4. 10

The correct answer is: 10

Glacial till is a type of soil deposit resulting from the advance and melting of glaciers, and it typically consists of a mixture of clay, silt, sand, and gravel. The load-bearing capacity of glacial till is influenced by its composition and density but generally falls within certain ranges. The correct answer aligns with standard civil engineering practices, where glacial till is commonly understood to have a load-bearing capacity of approximately 10 tons per square foot. This value reflects the typical structure and compaction levels found in glacial till deposits, allowing for substantial support for construction projects when properly analyzed and prepared. Understanding this value is crucial for construction supervisors, as it ensures that they can accurately assess soil conditions at a building site, accommodate designs based on soil parameters, and make decisions that promote the safety and stability of structures.
