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

个人观点：

E说人们一般加入为了自己组织成员利益而服务的组织（我翻译的不好lol）

那么题干中说了现实中最大的几个老年社团组织的成员都是中产阶级的人，把这个和E结合起来，就能知道因为中产人们加入这些组织（这些组织中产多），所以这些组织是代表中产老年人的利益的，确实人们应该质疑你们这些社团到底对经纪上有困难的老人有没有帮助

解释的太烂，不好意思……
