14.The following appeared in a memo from the owner of Green Thumb Gardening Center, a small business serving a suburban town.
"There is evidence that consumers are becoming more and more interested in growing their own vegetables. A national survey conducted last month indicated that many consumers were dissatisfied with the quality of fresh vegetables available in supermarkets. And locally, the gardening magazine Great Gardens has sold out at the Village News stand three months in a row. Thus, we at Green Thumb Gardening Center can increase our profits by greatly expanding the variety of vegetable seeds we stock for gardeners this coming spring."
有证据表明消费者对于自己种植蔬菜越来越感兴趣。上个月举行的一项国家调查显示很多消费者对于超市上供应的新鲜蔬菜的质量不满意。在本地,园艺杂志《大花园》在"Village News"报亭连续三个月售磬。因此,我们Green Thumb Gardening Center可以通过大量增加今春为园艺爱好者准备的蔬菜种子的种类而增加盈利。
The argument concludes that Green Thumb Gardening Center can increase profits by expanding the variety of vegetable seeds .To support this conclusion the speaker sites a national survey and the sale of a gardening magazine as evidences of people prefer to grow their own vegetables However, close scrutiny of this evidence and of the auger’s line of reasons that reveals that they provides little credible support for the conclusion.
One problem with the argument is that the memo depends on the assumption that the level of satisfaction locally with supermarket‘s fresh vegetables reflects national levels by relying on the national survey to support its conclusion. Yet the owner provides no evidence to support this assumption. Maybe, the residents of this town are satisfied with supermarket‘s fresh vegetables, or they have another methods to get high quality fresh vegetables such as buying vegetables from special produce markets or vegetable stands .Without eliminating these possibilities, the owner cannot rely on the national survey to conclude that this town’s residents would be interested in growing their own vegetables and prefer to buy vegetable seeds from GT.
Another problem with the memo is that the mere fact that the gardening magazine Great Gardens has sold out at the Village News stand three months in a row is scant evidence that the town’s residents would be eager to buy vegetable seeds from GT. Firstly, the arguer fail to provide any evidence to support the circulation of the magazine is large enough and perhaps this newsstand decreased the number of copies it stocks three months ago. Secondly, the owner shown nothing about the contents of this magazine, maybe it does not even concern itself with vegetable gardening. Thirdly, even the residents buy this magazine is interesting in vegetable gardening, the owner provides no clear evidence that residents will grow their own vegetables practically.
Finally, even if residents will growing their own vegetables practically, the arguer assumes too hastily that the residents would like to buy seed form GT and that GT can increase their profits by expanding the variety of vegetable seeds. It is possible that the residents have other alternatives to buy vegetable seeds, or in the town people just like eat some certain vegetables, expanding the kinds of seeds have no help in increase GT’s profits.
In conclusion, the argument of the GT owner is logically flawed and therefore unconvincing as it stands. To strength it the owner must provide more clear evidences that residents of the town are actually dissatisfied with supermarket vegetables, and provide more information about the gardening magazine ,its circulation,its contents , and the residents’ purpose buying the gardening magazine to support that they are becoming more and more interested in buy vegetable seeds from GT in order to grow their own vegetables.
