og17 粉色verbal分册 153题
In setting environmental standards for industry and others to meet, it is inadvisable to require the best results that state-of-the-art technology can achieve. Current technology is able to detect and eliminate even extremely minute amounts of contaminants, but at a cost that is exorbitant relative to the improvement achieved. So it would be reasonable instead to set standards by taking into account all of the current and future risks involved.   

The argument given concerning the reasonable way to set standards presupposes that
A.industry currently meets the standards that have been set by environmental authorities
B.there are effective ways to take into account all of the relevant risks posed by allowing different levels of contaminants
C.the only contaminants worth measuring are generated by industry.
D.it is not costly to prevent large amounts of contaminants from entering the environment
E.minute amounts of some contaminants can be poisonous
这道题，完全不理解，尤其是为什么不选D，哪位大牛救救孩子！

这道题其实如果把题目意思理解了，做题反倒不难。这道题有两处意思比较容易弄混淆，需要仔细阅读。

In setting environmental standards for industry and others to meet, it is inadvisable to require the best results that state-of-the-art technology can achieve.
制定环保标准时，不应该采取最牛逼的技术能达到的结果。（就是检测灵敏度的要求）
Current technology is able to detect and eliminate even extremely minute amounts of contaminants, but at a cost that is exorbitant relative to the improvement achieved.
当前的技术能检测到很微量的污染，但是付出的成本太高。
So it would be reasonable instead to set standards by taking into account all of the current and future risks involved.   
因此，制定规则时应该考虑到当前和将来的风险。
最后一句的意思比较模糊，看似和前面两句没有半毛钱关系，但是risk是指的污染物的risk。也就是说根据污染物的risk高低，来决定是采用什么灵敏度级别的standard。
所以答案是presuppose我们知道怎样根据污染物的risk来做决定。

你说的选项D文中没有提到。

选B吧？

这道题如果理解了就会发现特别搞笑。

题目的意思很简单：  因为用最高要求来制定标准不行，因此就用考虑所有risk的方法来制定标准。

这个思路类似于：你妈让你每天吃胡萝卜，你跟你妈说胡萝卜不好blablalbal, 然后你妈就说那行吧，每天吃一个大蒜。
总结来说，就是因为A不好，所以B就是好的。

楼主觉得很奇怪，是因为这个逻辑本身就是错的。A好不好是A的事情，跟B无关。A不好，不代表B就是好的。B好不好我们要看B本身的情况。

所以回到题目本身，因为是assumption题，我们取非削弱：D选项: 没办法考虑所有risk.  因此最高要求是不行的，考虑risk也不行，削弱结论。

这种题型，GMAT还考过一些其他题，核心就是A跟B是无关，A好不好，跟B无关。而且GMAT考试的时候，最常见的考点是A不好，B其实也不好。

1. Advertisement: Clark brand-name parts are made for cars manufactured in this country. They satisfy all of our government automotive tests-the toughest such tests in the world. With foreign-made parts, you never know which might be reliable and which are cheap look-alikes that are poorly constructed and liable to cost you hundreds of dollars in repairs. Therefore, be smart and insist on brand-name parts by Clark for your car.

The argument requires the assumption that


parts that satisfy or government standards are not as poorly constructed as cheap foreign made parts


2. A theory is either true or false. Galileo's observations of Jupiter's satellites showed that the Ptolemaic theory of the motion of celestial bodies is false. Therefore, since the Copernican theory of planetary motion is inconsistent with the Ptolemaic account, Galileo's observations of Jupiter's satellites proved the truth of the Copernican theory.

The argument above is open to the objection that it makes the questionable assumption that

the Ptolemaic and Copernican theories, being inconsistent, cannot both be false



3. Cable-television spokesperson: Subscriptions to cable television are a bargain in comparison to "free" television. Remember that "free" television is not really free. It is consumers, in the end, who pay for the costly advertising that supports "free" television.

Which of the following, if true, is most damaging to the position of the cable-television spokesperson?

There is as much advertising on many cable television channels as there is on "free" television channels



4. Political advocacy groups have begun to use information services to disseminate information that is then accessed by the public via personal computer. Since many groups are thus able to bypass traditional news sources, whose reporting is selective, and to present their political views directly to the public, information services present a more balanced picture of the complexities of political issues than any traditional news source presents.

Which of the following is an assumption on which the argument above depends?

Information on political issues disseminated through information services does not come almost entirely from advocacy groups that share a single bias


还有一些就不贴了，反正都差不多
