Respuesta :
The North owned 85% of the factories and therefore were more industrialised and could produce machinery
The correct answer is B) The North owned 85 percent of the Nation's factories.
The statement that was an example of a Northern advantage in the Civil War is "b. The North owned 85 percent of the Nation's factories."
The northern states depended on the industry. That represented an enormous advantage compared to the south because in the manufacturing plants, the North could produce weaponry and supplies needed in the Civil War front. The North had built factories and manufacturing plants that offered jobs to workers and immigrants. On the other hand, the southern states depended so much on Agriculture and slavery that worked in the large plantation growing cash crops such as cotton. These plantations needed many slaves to produce the number of crops that had to be exported to Europe.
