In this argument the author claims thatsince consumers are becoming more and more interested in growing vegetables,Green Thumb Gardening Center should expand the variety of vegetable seeds thiscoming spring to enhance their profits. Although at first sight the argumentseems to be appealing, it is in fact ill-reasoned, as discussed below.
To start with, the author simplygeneralizes from what is true across the nation to what must be true in onesmall region, yet he offers no cogent evidence to substantiate this crucialassumption. It is entirely possible that local people are very satisfied withthe vegetables available in supermarkets in spite of the national trend. Not tomention chances are that there is no such trend across the country, as we know nothingabout how the survey was conducted and whether it has a goodrepresentativeness. Another problem of this evidence lies in that even if localpeople are indeed unsatisfactory with the vegetables provided in supermarkets,it is still not necessary for them to grow vegetables by their own. They couldchoose to buy vegetables from groceries or drive cars to rural areas to makesome purchase from farmers. In sum, unless the author provide more specificevidence to confirm that none of these scenarios are possible, he can notconvince us that there are actually more local people growing their ownvegetables.
In addition, the author also assumes thatGreat Gardens being sold out at the village three months in a row indicating anincreasing number of people devoted in growing their own vegetables. Yet thisis not necessarily the case. It is entirely possible that Great Gardens is amagazine focusing on cultivating flowers, then how could the author concludesthat more people are interested in growing vegetables? Also, granted morepeople are curious about growing vegetables, there is no guarantee they will turntheir interest into action. And although the magazines seems to have been soldout quickly, if we take the possibilities that there is actually a limitednumber of issues, which means it took the magazine pretty a long time to besold out, we will no longer hold the view that gardening is popular in thisvillage.
Finally, even if evidence turns out tosupport all assumptions mentioned above, the author made too hastily aconclusion that expand the variety of vegetable seeds this coming spring couldbring them more profits. On the one hand, some special local climate features,like too hot, too cold, too dry or too much rain, may limit the vegetables viablehere to a certain variety. On the other hand, people with unique food culturemay have their own preference when deciding which kind of vegetables to grow. Expandingthe variety of vegetable seeds without investigation is a blind and dangerousas what the center picks may not to the local people’s taste. Besides, withoutweighting revenue against expense, the perception that this measure couldenhance profits is premature at best.
In conclusion, the argument is not soconvincing as it stands. In order to make it more persuasive the author hadbetter provide more valid evidence, reason more convincingly and take everypossible alternative explanation into consideration. |
