B) mainly
The word "mainly" shows that the story of Huck Finn is more fiction than fact. He repeats this word many times when he is talking about the story being one of truth. This intensifier introduces the idea of the story being a bit exaggerated and fictional. The other words add to the characterization of Huck. He uses ain't simply to mean isn't. When he says "that ain't no matter" he means that it is no big deal. Without is used to mean exactly that and is not meant as an opposite.
The correct answer is He lies down on his side
This is a bit making it simple however since he had to do a bunch of things before he was able to do this. He had to clear a piece of a forest and to lie on his side in a special manner in order to see the palace and the beautiful rooms that he later described.
