A story is about a self-proclaimed emperor in the United States. People who know a little about American history know that there are many strange things in American history and reality, but there is one thing that is not there, the emperor. The imperial system has not been implemented, so it is impossible to have so-called emperors. However, the San Francisco Chronicle, one of the main San Francisco newspapers on January 9, 1880, published a message on the front page of the headline: "The King crashed. ", Announced" the death of Norton I, Emperor of the United States and the protector of Mexico ". From the above, what is the author most likely to tell next? ['Analysis of the reasons why the United States did not implement imperialism.', 'A brief introduction to the nature and purpose of the newspaper.', 'Tell the reader about the evolution of the American political system.', 'Introducing the legend of Norton I.']
