The intended alignment for the motorway runs alongside the existing N20, which runs through Blarney, Mallow and Charleville. The new motorway forms part of the Project Ireland 2040 programme of infrastructure works. The first step in the project is to appoint a project manager and develop a project team. Once the team is selected and the staff is in place, the next task is to select a primary contractor to manage and oversee the construction. The following activities, their immediate predecessors, as well as the activity time estimates (in days) are standard for the planning and scheduling of this project: Activity Immediate predecessor Optimistic Most probable Pessimistic A 3 5 6 B 4 6 А, В А, В 5 6 7 D 7 9 10 E B 4 6 F 1 2 G 5 8 10 H D, F 8 10 I E, G, H 3 4 5 a) What are the critical activities?
