- A project has three sequences of activities (paths), two of which are critical. The critical paths of this project can be characterized in the following way: a. The slack times for each task in the entire project are zero. b. The chain of activities (from start to finish) that has the largest sum of activity durations. c. The early start date and early finish date are always the same for each activity on the critical path. d. To reduce the project duration, you must reduce the slack time of a task on the critical path. e. None of the above are correct.The time estimates (in hours) for the activities of a PERT network are given below: a) Draw the project network(b) Identify all paths through it and write critical path.(c) Determine the expected project lengthGiven the following information, draw the project network diagram compute the ,early , late and slake time for each activity.
