Final answer:
The correct answer is option B. The events in paragraphs 7 and 8 of the text develop the theme of courage by showing how the character faces internal conflict and learns to trust his knowledge and training despite increasing pressure and self-doubt, ultimately demonstrating personal growth and the overcoming of fears.
Step-by-step explanation:
The events described in paragraphs 7 and 8 of the provided text are likely meant to develop the theme of courage. This can be inferred from the conflict that has been presented: the character, presumably Mark Twain, must face a task that is made increasingly daunting by the addition of more people who contribute to his nervousness. As the story moves forward, Twain begins to second-guess himself due to the created pressure. This inner turmoil between self-confidence and self-doubt is at the core of the conflict.
The theme is further exemplified through the resolution where Twain learns to rely on his knowledge and training rather than giving in to his fears. The journey from fear to self-assurance underscores the theme of courage as opposed to themes of friendship, betrayal, or resilience. By the end of the narrative, we see that Twain, despite feelings of initial cowardice, reflects on his experiences, demonstrating personal growth and the importance of overcoming self-doubt to face challenges - hallmarks of a classic courage theme.
Therefore, within the context of the evidence provided, the most likely answer to the student's question is B. Courage.
