题目 17 范文：支持 A（运动影响更大）
I agree with Claire that regular exercise can play the larger role in many people’s mental health. Physical activity can improve mood, reduce stress, and create better sleep. These benefits support a person’s ability to handle work, study, and relationships. Exercise also gives individuals a practical action they can control, even when other parts of life are difficult. A daily walk with a friend, for example, provides both movement and social support. Paul is correct that genetics and environment matter, but people cannot easily change their genes, and changing an entire environment may take time. Exercise is not a cure for every condition, yet it is an accessible habit that can improve well-being and work well with professional care.
