Answer:
The correct answers are A and C. The events that were instrumental in the United States entering World War II were:
-The Lend-Lease Act gave Congress the ability to provide military aide to other countries.
-The bombing of Pearl Harbor.
Explanation:
The United States, once World War II began in September 1939, proclaimed its neutrality in the conflict. There were several reasons for this: on the one hand, it was initially an internal conflict in Europe, that is, it was not a world conflict but a continental conflict. On the other hand, from the Franklin Delano Roosevelt government, the United States had embraced a policy of neutrality and non-interference in foreign affairs, leaving behind years of interventionist policies such as the Big Stick or the Monroe Doctrine.
But the truth is that the American government had an absolute ideological affinity for the Allies with respect to the Axis: France and Great Britain were its historical allies and its major trading partners; while on the other hand they did not share at all the imperialist and xenophobic measures carried out by Germany, Italy and Japan. This situation caused that indirectly America began to collaborate with the Allies, first through commercial concessions and then through the Lend-Lease Act, signed in March 1941, which allowed the federal government to supply armaments and food supplies to the Allies, without the need for active participation in battle.
Finally, the last reason that led to the United States entering the war was the Japanese attack on Pearl Harbor on December 7, 1941. It was a surprise attack by Japan, which sought to disable the American fleet in the Pacific. The Japanese, who knew about the ideological affinity and the collaboration provided by America to the Allies, considered that sooner or later the United States would be involved in the conflict, so they decided to attack preventively instead of waiting for American military movements.
This attack, which took the lives of more than 2,400 American men, prompted President Roosevelt to declare war on Japan, formally introducing the United States into World War II.
