以下是引用chichi在2003-9-3 9:51:00的发言: About braveMBA's explain, you want to say a high frequency of infections don't mean the body's vulnerablility to infection, don't you ? It seems a good explain.
其实E中的high frequency of infections 已经是the body is vulnerablility to infection了。E想要表达的是可能(CAN)有别的原因造成了the body is vulnerablility to infection而不是from any disorder of the immune system. 而disorder of the immune system同结论中的mental states influence 没有任何关系,不在一个集合里。所以,并没有削弱结论。我觉得MINDFREE解释得很对,If E said that the disorder of immune system in this group of people stems from higher level of exposure, it is the right answer. |
