Easy -1.8 This is a straightforward recall question testing basic definitions in critical path analysis. It requires only recognition of fundamental concepts (that the first activity starts at time zero) with no calculation, problem-solving, or multi-step reasoning—significantly easier than typical A-level questions.
1 Which of the following statements about critical path analysis is always true? Tick ( \(\checkmark\) ) one box.
All activity networks have exactly one critical path. □
All critical activities have a non-zero float. □
The first activity in a critical path has an earliest start time of zero. □
A delay on a critical activity may not delay the project. □
The first activity in a critical path has an earliest start time of zero
