I think its a) one event happened only as a result of the other
The correct answer is B) It has uniquely American themes.
American literature of the seventeenth and eighteenth centuries was different from the literature written in Britain during the same period in that it has uniquely American themes.
American literature in the 1800s is known as the Romantic Period. Writers and poets during this time wrote about specific situations that American people lived and faced during those years. They focused on topics that interested in American society and did not write about England or Europe. Among the famous authors of the time, we have Edgar Allan Poe, Herman Melville, Walt Whitman, and Nathaniel Hawthorne.
The Italian Prime Minister Orlando didn't speak English,and as this was the language used by the other 3 members of the Big Four Allied powers,he felt left out and sidelined. It became clear that Britain and France were going to renege on the promises of territorial gains they had made to Italy in 1915 to get Italy to join the war on the Allied side. France and Britain had come to the conclusion that Italy had been more of a liability than an aset during the war - considerable aid in terms of arms and other supplies had been sent to Italy,as well as thousands of French and British troops,to prevent an Ital;ian collapse.Orlando thus wasn't held in very high regard by Clemenceau or Lloyd George. So really combination of these factors caused Orlando to walk out of the conference in a huff,feeling he and Italy as a nation had been insulted.
