1.
Compared to nonprofit hospitals of the same size, investor-owned hospitals require less public investment in the form of tax breaks, use fewer employees, and have higher occupancy levels. It can therefore be concluded that investor-owned hospitals are a better way of delivering medical care than are nonprofit hospitals.
Which one of the following, if true, most undermines the conclusion drawn above?


--FEIFEI98


key: Patients in nonprofit hospitals recover more quickly than do patients with comparable illnesses in investor-owned hospitals.


2. A society’sinfant mortality rate is an accepted indicator of that society’s general healthstatus. Even though in some localities in the United States
the rate is higherthan in many developing countries. In the United States , overall the rate hasbeen steadily declining. This declines does not necessarily indicate, however,that babies in the United  States are now, on the average, healthier atbirth than they were in the past.Which one of thefollowing reasons, if true, most strongly supports the claim made above aboutthe implications of the decline?
--FEIFEI125

key: The United States has been developingand his achieved extremely sophisticated technology for saving premature andlow-birth-weight babies, most of whom require extended hospital stays.
3.
Investigators concluded that human failure was not responsible for the fatal airplane crash last August, and since that time new and more stringent rules for identifying and reporting mechanical problems have been in effect. That accounts for the fact that reports of airplane mechanical problems have increased in frequency by 50 percent since last August.
Which one of the following is an assumption underlying the argument in the passage?


--FEIFEI61


key: Mechanical problems in airplanes have not increased by 50 percent since last August.


4.
A survey of alumni of the class of 1960 at Aurora University yielded puzzling results. When asked to indicate their academic rank, half of the respondents reported that they were in the top quarter of the graduating class in 1960.
Which one of the following most helps account for apparent contradiction above?


--FEIFEI105


key: A disproportionately large number of high ranking alumni responded to the survey.

No.45 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.”

premise: 加了草药department， 销售量变高了+顾客看重买东西的方便性   conclusion: 应该加上衣服，食品等更多的department，销量肯定还会增加
1）pharmacy与蔬菜的保存条件类似，所以可以加；但是其他食品，衣服……不适合与蔬菜处于同一环境保存
2）加太多department的cost 大于增加获得的利润

P: the sales of the store have increased by 20% since the open of pharmacy section
P: customer’s main concern is the convenience afforded by one-stop shopping
C: therefore the store should add clothing department and other new services like restaurant and a garden shop to increase profits, and gaining the competitive advantage of having various services in a single store
Attack:
1.        错误假设: the 20% sales increase might not necessarily because of the pharmacy department. It might result from other reasons, eg, stores’ marketing strategies, larger population of the area, and bankrupt of other pharmacies in the area.
2.        错误类比: the increase of 20% sales because of the open up of the pharmacy department might not apply to other services including clothing, restaurant and garden. The sales jump might because of lack of pharmacy in the region, or lower prices of the store, or better services and doctors provided by the store. However, there might be many clothing, restaurant and garden services nearby, dragging the new sections in fierce competition and not guarantee high paybacks of the new departments.
3.        错误假设: more departments may not guarantee higher profits and competitive advantages. The author ignore the starting-up expenses of the new sections and complexity and higher management expenses generated by more services.
4. ignore the inconvenience added by more services, which drive away customers who want exactly specific services but not a range of complicated service in one store, which might be time and money consuming.

P: investor-owned hospitals require less public investment, few employees, and have high occupancy levels, compared with nonprofit hospitals
C: Therefore investor-owned hospitals deliver better medical care.
【因果】假性因果。文章错误滴把investment, employee, occupancy level和medical care quality 因果联系在一起。
削弱，就是指出两个没有因果关系。Less public investment, fewer employees, and higher occupancy levels not necessarily bring higher medical care. 或者直接削弱结论，investor-owned hospitals not provide better medical care

2. 36’
P: the infant mortality rate is an indicator of society’s health status
P: the overall mortality rate is declining
C: however the decline do not represent that babies in US are healthier than before
【差异】婴儿的死亡率是社会健康的标志，最近整体的死亡率下降了，但是不表示婴儿比以前更加健康
The United States has been developing and his achieved extremely sophisticated technology for saving premature and low-birth-weight babies, most of whom require extended hospital stays. 美国的科技可以救早熟的和低于正常体重的婴儿，大多数的这些不正常婴儿需要更长的住院时间。
所以死亡率降低，只是因为有更好的科技了

3. 44’

P: new and more stringent rules have been in effect since last August

C: therefore the 50 percent increase in airplane problems were caused by the new rules, but not human failure

【因果】因为去年八月新的严格规定颁布了，所以增加的飞机问题是因为新的规定，而不是人为。这里把同时发生的新规定和增加的错误定位因果关系。

假设，就是规定是唯一原因，人为没有影响。没有他因。The new rules are the only reason for the increased problems, and no reasons including human failure are account for that.

4. 33’

P: half of the alumni indicated that there were in the 1/4 of the graduating class

【差异】一半被调查的毕业生说当时他们在top 25%。出现调查，就要怀疑调查的代表性。或许调查的都是好学生，所以一半的人都是top 25%里面的，没有任何理由说明被调查的就是平均分布的。

Explanation: half of the alumni surveyed were in the top 25%, or only the top alumni were selected to join the survey, or only those who were good students were responded to the survey….

P: The fact that graduates who graduated in 1960 yielded a puzzle.
C: The half graduates who did the survey responded their academic is among the top of 1/4.
Resolve: Most top students did survey

5. 30‘
P: sales increased after added pharma section
C: Add clothes dept, restaurant, garden shop to increase sales
Weaken: pharma is different from clothes dept etc, pharma success doesn’t mean clothes dept will get success
2 Add more means more tax, wont get more profits
3. Only one store? Other stores will do the same

BG：与非盈利医院相比，投资医院需支付更少的tax break，有更高的occupancy level，（。。好吧我又忘了中间那个）。
Conclusion: 因此可以推论有更好的医疗条件.

Weaken: Which one is better cannot be judged through these three factors.. ehmmmm investor-owned hospital might sacrifice medical care in interest of their own profits?

2. 65s
BG：婴儿夭折率是一个判断社会健康水平的重要指标。美国当地有些地方的婴儿夭折率甚至高过发展中国家。
Premise: 去年美国的夭折率下降了
Argument： 但这并不能说明美国宝宝健康状况有好转。

Strengthen: 美国婴儿出生率也同步下降。

BG: 调查人员下结论说，八月份的重大坠机事件不是由于人员失误造成的。
Premise: 之后出台了新的更加严格的条例规定检查并上报机械问题。
--》于是八月份的机械故障报告上升至50%

Assumption: （其实我没搞清楚这道题的Argument到底是什么，是investigator的话么？如果是的话：。。）
所有上报的机械问题都得到了排查？

1960届A大毕业的校友参与的一个调查出现了一个让人迷惑的结果。
超过半数的人认为他们自己的在同届毕业生中的学术排名应该是靠前的1/4。

Solve the paradox: A大采取鼓励为主的教学方针，当时并没有给他们具体排名，而是暗示大家排名不错。
（看答案了我晕：我忽视了参与调查的人数问题）

杂货店：
BG：咱们去年的销售业绩上升了20%，由于我们添加了药品区。
-》顾客喜欢一站式服务带来的便利。因此在未来几年内，我们想要继续增加营业额，那么就应该继续扩充业务。明年我们要继续增加服装部、汽车配件修理部。在未来几年内我们要增加餐饮，还有花园用品等等。在这个片区内，我们成为了唯一拥有如此庞大范围的超市，一定会更具竞争力的！

Flaw : 药品成功也许是由于该片区缺少药店。若服装、汽车配件、餐饮、花园用品等这些业务在该片区已经相当成熟且竞争激烈，增加业务未必能带来收益。
