Which regional difference (North or South) contributed most to the outbreak of the Civil War? Explain.

South

Explanation:

As America was being colonialized, the South was more suitable for cash crops, which were grown on plantations with slaves. As the North industrialized, the South didn't need to because they had slaves, but the North kept pushing the South to abolish slavery, pressuring it to do something (unsuccessfully advocate in the government) or secede from the Union. If slavery was abolished, the South would have lost its most valuable labour force and economic progress.

the section of the chart that represents a point at which a bill needs approval from a majority of people in both chambers to advance is j, as this is the only section before the bill becomes law which has both rows (symbolizing the chambers) converging into one, meaning that the two parts of the congress have to approve of it before it can march on with the process.
