标题: 请教大全-14-7,大全-14-12
Bank depositors in the United States are all financially
protected against bank failure because the government
insures all individuals' bank deposits. An economist argues that this insurance is partly responsible for the high rate of bank failures, since it removes from depositors any financial incentive to find out whether the bank that holds their money is secure against failure. If depositors were more selective, then banks would need to be secure in order to compete for depositors' money.

7. The economist's argument makes which of the follow-
ing assumptions?
(A) Bank failures are caused when big borrowers
default on loan repayments.
(B) A significant proportion of depositors maintain
accounts at several different banks.
(C) The more a depositor has to deposit, the more
careful he or she tends to be in selecting a
bank.
(D) The difference in the interest rates paid to deposi-
tors by different banks is not a significant
factor in bank failures.
(E) Potential depositors are able to determine which
banks are secure against failure.

答案：E，我觉得D也是假设，是属于假设中的排除他因，为什么不是答案呢？

12. Although aspirin has been proven to eliminate moder-
ate fever associated with some illnesses, many doctors
no longer routinely recommend its use for this purpose.
A moderate fever stimulates the activity of the body's
disease-fighting white blood cells and also inhibits the
growth of many strains of disease-causing bacteria.

If the statements above are true, which of the following
conclusions is most strongly supported by them?
(A) Aspirin, an effective painkiller, alleviates the pain
and discomfort of many illnesses.
(B) Aspirin can prolong a patient's illness by eliminat-
ing moderate fever helpful in fighting some
diseases.
(C) Aspirin inhibits the growth of white blood cells,
which are necessary for fighting some illnesses.
(D) The more white blood cells a patient's body
produces, the less severe the patient's illness
will be.
(E) The focus of modern medicine is on inhibiting the
growth of disease-causing bacteria within the
body.

答案：B，我觉得B，C都对。

谢谢。

1、D本身引入了新的信息，超出了题目给定的范畴，而且它的成立与否都不能支持或否定题目中的结论，因为文中是partly。

2、C说的是抑制了白细胞的生长，这与文中的说法不符，文中是讲，使白细胞未能被发烧所激活，而没说抑制了白细胞的生长。

完全同意Cranberry的意见.

1. CR阅读要仔细, 不能漏掉细节, 虽然partly只是个副词

2. CR阅读过程中要对概念和名词敏感. 不同的概念就是gap. 如果文中没有填补这个gap, 不能用自己的知识去填补.

以下是引用cranberry在2003-4-27 20:08:00的发言：
1、D本身引入了新的信息，超出了题目给定的范畴，而且它的成立与否都不能支持或否定题目中的结论，因为文中是partly。

如果原文没有说partly,那么D也是假设吗?

假设中的排除他因可以引入原文没有的新的信息.

如
Questions 15-16 are based on the following.
Roland: The alarming fact is that 90 percent of the
people in this country now report that they know
someone who is unemployed.

Sharon: But a normal, moderate level of unemployment
is 5 percent, with 1 out of 20 workers unem-
ployed. So at any given time if a person knows
approximately 50 workers, 1 or more will very
likely be unemployed.

问假设:
(B) unemployment is not normally concentrated in
geographically isolated segments of the population

B中不就引进了原文没有的信息了吗?B也是排除他因的假设.

答案：E，我觉得D也是假设，是属于假设中的排除他因，为什么不是答案呢？

原题说：储户选择银行，银行便不会失败。

D是加强，E是假设。原因：取非可得：
D 利息支出是银行失败的重要原因。只是削弱原题结论：给出银行失败的另一个理由，不能使原题结论不成立，故D只能算加强。
E 储户不知道银行是否失败，即不会选择。原题结论必错。E是必要条件。ASSUMPTION

答案：B，我觉得B，C都对。

C本身根据逻辑和题意是对的，但在这道题里是错误答案。原因：C削弱了"fever inhibits the growth"这一事实。而削弱事实在gmat中是不允许的。

第七题中,到底假设和加强怎么区分????

偶觉得：取非看结论是否成立。请指正。
