Question 79. . Consider the following statements regarding the critical path of a project network 1. 1. A path is a set of nodes connected by arrows which begin at its initial node of the network and end at the terminal 2. The length of a path in a network is the total time it takes to travel the path 3. The shortest path in a project network is called critical path 4. Activities on the critical path are called critical activities Of these statements:

1, 2 and 3 are correct
2, 3 and 4 are correct
1,3 and 4 are correct
1, 2 and 4 are correct

Discuss Question

Answer: Option C. -> 1,3 and 4 are correct

Question 80. . Consider the following statements regarding Early start and early finish times 1. The earliest possible that the job can begin, is called the early start of the job 2. The early finish of a job is early start time plus the job's completion time 3. For jobs with no predecessors, the early start is equal to start time of the project 4. The early start of a job is the largest of the early finish times of all of the immediately predecessors. Of these statements:
