Question

Quizplus · Accepted Answer

The earliest start time of an activity following a node is determined by the largest of the earliest finish times for all activities entering the node. This is because all of the preceding activities must be completed before the activity following the node can begin. Therefore, the activity can begin as soon as the latest preceding activity is finished. Option A is incorrect as it implies that any preceding activity can trigger the start of an activity following a node which is not always the case. Option C is incorrect as it mistakenly states "earliest finish times" instead of "latest finish times". Option D is incorrect as option B is correct.
