Reduce Hazard Risk Practice Test

A coastal town is threatened by hurricanes each summer. The town installs an early warning system that sends alerts to phones and triggers sirens when a hurricane is likely to make landfall within 24 hours. Which statement is supported by this evidence about how the warning system reduces risk?

Remember: the warning system cannot prevent hurricanes from forming; it can only lower the impacts on people and property.

A community near a river has frequent floods. The town can choose one main strategy this year: (1) build homes on higher foundations and use water-resistant materials, or (2) paint “NO FLOOD” signs along the river to discourage flooding. Which strategy reduces flood risk, and why does it reduce impact rather than prevent the hazard?
