When you know only the block number and quadrant, which description provides the most reliable locator?

• A. The block number and quadrant on a named street provide the precise location
• B. The block number alone with a quadrant reference is sufficient
• C. The quadrant reference alone is enough to locate the street
• D. The block number and quadrant on a named street, when possible, plus a landmark provides the most reliable locator

Answer: (D)

Locating someone reliably in a street grid comes from layering references. The block number and quadrant narrows you to a specific block within a quadrant, but without a street name you might still be unsure which street boundary you’re on. A named street fixes the exact street, and adding a landmark gives a fixed, visual reference you can confirm at a glance, making the locator robust in real-world conditions. That combination—block number and quadrant on a named street, when possible, plus a landmark—provides the most reliable description.
