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: Group of answer choices The slack times for each task in the project are zero. The chain of activities (from start to finish) that has the largest sum of activity durations. The early start date and early finish date are always the same for each activity on the critical path. To reduce the project duration, you must reduce the slack time of a task on the critical path. Reducing a critical path will reduce the overall project duration
