Wich of the following was an advantage held by the north during the civil war? a. the north had more natural resources. b. the north was fighting to defend itself. c. the north had superior military leaders. d. northern whites believed in the course of ending slavery.

The civil war wasn't self defense, it was a war over the issue of slavery and the rights of the states, so I'd eliminate B. The south actually had the superior military leaders, the North was struggling with that part, so it's not C either. And D isn't an advantage, it's just a stand view, so that leaves the answer to be A. The north had more natural resources. 

The answer is a and hi how are you doing
