Question

1
2
3
4

Explanation:

To determine the distance between two places on a map, a scale is used. Feature 4 (the scale bar labeled "1,000 mi" and "1,000 km") allows readers to measure and calculate distances. Feature 1 is a title, Feature 2 is a legend, and Feature 3 is a compass rose (for direction, not distance). So the scale (Feature 4) is the key for distance.
