Some questions:

Brain scans of people exposed to certain neurotoxins reveal brain damage identical to that found in people suffering from Parkinson’s disease. This fact shows not only that these neurotoxins cause this type of brain damage, but also that the damage itself causes Parkinson’s disease. Thus brain scan can be used to determine who is likely to develop Parkinson’s disease.
The argument contains which one of the following reasoning error?
A)It fails to establish that other methods can be used to diagnose Parkinson’s disease are less accurate than brain scans
B)It overestimates the importance of early diagnosis in determining appropriate treatments for people who suffering from Parkinson’s disease
C)It mistakes a correlation between the type of brain damage described and Parkinson’s disease for a casual relation between the two
我选C,答案是B, 但是原文里并没有提到治疗Parkinson’s disease啊？

People who receive unsolicited advice from someone whose advantage would be served if that advice is taken should regard the proffered advice with skepticism unless there is good reason to think that their interests substantially coincide with those of the advice giver in the circumstance in question.

This principle, if accepted, would justify which one of the following judgments?
A)        After learning by chance that Harriet is looking for a secure investment for her retirement savings, Floyd writes to her recommending the R&M company as an especially secure investment. But since Floyd is the sole owner of R&M, Harriet should reject his advice out of hand and invest the savings elsewhere.
B)        While shopping for refrigerator, Ramon is approached by salesperson who, on the basis of her personal experience, warns him against the least expensive model. However, the salesperson’s commission increases with the price of the refrigerator sold, so Ramon should not reject the least expensive model on the salesperson’s advice alone.
答案是B, A 为什么不符合？

Thanks!

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!

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

many thanks to both of you!

How are you going with LAST now? I've got 2 section left.

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
