Answer:
1) A trade bloc between Canada, U.S., and Mexico
2) An organization to lower tariffs
3) A trade organization that equally benefits all nations
Explanation:
The North American Agreement for Free Trade is a trade block between the USA, Canada, and Mexico. NAFTA provides lower tariffs for its members but unlike the European Union that grants free access for Mexican citizens to Canada, and the USA, and vice versa North American workers from the US, Canada and Mexico do not have free access to these countries. In addition to this, it does not restraint the purchases for its members.
In the following years since the NAFTA pact was implemented, the US has exported much more to Canada and Mexico. And Mexico benefited from being a lower cost place for new plants, especially for huge American and Canadian Companies.
Therefore, it's 1,2 and 3.
