If a location is described as the 50 block of Street X, what is implied about its distance from the baseline?

• A. It is 50 blocks away from the origin
• B. It is relatively close to the baseline along Street X, within the 50-block interval from the origin
• C. It is exactly 50 blocks north of the baseline
• D. It is not near any baseline

Answer: (B)

The main idea is how a street grid uses a baseline to measure distance. When a location is described as the 50 block of Street X, it means you’re on Street X within the first fifty blocks away from the baseline. It signals proximity to the baseline, not an exact distance of fifty blocks or a specific direction beyond that it’s within that fifty-block band. So this indicates you’re relatively close to the baseline along Street X, within that 0–50 block interval. The other options imply exact distance, a different relationship to the baseline, or being far from any baseline, which isn’t what the label conveys.
