Answer:
to give Britain the American aid it needed but could not pay for
Explanation:
The Lend-Lease Act, or "the United States Defense Promotion Act," which was signed by President Roosevelt on March 11, 1941, gave the American President the right to "sell, transfer title, exchange, lend or otherwise discard any article of defense for any government with which the president considers it vital to the defense of the United States. The term "any defense article" was understood to mean weapons, military equipment, ammunition, strategic raw materials, ammunition, food, and consumer goods required by the army and internal security forces, as well as any information of military importance.
When this law was proposed, President Franklin D. Roosevelt found it extremely important that the US Congress approve it because he wanted to give Britain the American aid it needed but could not afford.
