Test analysis: This question mainly examines the slogan of the May 4th Movement. The slogans of the May 4th Movement mainly include "Fighting for sovereignty outside, getting rid of traitors inside", "Abolishing Article 21", "Opposing signing a peace treaty with Germany" and "Fighting to the death, giving me back Qingdao". The fuse of its outbreak was that the Paris Peace Conference transferred German privileges in Shandong, China to Japan, and China failed in diplomacy at the Paris Peace Conference, so the slogan of the May 4th Movement was of course related to Shandong's sovereignty. So the answer is B.
