Argument17 环保
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优越的 service: 80 percent of respondents to last year's town survey agreed that they were 'satisfied' with EZ's performance.
提纲:
1、提高价格的原因没有说明,而且上涨很高,必需作出合理的解释,也许正式价格上涨太多了,Walnut Grove's town council才会转向ABCA的;EZ提升后服务有没有变得更好也未知。
2、每周两次收集垃圾不一定必要,如果收集垃圾频率过高是不是会导致,每次车都没装满,这样就会造成浪费,从而导致多收钱。EZ购买新车,不代表能提供更好的服务,而且ABC也没有说不购入新车,什么时候购买新车也还是未知数。
3、调查的回应者不一定具有代表性,调查的真实性也值得考虑,而且居民未必对ABC就不满意。
正文:
The argument above presents a relatively sound case for arguing that we should continue using EZ, not choosing ABC Waste. However, by making a prudent scrutiny of this argument, we will find it suffers from several fallacies and therefore unconvincing. At least, there are some crucial factors that should be taken into account before drawing this conclusion.
Firstly, it is cannot be neglected that EZ has recently raised its monthly fee from $2,000 to $2,500 a month, whereas ABC’s fee is still only $2,000 every month. That means the price of EZ has apparently increased by 25%, which is not a small number. In addition, the arguer can not explain the reason that EZ made the decision about increasing its fee. It is highly possible that the service provided by EZ doesn’t improve or even is worse than ABC’s present service to some extent, albeit it has changed every month’s fee. Furthermore, the fact that EZ has raised its fee may be the most important reason, which leaded to Walnut Grove’s town council to advocate switching from EZ Disposal to ABC Waste.
Secondly, the arguer asserts that EZ collect trash twice a week, while ABC collects only once a week. Nonetheless, it is not necessary for EZ to collect twice every week and it is completely possible that high frequency will result in the amount of each trash truck fills is too small to waste the use of trash trucks. In other words, twice a week means that lower efficiency of using trash trucks and more money is charged. As for ABC, although it collects only once a week, it can also collect all trash to keep the town clean and it charges less money. In that case, the inhabitants in the Walnut Grove’s town may prefer ABC rather than EZ. Besides, the arguer claims that EZ has ordered additional trash trucks, while ABC currently has a fleet of 20 trucks. As far as I am concerned, there are at least two aspects needed to be considered. On the one hand, using more trucks to collect trash doesn’t equate the higher working efficiency. On the other hand, there is no evidence to show that ABC has provided awful service and will not supplement the new trash trucks in the future.
Finally, the arguer just depends on the survey that 80 percent of respondents agreed that they were ‘satisfied’ with EZ’s performance to support the conclusion that EZ provides exceptional service. Whether the survey reflects the reality, I mean, whether the respondents’ answerers represent their real opinions is uncertain, because they might be influenced by the surveyor. Were the respondents chosen random for the survey? And the what their opinions about ABC? It is possible that more than 80 percent of respondents really satisfy with ABC. Obviously, the arguer fails to take account the evaluation of the inhabitants in the Walnut Grove’s town giving to ABC. Therefore, without considering and eliminating these possible factors, the arguer cannot confidently bolster this conclusion.
In summary, this argument has several apparent fallacies which render it logically unpersuasive as it stands. To strengthen the argument, the arguer would need to provide clear evidence that EZ is really much better than ABC and worth to continuing using.
