题目
Augument17 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."
翻译: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
(1)市委应该确认是否需要每周收集2次
(2)应确认收集Walnut Grove是否需要20辆卡车或者更多,如果需要,EZ增加的卡车是否用来收集
Walnut Grove的垃圾
(3)80%的回答者说满意,可是没有说调查了多少人,调查的人是否代表大多数人的意见,而且那是去年的调查,有可能现在的满意度已经变了。

正文(417字)
In this argument, the arguer recommends that the suggestion of Walnut Grove's town council that switching from EZ Disposal to ABC Waste is wrong because although EZ raised its monthly fee from $2000 to $2500, they collects trash twice a week, and they has ordered additional trucks, moreover, according to last year's town survey, 80% of the respondents were satisfied with EZ. The reasoning seems logical, but after a careful examination, we can find several fatal flaws as follows.
Firstly, the arguer should make sure whether the town's trash need to be collected twice a week. It's possible that the town does not have lots of trash that need collection twice a week, then the service of collection twice a week is a waste, and collection once a week is enough.
Secondly, although EZ has ordered additional trucks, we are not sure if it need. So the arguer should survey how many trucks were used by EZ to collect Walnut Grove's trash. If the number is less than 20, then adding trucks is not necessary. If the trucks are still not enough after 20 trucks are all used, then adding trucks is necessary. Grant that adding trucks is necessary, the arguer should affirm whether the new added trucks are used to serve Walnut Grove's trash collection.
Thirdly, the survey's result is also doubtable. It only reveals 80% of respondents were satisfied, but does not indicates how many people took the survey and if they can represent most people's opinion. For example, if the town has 500 residents, but only 20 people took the survey, and 15 people responded, then only 12 people said they are satisfied. Thus, the survey is invalid. In addition, the survey was conducted last year, and one year past, the percent of satisfaction may be changed. From above, the survey cannot be used as evidence.
To sum up, the arguer’s conclusion reached in this argument lacks credibility since all the reasons are not sufficient to support his assertion. He should take the given factors discussed above into account, if the town’s trash needs to be collected only once a week, and recently most people are actually not satisfied with EZ, then to choose ABC is a wise decision. On the contrary, if the town’s trash needs collection twice a week, and it is true that most people are satisfied with EZ, although EZ raised monthly fee from $2000 to $2500, it is still worthy. So, more survey are expected to draw the conclusion. |
