Answer:
Its story is told mostly in dialect, and it focuses on local people and topics.
Step-by-step explanation:
"The Celebrated Jumping Frog of Calaveras County" by Mark Twain is a prime example of Regionalism because it focuses on local people and topics, and is told in a regional dialect. The story is set in Calaveras County, a rural area of California, and the characters are typical of the area. The narrator, Simon Wheeler, speaks in a dialect common to the region, and this adds to the story's realism and authenticity.
Additionally, the story highlights the customs, values, and attitudes of the people in the region, such as their love of gambling and storytelling. By focusing on the local, Mark Twain highlights the distinctiveness of the region and its people, which is a hallmark of Regionalism in American literature.
