1. 大全TEST21 -1
One state adds a 7 percent sales tax to the price of most products purchased within its jurisdiction. This tax, therefore, if viewed as tax on income, has the reverse effect of the federal income tax: the lower the income, the higher the annual percentage rate at which the income is taxed.
The conclusion above would be properly drawn if which of the following were assumed as a premise?
Answer: The amount of money citizens spend on products subject to the state tax tends to be equal across income levels.
2. 大全TEST21-2
The average age of chief executive officers (CEO’s) in a large sample of companies is 57. The average age of CEO’s in those same companies 20 years ago was approximately eight years younger. On the basis of those data, it can be concluded that CEO’s in general tend to be older now.
Which of the following casts the most doubt on the conclusion drawn above?
Answer: The information is based only on companies that have been operating for at least 20 years.
3. 大全TEST21-6
Radio interferometry is a technique for studying details of celestial objects that combines signals intercepted by widely spaced radio telescopes. This technique requires ultraprecise timing, exact knowledge of the locations of the telescopes, and sophisticated computer programs. The successful interferometric linking of an Earth-based radio telescope with a radio telescope on an orbiting satellite was therefore a significant technological accomplishment.
Which of the following can be correctly inferred from the statements above?
Answer: The location of an orbiting satellite relative to locations on Earth can be well enough known for interferometric purposes.
4. 大全TEST21
The value of a product is determined by the ratio of its quality to its price. The higher the value of a product, the better will be its competitive position. Therefore, either increasing the quality or lowering the price of a given product will increase the likelihood that consumer will select that product rather than a competing one.
Which of the following, if true, would most strengthen the conclusion drawn above?
Answer: Consumers’ perceptions of the quality of a product are based on the actual quality of the product.

AA: 我们来写机经吧！~oh, yeah!
JJ 第二篇~
The following appeared in a presentation by the chief production manager of a machine parts manufacturing company at a management meeting:
“Our factory in Cookville is our most advanced and efficient. It is capable of producing ten drill bits for each dollar of production costs, whereas none of our other factories can produce more than seven drill bits per dollar of production costs. Therefore, we can reduce our overall drill bit production costs by devoting the Cookville factory entirely to drill bit production. Since reducing the production costs of individual machine parts is the only way to achieve our larger goal of reducing our overall production costs, dedicating the Cookville factory entirely to drill bit production and shifting all other machine part production to our other factories will help us to attain that larger goal.”

1. 45s
BG: 某州决定在其管辖范围内征收7%的销售税。
Conclusion：如果把它看做是收入所得税的话，在联邦内起到相反的影响，即：则纳税者收入越低，其纳税的金额比例占其总收入就越高

Premise: 征收消费税的那些产品，在收入水平同等的情况下，消费者的消费水平是差不多的。

2. 20s
Premise: 抽样的公司中CEO平均年龄是57岁，而20年前还是这些抽样公司，它们的CEO平均年龄要年轻8岁。
Conclusion: 所以整体CEO的年龄都有变老的趋势。

Weaken：这些抽样的公司不具有代表性（都是至少经营了20年以上的）

3. 超时
声波探测是一项结合声波望远镜来探测天上物体的技术。要求声波望远镜，详细定位和复杂的电脑编程。
因此，在地球上安装这个探测设备，然后再有轨道的卫星上安装，应该是一项重大的科技成就。
Inference：定位轨道卫星是一项本来很艰巨又很关键的任务。

4. 32s
BG：一个产品的价值取决于产品的质量与其价格的比。产品价值越高，那么它与同类产品的竞争力就越强。
Conclusion: 因此要么提高质量，要么降低价格，这样能增加消费者选择一个产品而不选其他产品的倾向性。

Strengthen：消费者对于产品质量的判断不会有偏差。

Premise: new tax on purchase
Conclusion: The lower the income, the higher the tax rate
Assumption: they spend same on product

2. 15’
Premise: 20 years ago, they are 8 years younger, now older
Conclusion: CEO tends to be older
Weaken: these CEO get older after 20y

3. 46’
Premise: RI combines SI, require …
Conclusion: T        with RT is important for RI
Infer: 不会

4. 25’
Premise: The value is determined by quality / price
Conclusion: Either improve quality or lower price will give products competitive edge
Assumption: People decide if buy the production on the value

5.30’
Premise: C drill more than other, C drill all will reduce cost, reduce cost is the only way to achieve larger goal
Conclusion: C drill all and shift all other to other factories will attain larger goal
Weaken: 1 drill more doesn’t mean cost less
       2 shift will cost money

P There is a 7% purchase tax in the city.
P If view this tax as the tax on income.
C Therefore, this tax has reverse effect on the federal income tax.
assumption: ???
2 28s
P The average age in a sample group is 57.
   The average age in the same company 20 years ago was younger.
C  In general, CEO tend to be older now.
doubt: Wheter the sample is representative?

P The I technique studies...
P This technique requires...
C This technique is a great breakthrough.
inference:
4 41s
P The value of a product is determined by the ratio of quality and price. The higher is the value, The more competitive the product is.
C either increase the quality of decrease the price will make customers buy the products.
strengthen: The competitors do not take the same measures.

5 AA
It is imprudent to conclude that the factory in C is most efficient and advanced because of they produce 10 drill bits for each dollar of production cost.
Giving too much pressure on C may diminish its productivity.
There are other ways to achieve the goal.

Background info: state adds a 7 percent sales tax for the goods.
Conclusion: this sales act as an income tax, and the lower class people are charged higher level of tax than upper class.

Fact1: the average age of CEO nowadays is 57
Fact2: the average age of those executives are 20 years smaller than age of today’s CEO.
Conclusion: CEO tends to older now.
Weaken: retirement law requires corporate executives work until 60, or the TMTs cannot obtain the whole pension they got 20 years ago.
88 82’’

Premise: value of a product depends on the ratio of its quality to price.
Argument: the higher value, the better the competitive position.

90 60’’ AWA
Argument: dedicating the Cookville factory entirely to drill bit production and shifting all other machine part production to our other factories will help us to attain that larger goal.
Points:
1. To begin with, the manager commits a mistake about a simple principle in economics: the economy of scale. Though Cookville makes drill bits efficiently in recent scale, no evidence is provided by the author that Cookville will still produce on an efficient point when added more apparatus and workers…
2. Furthermore, though Cookville now produces drill in a higher productivity, in no cases can this mere fact be sited as an evidence that turning Cookville to a professional drill factory from a diversified factory will deduce the production cost and increase the whole efficiency of corporation. For example, the cut mechanics in Cookville might not collaborate with their colleagues in another factory, or they might ask for a salary increased to mitigate the loss in their rearrangement. All of above might increase the management costs and make shifting production unacceptable.
3. Last but not least. A causal relationship false exists in the argument. The author imprudently predict that to lower the production costs can necessarily assure the corporation to achieve a ‘larger goal’. In his deduction, he neglects some factors which need to be addressed if the corporation really want to obscure its ‘large goal’. For example, to sale out the products, Cookville should have a precise marketing plan and they …
