As a little boy I read a book with a picture showing a man reading while floating in the Dead Sea. What a miracle! How would it feel to lie back in water so thick with salt that it was impossible to sink?              
Fed by the Jordan River and smaller streams, the Dead Sea is the lowest point on the earth's surface, and its water is ten times saltier than the Mediterranean. As evaporation  is its only outlet, salt and other minerals become super-concentrated.
Earlier this year, I drove down the long, steep hill to realize my dream. The shoreline was a broad area of bare salt-mud, but the water edge was out of sight. It seemed as if somebody had pulled the Dead Sea's plug . Eli Dior, an Israeli official, explained the problem "The Dead Sea is drying up. Every year, the surface falls about one meter, and as the water level falls, shallow areas are left high and dry."
Over the last half-century, the five neighboring countries have used up almost all the water flowing into the Dead Sea to meet human and agriculture needs. Result the Dead Sea is being emptied.              
With population in the neighbouring countries to double at least in the next 50 years, there is little hope of restoring the water being used in this area. No country has a drop to spare for the Dead Sea, where they know it will just evaporate. To dream of opening the dams and restoring natural balance is unrealistic.
Yet one ambitious high-tech dream may turn out to be not only the solution to the Dead Sea but also a ticket to peace around its shores. The "Red-Dead" is a proposed $5 billion project to bring sea water some 240 kilometers by pipeline and canal from the Red Sea to the Dead Sea. The Red-Dead may be the only solution, but even if the project is carried out successfully, the Dead Sea will be 10 to 20 meters lower than now and two thirds of its current size.
Whatever the future holds, the Dead Sea's magical mix of sun, mud, sea and salt will surely survive. Many might complain that the Dead Sea is half empty--but for me the Dead...
What's the passage mainly about ?
A) The Dead Sea is a miracle of the world.
B) How to save the environment of the Dead Sea.
C) The Dead Sea is slowly becoming smaller.
D) Why the Dead Sea is so salty.
C
The passage is mainly about the Dead Sea becoming smaller. The author states that the level of water in the sea has been falling year by year due to excessive use of water resources, and this problem cannot be solved easily because there are not enough sources for replenishing it. So we can conclude that option C) "the Dead Sea is slowly becoming smaller" best fits as an answer.
