Respuesta :
Your answer is A. I had the same question and got it right on my quiz, so it should work for you too.
Answer;
US manufacturing had surpassed the level of industrialized Britain, and the United States had become the world's largest producer.
Explanation;
Industrialization began in the United States when Samuel Slater emigrated from Britain to Rhode Island in 1789 and set up the first textile factory on U.S soil.
-The American Civil War (1861–65) was the first truly industrial war; the increasingly urbanized and factory-based North fighting against the agriculture-focused South, and industrialization grew explosively afterward. By 1900 the United States had overtaken Britain in manufacturing, producing 24 percent of the world’s output.
