Final answer:
The National Fallen Firefighters Foundation aims to reduce fatalities by 25% in five years and by 50% in ten years, effectively doubling their five-year target for a decade-long goal.
Step-by-step explanation:
The goal of the National Fallen Firefighters Foundation is quite specific in terms of the targets they have set to reduce fatalities among firefighters. They aim to decrease the fatalities by 25% in five years. Therefore, logically, for a ten-year goal, the intended reduction percentage would be greater.
Based on the options provided, a reasonable estimate given the progressive nature of goals over time would be a 50% reduction goal in ten years, which represents a doubling of the five-year target. The goal of the National Fallen Firefighters Foundation is to reduce fatalities by twenty-five percent within five years and by 30% in ten years.
