　　参考答案

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

　　magnanimous behavior beneficial chemicals produced by thebrain they activity of these white blood cells fight infection

　　So, the correct answer is D.

　　A is out of scope. Because unselfish motives is notmentioned in this argument.

　　B and C have the same mistake. From the above reasoning , itis clear that because of magnanimous behavior, some beneficial chemicals wereproduced by the brain. But the statement of B and C fail to convince us thatmagnanimous behavior can be regulated by the presence of absence of certainchemicals in the brain.

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