The direct cause of the U.S. entry into World War II was the bombing of Pearl Harbor, which occurred on December 7, 1941. The correct answer is A - the bombing of Pearl Harbor. To determine the direct cause, we can look at historical events and their impact on U.S. involvement in the war.

While it is true that the invasion of Poland by Germany in 1939 played a significant role in the outbreak of World War II, it was not the direct cause of the U.S. entry into the war. The U.S. did express its opposition to Germany's aggression, but it did not declare war at that time.

Similarly, the capture of Belgium by Germany and the Battle of Britain were significant events during the early stages of the war, but they did not directly lead to the U.S. entry into the conflict.

To understand the direct cause of the U.S. entry into World War II, we need to focus on the attack on Pearl Harbor. On that day, the Japanese forces launched a surprise military strike on the U.S. naval base at Pearl Harbor, Hawaii. This unprovoked attack resulted in the deaths of over 2,400 Americans and the destruction of numerous American warships and aircraft.

As a response to this act of aggression, the United States declared war on Japan on December 8, 1941. Germany, as Japan's ally, then declared war on the United States, leading to America's entry into World War II.

Therefore, the correct answer to your question is A - the bombing of Pearl Harbor.
