Question

What did staying neutral during World War I do for the American economy?

A. It slightly hurt the economy.
B. It helped the economy.
C. It was neither good nor bad for the economy.
D. It caused a severe economic depression.

Answer 1

B. It helped the economy.

In fact, it was not until the end of the World War I that the US began to be considered as a world super economic power. The reason after that is that by staying neutral the US supplyed and selled weapons and war equipment to both parties of the conflict, getting profit out of it.
