  2. Find the critical paths and state the minimum time for completion of the project.
  3. Find the activity with the greatest float time and state the value of its float time.
  4. On Figure 2 opposite, draw a cascade diagram (Gantt chart) for the project, assuming that each activity starts as late as possible.
