    (A) The year 2005 has been a year of disasters, but the bad luck of the planet won't end with the year. If scientists are right, planet earth is 31 years away from a major disaster. A small near-earth object with the potential to cause big damage has grabbed the attention of observers around the world. Astronomers have been monitoring the progress of a 390-metre-wide asteroid ever since it was discovered last June. They predict that it could hit the earth, causing huge damage, in 2036. They are asking governments to develop a strategy for deflecting the asteroid, which was named Apophis after an ancient Egyptian demon . NASA(美国国家航空和宇宙航行局)estimates that an impact by Apophis would release more than 100,000 times the energy of the nuclear blast that destroyed Hiroshima. The whole planet would see the effects of the dust released into the atmosphere. An Apophis hit is the worst possible near-earth scenario in recorded history. The asteroid has a 1 in 37 chance of hitting the earth. More than 30 years' warning of potential impact might seem like plenty of time. But scientists insist that there is actually little time left to decide what to do. It could take decades to design, test and build the technology to deflect the asteroid, they say. 16. Why have the astronomers been monitoring the progress of Apophis? A. To make a scientific study. B. To land on it in the future. C. To find ways to change its direction. D.
