feifei-130题(C)(D)are the same.

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 as shown that they 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 lack of magnanimity is the cause of most serious illnesses.
(B) magnanimous behavior can be regulated by the presence of absence of certain chemicals in the brain.
(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

(B) 应该是：lack of magnanimity is the cause of most serious illnesses

(B) magnanimous behavior can be regulated by the presence of absence of certain chemicals in the brain.
(C) magnanimous behavior can be regulated by the presence or absence of certain chemicals in the brain.
只有红色字体不同，是否按2楼的改正？

另外，Recent research as shown that they activity of these white blood cells is stimulated by beneficial chemicals produced by the brain as a result of magnanimous behavior.

they是否错，应为the？

Reference:

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

magnanimous behavior＝》 beneficial chemicals produced by the brain＝》 they activity of these white blood cells＝》fight infection

So, the correct answer is D.

A is out of scope. Because unselfish motives is 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 of B and C fail to convince us that magnanimous behavior can be regulated by the presence of absence of certain chemicals in the brain.

E is out of scope. The argument fails to establish the casual relationship between the number of white blood and the rate of magnanimous behavior.

对画线部分有另外的理解，原文应该存在下面推理：

1、magnanimous behavior＝》beneficial chemicals produced by the brain=》they activity of these white blood cells；

2、The bone marrow and spleen－》white blood cells－》fight infection

其中，原文一样没有提及they activity of these white blood cells与fight infection的关系，并不能证明stimulate activity导致更加fight infection，这里我们只能根据常识判断。当然，这里这个选项是best。

我认为应该这样解释：

1、doing good deeds＝》benefits one’s immune system

2、magnanimous behavior 《＝》good deeds（良好行为）

所以推出E。

Hi,

請教一下大家,答案(D)的interests是不是指"好處,益處",不是指"興趣"?

謝謝噜...^_^

D

貌似 这个题 答案是 D，而非c或e。e有点极端，c把两者关系搞颠倒了。
d的意思是说，做出好的行为是对自己有利的。因为文章说了，好的行为可以增加免疫，这当然是对自己有益

这是一道Must Be True题
Conclusion：
第一句话：mind和immune是有联系的，科学家发现行善有益于免疫系统
Premise：
1) The bone marrow and spleen produced by the brain --> white blood cells -->fight infection
2) magnanimous behavior 慷慨行为--> beneficial chemicals produced by the brain --> the activity of these white blood cells --> fight infection

选项A 带入一个新概念，错
选项B和C 都偷换了原文概念 多了个absence,错
选项E 中最主要的问题是radically 这个程度副词在原文中没有提到。(无论在LAST Logical Reasoning Bible, GMAT Logical Reasoning Bible 还是陈向东 GRE，GMART，LSAT逻辑 书中都提到，在Must Be True题目中的程度副词一定要能在文中找到对应)
其实选项D，慷慨是对自身有利的，也正是紧扣了原文作者结论：doing good deeds benefits one’s immune system
