In recent years, urban gardening has gained popularity

Solution

The passage makes the case that urban gardening is not just about food, but also fulfils a deeper emotional or psychological need to reconnect with nature. Statement I supports this by providing evidence of psychological benefits such as reduced stress and improved life satisfaction. This directly strengthens the argument. Statement II adds context and supports the popularity and accessibility of urban gardening, reinforcing its relevance in city life. While it does not directly address the emotional aspect, it strengthens the idea that this trend is real and growing. Statement III points out that gardening is usually associated with rural areas, which may imply that it’s unusual in urban areas. However, this doesn’t strengthen the idea that urban gardening meets a psychological need. It may actually weaken it by suggesting impracticality. Hence, Statements I and II strengthen the argument.
