Final answer:
Tucker's conflict, dealing with self-doubt and external pressure, is resolved when he relies on his knowledge and training, as reflected in the falling action and resolution of the story. This illustrates the theme of trusting one's abilities.
Step-by-step explanation:
Tucker's conflict in the Mark Twain excerpt is resolved as part of the story's structure. Initially, Twain feels confident in his ability to run a crossing, but doubt begins to surface when Mr. Bixby sends more people to oversee the task, increasing Twain's anxiety. Through the rising action, the tension escalates, showcasing the contrast between Twain's initial confidence and the growing pressure. Ultimately, in the falling action and resolution, the conflict is addressed. Twain must fall back on his knowledge and training rather than succumb to his doubts. This resolution ties back to the theme that, in challenging situations, one must trust in their skills and education. The resolution can also lead to a reflection on the overarching theme and the lessons learned from the experience.
