A scientist studies a coastal marsh and makes a claim: "Building a seawall changed the marsh habitat by reducing the area of marsh plants." Evidence: - Marsh plant area measured from the same map method: 2.4 km2^2 (before seawall, 2010) → 1.6 km2^2 (after seawall, 2020). - A nearby marsh with no seawall: 2.3 km2^2 (2010) → 2.2 km2^2 (2020). - The seawall location had several storm surges between 2012–2019. Which evidence best supports the claim that the seawall is linked to habitat change?
