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 statements referred by the question are:
a) It convinced the United States to dismantle its nuclear weapons.
b) It proved that a naval blockade was not an act of war.
c) It showed Cuba that communism should be stopped.
d) It brought the world dangerously close to nuclear war.
The correct statement is D. Historians agree the Missile Crisis was the closest the world got to have a nuclear war between the U.S. and USSR. Nothing before or after this came as close to be direct aggression from one of these countries against the other.
Statements A and C never happened: the U.S. has nuclear weapons until today, and Cuba didn't give up on communism.
Statement B doesn't fit the facts around the Missile Crisis. The naval blockade didn't lead to war only because the U.S. was defensive.
The British, it was a success.
