Consider the following PERT$/$CPM network.

A project network with $10$ activities and $13$ directed arcs is shown.

Activity Start is connected to activity A and to activity B$.$

Activity A is connected to activity C and to activity D$.$

Activity B is connected to activity D$.$

Activity C is connected to activity E$.$

Activity D is connected to activity E and to activity F$.$

Activity E is connected to activity G$.$

Activity F is connected to activity G and to activity H$.$

Activity G is connected to activity H$.$

Activity H is connected to activity Finish.

Activity Finish has no arcs directed to other activities.

From the PERT$/$CPM network shown in the figure, create a list of activities and their predecessors. $($Enter your answers as comma$-$separated lists. If an activity does not have immediate predecessors, enter NONE.$)$
