Social scientists are underrepresented on the
advisory councils of the National Institutes of Health (NIH). Since these councils advise NIH directors and recommend policy, the underrepresentation of social scientists results in a relative lack of NIH financial support for research in the social sciences.

If the statements above are correct, they most strongly support which of the following?

(A)          A significant increase in the size of NIH advisory councils would be required in order to increase the representation of social scientists on these councils.

(B)          A significant increase in the representation of social scientists on NIH advisory councils would result in an increase in NIH funding for social science research.

(C)         A significant increase in funding for social science research would result in improved policy recommendations to NIH directors.

(D)         A significant increase in funding for the training of social scientists would result in an increase in the number of social scientists on NIH advisory councils.

(E)          A significant increase in the representation
   of social scientists on NIH advisory      - councils would have to precede any increase in the number of NIH directors who are social scientists.

阅读,对题目含义的理解. 如果把underrepresented 作为原因A , 那么lack financial support 作为B 结果.

原文A→B, 它的等价命题应该是逆否命题,也就是-B→-A
        . ,但是答案B 好像是-A→-B ,  这不是等价命题啊, 如何解释呢?

The problem states that because there are not enough social scientists on the councils, so there is not enough fund for their field.

B says, if you increase the number of social scientists on the councils, then there will be enough fund for their field.

Isn't it obvious to you now?

just try to understand the problem by using your common sense.

I am not good at sorting out the logic realtions, but I believe that for most of the GMAT CR questions, if you understand the meaning, you will get it.

没有社会科学家－－－－社会科学研究没有钱

B：有社会科学家－－－－就有钱

这题是support题

不是must be true

原题本身没有必要性：即有钱－－－就有社会学家；所以逆否命题本身没有成立的基础，也不适用于support题

另外，这样死套公式不太可取，还是要培养自己对题目和问法的感觉
