What should you do when the exact block number is uncertain but a landmark is available?

• A. Describe the closest confirmed block and include the landmark as the primary locator; seek clarification for the block when possible
• B. Use only the landmark, ignore the block
• C. Invent a block number
• D. Wait for further instructions

Answer: (A)

When you’re not sure of the exact block number but you have a landmark, anchor your description to the closest confirmed block and use the landmark as the primary locator, then seek clarification for the exact block when possible. This keeps your location precise and quickly identifiable, while still allowing you to tighten the block reference later. Relying on the landmark alone can be too vague if multiple blocks share the area, and inventing a block number would be inaccurate. Waiting for instructions could delay situational awareness if action is needed now.
