240．Though sucking zinc lozenges has been promoted as a treatment for the common cold, research has revealed no consistent effect. Recently, however, a zinc gel applied nasally has been shown to greatly reduce the duration of colds. Since the gel contains zinc in the same form and concentration as the lozenges, the greater effectiveness of the gel must be due to the fact that cold viruses tend to concentrate in the nose, not the mouse.

In order to evaluate the argument, it would be most helpful to determine which of the following?

A. Whether there are remedies that do not contain zinc but that, when taken orally, can reduce the duration of colds

B. Whether either the zinc gel or the lozenges contain ingredients that have an impact on the activity of the zinc

答案是B文章里说了the gel contains zinc in the same form and concentration as the lozenges为什么B还要问呢？而且A正好回答the fact that cold viruses tend to concentrate in the nose, not the mouse

另一题

1．Executive: The process of submitting bids for architectural contracts should be restructed because when a contractor bids for a contract is acutely aware that other contractors will be submitting bids for the same contract. Therefore, the amount of a bid is not an accurate gauge of how much a contract is actually worth.

Which of the following is an assumption made in drawing the conclusion above?

A. Contractors often charge outrageous amounts for even simple architectural projects.

B. Some architectural contractors base the amount of their bids on factors other than the amount of money necessary to complete the contract.

答案是B 原文结论说the amount of a bid is not an accurate gauge of how much a contract is actually worth意思是说the amount of a bid 不能用来衡量worth

而B说不能用money 衡量amounts 这不是和文章说反拉吗？

另外A错的解释是原文实际意思是contractors undersell 这个bits 到底是怎么回事呢？不是价格最高的获得contract吗？不明白请指教 谢谢

240是归纳题,就是说文中所说的内容是回答下面哪个问题的.文章总体是告诉我们zinc gel比zinc lozenge 更有效是因为the fact that cold viruses tend to concentrate in the nose, not the mouse,所以它

不能回答A的问题:不含zinc的药是否会对感冒有效?

但可以回答B:是否是因为zinc gel含有某种特殊的成分对感冒有效? 回答是;不是

我觉得你理解是对的,但是题目没有搞清楚

另一题:

1.题目的主题意思:

the process of bid 应该reconstruct 因为the amount of a bid is not an accurate gauge of how much a contract is actually worth.

并且告诉你一个条件是一个bid 会受其他contractor的影响.

答案C,取非,排除他因虚弱, Some architectural contractors do not base the amount of their bids on factors other than the amount of money necessary to complete the contract.一些contrator不是因为其他原因来bid的,就是根据实际的需要来bid的,说明contractor带来的影响是好的,根据necessary bid,那出来的价格肯定是accurate的.虚弱原文的结论.

A取非,不能构成削弱,开不开outragous price和accurate不能构成直接

的联系,应该属于无关选项.这个应该属于一个支持选项,不是assumption.

文章说不应该base on the amount,推出 B说有人base on the amount 是不是这样？

但是如果对A取非不就是说amounts可以作为评判标准吗？不明白？答案说contactors 没有charge outrageous 而是undersell 还不明白！

我想你是掉进base on the amount的字面意思里了，其实它的含义就是说是根据本身的价值来定价。这题的关键是精确性不是定价的方式，你再仔细看看题

这题逻辑关系抽象一下就是这样：

一个东西要改，因为一个bid受别人的影响，bid不精确。

加强就是：别人的影响是不精确的。

削弱：别人的影响是精确的。

选项A。支持选项，因为别人开出天价是不精确的，那么别人开除很低的价格也会影响到bid最终价的精确性。

可能别人喜欢中午出价高，晚上出价低，这样的人加入bid，肯定影响bid的精确性啦。嘻嘻，就是说支持选现只要沾边就行，不必很充分的正确答案；assumption。只要不是按照neccessary 来定价的方式都是不精确的，而答案正好告诉你别人是按照除了necessary的其他所有方式来定价的。非常完美.
