Which issue largely related to mexico became a major controversy in the 1990s?
drugs
reduction in border patrols
illegal immigration
cheap production of goods

The correct answer is D) cheap production of goods.

The issue largely related to Mexico that became a major controversy in the 1990s was the cheap production of goods.

With the signing of NAFTA, the North America Free Trade Agreement, many people in the United States started to worry about the quality of products that could be imported from Mexico. Let's remember that NAFTA opened the border to free trade of many products between Mexico, Canada, and the United States. Another concern for United State citizens and government was the fact that many U.S. companies decided to take their fabrics or offices from the U.S. to put them in Mexico because the labor is cheaper in that country.
