5. \begin{figure}[h] \end{figure} The network in Figure 2 shows the activities that need to be completed for a project. Each activity is represented by an arc and the duration of the activity, in days, is shown in brackets. The early event times are shown in Figure 2.

1. Complete Table 1 in the answer book to show the immediately preceding activities for each activity. It is given that \(4 < x \leqslant m\)
2. State the largest possible integer value of \(m\).
3. 1. Complete Diagram 1 in the answer book to show the late event times.
   2. State the activities that must be critical.
4. Calculate the total float for activity G. The resource histogram in Figure 3 shows the number of workers required when each activity starts at its earliest possible time. The histogram also shows which activities happen at each time. \begin{figure}[h]

5. Complete Table 2 in the answer book to show the number of workers required for each activity of the project.
6. Draw a Gantt chart on Grid 1 in the answer book to represent the activity network.
