OG18 A certain assembly project requires the completion of each of 5 tasks. In the diagram, the tasks are represented by circles labeled A–E and the number above each circle represents the number of days needed to complete the task. Arrows indicate prerequisite tasks. For instance, the arrow from Task A to Task C indicates that Task A must be completed before Task C can be started. Unless otherwise prohibited by these constraints, several tasks can be worked on at the same time. The project is complete once all 5 tasks are completed. Use the drop-down menus to create the most accurate statements based on the information provided.
