NAFTA primarily aims to eliminate duties and tariffs on goods traded between North American countries and to facilitate more free movement of workers.

• A. Establishes a common currency among member countries.
• B. Eliminates duties and tariffs on goods shipped between North American countries and allows freer movement of workers.
• C. Creates a mutual defense pact.
• D. Regulates environmental standards.

Answer: (B)

The main concept behind this is trade liberalization: reducing barriers to cross-border commerce and investment. NAFTA was designed to eliminate duties and tariffs on goods traded among Canada, the United States, and Mexico, making it easier and cheaper to export and import. It also creates mechanisms that allow certain workers to move more freely across the borders, specifically through temporary entry provisions for professionals under defined categories, which broadens opportunities for skilled workers within the region.

The other options don’t reflect NAFTA’s core purpose. A common currency was not part of the agreement, and it does not establish a mutual defense pact. While environmental provisions exist within the broader framework, the primary aim is about trade and investment, not environmental regulation.
