linlin315

做了7套lsat竟然越错越多！所以停下来总结做过的每一道题！竟然发现有很多题说不上理由！不知对在那里也不知错在哪里！！我哭！只好向大家求援！希望大家不要嫌我烦！！
不哭了！写题！！
第7套sectionIVQuestions 5-6
The government provides insurance for individuals? band deposits, but requires the banks to pay the premiums for the insurance. Since it is depositors who primarily benefit from the security this insurance provides, the government should take steps to ensure that depositors who want this security bear the cost of it and thus should make depositors pay the premiums for insuring their own accounts.

5. Which one of the following principles, if established, would do most to justify drawing the conclusion of the argument on the basis of the reasons offered in its support?

(A) The people who stand to benefit from an economic service should always be made to bear the costs of that service.

(B) Any rational system of insurance must base the size of premiums on the degree of risk involved.

(C) Government-backed security for investors, such as bank depositors, should be provided only when it does not reduce incentives for investors to make responsible investments.

(D) The choice of not accepting and offered service should always be available, even if there is no charge for the service.

(E) The government should avoid any actions that might alter the behavior of corporations and individuals in the market.
答案是A
这道题我的问题：
1、相了半天没看出是什么题型！justify是证明。。。是正确的！是加强题吗？
2、只是感觉上觉得这道题选A但是细揪一下是如何推出来的呢？
6. Which of the following is assumed by the argument?

(A) Banks are not insured by the government against default on the loans the banks make.

(B) Private insurance companies do not have the resources to provide banks or individual with deposit insurance.

(C) Banks do not always cover the cost of the deposit-insurance premiums by paying depositors lower interest rates on insured deposits than the banks would on uninsured deposits.

(D) The government limits the insurance protection it provides by insuring accounts up to a certain legally defined amount only.

(E) The government does not allow banks to offer some kinds of accounts in which deposits are not insured.
答案是E
这道题我的问题是：
（1）、假设的题型大家都是怎么做的啊？我满脑子的雾水一点思路都没有！
（2）、这道题为什么会选E呢！！

8. George: Some scientists say that global warming will occur because people are releasing large amounts of carbon dioxide into the atmosphere by burning trees and fossil fuels. We can see, though, that the predicted warming is occurring already. In the middle of last winter, we had a month of springlike weather in our area, and this fall, because of unusually mild temperatures, the leaves on our town抯 trees were three weeks late in turning color.

Which one of the following would it be most relevant to investigate in evaluating the conclusion of George抯 argument?

(A) whether carbon dioxide is the only cause of global warming

(B) when leaves on the trees in the town usually change color

(C) what proportion of global emissions of carbon dioxide is due to the burning of trees by humans

(D) whether air pollution is causing some trees in the are to lose their leaves

(E) whether unusually warm weather is occurring elsewhere on the globe more frequently than before
答案是B
这道题我也选B了。但是有个疑问：评价题的做法不是对于选项答yes or no将会对文章分别起到加强和削弱的作用吗？那么对B的回答是如何起到加强和削弱的作用的呢？？
真的很多！也实在是不好意思！不过性命忧关，大家多帮帮忙了！！

第5题问的是假设，不是加强(on the basis of )

since it is depositors who primarily benefit from the security this insurance provides, the government should take steps to ensure that depositors who want this security bear the cost of it and thus should make depositors pay the premiums for insuring their own accounts.

因为depositor benefit, 所以government should make them pay
假设：谁受益，谁付出

mindfree

我认为6题答案错了,应该是C.

思路很清晰,arguer认为不应该是bank pay insurance premium,而是应由depositors pay. assumption: banks have been paying the premium. C的意思是: bank没有通过降低利率来转嫁cost of premium给depositor, 既确实是bank在pay. 取非原结论不成立.

E为无关选项

我对第8题anchoret的讲解不太理解. 原文并没有讲是和去年相比今年晚.我读完题的感觉是:由于mild weather in the fall in this town-->global warming has come already. 既由局部现象推出整体(local weather --> global). 请各位仔细讲解. 同时请linlin确认答案.

谢谢.

mindfree

关于6T, C选项的意思是: 银行并没有通过降低付给存款人利息的方式来cover premium costs. 对其取非, 既银行always通过降低利率来cover costs -->实际上depositors一直是在cover premium costs, 因为他们得到的利息相比没有insurance的情况要低. Do not cover the cost不意味亏损.

我认为你曾经选C是对的. E是无关选项, "但如果对e取反，即“银行允许未保险的储蓄存在”，那么政府就不该让银行付保险费，反对了原文的结论。" 原文就是要政府设法不要让银行付保险费, 怎么是反对了原文的结论?

mindfree

关于8T, B选项结合了leaves turning color, 即和原文有一定的联系. 但是我无法正推此答案. 原文说时间晚了三周, 没有指和去年相比, 应该是general的说法,既比一般的时间晚. 如果一般turning color的时间是9月初, 或是一般为10月底,对evaluate有什么用处?

我的答案是E, 如果其它地区的气候也有类似的变化,说明the weather chage in this town is representative. 否则说明此变化无代表性, 不能说明global warming is coming.
