Why does Thoreau go into such detail to describe the natural setting around the wild apple tree? A to show how the wild apple tree has produced a better fruit than has a tree cultivated by man B to demonstrate that man is happier out in nature than he is in the constructed areas of cities and towns C to state that it is as difficult for things to grow in nature as it is difficult for man to prosper in an uncharted wilderness D to make the point that wild apple trees have thrived just as man has thrived in a new land
