Which most likely explains why the United States joined NAFTA in 1993?

NAFTA reduced or eliminated many trade barriers among the United States, Canada, and Mexico, tying their economies more closely together. The agreement was intended to encourage trade across the region, not to give the United States an advantage over its neighbors or let it control their trade. Therefore, the best choice is “NAFTA eliminated tariffs and united the United States economically with its two closest neighbors.”
