Based on the description of the graph, the correct statement that describes the economic impact of the CAFTA-DR free-trade agreement is:
The agreement caused imports from the U.S. to increase but led to a decrease in exports.
This conclusion is supported by the fact that exports from the U.S. surpass the exports to the U.S. by 2006, indicating that while imports from the U.S. may have increased, the trade dynamics favored U.S. exports over CAFTA-DR nations' exports. Additionally, without further details confirming a decrease in exports, this interpretation aligns closely with the observed trends.
