Of the following, the best reason the united states might aid another country is to..
a. protect a trading relationship.
b. improve their global reputation.
c. the other country gain power.
d. develop another allied relationship.

The correct answer is A) Protect a trading relationship.

Explanation:

The United States has provided aid to many countries in history. This included  both monetary support, military support as well as diplomatic help.

One of the most famous example is that of the Marshall plan. A large loan program that was given to Europe countries after World War II.

By the end of the War, most European powers were devastated, both economically and socially.

The United States however, at the end of the war had a robust manufacturing sector ready to export. By aiding European countries through a Marshall plan, the US was able to create a huge European market for their goods.

The United States does the same thing in the Middle East where it protects Oil and Gas reserves which are imported back to the country.
