Discuss how variations in activity durations may influence paths through a network and could possibly change which one is the critical path.

What will be an ideal response?

This answer should be fairly straightforward. Durations can directly influence path
overall length and may require some activities to be rearranged in the network based on
constraints durations may present. As the critical path is a direct function of activity
duration, it will also be directly affected based on the combination of activities. Therefore
if activities are moved to other paths that result in changing the path duration, the
critical path may also change.
