What is the purpose of distinguishing between a 'block' and a 'hundred block'?

• A. To describe the block position within the grid and improve efficiency of location reporting.
• B. To describe the speed limit.
• C. To determine the time of day.
• D. To categorize street types.

Answer: (A)

Distinguishing between a block and a hundred block provides a quick, two-level way to describe location within a city grid. The specific block tells you the exact street segment you’re referring to, while the hundred-block number communicates the broader area by counting blocks from a fixed starting point. This combination lets crews report locations rapidly and clearly, aiding dispatch, navigation, and coordination without lengthy addresses. The other options don’t describe location within the grid, so they don’t capture the purpose of this naming system.
