In the question below, a premise is provided. Choose the option that represents the statements that most strengthen the argument. Premise: A comprehensive analysis of urban development over the last three decades has found that cities that implement "Green Infrastructure" (such as urban forests and permeable pavements) see a 15 percent reduction in annual flood-related repair costs compared to cities that rely solely on traditional concrete drainage. The report, published by a consortium of environmental engineers and urban planners, suggests that natural solutions are more resilient than man-made ones. This finding is particularly significant at a time when many growing metropolises are debating whether to invest in expensive underground tunnels or cheaper, nature-based surfaces. Which of the following, if true, STRENGTHENS the argument? 1. The study found that the cooling effect of urban forests significantly reduces the energy costs of nearby residential buildings during summer months. 2. The report demonstrated that Green Infrastructure remains effective even in regions with very high population density, where critics previously claimed it would fail. 3. The research observed that cities adopting these natural solutions experienced fewer long-term structural cracks in their primary road networks during extreme weather shifts.
