Passage Summary: Making a situation seem safer can actually backfire because it encourages people to act more recklessly, which can worsen the original problem.

Conclusion: Technical fixes for global warming might inadvertently lead to more global warming by encouraging higher carbon emissions.

Reasoning: Just as wide, safe-looking roads encourage drivers to take more risks, a 'fix' for global warming might make people feel safe enough to emit more CO2.

Analysis: The engineer is using an analogy to illustrate a broader principle of human behavior. The core idea is that when you mitigate the perceived danger of an activity, people tend to engage in that activity more frequently or intensely. To identify the principle, look for a statement that links the reduction of a risk with an increase in the behavior that creates that risk. It’s the 'safety net' irony: the more protected people feel, the more likely they are to walk closer to the edge.
