In this argument, the author concludes that they at Green Themb Gardening Center can increase their profits by greatly expending the variety of vegetable seeds. To support this conclusion, he assumes that consumers are becoming more and more interested in growing their own vegetables by two evidences-a last-month national survey and the local sale of local gardening magazine表述很简洁.However,(加一个转折词比较好) I find this argument depend on several unsubstantiated grounds. First of all, to support the conclusion that people are interested in growing vegetables, one reason cited by the author is a national survey that, many consumers were dissatisfied with the quality of fresh vegetables in supermarkets. However, the extent of the survey is so wide that the consequence cannot stand for the attitude of local residents. On the one hand, perhaps local supermarkets always provide fresh vegetable to make consumers satisfied; on the other hand, admittedly(even if 会不会好一些) local residents dissatisfy with supermarkets, it is entirely possible that they turn to shop in the bazaars instead of supermarkets. Obviously either of these two possibilities would overthrow that conclusion that people interest in growing own vegetables. Therefore, unless the author rules out such conditions, the conclusion is not well supported. In the second place, the other reason for the interest in growing vegetables among consumers is a sale record that gardening magazine sold out at the Village news stand three months continuously. But when citing this evidence to support this argument, the author provides no information to prove that people buy this magazine in order to learn to grow vegetable. There is a substantiated possibility that this magazine do not teach people grow vegetable but take care of flowers or clip lawn. It may also be possible that the sale of this magazine is not pretty high while sale of others decrease largely in these months.(没太读懂) Boss’s assumption would make this conclusion so dubious. Therefore , the author should provide more information to strengthen his evidence. Finally, admittedly people interest in growing own vegetables, the author's assertion that the center can make profits by greatly expending the variety of vegetable seeds is unconvincing. Firstly, perhaps people would like to grow several kinds of vegetables, which lead the center falling because of expending variety of vegetable stock.(没懂) Secondly, possibly the great increasing of variety of seeds would also enhance the cost, and then as a result of it, the profits would largely descend.(第二个例子写成没有调查人们会选择什么样的种子,一味地增加品种和数量可能会导致经济损失。这样会好一点吧。) Thirdly, maybe there are several companies storing seeds in order to make profits. Then, with so many competitors, the profits would be compressed extraordinarily small. So without ruling out these conditions, this conclusion is unpersuasive. In sum, the assertion that the center would make profits make profits through vegetable seeds stock is not well supportive. To make this argument convincing the author should provide more substantiated evidences to prove the interest in growing vegetable from local residents. Besides, the author should more information to convince me that storing the variety of vegetable seeds would make large profits.
