1. The problem asks whether crashing an activity that is not on the critical path will decrease the duration of the project. 2. In Critical Path Method (CPM), the critical path is the longest path through the project network and determines the shortest possible project duration. 3. Crashing means reducing the duration of an activity by allocating more resources. 4. If an activity is not on the critical path, it means it has some slack or float time. 5. Reducing the duration of a non-critical activity will not affect the overall project duration because the critical path duration remains unchanged. 6. Therefore, crashing a non-critical activity does not decrease the project duration. Final answer: B. False
