Question

What does Mark Twain satirize in this excerpt from "The £1,000,000 Bank-Note"?
It was a lovely dinner-party of fourteen. The Duke and Duchess of Shoreditch, and their daughter the Lady Anne-Grace-Eleanor-Celeste-and-so-forth-and-so-forth-de-Bohun, the Earl and Countess of Newgate, Viscount Cheapside, Lord and Lady Blatherskite, some untitled people of both sexes, the minister and his wife and daughter, and his daughter's visiting friend, an English girl of twenty-two, named Portia Langham, whom I fell in love with in two minutes, and she with me—I could see it without glasses. There was still another guest, an American—but I am a little ahead of my story.

long list of names required to address certain nobles

the English custom of holding frequent balls and dinner parties

the lack of importance given to Americans by the English

the eccentric attitudes of the British upper class

Answer 1

I believe Mark Twain is satirizing 'the long list of names required to address certain nobles' in this excerpt. 
Because, there is no mention of balls and dinner parties, or the importance of the Americans/British, or their eccentric attitudes, therefore, the first option is the correct one.

Answer 2

From the given multiple choices and the excerpt itself it is really easy to guess the answer. In this story Mark Twain uses many themes, but in this excerpt he shows the difference in people's rank and positions which he gives the full account of them and from the options the correct answer is long list of names required to address certain nobles which we can see Duke, Duchess, Countess etc.
