PLEASE HELP I picked the first option but i think i am wrong

Its the last option. More deaths mean fewer workers.

Its the Civil War, so disease has nothing to do with it; neither does battles or national elections.

D. More deaths means fewer workers.

Explanation:

By process of elimnation:

A. is incorrect because diesease is unrelated. War casualties do not equal diesease in population.

B. is incorrect because more deaths does not necessarily mean more battles. Infact, usually the opposite, because a side could be forced to surrender if it doesn't have enough troops.

C. is incorrect because elections would carry on just the same whether or not war casualties were high.

becasue in the south they disallowed slavery but in the north slavery was illegial this boilled into because mexico wanted slavery
