　　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 management’s argument is faulty in several respects. 来源：考试大

      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.来源：考试大

      In the second place, even if it were the case that the increase in total sales was due  to the addition of the pharmacy section, this fact alone is insufficient to support the  claim that adding additional departments will increase sales even further. It is quite  possible that the addition of the pharmacy section increased sales simply because there  was no other pharmacy in the vicinity. The additional proposed departments and  services, on the other hand, might be well represented in the area and their addition  might have no impact whatsoever on the profits of the store. In other words, there may  be relevant differences between the pharmacy section and the additional proposed  sections that preclude them from having a similar effect on the sales of the store. 来源：考试大

      In conclusion, the management’s argument is not well-reasoned. To strengthen the  conclusion, the management must provide additional evidence linking the addition of  the pharmacy section to the increase in total sales. It must also show that there are no  exceptional reasons for the sales increase due to the pharmacy section that would not  apply to the other proposed additions.
