The Bermuda Triangle
The Bermuda Triangle is an area of water in the North Atlantic Ocean that stretches from the island of Bermuda to Florida to Puerto Rico. Since the 1940s, a large number of planes and boats have mysteriously disappeared in this area. In many cases, these planes and boats were traveling in good weather conditions without any known problems, when they suddenly disappeared and were never seen or heard from again.
Over the years many people have tried to explain the strange disappearances. Some say that there must have been sudden storms or bad weather. Others say that gases in the water might have caused boats to sink. Some people even say that aliens are responsible. Scientists have been unable to agree on why so many boats and planes have disappeared in this area. But, one thing is for sure—until an explanation is found, people will continue to wonder what mysterious things are happening in the Bermuda Triangle.

[AUDIO: Rock the Earth, page 50, CD2 Track7; the first three paragraphs:

Thousands of meteorites enter Earth’s atmosphere and fall harmlessly to the ground each year. One widely accepted theory is that the impact of an asteroid 6 miles (10 kilometers) in diameter could have been responsible for the extinction of many life forms, including the dinosaurs 65 million years ago. 

On June 30, 1908, a small asteroid of approximately 200 feet (60 meters) in diameter exploded over Siberia. The explosive energy from the meteor was so great that half a million acres of Siberian forest were devastated. 

In order to protect against such events, NASA has developed ways to monitor Near-Earth Objects (NEOs). For example, the Near-Earth Asteroid Rendezvous (NEAR) is a spacecraft that monitors Eros, one of the largest asteroids being studied. This huge flying rock is the shape of a potato, and its size is 170 square miles (442 square kilometers). Scientists believe that it might strike Earth in 1.5 to 5 million years. None of these NEOs is likely to hit the earth over the next hundred years. However, scientists are concerned because, at present, there are about 900 asteroids circulating our solar system. If an asteroid the size of Eros fell on Earth in the middle of the Atlantic, it would have catastrophic effects.

19. NEAR is   _____.
A. a tornado
B. a meteorite
C. a spacecraft 
D. an asteroid
