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.

1. According to the passage, the paper that we use was first invented by

A. the Chinese B. the Egyptians C. ancient cultures D. foresters

2. What is the main ingredient in most paper ?

A. resin B. cardboard C. plant fiber D. papyrus

3. According to the passage, the primary source of the plant fiber used in paper is

A. rags B. trees C. fabric D. wastepaper

4. According to the passage, recycling paper is

A. bad for the environment C. good for the environment

B. wasteful D. economical

5. According to the passage, recycling paper does all of the following EXCEPT

A. reduce the need for ink C. save energy

B. save forests D. reduce air pollution

Read the following passage and write the letter A, B, C or D on the top of the first page to indicate the correct answer to each of the questions.

In the course of its history, human inventions have dramatically increased the average amount of energy available for use per person. Primitive peoples in cold regions burned wood and animal dung to heat their caves, cook food, and drive off animals by fire. The first step toward the developing of more efficient fuels was taken when people discovered that they could use vegetable oils and animal fats in lieu of gathered or cut wood. Charcoal gave off more intensive heat than wood and was more easily obtainable than organic fats. The Greeks first began to use coal for metal smelting in the 4th century, but it did not come into extensive use until the Industrial Revolution.

In the 1700s, at the beginning of the Industrial Revolution, most energy used in the United States and other nations undergoing industrialization was obtained from perpetual and renewable sources, such as wood, water streams, domesticated animal labor, and wind. These were predominantly locally available supplies. By mid-1800s, 91 percent of all commercial energy consumed in the United States and European countries was obtained from wood. However, at he beginning of the 20th century, coal became a major energy source and replaced wood in industrializing countries. Although in most regions and climate zones wood was more readily accessible than coal, the latter represents a more concentrated source of energy. In 1910, natural gas and oil firmly replaced coal as the main source of fuel because they are lighter and, therefore, cheaper to transport. They burned more cleanly than coal and polluted less. Unlike coal, oil could be refined to manufacture liquid fuels for vehicles, a very important consideration in the early 1900s, when the automobile arrived on the scene.

By 1984, non-renewable fossil fuels, such as oil, coal, and natural gas, provided over 82 percent of the commercial and industrial energy used in the world. Small amounts of energy were derived from nuclear fission, and the remaining 16 percent came from burning direct perpetual and renewable fuels, such as biomass. Between 1700 and 1986, a large number of countries shifted from the use of energy from local sources to a centralized generation of hydropower and solar energy converted to electricity. The energy derived from non-renewable fossil fuels has been increasingly produced in one location and transported to another, as is the case with most automobile fuels. In countries with private, rather than public transportation, the age of non-renewable fuels has created a dependency on a finite resource that will have to be replaced.

Alternative fuel sources are numerous, and shale oil and hydrocarbons are just two examples. The extraction of shale oil from large deposits in Asian and European regions has proven to be labor consuming and costly. The resulting product is sulfur-and nitrogen-rich, and large scale extractions are presently prohibitive. Similarly, the extraction of hydrocarbons from tar sands in Alberta and Utah is complex. Semi-solid hydrocarbons cannot be easily separated from the sandstone and limestone that carry them, and modern technology is not sufficiently versatile for a large-scale removal of the material. However, both sources of fuel may eventually be needed as petroleum prices continue to rise and limitations in fossil fuel availability make alternative deposits more attractive.
Question:It can be inferred from the first paragraph that

A. coal mining was essential for primitive peoples

B. the Greeks used coal in industrial productions

C. the development of efficient fuel was a gradual process

D. the discovery of efficient fuels was mostly accidental
