The following appeared as part of a recommendation from the business manager of a department store:
"Local clothing stores reported that their profits decreased, on average, for the three-month period between August 1 and October 31. Stores that sell products for the home reported that, on average, their profits increased during this same period. Clearly, consumers are choosing to buy products for their homes instead of clothing. To take advantage of this trend, we should reduce the size of our clothing departments and enlarge our home furnishings and household products departments."
Discuss how well reasoned ... etc.
逻辑错误分析：
1. 错误类比(纵向)
1)主题句：The past three months’ trend does not guarantee the same in the future.
2)论据：三个月的时间是否能说明一种趋势?
2. 无理假设
1)主题句：Whether the reports of benefits from the local clothing stores and stores that sell products for the home are reliable or not are still open to doubt, thus making the author’ suggestion groundless.
2)论据：收益下降不一定跟产品种类有关。有可能是因为部门管理，部门员工效率等有关。
段落间的连接：
两个逻辑错误
1. 错误类比(纵向)》过去的状况和现在一样?
2. 无理假设》收益下降一定跟产品种类有关?
即使：
1. 即使收益的下降和产品的种类有关，那么过去的状况不能推到现在
2. 即使。。。更多相关内容请点击》GMAT写作备考侧重点分析。
The following appeared in a memorandum to the planning department of an investment firm:
"Costs have begun dropping for several types of equipment currently used to convert solar energy into electricity. Moreover, some exciting new technologies for converting solar energy are now being researched and developed. Hence we can expect that solar energy will soon become more cost efficient and attractive than coal or oil as a source of electrical power. We should, therefore, encourage investment in Solario, a new manufacturer of solar-powered products. After all, Solario's chief executive was once on the financial planning team for Ready-to-Ware, a software engineering firm that has shown remarkable growth since its recent incorporation."
Discuss how well reasoned ... etc.
逻辑错误分析：
1. 错误类比(横向)
1)主题句：The decrease of the cost of several types of equipment does not necessarily guarantee the reduction of the overall cost of the conversion of solar energy into electricity.
2)论据：
a. 设备价格的降低，并不一定是能源成本的降低。
b. 即使是能源成本的降低，也不一定会低于传统能源煤炭。
2. 错误类比(纵向)
1)主题句：The former performance of the CEO does not guarantee future success of the Solorio. From the author’s assertion, the CEO’s ability to manage this solar energy company is in fact somewhat dubious because he or she once was on the financial planning team for Ready-to-ware, which is in the industry completely different from the Solorio.
2)论据：
过去能取得成功并不代表将来还能取得成功，在不同的行业。。。。。。
段落间连接：
两个逻辑错误
1. 错误类比(横向)》设备成本的降低会导致相应设备所使用的能源成本降低。
2. 错误类比(纵向)》过去能取得成功并不代表将来能取得相同的成功，尤其是从事不同行业。
即使
1. 即使设备的成本低就会导致相应设备所使用的能源成本低，那么过去也不能推现在。
The following appeared in a memorandum from the Director of Human Resources to the executive officers of Company X.
“Last year, we surveyed our employees on improvements needed at Company X by having them rank, in order of importance, the issues presented in a list of possible improvements. Improved communications between employees and management was consistently ranked as the issue of highest importance by the employees who responded to the survey. As you know, we have since instituted regular communications sessions conducted by high-level management, which the employees can attend on a voluntary basis. Therefore, it is likely that most employees at Company X now feel that the improvement most needed at the company has been made.”
Discuss how well reasoned ... etc.
逻辑错误分析：
1. 错误类比(纵向)
1)主题句：The result of a last year’s survey does not necessarily represent the improvement most needed of this year.
2)论据：去年的想法不能代表现在还是这个想法。
2. 调查类错误
1)主题句：How was the survey held has not been illustrated by the author, thus making the conclusion groundless.
2)论据：调查的可信性：是否匿名的?如果要named，很可能并不是他们最想要改进的。
3. 无理假设
1)主题句：Whether the implement of the mentioned resolution is right or wrong is still unknown, it is still too early to say the improvement has been made.
2)论据：改进方法是否充分，是否会有很好的交流并且采纳意见。
段落间的连接
三个逻辑错误
1. 错误类比(纵向)>去年的想法不能代表现在还是这个想法。。。
2. 调查类错误》调查的可信性：是否匿名的?
3. 无理假设》改进方法是否充分，是否会有更好地交流，并且采纳意见。
即使：
1. 即使调查结果可信，那么去年的结果也不能用于今年。
2. 即使去年的调查结果能够代表今年员工的想法，那么方案也不一定就能取得效果。
