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.'
提纲
1 EZ collects trash twice a week, while ABC collects only once.但是Ez的价格要比ABC高,如果Walnut Grove town只需要每周一次,那就没有必要选择Ez每周两次的服务
2 EZ—which, like ABC, currently has a fleet of 20 trucks—has ordered additional trucks。一方面并不知道ABC有没有增加车辆,也不知道两个公司本来的车辆大小,另一方面EZ增加车辆可能是由于原有车辆数不能满足客户的需要才增加车辆,而ABC的车辆数能够保证其完成任务。
3 调查的可靠性,调查主题,反映情况等
In this analysis, the author attempts to convince us that EZ is a better choose other than ABC as trash collection services for Walnut. But this notion is specious on several grounds.
First of all, although it is the fact that EZ correct trash more often than ABC, the author provide no evidence that Walnut demand the service twice week instead of once. If the trash in Welnut is not so much to be collected twice a week, there is no need to choose EZ which charge $500 more than ABC.
Secondly, the author claims that EZ currently has trucks as much as ABC, while the former has ordered additional trucks. Since this is the case, it would not guarantee that EZ provide better service for Whalnut than ABC. Only by comparing the number of truck will not prove anything. It is possible that the trucks of ABC have more capacity than that of EZ. Another possibility is that 20 trucks is enough for ABC to run its business but is still in lack for EZ. Besides, when will the ordered car of EZ come into use still remains a question.
Thirdly, the author provide no assurance that the survey on which the argument depends is statically reliable. Lacking the information about the number of person surveyed and the number of respondents, it is impossible to assess the validity of the results. For example, if 100 persons were surveyed but only 5 responded, the conclusion that the performance of EZ is satisfied would be highly suspected. Besides, even this is the fact, it is still possible that the performance of ABC is more satisfied than that of EZ, since there is no information about ABC.
In conclusion, the analysis is not well-supported. To bolster it, the author should provide more evidence that it is necessary for Walnut to ask for trash collection twice a week and more trucks means better service for Walnut. In addition, to strengthen the analysis the author should provide more information about the survey and conduct the survey not only concerning the performance of EZ but ABC as well. |
