题目：ARGUMENT67 - The following appeared in a letter to the editor of a newspaper serving the villages of Castorville and Polluxton.
"Both the villages of Castorville and Polluxton have experienced sharp declines in the numbers of residents who pay property taxes. To save money and improve service, the two villages recently merged their once separate garbage collection departments into a single department located in Castorville, and the new department has reported few complaints about its service. Last year the library in Polluxton had 20 percent fewer users than during the previous year. It follows that we should now further economize and improve service, as we did with garbage collection, by closing the library in Polluxton and using the library in Castorville to serve both villages."

论点：关闭P村图书馆，两村一起使用C村图书馆
论据：1.两村合并了垃圾回收部门，以节省开支和提高服务。
2.新部门据报道投诉者少
3.P村图书馆去年比以前减少20%的使用者
反驳论据：1. 新部门的真实服务水平值得怀疑。
2. 类比错误。
In this argument, the arguer recommends that village P should close its library and use the substitute one in village C, reasoning that both of the villages will benefit from saving money and improving service.
To justify the conclusion, the arguer makes an analogy between garbage collection service, which have been merged into a single department, and library service, which owns few users in P. As it stands, however, the argument suffers from several critical flaws, as follows.
A first assumption about all villagers' content about the service provided by the newly merged garbage collection department is needed to justify the intermediate conclusion. For that the arguer only points out that few complaints have been reported about its service, yet no evidence is stated that opinions of all the residents in both villages have been collected. Provided that merely a small proportion, say 20%, of villagers have participated the poll of their attitude about the service, the sample actually is insufficient, thus the report is suspicious. Only by explicating the concrete percentage of residents' satisfaction, does the arguer would be able to hand in a valid statement.
Well, the second assumption that the number of users of P's library will also declined this year as it in last year lacks credibility as well. In virtual, we are not given enough information to be sure that this comparison is reliable. Consider, for instance, a part of young villagers of P went out for making money last year, leading the decline of the constant residents in P. Thereby, since the total population was smaller than previous, the users certainly to be fewer. But this year whether these young men will work out or not is unknown, it is unwise for the arguer to unfairly assumes that library in P will be a waste of money.
Moreover, if the intermediate conclusion that majority of residents in both villages satisfied with the new department's service, a third assumption about the similarity of garbage collection service and library service is still needed to justified the final conclusion. It is highly doubtful that the facts drawn from the garbage collection service are applicable to the library service. Differences between the two services clearly outweigh the similarities, thus making the analogy less than valid. For example, problems of inconvenient use of
residents in P, transportation between P and C, all affect the library service, but are virtually absent in the garbage collection service. Problems such as these might arouse complains of villagers of P that resultant degrades the service.
To conclude, the argument is not persuasive as it stands. To make is more convincing, the arguer would have to provide more evidence concerning the sufficiency of utilization of P's library and whether it will affect residents' living quality. |
