Final answer:
The Egyptian pyramids were managed projects, with engineers, organizers, and managers overseeing the construction, making the statement false.
Step-by-step explanation:
The statement that the Egyptian pyramids were completed without managers is false. The construction of the Egyptian pyramids was a monumental task that required extensive planning, organization, and management. The process was overseen by a head engineer and his subordinates, who were responsible for the efficient organization of skilled labor. The use of plans drawn on papyrus, the knowledge of geometry, and the highly effective government structure for tax collection and distribution of resources further emphasize the managed nature of these projects. Moreover, the workers who built the pyramids were not enslaved but were well-cared for and likely lived in higher standards than many others at the time.
