It encouraged the belief that European dominance was not unbreakable and influenced nationalist movements in parts of Asia. B is wrong because Europe did not conquer all Asia.

The direct answer is A: Britain and France declared war on Germany. Germany invaded Poland on 1 September 1939. Britain and France had promised to support Poland, so after the invasion they declared war on Germany on 3 September 1939. Step by step: Germany attacked Poland; the attack violated the European security arrangement and the promise made to Poland; Britain and France responded with declarations of war; the conflict therefore expanded beyond a local European attack and became the beginning of the Second World War in Europe. Option A is correct because those declarations brought two major powers directly into the conflict. Option B is wrong because Japan did not immediately surrender and later fought the Allies. Option C is wrong because the United Nations did not yet exist and did not attack Germany. Option D is wrong because Russia did not free France in response to the invasion. Memory cue: Poland, 1939, Britain and France, World War II.

Direct answer: A. Japan attacked the United States naval base at Pearl Harbor in Hawaii on 7 December 1941. The attack led the United States to declare war on Japan and enter World War II directly.

The attack therefore changed the scale and global importance of the war, although fighting had already begun in Europe and Asia before Pearl Harbor. B is wrong because the Renaissance occurred centuries earlier. C is historically false; France did not rule the United States.
