TOPIC: ARGUMENT17 - 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."

In this analysis, the arguer recommends that Walnut Grove town(WG) should still cooperate with EZ Disposal rather than ABC Waste. To justify the claim, the arguer compares the frequency of waste collecting and the number of trucks owned. In addition, he cites the result of last year's survey. The argument is unfounded because the arguer oversimplifies the problem and its solution.
To begin with, the arguer thinks EZ provides better service than ABC for it collects trash twice a week while ABC collects only once. However, it does not establish a general causal relationship between waste-collection frequency and the service quality, other possibilities have to be considered. For an instance, ABC may be much more efficient than EZ thus it only need to collect once a week while at the same condition ABC has to do twice.
拾两次的效果=拾一次的
Secondly, no evidence offered to support that all the ordered additional trucks will be used to collect the waste in Walnut Grove town. Perhaps those trucks are ordered for another town and will be used in WG by no means. Or that maybe many trucks now in EZ are too old to be used again so EA has to buy new ones to replace them. In this case we cannot infer that EZ will offer better service solely from the fact that EZ has ordered additional trucks.
新卡车不一定用在这里;也许该更换老的了
Finally, the result of this survey is far from enough to indicate that EZ provides exceptional service. First the arguer does not mention the total number of people participated in this survey, It is entirely possible that only a small proportion of residents have sent their feedback, thus their opinion cannot represent the residents' in WG as a group. Besides, those who sent their feedback, by accident, are those who like EZ more than that that dislike EZ. In shot, we need those people's personal information to judge the result's value.
没有总的数量;愿意回馈人的信息不知,样本也许不均匀
In conclusion, although the arguer have offered some evidence to support his or her recommend, none of them is sufficient. We still need more detailed information before we reach our conclusion
