The total sales have increased by 20 percent since XXX added a pharmacy section to the grocery store. 这是因为提供了one-stop shopping. 所以建议在接下来的几十年多建一些别的铺，有clothes department、restaurant、还有什么shop.
原题：The following is part of a business plan created by the management of the Megamart grocery store:
“Our total sales have increased this year by 20 percent since we added a pharmacy section to our grocery store. Clearly, the customer’s main concern is the convenience afforded by one-stop shopping. The surest way to increase our profits over the next couple of years, therefore, is to add a clothing department along with an automotive supplies and repair shop. We should also plan to continue adding new departments and services, such as a restaurant and a garden shop, in subsequent years. Being the only store in the area that offers such a range of services will give us a competitive advantage over other local stores.”
是一个百货 做调查 加了一个 phmancy销量提升20% 所以得出结论 顾客更看重购物的方便性，所以应该 。。。 然后应该 增加new department 以增加 competitive advantage
[v2] 一个grocery shop去年增加了pharmacy section就导致了sales increase20%，所以一个人就说customers like one-stop shopping。 因此，要增加profit就要增加repair 还有一个什么部门(不记得了)，还有什么什么两个部门。。。
[v3] The total sales increased 20% after adding a pharmacy totheir grocery store. Because the customers like convenience of one-stopshopping, the manager thinks they should put clothing department to a hairsalon or restaurant…..
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.
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.
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.
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.
24：建议居民投资房产。因为过去5年房子的均价涨了一倍，而股票均价则是不断跌。因此，居民投资房产会比投资股票挣得多。此外，投资房产还能一边享受，一边挣钱(房价在涨)，而投资股票则不会contribute to quality of live.因此，居民都应该投资买房。
last year Apex manufacturing bought home computers and paid to telephone connections for its managers so that managers could get access to company file data and did additional work after normal business hours. And the productivity of APEX increased by 15%. 所以作者建议other companies也应该为员工在家里提供access to company resource，这样可以提高productivity以及increase profit.
原题：The following appeared as part of an article in a computer magazine.
”A year ago Apex Manufacturing bought its managers computers for their homes and paid for telephone connections so that the managers could access Apex computers and data files from home after normal business hours. Since last year, productivity at Apex has increased by 15 percent. Other companies can learn from the success at Apex: given home computers and access to company resources, employees will work additional hours at home and thereby increase company profits.”
Notice that only managers were bought computers by Apex, whose productivity indeed rose 15 percent as the result. It is different from the assumption made in the article, which stated that if all employees were brought computers, they would work extra hours at home. Managers ≠ all employees
A. This argument suffers from a fallacy of post hoc, ergo propter hoc.
B. Next, the author fails to provide any evidence that installing home computers for managers really led to the increase of Apex’s productivity.
1 home access 和increase productivity因果关系错误
4 hasty generalization。有两个，一是把apex推广到所有公司，二是把managers推广到了所有employees
In this article the author attributes Apex Manufacturing’s 15 percent increase in productivity over the past year to its decision to equip its manager with computers and paid telephone connections for their homes so that they would access company computers and files from home after normal business hours. On the basis of Apex’s experience the author recommends that other companies follow Apex’s example and provide computers and access to company resources to their employees. The author believes that such a policy would increase productivity and profits for other companies, just as it did for Apex. The author’s line of reasoning is questionable for several reasons.
First, the author assumes that Apex’s increase in productivity is due to its equipping its managers with home computers and access to company resources. However, the only evidence offered in support of this claim is the fact that Apex’s increase in productivity occurred after the home computers and after-hours access was provided. Unfortunately, this evidence is insufficient to establish the causal claim in question. While temporal precedence is one of the conditions required to establish a causal relationship between two events, by itself it is not a sufficient condition. Consequently, it is possible that Apex’s increase in productivity is not related to its decision to equip its managers with computers and after-hours access in the fashion required by the author’s argument.
Second, the author assumes that Apex and other companies are sufficiently similar to warrant a conclusion based on an analogy between them. Even if we accept the view that Apex’s increase in productivity was brought about by its policy of enabling its managers to work from home, differences between Apex and other companies could nullify this result. Lacking detailed information about Apex and the other companies in question it is difficult to assess the author’s conclusion.
In conclusion, the author’s argument is unconvincing. To strengthen the argument the author would have to provide additional evidence for the claim that Apex’s decision to provide its managers with home computers and access to company resources was responsible for its increase in productivity. Furthermore, it would be necessary to show that Apex and other companies are sufficiently similar to justify the analogy between them.
