argument137 【loveaw】第四次作业 TOPIC: ARGUMENT137 - The following appeared in an editorial in the Mason City newspaper.
"At present, Mason City residents seldom use the nearby Mason River for any kind of recreational activity, even though surveys of the region's residents consistently rank water sports (swimming, fishing, and boating) as a favorite form of recreation. Since there have been complaints about the quality of the water in the river, residents must be avoiding the river because they think that it is not clean enough. But that situation is about to change: the agency responsible for rivers in our region has announced plans to clean up Mason River. Therefore, recreational use of the river is likely to increase, so the Mason City council will need to increase its budget for improvements to the publicly owned lands along the Mason River."

In light of a questionable survey and several unsubstantiated assumptions, the author comes to the conclusion that recreational use of Mason River will probably increase and thus local council should increase its budget for improvements to the publicly owned lands along the river, which is unsound as it stands.
(另一个版本的开头,不过好像没啥区别The author comes to the conclusion that recreational use of Mason River will probably increase and thus local council should increase its budget for improvements to the publicly owned lands along the river. However, based on some unsubstantiated assumptions and a dubious survey, the conclusion is unsound as it stands.)
To begin with, the author fails to prove that the survey is statistically reliable. In the survey quoted in the argument, no sign of such procedure for random sampling can be found, and there is a good chance that the sample of survey is not representative enough to reflect the general attitudes of overall local inhabitants as a whole. Also, it is entirely possible that the survey is somewhat misleading so that the respondents have to choose water sports as a favorite form of recreation. Failing to substantiate the reliability of the survey, the author cannot convince me that local residents prefer water sports to other forms of recreation.
In addition, the author lends no support to the claim that the situation is about to change. The author provides no evidence that the agency responsible for rivers in their region is going to implement their plans to clean up Mason River. Moreover, even the agency will take measures to clean up the river, the argument leaves open the possibility that the consequence of the plans implemented is so dissatisfactory that local residents remain discontent with the quality of the water in the river and thus keep themselves away from it.
Finally, the author provides no evidence to support the claim that recreational use of the river is likely to increase. Assuming that a growing number of local citizens will go to the river for recreation, the author,however, fails to take into account the possibility that local residents inclined to swimming can go to a swimming pool to swim, which is an alternative of the river, and that therefore recreational use of the river will not increase. Without ruling out such possibility, the conclusion that the council should invest more in improvements to the publicly owned lands along the river is unsound.
In sum, the conclusion is dubious at best on the basis of a questionable survey and several unsubstantiated assumptions. To better assess the argument, it would be of use to know the credibility of the survey and further specific information concerning current recreational use of the river. |
