One key difference between the people can be the culture based on immigration origin. Most people in the south originate from colonies that used to be Spanish so there's a lot of Spanish cultural influence and Mexican while northerners are mostly of Germanic origin. One difference in economy is for example agricultural. Northern parts have harsher climate so things like tobacco can't grow as successfully while southerners have very dry and hot lands where you don't have dense coniferous forests.

Southerners were critical of the North and believed that the North's wage labor system was a bad system that they had no interest in putting into place in the south. The southern economy was based on slave labor and southerners wanted to continue the practice of slavery and prevent any transition away from this.
The answer would have to be option D "Justice." Media is used in different sort of ways. It will not be option A because entertainment is one of the main sources on why people use media to get the latest and entertain themselves on what is going on in that day. It will not be option B because school educators would use media that would help teacher his or her students on the lesson. It's not option C because advocacy is a public support which is mainly used in media campaigns.
Hope this helps!
