题目解答
答案
[答案]:B
解析
本题主要考查对发达国家人口结构特点的理解，特别是人口老龄化这一社会现象。解题关键在于明确发达国家中老年人口数量与年轻人数量的对比，需结合生育率下降、医疗条件改善等背景知识。
选项分析
A. are better at business
错误。老年人在商业能力上并无显著优势，此选项缺乏事实依据。
B. are greater in number
正确。发达国家因生育率下降和医疗进步，老年人口比例持续上升，数量超过年轻人。
C. have healthier lifestyles
错误。虽然老年人可能更注重健康，但“健康生活方式”与实际行为（如运动量）未必直接相关，且题目强调“数量对比”。
D. have more job opportunities
错误。老年人通常已退休，就业率低于年轻人，此选项与现实矛盾。
