What do Huck’s words and descriptions tell you about his values— the things he appreciates and enjoys? The question refers to chapters 17-23.
Chapter 17--The Grangerford family. The descriptions indicate that Huck values family and wishes his own were more like Buck's. They are all friendly, dressed well, and have their own personal slave. They are educated and polished, even though they actively "hunt" Sheperdsons.
Chapter 18--More about the Grangerfords and Jim shows up. Huck says, "nothing ever sounded so good before" when he heard Jim's voice. Huck values friendship in Jim.
Chapter 19--The Duke and the Dauphin Come Aboard. Huck's descriptions of "lovely" raft life show his value of freedom and the river, a metaphor for life's journey. The two "visitors" to their raft provide entertainment and some protection for Jim.
Chapter 20--What Royalty Did to Parkville. The Duke conned the revival crowd and the Dauphin/King printed off a flier to help protect Jim while they run during the daytime. Huck appreciates entertainment, but he does not appreciate a thief.
Chapter 21, 22--Arkansas Difficulty. Sherburn kills the town drunk. Huck seems to admire Sherburn's straightfoward speech and resolute actions. He stood down the whole town bravely and sent them all home without being "lynched".
Chapter 23--Huck and Jim understand the "royalty" among them are dishonest and inconsiderate. They both agree that they can't stand anymore of them and pledge to find a way to get rid of the two as soon as possible.
