The correct response in the context of recent renegotiation of NAFTA, which resulted in the United States-Mexico-Canada Agreement (USMCA), would be:
**Agricultural trade was improved across all member nations.**
This is because the USMCA includes provisions that benefit agricultural trade, allowing for greater access to markets and improved trade conditions for agricultural products among the United States, Canada, and Mexico. The other statements regarding government contracts, a uniform currency, and a decrease in the economic gap are not accurate representations of the outcomes of the agreement.
