Final answer:
Mark Twain's advice and lessons are conveyed through his thematic messaging, use of humor and satire, and literary techniques such as organization, hyperbole, and vivid description.
Step-by-step explanation:
The student is asking about the lessons or advice that Mark Twain offers through his writings. Twain, a prominent figure in American Literary Realism, provides wisdom and guidance through his use of dialect, regional humor, and satire, particularly in the interactions with the character Mr. Bixby. The thematic message Twain conveys is the importance of relying on one's knowledge and training over fear. The organization of Twain's work, such as the chronological recounting in his stories, helps to convey this advice. The use of hyperbole and vivid description enhances the reader's connection to the text and the message being conveyed. While the explicit 'six items' of Twain's advice are not listed, we can infer that they reflect Twain's themes of embracing knowledge, perceiving the humor in human nature, and the craft of writing, as suggested by the excerpt and Twain's broader literary contributions.
