Final answer:
The Non-Intercourse Act of 1809 opened trade with all nations except Britain and France, while attempting to continue economic pressure on those two countries without harming the American economy as much as the previous Embargo Act had done.
Step-by-step explanation:
The Non-Intercourse Act of 1809 was enacted in response to the economic difficulties brought about by the previous Embargo Act of 1807, which had aimed to pressure Britain and France to respect American neutrality by banning all American ships from international trading. However, it primarily harmed the American economy. As President, James Madison sought to ease these pressures without entirely reversing course. Consequently, the Non-Intercourse Act allowed trade with all nations except Britain and France, aiming to continue putting economic pressure on these two warring nations while allowing American commerce with the rest of the world to resume.
The Non-Intercourse Act of 1809 opened trade with all nations except Britain and France, which is correctly described by statement A. This effectively lifted the total ban on international trade from the Embargo Act but continued to prohibit trade with the two countries most involved in interfering with American shipping.
