GMAT新黄金80题及范文(九)

　　3. 以后是否还会有如此效果不一定。因为可能已经有企业提供更专业更优质的商品和服务。

　　2. 销售额增加不一定是profit增加。

　　3. 错误类比：就算加入了pharmacy引起了收入提高，也不能说增加的clothing和其他也会引起收入。很可能人们不是因为convenience，而是对medicine的需要。很可能其他的，人们更愿意到special shops。

　　The management of the Megamart grocery store concludes that adding new departments and services is the surest way to increase profits over the next couple of years. They are led to this conclusion because of a 20 percent increase in total sates, realized after the addition of a pharmacy section to the grocery store. On the basis of this experience, they concluded that the convenience of one-stop shopping was the main concern of their customers. The managements argument is faulty in several respects.

　　In the first place, the management assumes that the increase in total sales was due to the addition of the pharmacy section. However, the only evidence offered to support this conclusion is the fact that the addition of the pharmacy preceded the increase in sales. But the mere fact that the pharmacy section was added before the increase occurred is insufficient grounds to conclude that it was responsible for the increase. Many other factors could bring about this same result. Lacking a detailed analysis of the source of the sales increase, it would be sheer folly to attribute the increase to the addition of the pharmacy section.
