Analysis of the test questions: "Qu Yuan" refers to the unconditional surrender of the atomic bomb dropped by Japan to the United States; "Su Wu" refers to the surrender of Japanese imperialism because the Soviet Union declared war on Japan on August 8th and sent troops to the northeast of China. The establishment of the anti-Japanese national United front and the War of Resistance against Japanese Aggression of the whole nation are the main reasons for the victory of the Anti-Japanese War. The strong cooperation of the international anti-fascist alliance and the support of the people all over the world are also the main factors for Japan's defeat and China's victory in the Anti-Japanese War. So it is incorrect to choose a, b, c and d as the answer.

Comments: With regard to War of Resistance against Japanese Aggression, we should pay attention to the connection with the hot issues of current politics: with regard to the principles and policies of Japanese aggression against China in modern times, we should pay attention to in-depth analysis of the Japanese government's current understanding of the war, form a correct understanding, and draw lessons from history.
