I believe the correct answer is that the <span>speaker may forget ideas or make grammatical mistakes.
Extemporaneous speaking has a lot to do with improvisation - it is a speech where you get a topic you haven't prepared for, and then you have 10-20 minutes to prepare and speak. This way, you cannot memorize everything that you wanted to say, and given that you aren't completely ready to speak, you may make some mistakes.

The ship in "O Captain! My Captain" is a metaphor for C. the United States.

Answer:
A monologue is a speech given by a single character in a story. In drama, it is the vocalization of a character’s thoughts; in literature, the verbalization. It is traditionally a device used in theater—a speech to be given on stage—but nowadays, its use extends to film and television
so i would put it in a way so your expressing what the monologue is and how its important.

“You are my sunshine” which means that you are so kind and wonderful so your the light in the world. Figurative language is kinda like a metaphor too.
