Lecturer: Today we're discussing the impact of urban green spaces on mental health. A recent study conducted in Melbourne followed over 2,000 residents for five years. The researchers found that people living within 300 meters of a park or garden reported significantly lower levels of stress and anxiety. Interestingly, the size of the green space mattered less than its accessibility. Even small pocket parks had a positive effect if they were easy to reach on foot. However, the study also noted that the benefits were stronger for older adults, particularly those over 65, compared to younger participants. This suggests that urban planning should prioritize creating small, well-connected green areas, especially in neighborhoods with higher proportions of elderly residents.

A. Larger parks were more effective than smaller ones.

C. Only parks larger than 300 square meters provided benefits.
D. The benefits decreased when parks were too small.
