Answer:
A. Political and Economic Growth in the Late 1800s
Step-by-step explanation:
One reason the U.S. was able to become a world power was because of its political and economic growth in the late 1800s. During this time, the economy in the U.S. became stronger and more industrial. More people worked in factories and the U.S. produced more manufactured goods. Having a strong economy was very important because it meant the U.S. did not have to worry about its economy while it expanded its influence overseas.
