Final answer:
The statement is true. The North had a larger population and greater industrial capacity, producing nine times as many goods as the South, which would be represented on graphs comparing the two regions' industrial production.
Step-by-step explanation:
The statement that graphs representing northern and southern industrial production show significant differences is true. During the period leading up to and including the American Civil War, the North had a clear advantage in terms of both population size and industrial capacity compared to the South. The northern states' population was around 22 million, in stark contrast to the southern states' population of around 9 million. This disparity was also reflected in the workforce, where 1.3 million northerners were employed in factories, while only 110,000 southerners worked in similar industrial roles. Furthermore, northern factories produced nine times as many goods as southern factories, and the North had a superior rail system. These factors contributed to the North's ability to supply the growing military and move troops efficiently during the war. Thus, any graphical representation would likely show a pronounced variance in industrial output between the two regions.
