1. To lift heavy blocks

2. To smooth and level concrete surfaces

3. To measure distances

4. To cut through block

The correct answer is: To smooth and level concrete surfaces

A darby is a specialized tool commonly used in masonry for smoothing and leveling concrete surfaces. It typically consists of a long, flat board that is used to help finish the surface of freshly poured concrete. The primary function of the darby is to strike off excess material and create a flat, smooth finish, ensuring that the surface is even and ready for further treatment or application. The use of a darby is especially important in larger concrete pours, where maintaining a level surface can be more challenging. By using this tool, masons can effectively control and achieve the desired texture and flatness of the concrete, which is crucial for both aesthetics and structural integrity. This makes it an essential piece of equipment in masonry and concrete work, as it directly impacts the quality of the final product.
