20. B. The key step is the understand about the question, which asking:
Which one of the following principles, if established (would determine) that demolishing the houses was the right decision (or instead would determine) that the proposal advocated by the opponents of demolition should have been adopted?

That is, the principles would determine A or B, whatever between this two.

15. D  questioning the judgment of the proposal’s backers by citing past cases in which they had advocated programs that have proved ineffective
我想这个选项是错在这里，题干中并没有说这些backer曾在过去支持一项类似的提案
题干的隐含的premise是 the proposal would bring a higher level of personal savings，economist引用过去一个失败的例子—类似的提案并没有增加储蓄。所以选A

20. 我选的是A,实在想不出来为什么选B,而且觉得选B不甚合理。
按照B的原则，demolishing the houses 和rehabilitate the houses是两种方法，最后采取了前者，因为demolishing the houses如果unsatisfactory没有排除rehabilitate the houses 的可能。但推到了的房子还怎么可能rehabilitate, 题干的结果与这个原则正好相反（还是我理解反了？）

这句话的意思我理解是：两个提案中只有一个排除了这种可能性--first令人不满意，还可尝试second.就是说其中一个提案如果saitsfactory，就不可能trying the other approach

请帮忙看看；
LAST第九套第一部分：
15）答案选A，可我觉得D更合适。
20）这题我虽然选对了，但对答案的意思没理解清楚，特别是答案中间那句“and only one of them would proclude the possibility of trying the other approach if the first proves unsatisfactory"

Louisa_xy:
         thanks lot!
你的题目：

1）我是说你的题目没写完“the all of our ”后面是什么？
2）文中提到的都是“NEW”，没有涉及其他如“old or undiscovered"，你不能自主的将其范围扩大，infer只能就文中所给的范围、内容INFER。
3） ‘homelessness is a serious social problem figures’在此文中相当与一个开场白，结论无论是“ people are homeless because of a lack of housing is wrong.”or“people are homeless because of a lack of housing is right”，都与这句话没有直接的关系。
而E）表示是的是这句话是结论成立的必要条件（当然不是）
  C）表示的是，这句话无论对结论或反结论都是一致的，（当然是的，因为这句话说的是一个客观事实，无论推论如何都不会影响它的成立）
举个简单的例子：城市的人口增长了（客观事实），一些认为是由于大量人口迁入造成的（A推论），但因为没有相关的移民记录，所以这中推论一定是错误的。（反对A另一个推论B）。——W无论A或B成立都不可能改变事实即人口增长。

Louisa_xy

1) A和D这两个选项都是完整的，我不明白这两个孰对孰错
2）any therapeutic agent is marketed不也包括new therapeutic agents么？
3）Homelessness is a serious social problem 我认为是双方都承认的事实，是这个argument的premise.

你的问题：

当火山熔岩凝固的时候，它的磁场方向与地球的磁场方向一致。在过去几百万年的时间里，不同火山的熔岩磁场方向有显著的差别，因此必然是地球的磁场方向随时间发生的改变。由于几千年内形成的熔岩磁场方向相似，一定是地球的磁场方向每几十万年改变一次。
24．Assumption: at least the direction of magnetization of some lava has not change since it formed
25. 熔岩表面和中心的磁场方向不一致, 说明在两个星期里地球磁场方向改变了

redli

大家也帮我看看LAST第16套第二个SECTION的24-25（一个大题），我没绕清楚它的意思，特别是关于“similar\different"方面。

redli

1）你好象没写完整。
2）是否选B，文中强调的是‘new therapeutic agent”而非ANY所以不选（A）
   “excessively”我同意你的看法。
3） “Homelessness is a serious social problem”，无论“accepting the conclusion or with denying ”结论，都不影响它的成立，所以选C，而E则强调它是结论成立的条件，显然不对。

some questions:

1. Public reports by national commissions, governor’s conference, and leadership groups have stressed the great need for better understanding of international affairs by the citizenry. If the country is to remain a leading nation in an era of international competitiveness, the need is undesirable. If there is such a need for the citizenry to have a better understanding international affairs, the all of our

If all of the statements in the passage are true, which one the following must also be true?

A)If the country is to remain a leading nation in an era of international competitiveness, then new teachers must be prepared to teach their subject matter with an international orientation.
D)If the country is to remain a leading nation in an era of international competitiveness, then there is no need for the citizenry to have a better understanding international affairs

答案是A. 我选D
题干中有If the country is to remain a leading nation in an era of international competitiveness, the need is undesirable.怎么推出then new teachers must be prepared to teach their subject matter with an international orientation呢？
-------------------------------------------------------------------------------

2.The United States FDA regulates the introduction of new therapeutic agents into the marketplace. Consequently, it plays a critical role in improving health care in the United States. While it is those in the academic and government research communities who engaged in the long process of initial discovery and clinical testing of new therapeutic agents, it’s the FDA’s role and responsibility to facilitate the transfer of new discoveries from the laboratory to the marketplace. Only after the transfer can important new therapies help patients.

Which one the following statements can be inferred from the passage？
A)The FDA is responsible for ensuring that any therapeutic agent is marketed is then regulated
B)Before new therapeutic agents reach the marketplace they do not help patients
C)The research community is responsible for the excessively long testing period for new drugs, not the FDA
D)The FDA should work more closely with researchers to ensure that the quality of therapeutic agents is maintained

A和C不对，是因为A里的any和B里的excessively么？
------------------------------------------------------------------------------
3.Politician: Homelessness is a serious social problem, but further government spending to provide low-income housing is not the cure for homelessness. The most cursory glance at the real-estate section of any major newspaper is enough to show that there is no lack of housing units available to rent. So the frequent claim that people are homeless because of a lack of housing is wrong.

That homelessness is a serious social problem figures in the argument in which one of the following ways?
A)It suggests an alternative perspective to the one adopted in the argument
B)It sets out a problem the argument is designed to resolve
C)It is compatible either with accepting the conclusion or with denying it
D)It summarizes a position the argument as a whole is directed toward discrediting
E)It is required in order to establish the conclusion
C是答案，E为什么不对呢？

thanks!
