Final answer:
The statement about the Pole & Chariot System is true as it enabled efficient and simultaneous scene changes by using poles, ropes, and wheeled platforms.
Step-by-step explanation:
The statement that the Pole & Chariot System of moving scenery allowed all scenic shutters belonging to the same scene to be moved at once, increasing the efficiency of scenery shifts, is true.
This system was an ingenious method of changing scenes quickly and effectively.
Introduced during the Renaissance, the pole and chariot system utilized a series of poles and ropes and simple rigging to change scenery.
A backstage crew could move large sets of flats or wings simultaneously by pushing or pulling the chariots (wheeled platforms) connected by poles underneath the stage.
This significantly enhanced the speed and smoothness of scene transitions compared to manual lifting or dragging by stagehands, and is a precursor to the methods used in modern theatre, which often include computer automation and motorized curtains.
