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.'

In this letter, the writer concludes that the Walnut Grove's town council is mistaken; we should continue using EZ. To support this conclusion, the writer points out that EZ collects trash twice a week, while ABC collects only once. He also cites that EZ has ordered additional trucks and he provides a survey, which shows that there are 80 percent of respondents were 'satisfied' with EZ’s performance. Careful scrutiny of the writer's letter reveals that the conclusion relies on several unproven assumption, and is therefore unpersuasive to some extent.
To begin with, the writer unfairly infers that the EZ is better than ABC because that it collects trash twice a week while ABC collects only once. The writer makes a mistake that the time of trash collection can't represents the efficiency of a company. Perhaps although the ABC collects trash only one time a week, it can provide a better service for citizens than EZ. Or perhaps, the EZ has to collect trash twice a week because that it doesn't try its best to do at the first time. Without ruling out these explanations, the writer can't convince me that EZ does a better job than ABC.有可能用的垃圾车的载量不同呢?
Secondly, the writer also concludes too hastily that the EZ will become better because it has ordered additional trucks. But this need not be the case, even if the EZ adds more trucks, it doesn’t mean that using these trucks can give a better service for the clients. The writer overlooks other possibilities that EZ is still worse than ABC if it doesn't increase the work efficiency of its company. So the writer makes a wrong assumption that is dubious.
In addition, the survey amounts to scant evidence of the writer's implicit conclusion that the respondents feel satisfied with EZ. But, whether the respondents were selected( in a random manner) at random词组 is open to doubt. Moreover, even if the result of survey is credited, the survey also can't support the writer's claim. Because, although the respondents were satisfied with EZ, when compared with ABC, they may feel more satisfied with ABC than EZ. 也就是没有进行横向比较In short, the letter's conclusion, which relies on this survey, is unwarranted.
To sum up, the writer's conclusion is logically unsound. To strengthen it, the writer should demonstrate that the EZ have a high efficiency and could provide better services than ABC. To better access this letter, I would need more information about that what is the respondents' attitude to ABC.
觉得你可能忽略一个点,就是有可能ABC的地理位置相对近些,还有调查的可靠性,那些增加车辆的的消息有可能是EZ的广告之词罢了 |
