If you have this question:

Read this excerpt from Mark Twain's Adventures of Huckleberry Finn, a novel that gives a lively portrayal of places along the Mississippi River. Which sentence in the excerpt depicts the welcoming nature of the countryside?

The sun was up so high when I waked that I judged it was after eight o'clock. I could see the sun out at one or two holes, but mostly it was big trees all about, and gloomy in there amongst them. There was freckled places on the ground where the light sifted down through the leaves, and the freckled places swapped about a little, showing there was a little breeze up there. A couple of squirrels set on a limb and jabbered at me very friendly.

The answer is from plato-  A couple of squirrels set on a limb and jabbered at me very friendly.
