During excavations for a highway, workers just uncovered a hoard of over 30,000 eighteenth-century gold coins. These coins, most in superb condition, are of a type that has long been quite rare and correspondingly highly valued. Several coins of the same date and type recently sold at auction for over $5,000 each, despite being in poor condition. Clearly, therefore, in today’s market, this hoard, if sold, is bound to bring in at least $150,000,000.
Which of the following is an assumption on which the argument depends?
(A) The workers who uncovered the coins did not take for themselves a significant number of coins before reporting their find.
(B) The hoard of coins would not bring in more if broken down into small parcels to be sold individually than if sold as a single quantity.
(C) The appearance on the market of thousands of additional coins of this type will not significantly affect the status of these coins as rarities.
(D) It is not possible to determine whether the hoard of coins was buried by people who were then its legal owners.
(E) Whoever might sell the coins would be sufficiently knowledgeable about such sales to secure the highest possible price for the coins.

Sales of Paradoze, a nonprescription sleeping pill, declined throughout the six months in which a certain television advertisement was used to promote the product. Yet the makers of Paradoze consider the television advertisement to have been very effective.
Which of the following, if true, most helps to resolve the apparent discrepancy?
(A) The makers of Paradoze had previously used television advertising to promote nonprescription products.
(B) On average, only one out of four advertisements for a nonprescription drug is judged effective by the drug's manufacturer.
(C) During the six months in question, Paradoze's share of a shrinking market for nonprescription sleeping pills increased.
(D) Paradoze was the only nonprescription sleeping pill being promoted through television advertisements during the six months in question.
(E) Paradoze's share of the market for nonprescription sleeping pills has always been small in comparison with that of its largest competitor.

1、同款硬币因为稀有所以市场售价每个a元，因此挖出的这堆硬币x个能卖ax元。
问assumption
思考：因果论证，思考搭桥或排除他因削弱

A：发现硬币的工人在上报前并没有私吞大量硬币。已经报告30000个，私吞与否与这个数量没有关系了。
B：碎片不会比整块更值钱。取非，如果更值钱，那售卖金额应该更大于1.5亿，结论更成立了。
C：这堆硬币不会改变这款硬币稀少的情况。正确，取非，如果这款硬币变得不再稀有，则售价就会降低，总价不可能这么多。
D：不可能判断这堆硬币之前是属于谁的。售卖金额与谁拥有无关。
E：卖硬币的人能卖最高价。不需要最高价。

选C

2、现象：P销量下降，原因：广告很有效。
问explain
思考：果因论证，果推反因，思考他因导致这个结果，不是广告无效导致销量下降，而是其他原因导致销量下降

A：之前也用过电视广告来促销非处方药。无关。
B；只有四分之一的广告有效。反驳前提。
C：市场在缩小，并且P的市场份额还上升了。正确，说明P销量下降是由于市场整体在缩水。
D：P是唯一一个在那个时期用电视广告的非处方安眠药。无关。
E：P的市场份额一直很小。无关。

文章先是说了一个事实：挖到了3万枚金币。目前对这样的甚至质量比挖到的差的金币市场价格在5000美元一枚。作者预测，这3万枚金币可以卖150,000,000美元。
作者基于的假设是：这三万金币涌入市场，不会影响它单个的价值。
当供过于求的时候，原本的价值就会受到波动，所以现实中很可能之前难求的金币突然大量涌入市场后会影响它现有的价值。

C
P这种药在近6个月内的销量下降，但是P的生产者却说广告效应有积极的作用。
市场份额增加了，是广告带来的其他功效，所以也算广告有效。
