Question

why would an engineer most likely use topography maps in his or her work?
to find an area used for camping
to define a political boundary line
to determine the best location for a new road
to find the ideal place to hike on a mountain

Explanation:

Topography maps detail elevation, terrain, and land features. Engineers rely on this data to plan infrastructure like roads, as they need to assess slope, terrain suitability, and construction feasibility. The other options relate to recreational use or political work, not typical engineering tasks.

Answer:

to determine the best location for a new road
