21．是说W城本来是以旅游业为主，但是因为工业污染，national parks就变得很没有吸引力，所以去参观的人就少了。但是最近发现在一些公园里有很丰富的煤矿，所以只要政府批准mining company去开采的话，利润（很清楚，说的是revenue）就会上升，而且会提供工作给那些之前在干旅游业的人。（请知道原始的同学站短我，O(∩_∩)O谢谢）

22．The following appeared in an editorial from a newspaper serving the town of Saluda.
“The Saluda Consolidated High School offers over 200 different courses from which its students can choose. A much smaller private school down the street offers a basic curriculum of only 80 different courses, but it consistently sends a higher proportion of its graduating seniors on to college than Consolidated does. By eliminating at least half of the courses offered there and focusing on a basic curriculum, we could improve student performance at Consolidated and also save many tax dollars.
题库号码：105
提纲：
1.        causal oversimplification
2.        false analogy
3.        It is likely that the smaller private school is incapable of offering more courses, or else its students can have better performance.

23．The following appeared in the editorial section of a campus newspaper.
“Because occupancy rates for campus housing fell during the last academic year, so did housing revenues. To solve the problem, campus housing officials should reduce the number of available housing units, thereby increasing the occupancy rates. Also, to keep students from choosing to live off-campus, housing officials should lower the rents, thereby increasing demand.”

提纲：
1，        入住率低可能是因为学生人数减少等原因造成的
2，        同时减少供给和降低房费可能会抵消入住率提高而带来的收入提高效应而有余
3，        就算不会完全抵消仍然有其他原因影响收入例如说学生进入后的维修等等。

1，        忽略他因：单纯地说问题所在是rent. 但实际上可能有很多其他的因素：房子的condition, security, cleaning service，noisy surroundings等等。
2，        过去不能推广到未来：很可能变化了——比如enrollments of students have sharply increased。所以，很可能减少available的数量可能不是合适的做法。
3，        减少提供的房子，降低房租，很可能导致收入下降。

25．The following appeared in the opinion column of a financial magazine.
“On average, middle-aged consumers devote 39 percent of their retail expenditure to department store products and services, while for younger consumers the average is only 25 percent. Since the number of middle-aged people will increase dramatically within the next decade, department stores can expect retail sales to increase significantly during that period. Furthermore, to take advantage of the trend, these stores should begin to replace some of those products intended to attract the younger consumer with products intended to attract the middle-aged consumer.”
题库号码：9
提纲：
1.        The absolute value of consumption should be given by the author.
2.        all things are equal
3.        Whether the increase of profit gained by attracting more middle-aged consumers will be offset
4.        by the reduction of profit because of the loss of young consumers.

26．The following appeared in the editorial section of a local newspaper.
“This past winter, 200 students from Waymarsh State College traveled to the state capitol building to protest against proposed cuts in funding for various state college programs. The other 12,000 Waymarsh students evidently weren’t so concerned about their education: they either stayed on campus or left for winter break. Since the group who did not protest is far more numerous, it is more representative of the state’s college students than are the protesters. Therefore the state legislature need not heed the appeals of the protesting students.”

提纲：
1.        代表学生的形成方式不知道。如果是随机产生的，那么去反对的学生完全可以代表学生总体。
2.        没去的学生不一定不关心。他们可能有更重要的事情要忙。例如要赶回家过圣诞节。有已经订好的寒假计划等等。
3.        此外，没去的学生之所以没有去很可能是因为他们觉得那些代表足可以代表他们表达心声。

28．The following appeared as part of an article in a magazine devoted to regional life.
“Corporations should look to the city of Helios when seeking new business opportunities or a new location. Even in the recent recession, Helios’s unemployment rate was lower than the regional average. It is the industrial center of the region, and historically it has provided more than its share of the region’s manufacturing jobs. In addition, Helios is attempting to expand its economic base by attracting companies that focus on research and development of innovative technologies.

提纲：
1.        作者认为应该到该地区建厂理由是这里的失业率很高。但是却没有给出因果关系。从常理来看这是没有道理的因为失业率高的地方可能更难雇佣到雇员从而使成本增加。
2.        作者认为该地区会鼓励研发，所以应该到该地区投资。但事实上就象作者说的那样该地区是制造业中心怎么可能有很多对技术和科研很熟练的人员。

1，        因为H地区industrial and manufacturing比较attractive，所以那里的工人很可能只适合做这类的，如果缺乏能够做innovative technologies and research的工人labor pool，那么很可能导致失败。
2，        H的低失业率更可能成为坏处。因为比如有less available work force。企业必须提高wage才能吸引他们。提高了COST。
3，        错误的假设过去的成功能够代表未来。比方说已经饱和的资源、过分的竞争、以及可能出现的错误政策，都可能导致H地区的经济不再发达。

29：The following appeared in an article in the health section of a newspaper.
“There is a common misconception that university hospitals are better than community or private hospitals. This notion is unfounded, however: the university hospitals in our region employ 15 percent fewer doctors, have a 20 percent lower success rate in treating patients, make far less overall profit, and pay their medical staff considerably less than do private hospitals. Furthermore, many doctors at university hospitals typically divide their time among teaching, conducting research, and treating patients. From this it seems clear that the quality of care at university hospitals is lower than that at other kinds of hospitals.”
题库号码：:43
提纲：
1，        从一个医院的情况就推广到整个太草率
2，        治愈率低可能是因为接受的患者得的病都比较罕见等原因造成的
3，        工资低，总体利润低，时间分配给教学都不能一定说明质量差。可能其他福利好，接受的病人少，教学研究有助于进步

1.        首先，医生的人数与质量之间没有必然的因果原因。profit跟质量也无关系。很可能treating price is significantly lower。
2.        成功率不能说明问题。缺乏其他的证据，忽略了他因：比如因为质量高，所以很多serious illness的，而送往其他医院的一般都是common cases.
3.        时间不能代表问题。因为那些医生所做的研究很可能帮助他们进行治疗。

30：Airline去年的赢利下降了10%。 去年油价上涨了，同时此公司在去年新开了五个航班（flights）。 但是虽然去年油价上涨，其他一些航空公司的赢利却没有下降，因此油价并不是公司盈利下降的原因。由此可知问题出在五个新增航班上，因此公司应当取消（eliminate）这些航班。
