I will answer the question and then you can use the R.A.C.E method
Since Clemens always wanted to become a steamboat man on the great Mississippi River, he returned to the land of his youth to become a pilot, that is, one who steered the great paddle ships safely past the sandbars, rocks, floating trees, shifting currents and debris along the Mississippi. Clemens says in based in the Mississippi (1884): “In the space of one hundred and seventy six years the Lower Mississippi has shortened itself two hundred and forty-two miles. That is an average of a trifle over a mile and a third per year." The steamboat is a symbol of civilization, dominance and power. As such, it is a threat to nature and freedom. Life on the Mississippi was the book that launched the now well known Samuel Clemens' career as a “serious” author. Clemens, more well known by the title Mark Twain, paints Mississippi steamboat living and the workings of the river itself as a tribute to that great river.
