to strong support to what the arguer maintains. To make the argument more convincing, the author needs to provide more information on EZ Company`s services is really better than the ABC Company , the additional truck will be used for the service in Walnut Grove, and that the service of EZ Company is satisfied by more people than the ABC Company. Therefore, if the argument had included the factors discussed above, it would have been more thorough and acceptable. |
