8-23 1. 55s 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? 有一个州对它管辖范围内买的东西征一个7%的税。结论：如果将这个税看成是收入的话，那就成了一个反比：收入越低，税越高。 说有个消费税，结论是越穷的人这个消费税对于穷人站的比例越高~ 假设：收上来的税要化更大的比例出去。 Answer: The amount of money citizens spend on products subject to the state tax tends to be equal across income levels. 收入高低不同的人，对于那些有附加税的产品的购买量是一样的！前提支持
2. 15s 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? 现在调查大多数CEO的平均年龄是57岁，而20年前的这些公司的调查结果要年轻8岁。结论：CEO正在变的年龄越来越大。 削弱：调查的都是成立了20年以上的大公司，CEO的年龄也就自然高些，样本不具有代表性。 Answer: The information is based only on companies that have been operating for at least 20 years.偷换概念
3. 38s 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? Radio interferometry 无线电干涉测量 radio telescopes 无线电望远镜 说 interf 这个技术咋咋咋复杂，在宇宙中，还要用啥紫外线，和这个那个反应。结论：interf这个东西是个复杂的技术工程。 推论：只要是requires ultraprecise timing, exact knowledge of the locations of the telescopes, and sophisticated computer programs.，那么就是a significant technological accomplishment. Answer: The location of an orbiting satellite relative to locations on Earth can be well enough known for interferometric purposes. 我想应该是题干里面提要了require exact knowledge of the locations of the telescopes ， 这个这个技术成功运用的先决条件，既然这个技术成功，那The location就要知道啦。 往前推，线索一致。
4. 26s 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? 产品的性价比是一个产品的质量和价格的比率。性价比越高，这个产品就越具有竞争优势。结论：通过提高质量或者降低价格，就能吸引顾客来买这个产品。 支持：一个调查发现，价格一样的某种产品，质量好的买的人更多。 Answer: Consumers’ perceptions of the quality of a product are based on the actual quality of the product.前提支持
AA：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.” drill bits 钻头 1. advanced and efficient不能光凭产量来决定，说不定C生产的东西质量都不好。 2. 不能全部都投到C上，说不定C生产10个已经是最大产量了。 3. shifting的成本很高的，根本不划算。
1.43s(每天看懂。。。) P:增加7%的tax。如果看做所得税，收入越低，税收越高 C:对政府所得税收入上，有相反的作用 Assumption：真的想不到。。。GAP到底在哪儿？ 2.18s P:current --average age of CEOs is 57; 20 years ago--average age is 8 years younger C:CEOs in general tend to be older now Weaken: point some differences between 20 years ago and now 3.48s（写不下去了。。。） P: Radio I需要很多步骤balabalabala... C: 一个成功的卫星和地球radio的I连接，是一个important technological accoplishment MBT: 如果能实现C中所说的连接，是需要很负责的步骤的 4.22s P=Plan：either improve the quality or decrease the price C=Goal: attract more customers from our competitors Strengthen: the competitors will not adapt the same strategy; OR the customers will not considerate other factors except price and quality when they make a choice; OR the customers will be alert to the price and quality change
