Final answer:
The air from a Low-Pressure Air Compressor (LPAC) is stored in a storage tank, and gases move from a high-pressure area to a low-pressure area.
Step-by-step explanation:
The air supplied by a Low-Pressure Air Compressor (LPAC) is typically stored in a storage tank until it is used. Answering the multiple-choice question, the correct option is a) Storage tank. Similarly, in physics, we learn about the movement of gases, and the principle that gas moves from an area of high pressure to an area of low pressure is key to understanding various phenomena in fluid dynamics and thermodynamics. Therefore, the correct answer to the multiple-choice question regarding gas movement is d) high; low.
