Typical fence line posts should be set in undisturbed earth by _______.

• A. Shoveling
• B. Drilling
• C. Driving
• D. Drilling or driving

Answer: (D)

Setting fence line posts in undisturbed earth means keeping the surrounding soil as intact as possible while securing the post. Drilling or driving achieves this because drilling creates a narrow bore for the post, and driving pushes the post into the ground without excavating a large hole. In contrast, shoveling involves removing soil and creating a larger excavation, which disturbs the surrounding earth and can affect alignment and stability. So the typical method uses drilling or driving to minimize soil disturbance while providing solid support.
