Feifei logic 有多处 错误，主要是原文和选项的错，而且有部分解释根据原文和选项的错解释错了！

其实我很早就发现了，但是不知道从哪些资料查到！  但是我今天终于找到错处了，和正确的原题！

其实大家都知道Feifei logic 是从LSAT来的！我从逻辑大全那里找到了原题，找到错处！

这次希望逻辑的版主可以仔细更正！

绿色底纹那些是漏了，或者错了！（不包括绿色字体）

比如：
128. The public in the United States has in the past been conditioned to support a substantial defense budget by the threat of confrontation with the Eastern bloc. Now that that threat is dissolving, along with the Eastern bloc itself, it is doubtful whether the public can be persuaded to support an adequate defense budget.



Which one of the following indicates a weakness in the position expressed above?



A.It presupposes that public opinion can be manipulated indefinitely, without the public’s becoming aware of that manipulation.

B.It refers to past and present events that do not have a causal connection with public support of the budget.

C.It assumes as fact what it seeks to establish by reasoning.

D.It fails to give any reason for the judgment it reaches.

E.It hinges on the term “adequate”, the precise meaning of which requires reevaluation in the new context.

130. The mind and the immune system have been shown to be intimately linked, and scientists are consistently finding that doing good deeds benefits one’s immune system. The bone marrow and spleen, which produce the white blood cells needed to fight infection, are both connected by neural pathways to the brain. Recent research has shown that the activity of these white blood cells is stimulated by beneficial chemicals produced by the brain as a result of magnanimous behavior.



The statements above, if true, support the view that



A.good deeds must be based on unselfish motives.

B.lack of magnanimity is the cause of most serious illnesses.

C.magnanimous behavior can be regulated by the presence or absence of certain chemicals in the brain.

D.magnanimity is beneficial to one’s own interests

E.the number of white blood cells will increase radically if behavior is consistently magnanimous



Reference:

In my view, the reasoning in this argument is that:

magnanimous behaviorà beneficial chemicals produced by the brainàthe activity of these white blood cellsà fight infection

So, the correct answer is D.

A is out of scope, because unselfish motives are not mentioned in this argument.

B and C have the same mistake. From the above reasoning, it is clear that because of magnanimous behavior, some beneficial chemicals were produced by the brain. But the statement ofB and C fail toconvince us that magnanimous behavior can be regulated by the presence of absence of certain chemicals in the brain.


本题已经更正了原文，A，B的缺陷，因为该题是来自于：LSAT SECTION VI的4题

这里B,C的选项在Feifei logic是相同的，而且解释中的B，C解释还是一样的，看来解释的那个人太疏忽了，没有注意到B,C的错处。

131. To become an expert on a musical instrument, a person must practice. If people practice a musical instrument for three hours each day, they will eventually become expert on that instrument. Therefore, if a person is an expert on a musical instrument, that person must have practiced for at least three hours each day.



Which one of the following most accurately describes a flaw in the reasoning above?



A.The conclusion fails to take into account that people who practice for three hours every day might not yet have reached a degree of proficiency that everyone would consider expert.

B.The conclusion fails to take into account that practicing for less than three hours each day may be enough for some people to become experts.

C.The conclusion fails to take into account that if a person has not practiced for at least three hours a day, the person has not become an expert.

D.The conclusion fails to take into account that three consecutive hours of daily practice is not recommended by all music teachers.

The conclusion fails to take into account that few people have the spare time necessary to devote three hours daily to practice.

其实还有错处，我正在更正！  我更正完了，我就把它全部上传！

其实那个刚刚出的那个CHASEDREAM 2008 PREP V2.02的解释也是文字上的错误，这个我也在更正，希望我能尽快完成，尽快上传！
