Consider the following table of activities A through E in which A is the start node and E is the stop node. Assume all activities require the same resource. Predecessor Activity B A Duration (days) 5 15 10 5 5 C D A A B, C, D E On a plece of scratch paper, draw the early-start Gantt Chart associated with this table and determine the following. Assume the project is resource-constrained but not time-constrained. Assume only one resource is available and that resource can only do one activity at a time. Activities B, C and D all have the same early start date (time). Since there is only one resource, only one of the activities B, C, D can be started on the early start date. Which should be started first? Multiple Choice Either activity B or activity D O Activity B O Both activities C and D Activity C O Activity D
