Final answer:
The invention of the cup seal did not lead to the development of the first functional pneumatic system.
Step-by-step explanation:
The statement that the invention of the cup seal led to the development of the first functional pneumatic system is False.
A pneumatic system uses compressed air to generate power. The cup seal is a component used in some pneumatic systems, but it is not the invention that led to the development of the first functional pneumatic system.
The first functional pneumatic systems were developed in ancient Greece, where they used water and air pressure to operate musical instruments and other devices. One example is the hydraulic organ, which used water pressure to produce sound.
