    A.which
    B.there
    C.where
    D.that

    答案：C
    解析：
    语法结构题。根据句子结构判断，这是一个定语从句，先行词为countries，故排除[B]there．该词不引导从句；其次可以排除[D]that，该词不能用于非限定性定语从句；而从句不缺成分，故只能使用关系副词[C]where，而不能使用关系代词[A]which。故答案为[c]。

    A.Compared wiLh

    答案：C
    解析：
    逻辑关系题。[A]Compared with与……相比；[B]Because of因为；[C]According to根据，按照；[D]In spite of尽管。首先该句提出老年人口的一组数据，并没有与谁作对比，故[A）项可以排除。而该句上下文没有体现出因果关系，故选项[B]也排除。而[D）项的逻辑为让步．填人的话上下文必须有相反信息，而此处没有，故错误。故答案为[C]。

    答案：A
