The most famous statue-the Sphinx in Egypt has been damaged. The experts are trying to find out the cause to protect it. As we all know, the Sphinx has the body of a lion and the face of a man. It was cut from limestone  near Egypt's pyramids about 4, 500 years ago. Not long ago a large piece of stone fell from the Sphinx's right shoulder. In order to protect the statue from more harm, a computer was placed on it to measure rainfall, wind speed and air temperature. The computer also measured the amount of water and air pollution, the direction of wind and the temperature of the statue itself. The effects of age, wind, water and pollution have greatly weakened the Sphinx. Sunlight, wind, water and pollution have been eroding the outside of the statue for centuries. The experts hope that the information from the computer will help protect it from more damage. They say the more they know about what is destroying the Sphinx, the more they can do to protect it. Which of the following is TRUE?
The Sphinx has completely fallen down. The Sphinx is made of a kind of rock, which can be destroyed by wind, rain and so on. The Sphinx is made of a kind of rock, which is hard enough not to be damaged by anything. The Sphinx is in too poor condition to be protected.
