Final answer:
Aircraft manufacturing is not a high-volume system compared to automobile manufacturing, petroleum refining, and commercial bread baking, which are known for their high volume production processes.
Step-by-step explanation:
Among the options provided, which one is not an example of a high-volume system? Airplane manufacturing, compared to others, typically represents a lower volume but higher complexity production process. On the other hand, systems like automobile manufacturing, petroleum refining, waste treatment, and commercial bread baking are known for their high volume and standardized processes, often associated with economies of scale.
Automobile manufacturing is notorious for its assembly line production which enables mass production of vehicles. Petroleum refining is fundamental in producing the vast amounts of fuel required globally, and the process is run continuously, 24/7, to meet high demand. Similarly, commercial bread baking is a high-volume industry given the daily consumption needs for bread, making use of automated processes to bake thousands of loaves per day.
In contrast, aircraft manufacturing is not typically high-volume due to the complex, tailored nature of building aircrafts, along with longer production times and specialized labor. Hence, within the listed options, aircraft manufacturing is not an example of a high-volume system.
