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?
