"Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe to assure the survival and the success of liberty." (A) contains a hyperbole.
In literature, a hyperbole is a stylistic exaggeration. It is used to give a dramatic effect to a statement.
Here, the hyperbole is: "pay any price, bear any burden, meet any hardship, support any friend, oppose any foe." There are of course prices that the U.S. are going to refuse to pay, burdens they will not afford to carry, etc., but by exaggerating these commitments, Kennedy sounds more resolute and more persuasive.
I believe the correct answer is <span>B. Because most writing forms include narratives.
The first and last options aren't correct because an autobiographical narrative depicts real events from the writer's life, whereas a short story is fictional, which means the events and characters aren't real (and it doesn't have to be written in the 1st person).
The third option can be correct, but not in every case. Some of the best short stories don't include causes and effects. Actually, the causal relations are often concealed, and require a specific interpretation to explain them.
However, there is a narrative in both these forms. It means that they have a plot - introduction, climax, resolution (although they don't need to happen in a chronological order).</span>
