Final answer:
The North American Free Trade Agreement (NAFTA) negatively impacted the manufacturing industries in the U.S., leading to the permanent elimination of nearly one million middle-class American jobs. The correct option is 1.
Step-by-step explanation:
The North American Free Trade Agreement (NAFTA) did not effectively destroy any sector in the U.S, as it had both positive and negative effects on different industries.
However, it is commonly believed that manufacturing industries in the U.S. were negatively impacted by NAFTA. The agreement led to the relocation of some manufacturing jobs from the U.S. to Mexico due to the availability of lower wages and greater profits for factory owners and shareholders.
This resulted in the permanent elimination of nearly one million middle-class American jobs from the manufacturing sector. The correct option is 1.
