This question is incomplete. Here is the part that is missing from your question:
Which of the following describes the main conflict in this excerpt best? character vs. self character vs. character character vs. nature character vs. society
Answer:
The correct answer is character vs. self.
Explanation:
In this excerpt of "Sophistication" by Sherwood Anderson we can see how this character is having an internal struggle with himself and his thoughts.
He is in a stage of transition from childhood to adulthood and has to process many new things that come into his life, which makes him feel lonely and old.
We can observe this in the following sentences:
<em>"Thoughts kept coming into his head and he did not want to think."
</em>
<em>"George Willard, the Ohio village boy, was fast growing into manhood and new thoughts had been coming into his mind."
</em>
<em>"I've felt old and a little tired."
</em>
In this way, we can say that the correct option is character vs self.
