In a school construction project example, which activity could summarize sub activities?

• A. Digging a well.
• B. Landscaping the site.
• C. Painting a wall.
• D. Brick making.

Answer: (D)

The idea being tested is that some activities act as summary or parent tasks in a work breakdown structure, meaning they can be broken down into several sub-activities. Brick making fits this well because it’s a process that can be decomposed into distinct steps: sourcing raw materials (like clay and sand), mixing, forming the bricks, drying, firing or curing, quality checks, and transporting bricks to the site. Treating brick making as a single activity provides a clear umbrella under which all those sub-activities can be planned, scheduled, and coordinated, which is exactly how a WBS is used to manage scope and resources. The other options describe specific on-site tasks that can themselves be subdivided, but they’re not as natural a container for multiple sub-activities within the typical structure of a school construction project.
