Directions: Read the passage and answer the following question:

None thought of sailing westward. For to men of those days, the Atlantic Ocean was known as the Outer Sea or the Sea of Darkness. There was nothing to be gained by going there, much to be dreaded. It was said that huge and horrible sea-dragons lived there, ready to wreck and swallow down any vessel that might venture near. An enormous bird also hovered in the skies waiting to pounce upon vessels and bear them away to some unknown eyrie. Even if any foolhardy adventurers should defy these dangers, and escape the horror of the dragons and the bird, other perils threatened them. For far in the West, there lay a bottomless pit of seething fire. That was easy of proof. Did not the face of the setting sun glow with the reflected light as it sank in the West? There would be no hope nor rescue for any ship that should be drawn into that awful pit.
