Answer:
D. Trade with other nations increased as the US could sell many supplies
Step-by-step explanation:
This question might be referring to WWI, which lasted from 1914 to 1918 and involved most of the countries of Europe and their colonies, as well as other nations such as Russia, Japan, and the Ottoman Empire. The United States remained neutral for most of the war, until it joined the Allied Powers in 1917. During its neutrality, the United States benefited from its geographic isolation from the fighting, which allowed it to trade with both sides of the conflict and supply them with food, raw materials, and weapons. The United States also increased its industrial production and economic growth as a result of the war demand. Therefore, option D is the best answer, as it describes how the US took advantage of its distance from the war and increased its trade with other nations. The other options are incorrect because:
Option A is false because the US did want to produce many weapons, both for its own defense and for selling to its allies.
Option B is irrelevant because it does not describe how the US was affected by its geographic location during its neutrality.
Option C is false because European countries did not stop buying from the US, but rather increased their imports from the US to meet their war needs
