Ithink the answer is either letter
a. or letter
b. what do you guys think?
which of these economic conditions existed in the united states when the civil war broke out?
a.) the north relied heavily on food supplies from the south.
b.) the south relied heavily on agricultural exports to europe.
c.) the north relied heavily on the natural resources of the south.
d.) the south relied heavily on the transportation network of europe.

The North during this time was more industrialized had more railroads/cities, meaning they had a good economy and did not rely on exports to other countries to pay for their debts.

This being said, it's not A, nor C and D.

The North did not need the South's agricultural assistance, nor natural resources. And, how is the South going to rely on Europe's transportation center?

Thus, B, is your answer.

The South relied heavily on cotton exports to Europe.
