GMAT考试写作参考例文 The following appeared in a memorandum from the ElectroWares companys marketing department. Since our company started manufacturing and marketing a deluxe light bulb six months ago, sales of our economy light bulband company profitshave decreased significantly. Although the deluxe light bulb sells for 50 percent more than the economy bulb, it lasts twice as long. Therefore, to increase repeat sales and maximize profits, we should discontinue the deluxe light bulb. Discuss how well reasoned . . . etc. In this memorandum ElectroWares marketing department reasons that manufacturing and marketing of the companys deluxe light bulb should be discontinued. The primary factors that influence their decision are a significant decrease in sales of the companys economy light bulb as well as declining company profits in the six month period following the introduction of the deluxe bulb. Presumably, their line of reasoning is that the introduction of the deluxe bulb is responsible for both of these undesirable outcomes. Unfortunately, the marketing departments rationale is problematic for several reasons. In the first place, the marketing department has engaged in after this, therefore because of this reasoning. The only reason offered for the belief that the introduction of the deluxe bulb is responsible for both the decline in sales of the economy bulb and the decline in company profits is the fact that the former preceded the latter. No additional evidence linking these events is provided, thus leaving open the possibility that the event are not causally related but merely correlated. This in turn leaves open the possibility that factors other than the one cited are responsible for the decline in sales of the economy bulb and the decline in company profits. |
