Which statement is supported by the information shown in the graph?

The bar graph shows that at the beginning of the Civil War, 95 percent of firearms manufactured in the United States were produced in the North. Answers (At the beginning of the Civil War, the North and South each had about the same population) and (At the beginning of the Civil War, the South had slaves and the North did not) are contradicted by the information shown in the graph. Answer (Having more slaves gave the South an advantage in the Civil War) correctly states that the South had more slaves, but no information in the graph indicates this was an advantage for the South. In fact, slavery didn’t help the South’s war effort; slaves could not be relied upon to fight for the South, and many ran away and joined the Union army.
