Some 3 weeks after the German invasin of Poland, he urges Congress to amend the neutrality act that barred the exports of minitions. Then Roosevelt soon realized that Americn invlvement is unavoidable and started a compaign to prepare U. S. degenses for the likely conflict.

------------------Is that correct???

I'm not sure about the first one; another teacher may be able to help you there. I'd choose C, but I also know there were several nations and borders that were created/determined by different treaties after WWII.

The second one is incorrect. The one, single incident that catapulted the US into WWII was the attack on Pearl Harbor.

Second one can be aruged apon because there was the Lend Lease Act between The U.k and USA.

1. The correct answer is C. The Five-Power Treaty, the Four-Power Treaty, and the Nine-Power Treaty were all attempts to ensure international peace. These treaties were a result of the Washington Naval Conference held in 1921-1922, where representatives from various countries, including the United States, Great Britain, Japan, France, and Italy, came together to discuss naval disarmament and Pacific security. The Five-Power Treaty aimed to limit the naval arms race by placing caps on the total tonnage and individual ship sizes for each participating country. The Four-Power Treaty sought to establish mutual respect for each other's territory in the Pacific, while the Nine-Power Treaty aimed to guarantee China's territorial integrity and maintain the principle of the "Open Door" policy.

2. The correct answer is A. Japan's bombing raid on Pearl Harbor prompted the overwhelming support of the American public for the entry of the United States into World War II. On December 7, 1941, Japanese forces launched a surprise attack on the U.S. naval base at Pearl Harbor in Hawaii. This attack resulted in significant loss of life and the destruction of many American ships and aircraft. The following day, President Franklin D. Roosevelt addressed Congress, declaring war on Japan, which ultimately led to the United States fully entering the war. Prior to the Pearl Harbor attack, the United States had remained officially neutral, although it had been providing support to European countries threatened by Nazi Germany.
