1The following appeared in a memorandum written by the vice president of Nature's Way, a chain of stores selling health food and other health-related products.

        "Previous experience has shown that our stores are most profitable in areas where residents are highly concerned with leading healthy lives. We should therefore build our next new store in Plainsville, which has many such residents. Plainsville merchants report that sales of running shoes and exercise clothing are at all-time highs. The local health club, which nearly closed five years ago due to lack of business, has more members than ever, and the weight training and aerobics classes are always full. We can even anticipate a new generation of customers: Plainsville's schoolchildren are required to participate in a 'fitness for life' program, which emphasizes the benefits of regular exercise at an early age."

　　Merely based on the unfounded assumption and suspicious evidence, the statement draws the conclusion that the products of Nature’s Way will sell well in Plainsvile. To substantiate this conclusion, he points out the evidence that the number of people who go to health club and other such places has increased .In addition, he cites a recent report that running shoes and exercise clothing sells well at the same time. At first glance, this argument seems to be somewhat convincing, but further reflection reveals that it omits some substantial concerns that should be addressed in the argument. From the logical perspective this argument suffers from 4 logical flaws.

　　The threshold problem with this argument is that the increasing number of the sales volume of the shoes and exercise clothing can’t prove that physical exercises are popular, maybe the price of these goods in Plainscile is cheap at all times, which attracts customers to go shopping frequently. Even people here are crazy about sport, we can’t figure out that the selling of health food would also be successful(这个才是FA错误), maybe taking some sport exercises is enough for them, and health food is a fashionable but unfamiliar thing to them, consequently they may not accept it.

　　Another problem that weakens the logical of this argument is that there might be other same companies that have done this business for years, which may be great challenge to the arguer’s company-local people may not accept an unfamiliar company. Just as the arguer said, five years ago the huge failure of that local club was made possible by tough competition. Even assuming that Nature’s way take a firm stand in Plainsville, competitors make price at a lower level , and the company may not get the desirable profit.

　　Before I come to my conclusion, it is necessary to point out the last flaw involved in this argument that Previous experience may not apply to the current situation, great changes may have taken place in Plainsville within 5 years, the arguer fails to analyze the differences between now and ever, arbitrarily get the conclusion, which may be an false analogy.(这个不是FA错误，而是时间外推类错误,可以用hasty generalization)

　　To sum up, this arguer fails to substantiate his claim that the products of Nature’s Way will sell well in Plainsvile. Because the evidence cited in the analysis does not lend strong support to what the arguer maintains. To make the argument more convincing, the arguer should offer more proves that the product of Nature's Way is fit for the local people, if the argument had included this, the argument would have been more through and logical acceptable.

　　模板语言非常地道，但是中间对于逻辑错误的攻击不够饱满。并且没有按照最优的攻击顺序（让步式攻击）进行。
　　例如，可以这样安排：先攻击因果类（或充分必要条件）错误，再攻击时间外推，最后攻击错误类比。此外，profit利润类问题可以安插GMAT写作经典思路:开新店需要品牌成本（brand cost)。需要多做题，多练习。对于攻击顺序的把握是靠多练习来积累的。攻击的错误不在多（3个就够了），但一定要说透！不能点到即止。
