Figure 1 below shows an activity diagram for a project. Each activity requires one worker. The duration required for each activity is given in hours.
\begin{enumerate}[label=(\alph*)]
\item Find the earliest start time and the latest finish time for each activity and insert their values on Figure 1.
\item On Figure 2 opposite, complete the precedence table.
\item Find the critical path.
\item Find the float time of activity $E$.
\item Using Figure 3 on page 5, draw a resource histogram to illustrate how the project can be completed in the minimum time, assuming that each activity is to start as early as possible.
\item Given that there are two workers available for the project, find the minimum completion time for the project.
\item Given that there is only one worker available for the project, find the minimum completion time for the project.
