Answer :
(A) The materialism of the North would prevent Northerners from fighting an idealistic war.
Answer:
D) The economic and military resources of the South would outlast those of the North.
Explanation:
The economy of the South was mainly dependent on the farms and industrialization of the North was well known. Cotton trade was an essential element to its economy and so was the institution of slavery. But it should be noted here that other factors played a vital role in the war. The South was expecting the involvement of other nations but when it proved wrong, the spirit to win from the materialistic and economically rich north became faded.
