Why is omitting the quadrant risky in a block-based description?

• A. Quadrants are optional and do not affect accuracy.
• B. It only matters for long descriptions, not for short ones.
• C. It helps to speed up dispatch.
• D. Because two blocks with the same number can exist in different quadrants, leading to misrouting.

Answer: (D)

The key idea here is disambiguation within the city’s block system. In many grids, each block number can appear in more than one quadrant (for example, a Block 100 can exist in both the NW and NE quadrants, or in other quadrant combinations). When you include the quadrant, you’re pinning the location to a single, unique block. Without that quadrant information, there’s ambiguity: two different places share the same block number, so a caller or dispatcher could route to the wrong area, delaying response and creating safety risks. So omitting the quadrant is risky because two blocks with the same number can exist in different quadrants, leading to misrouting.
