答案： I would definitely choose to provide community elderly services among the three options. The main reason is that Taiwan is facing a serious aging population problem, and many elderly people living alone lack daily care—some even struggle to prepare meals or clean their houses. This service can directly meet their urgent needs and bring warmth to their lives, which is more meaningful than simply holding a market or an art event. To make this service effective, we can design three core activities. First, organize a meal delivery team: volunteers will cook nutritious lunches at school and deliver them to elderly people who cannot move around easily. This ensures they have healthy food every day. Second, arrange regular cleaning sessions: students can help clean the elderly’s rooms on weekends, as dust and clutter are bad for their health. Third, set up a companionship program: volunteers can chat with the elderly, read newspapers for them, or help them make video calls with their children. These activities are designed to address the elderly’s physical and emotional needs, making the service comprehensive and heartwarming.。 略解：第一段明確選擇「提供社區老人服務」，以「台灣人口老化」「獨居老人缺乏照顧」為原因，突出服務的必要性；第二段設計「送餐」「清掃」「陪伴」三項具體活動，分別對應老人的飲食、健康、情感需求，理由充分且切合主題，文長超120詞，句構多樣（如從句、分詞短語），詞彙準確（aging population、nutritious lunches），符合評分要求。
