Which statement is not supported by the passages about green corridors?

• A. Green corridors are a universal cure for heat without any costs.
• B. Green corridors can lower temperatures.
• C. They can face maintenance costs.
• D. They require space.

Answer: (A)

The idea being tested is whether a claim about green corridors is actually supported by the passages, not just plausible.

The passages acknowledge that green corridors can help cool areas by providing shade and through processes like evapotranspiration, and they also point out practical aspects like costs of upkeep and the need for space. So statements that green corridors can lower temperatures, or that they may incur maintenance costs, are consistent with what the passages say.

The unsupported claim is that they are a universal cure for heat with no costs. That statement overgeneralizes and adds a zero-cost condition that the passages do not claim; in reality, implementing and maintaining green corridors involves expenses and trade-offs, and results are not guaranteed everywhere.

So the not-supported statement is the one claiming a universal, cost-free cure.
