The fact that several of the largest senior citizensâ€™ organizations are constituted almost exclusively of middle-class elderly people has led critics to question the seriousness of those organizationsâ€™ 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) People usually join organizations whose purpose is to further the economic, political, or social interests of their members.
Please help me understand the argument and the question stem of this CR.
