The direct answer is B: Japan showed its rise as a modern military power. The Russo-Japanese War took place in 1904–1905 between imperial Russia and Japan. Japan, an Asian country that had modernized rapidly, defeated a major European empire. Reasoning step by step: Russia represented an established European great power; Japan had adopted modern industry, administration, weapons, and military organization; Japan then won important land and naval battles; this demonstrated that a non-European Asian state could compete successfully with a European power. Option A is wrong because European powers did not all disappear; they remained influential. Option B is correct because the war revealed Japan's new strength and changed ideas about the world balance of power. Option C is wrong because American independence occurred much earlier, in 1776.

The invasion of Poland was decisive because it turned the European crisis into an open international war. Germany attacked Poland on 1 September 1939, using force to expand its territory. Britain and France had promised support to Poland and, after the attack, declared war on Germany. This made the conflict much wider than a dispute between Germany and Poland. Therefore, option A is correct. The other choices describe unrelated events: the United Nations did not end, the French Revolution had occurred much earlier, and America had become independent in the eighteenth century.

Remember that the invasion itself did not mean that every country immediately joined the war, but it was the direct trigger for the declarations by Britain and France. It is commonly treated as the beginning of the Second World War in Europe. The date 1939 is useful for examination revision. The key chain is: German invasion of Poland, British and French declarations of war, and the expansion of the conflict into World War II. Thus the supplied answer is accurate.

Japan attacked the US naval base at Pearl Harbor on 7 December 1941.

D-Day refers to the Allied landing in Normandy, France, on 6 June 1944, during the Second World War. The operation opened a major western front against Nazi Germany. By establishing beachheads and bringing large numbers of troops and supplies into occupied France, the Allies began a sustained advance across Western Europe. This helped liberate France and other territories and placed increasing military pressure on Germany from the west, while the Soviet Union fought on the eastern front. Therefore option A is correct. The other choices concern unrelated developments: German reunification came in 1990, the Chinese republican revolution belonged to a different context, and African decolonisation occurred mainly after the war.

NATO was created in 1949; the Warsaw Pact was created in 1955. These organizations represented collective military security and the division of Europe into rival power blocs. Option A is correct because both alliances were military groupings facing the opposing side, even though the Cold War did not usually become a direct full-scale war between the two superpowers. Option B, ancient trade fairs, has no connection with twentieth-century military alliances. Option C, the Agricultural Revolution, concerns changes in farming and production. Option D, Renaissance art, belongs to an earlier cultural period. Exam cue: NATO means the Western bloc; Warsaw Pact means the Soviet-led Eastern bloc.
