A.I. Explanation:

Option 1: "To increase the construction of high-rise buildings in cities"

Explanation: This option contradicts the main idea of the text, which focuses on promoting green spaces rather than high-rise buildings. The text highlights the need for more nature in urban environments, not more concrete structures.

Option 2: "To promote the integration of green spaces in urban areas"

Explanation: This option accurately reflects the primary goal of the 'Green Futures' initiative as stated in the text. The initiative aims to integrate parks, rooftop gardens, and vertical gardens into urban areas, which is clearly articulated in the text.

Option 3: "To encourage the use of electric vehicles in cities"

Explanation: This option is incorrect because the text does not mention electric vehicles at all. The focus is solely on increasing green spaces, which does not relate to vehicle usage.

Option 4: "To reduce the population in urban areas"

Explanation: This option is incorrect as it does not align with the text's message. The initiative aims to enhance urban living through green spaces, not to reduce the population.
