Draw a network diagram representing the following logic: as the project starts, activities A and B can be performed concurrently. When activity A is finished, activities C and D can start. When activity B is finished, activities E and F can start. When activities D and E are finished, activity G can start. The project is complete when activities C, F, and G are finished. Use both the activity-in-the-box and the activity-on-the-arrow formats.
