Directions: Read the passage and answer the question that follows.

Here is another intriguing wonder to the world. The Bermuda Triangle, also known as the Devil's triangle, is a triangular area of the Atlantic Ocean (305,000 sq km) where the disappearances of ships, airplanes, and boats has led to the belief that supernatural forces inhabit this area of the sea. Many planes, ships, and boats are believed to have disappeared in this triangle without a trace. This includes the disappearance of over 1,000 seamen and airmen. In most of these disappearances, it is the fact that no distress signal was ever received from the disappearing ships or planes that enhances the cloud of mystery that surrounds them. Although violent storms and downward air currents frequently occur in the area, scientists have not revealed anything extremely peculiar. Boundaries of the Bermuda Triangle are formed by drawing an imaginary line from Melbourne, Florida, to Bermuda, to Puerto Rico and back to Florida. Could there truly be an unnatural force at work in this geographical triangle or are these disappearances merely a coincidence? Numerous people remain unwilling to step over the boundary line into the Devil's Triangle. It is still an unsolved puzzle for scientists all over the world.
