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

Reference:

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

magnanimous behaviorà beneficial chemicals produced by the brainà they activity of these white blood cellsà 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.

I think the answer should be E !! lets discuss it !!!(I searched that there is no discussion about E)

I would choose D

E is not right b/c 
            the number of white blood cells will increase
                    radically
                if behavior is consistently magnanimous.

we only know from the context that the number of white blood cells will increase, but it does not say radically.

Hence, E is not correct.

还是没明白，D.       magnanimity is beneficial to one’s own interests 又说明了什么呢？

哦谢谢~~~~

那就是原推理说M....&*^%$#...对**好，答案就直接说M好，这是什么方法呢？

姐姐 您说什么呢...我晕

没看明白

having a good immune system is to everyone's own interest     ？ why

我觉得原文和选项说的两码事啊

interest在哪儿？

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.

here,we can make a conclusion that can be described below:

magnanimous behavior--------produce chemcials-----stimulate the activity of the white blood cell

So we found that magnanimous behavior will stimulate the activity of the cells not the number .

Hence ,E is out of scope.Nothing regarding the number of white blood cells was discussed in the argument.

In choice D ,because magnanimous behavior will stimulate the activity of the cells ,magnanimous behavior will do us good  and that is all about choice D.

So D is the best answer definitely
