GMAT作文：Argument范文精选（63）

　　Secondly， the speaker assumes that the low crop yields for first-time organic farmers last year are representative of crop yields for organic farmers overall. However， more experienced organic farmers might have had much better crop yields last year. Also， the first-time organic farmers might improve their own crop yields in future years. Moreover， last years yield may have been unusually low due to poor weather or other factors， and thus not indicative of future yields.

　　Finally， in asserting that organic farming is financially unwise because it is motivated by environmental instead of economic concerns， the speaker unfairly assumes that a practice cannot be both environmentally and economically beneficial. It is possible that， in the long run， practices that help protect the environment will also result in greater economic benefits. For instance， organic farming methods may better protect soil from depletion of the elements that contribute to healthy crops， providing an economic benefit in the long run.

　　In conclusion， the speakers argument is poorly supported and is short-sighted. To better evaluate the argument， we would need more information about the how the survey was conducted， especially about the comparison the survey makes. To strengthen the argument， the speaker must present evidence that last years crop yields from first-time organic farmers are representative of yields among organic farms in general. The author must also provide evidence that environmentally sound practices cannot be economically beneficial as well.
