In this section you will find after the passage a number of questions about the passage. You must choose the one which you think fits best . Write your answers in the spaces below (1.0pt)
Paper is named for papyrus, a reed like plant used by ancient Egyptians as writing material more than 5000 years ago. The Chinese invented the paper that we use 2000 years ago.
A piece of paper is really made up of tiny fibers, unlike a piece of material. The fibers used in paper, however, are plant fibers, and there are millions of them in one sheet. In addition to the plant fiber, dyes and additives such as resin may be used. Dyes can make the paper different colors; resin may add weight and texture.
Where do these fibers come from ? The majority of paper is made from the plant fiber that comes from trees. Millions are cut down, but new trees are planted in their place. Paper may be also made from things like old rags or pieces of cloth. Wastepaper, paper that has been made and used, can be turned into recycled paper. This recycling process saves forest, energy and reduces air and water pollution.

Choose the correct answer to complete the passage:
Everyday on radio, on TV, and in the newspaper, we hear, see or read about many problems in the world, for example, pollution problems.
Air pollution is the first kind. It mostly comes from fumes released from motorbikes, cars, airplanes, trains and poisonous gases emitted from factories. Also, waste is dumped anywhere, even in the city where many people are living. The second pollution problem is sea pollution. Many people earn their living from fishing in the sea, and the fish they catch feed many people. But the sea has become so polluted from oil spills and factory wastes that the fish are dying. This is not only killing the fish, but is also affecting those people who eat fish.
