大全-Ⅲ-17 马上要考试了9.6

大全-Ⅲ-17.  The fact that several of the
largest senior citizens’ organizations are constituted almost exclusively of
middle-class elderly people has led critics to question the seriousness of
those organizations’ commitment to speaking out on behalf of the needs of
economically disadvantaged elderly people.

Which of the following generalizations, if
true, would help to substantiate the criticism implicit in the statement above?

(A) The
ideology of an organization tends reflect the traditional political climate of
its locale.

(B) The needs
of disadvantaged elderly people differ in some ways from those of other
disadvantaged groups within contemporary society.

(C) Organized
groups are better able to publicize their problems and seek redress than
individuals acting alone.

(D) Middle-class elderly people
are more likely to join organizations than are economically disadvantaged
elderly people.（E）

(E) People usually join
organizations whose purpose is to further the economic, political, or social
interests of their members.

到底是怎么一回事？

把E的逻辑顺着往下推就推出来critics的conclusion了。

快考试了就别做LSAT了吧。。。。。。
