Impact of Calendars on Total Float:
* Differing calendars (e.g., working days, holidays, or shifts) assigned to activities can result in varying total float values within a logical chain.
* Total float measures the flexibility of an activity and is calculated based on its calendar and logical dependencies.
PSP Study Guide References:
* The guide covers how calendar assignments influence float calculations and their potential to create disparities in a critical path.
Conclusion: The correct answer is B, as differing total float values typically indicate the use of different calendars for activities in the chain.
