Answer 1

When World War I began in 1914, public opinion in the United States was largely isolationist and varied significantly. The most accurate statement regarding the sentiment at the time is:

It was split because the US was home to immigrants from countries on both sides of the war.

Many Americans had ties to countries involved in the conflict, leading to divided opinions. There were strong sympathies for both the Allies and the Central Powers due to the diverse immigrant population. The U.S. did not enter the war until 1917, after a period of neutrality and strong public sentiment against involvement.
