The arguer concludes that the profits would be increased in GTGC by expanding the variety of seeds stocked for gardeners this coming spring .To bolster this assertion the arguer cites a national survey with respect to the evaluation for vegetables in supermarkets. The arguer also
points out that a gardening magazine has sold well.  However, although the conclusion sounds indeed reasonable at first thought, a series of unsubstantiated assumptions and several logical flaws may seriously undermine this argument.

To the first, the survey cited by the author is too vague to be informative. The author does not provide information concerning how many people responded to the survey and whether the respondents can represent all people. For example, were the survey respondents forthright?  Did the respondents include the people in the city where the GTGC locates? Besides,we are told nothing about the way the survey was conducted and how well it represented the local people's opinions. Until these questions are answered, it is impossible to assess the validity and reliability of the survey. Even though the survey can be convincing, the consumers' evaluation, of which dissatisfied with the quality of fresh vegetables in supermarkets,does not mean that they are interested in growing their own vegetables. It is certainly possible that the quality of supermarkets' vegetables has decreased. Therefore, the national survey can not be a significant evidence to support the conclusion.

Secondly,the author fails to assert that the consumers become to like growing vegetables by themselves just by the fact of the hot of a magazine named GG. Beside the interest in growing vegetables, there are plenty of reasons cause the situation.For instance, the articles in the magazine in these three months were so attractive that the readers increased. And I realize that GG only sold out at the Village News stand,what about other stands?If  the GG did not sell well in other stands, we can not conclude the magazine is popular and say nothing of the author's assertion.

Thirdly, even the people really become to like growing vegetables, the author falsely created a gratuitous assumption that the expanding the variety of vegetable seeds provided to gardeners can increase the profits, since no evidence support this assumption.He can not assert that with his own experience or personal idea. For example,how can he ensure the gardeners would buy vegetable seeds in his center, maybe some kinds of the seeds would be ignored by people. Facing
the condition, whether the profits would increase can not be predicted.

Since the author commits the above mentioned logical mistakes and fails to consider all the problems comprehensively, his recommendation should not be effective. If he wishes his recommendation to be of any value, he has to prove that the survey is persuasive, and the consumers really like growing vegetables, and so on.
