Use the attached Activity$-$on$-$Arrow or Activity$-$on$-$Node project networks to do the following:Calculate the ES$,$ EF$,$ LS$,$ LF times for each activity.Identify the critical path for the project.Calculate the Total Slack $($shared slack$)$ in the project as well as any Free Slack for individual activities.Revisit the network again and consider that specific resources $($Resources A$,$ B$,$ C & D$)$ are used for each activity and must be scheduled such that only one resource can be allocated to work on an activity at a time. The resources are identified by color and letter. For example, blue cannot be scheduled to work on two activities simultaneously. How long would it take to complete the project with these resource constraints?Did the changes caused by resource limitations from part $4$ above change the critical path? If so$,$ explain.
