逻辑姊妹篇http://forum.chasedream.com/GMAT_CR/thread-580862-1-1.html

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.

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.【40s】一个州决定征收再其管辖权内商品的百分之七的消费税。--》但是这个政策对城府的财政税收收入有反作用--》收入越少的人,其缴税的比例占其收入越多。
premise:收入越少的人,其用来消费的收入比例越高。
2.【20s】调查发现,公司CEO的平均年龄是57,但是20年前的这些公司CEO的平均年龄要年轻8岁,--》现在公司CEO的年龄成变大的趋势。
Weaken:这些20年前就成立的公司的CEO和现在的CEO是同一个人。(好抽象,,想不出,。。)
3。【57s】声波探测是一个技术结合空间声波望远镜来探测物体。因为塔结合了声波望远镜,需要详细的定位和复杂的电脑系统的支持。所以说再卫星上的它结合着声波望远镜是各种先进科技的结合。
Infer:声波望远镜,。。设备都是科技???
4.【25s】决定一个物品的价值是它的质量和价格。-->如果一个物品的质量越好,它越具有竞争力.-->可以既可以通过降低价格也可以通过提高质量来吸引顾客.
support:举个具体的例子,降低价格了,或者是提高质量了,商品的销量增加了~
