A.I. Explanation:

Option 1: "To increase the number of volunteers in urban areas"

Explanation: While the text mentions that participants can volunteer for tree planting events, the primary goal of the GreenWay Initiative is not focused on increasing volunteer numbers. This option misinterprets the main objective, which is about environmental improvement rather than volunteer recruitment.

Option 2: "To improve air quality and reduce urban heat"

Explanation: This option accurately reflects the main goal of the GreenWay Initiative as stated in the text. The initiative aims to transform urban spaces by focusing on reducing urban heat and improving air quality, which aligns with the overall theme of creating sustainable environments.

Option 3: "To provide financial support to environmental NGOs"

Explanation: The text does not indicate that the primary goal of the GreenWay Initiative is to provide financial support to environmental NGOs. Instead, it highlights collaboration with these organizations to achieve environmental goals, making this option misleading.

Option 4: "To promote the construction of new urban buildings"

Explanation: This option contradicts the text, which emphasizes transforming urban spaces into sustainable environments rather than promoting new construction. The focus is on planting trees and creating green roofs, not on building new structures.
