Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions from 1 to 5.
We can develop alternative sources of energy, and unless we try we will never succeed. Instead of burning fossil fuel we should be concentrating on more economic uses of electricity, because electricity can be produced from any sources of energy.
If we did not waste so much energy, our resources would last longer. We can save more energy by conservation that we can produce for the same money. Unless we do research on solar energy, wind power, tidal power, hydroelectric plants ... our fossil fuels will run out and we will all freeze or starve to death.
Many countries are spending much more time and money on research because the energy from the sun, the waves and the winds last forever. We really won’t survive unless we start working on cleaner and safer sources of energy.

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.
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.
