How much of a medium structure can a 200' preconnect effectively reach?

A 200-foot preconnect is a firefighting hose line that can effectively reach significant distances to combat fires in various structures. Given that the question references a medium structure, which typically spans about 100 feet in height or width, a 200-foot preconnect allows for a considerable reach.

The choice indicating that a 200-foot preconnect can effectively reach 75% of a medium structure recognizes that the hose can extend far beyond the dimensions of many buildings, ensuring that firefighters can access multiple floors or areas within a medium-sized structure. This capacity to cover a substantial portion of a medium structure makes this answer appropriate, as it reflects the effectiveness of the hose length in practical firefighting scenarios.

The other options don't accurately capture the extent of coverage that a 200-foot preconnect can provide. 25% suggests a limited reach, while 50% and 100% do not align with the practical applications of the hose length in fire service operations. Thus, the choice that indicates 75% reflects a realistic and effective operational reach in firefighting.
