Naturalist writers used setting to enhance the theme of unpredictabilty in nature. Which four phrases in this excerpt from Stephen Cranes "The Open Boat" reflect the mercilessness of the sea?

None of them knew the color of the sky: Their eyes glanced level, and were fastened upon the waves that swept toward thern. These waves

were of the hue of slate, save the tops, whlch were of foaming white, and all of the men knew the colors of the sea. The horizon narrowed

and widened, and dipped and rose, and at all times Its edge was jagged with waves that seemed thrust up in points like rocks.

Many a man ought to have a bathtutb larger than the boat whlch here rode upon the sea. These waves were most wrongfuly and barbarously

abrupt and tall, and each froth-top was a problem in smal-boat navgation.
