17.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."
Walnut Grove的市委提议选择ABC Waste,而不是EZ Disposal(它是过去十年中和Walnut
Grove签约提供垃圾收集服务的机构),因为EZ最近把他们每月的收费从$2000提高到了$2500,而ABC仍然是$2000。但市委是错误的,我们应该继续使用EZ。EZ每周收集两次垃圾,而ABC只收集一次。而且,EZ当前的卡车拥有量和ABC一样都是20辆,但它已定购了更多的车辆。最后,EZ还提供优越的服务:去年市镇调查中80%的回应者同意他们对于EZ的表现是"满意"的。
提纲:一 E一周两次不代表服务质量好
二 E最近新添了卡车,不一定会提供更好的服务
三 调查的可信度
The recommendation endorsed in this argument is that the WZ waste should still be elected to serve the town of Walnut Grove for trash collection. The basis for this recommendation is that although the EZ recently raised its monthly fee, it will offer the better service by the frequency of the trash collection and its additional order of trucks. An additional reason given in support of this recommendation is that the EZ`s performance in the last year`s town survey is satisfied with the citizen. While this augment has some merit, there are a few assumptions that deserve attention.
Firstly, the author fails to reveal that twice a week of trash collection is representative of a good service without any sufficient providence. Perhaps the time of the collection is so short that can not assure all the trash will be collected, on the other hand, the one time collection of ABC may be long enough to collect the whole week`s trash. Or perhaps the time of the EZ`s collection is not suited to of the citizen`s daily life the schedule that there were not one at home when they collected the trash. In short, without more convincing evidence of the comparative quality of the collection between the WZ and ABC, the author cannot convince me that the service of EZ will be superior than ABC.
In the second part, even if admitted that more trucks may enhance the quality of gathering service, the fact that EZ ordered additional trucks fails to support the assumption that the EZ will serve better than ABC. It is entirely possible that the EZ do not pay for the trucks for the lack of money by the accidental affair. Or perhaps, that the additional trucks will be used to do other things, which has nothing to do with supporting the better service, rather than to collect garbage. Thus, lacking reliable evidences of the utilization of the trucks, it is difficult to accept that EZ`s serves is better.
In the third part, the speaker provides no assurance that the last year`s survey considered the satisfactory of the EZ`s service is statically reliable. Perhaps that people inclined to EZ were more willing to respond to the survey than other people or perhaps the survey`s sample may not be sufficient in size. Lacking evidence that the survey is reliable, the author cannot reasonably rely on the survey in recommending that the Walnut Grove town should choose the EZ.
To sum up, the author has not succeeded in providing compelling reasons for choosing EZ as a trash collection. To strengthen the conclusion, the speaker must provide additional evidence about the effectiveness of EZ`s work and the reliability of the survey to better evaluate the argument. |
