Analyzing levels of proportional representation of American Indians in state and local
government jobs is important for several reasons. First, the basic idea underlying the theory of
representative bureaucracy is that the demographic composition of bureaucracy should mirror
the demographic composition of the general public. This is because in addition to its symbolic
value, increased access to managerial position may lead to greater responsiveness on the part
of policy makers to the policy interests of traditionally disadvantaged groups such as American
Indians. Second, the focus on higher level jobs in bureaucracies (as opposed to non-managerial
positions) is especially important because managerial positions represent a major source of
economic progress for members of traditionally disadvantaged groups, as these jobs confer
good salaries, benefits, status, security, and mobility. Third, it is important to know if there has
been growth in the American Indian share of more desirable public sector positions over the
last two decades. For instance, Peterson and Duncan argue that the population and power of
American Indians have been growing in certain states. Peterson and Duncan also suggest that
this growth may reflect the possibility that American Indian population are becoming
more active in nontraditional areas of politics, assimilating into mainstream culture, and
securing with greater frequency leadership positions in non-tribal government.

The passage suggests which of the following regarding “access to managerial positions” for
disadvantaged groups?
A. This access is only significant when the percentage of disadvantaged group members in
managerial positions mirrors the percent of that group in the general public.  
B. This access is largely the result of policy decisions made response to interest of those groups.  
C. This access has meaning apart from any policy benefits it confer on those groups.  
D. This access often creates increased access to non-managerial position for those groups.  
E. The extent of this access tends to be similar across different disadvantaged groups.


答案给的是C，不明白。
这道题定位应该是：This is because in addition to its symbolic
value, increased access to managerial position may lead to greater responsiveness on the part
of policy makers to the policy interests of traditionally disadvantaged groups such as American
Indians.我觉的这句话的意思是：access to managerial position的增加会使政策制定者更加关注弱势群体的政策利益。
C里面，apart from不是除了吗？那C选项的意思是This access除了任何对弱势群体有利的政策之外，是有意义的。也就是说，This access对于对弱势群体有利的政策来说没有意义吧。不是和原文的意思相反吗？或者我哪里理解的不对？
