Where on a map would you find detour information for construction zones?

• A. In the map legend.
• B. On the scale bar.
• C. In the index.
• D. By the compass rose.

Answer: (A)

Detour information is found in the map legend. The legend explains all the symbols, colors, and line styles used on the map, so any detour routes or notes related to construction zones are described there with the corresponding symbol or label. The scale bar is about distance, not route details. The index helps you locate places by name or topic on the map or in the atlas, not explain map symbols. The compass rose shows direction, not detour information. So, for understanding detour details and what to follow, the legend is the place to check.
