Question II. Read the passage and answer the questions below

The search for alternative resources of energy has resulted in various directions. Many communities are burning garbage and other biological waste products to produce electricity. Changing waste products into gases or oil is also an efficient way to dispose of waste. Experimental work is being done to make synthetic fuels from coal, or coal tars. But to date, that process has proved expensive. Other experiments are underway to harness power with giant windmills. Geothermal power, heat from the earth, is also being tested.
Some experts are trying to revive hydroelectric power which is derived from streams and rivers. Fifty years ago, hydroelectric power provided one third of the electricity used in the United States, but today it supplies only four per cent. The oceans are another source of energy. Scientists are studying ways to change the energy of ocean currents, tides, and waves into electricity. Experiments are also underway to make use of temperature differences in ocean water to produce energy.

Most of the world’s energy comes from the sun. The sun’s energy is in wood, oil, and other things that people use for energy.
VI. Read the text then answer true or false
People use many sources of energy. Ancient people used only their arms, hands, and simple tools until they discovered fire. Later, people learned to use the energy of the wind to sail ships. Then they learned to use animals to do work. In the eighteenth and nineteenth centuries, people began to use machines. The first machines used steam. They burned coal to heat water. The hot water turned into steam, and the steam engine did the work. Later, people began to use the gasoline engine, and today people are using nuclear energy. Energy is one of the basic concepts, or ideas, of physics. It is the ability to do work. Without energy we could live. We need energy to work, and scientists are always looking for new sources of energy.
1. None of the world’s energy comes from the sun. F
2. Wind, steam, and gasoline are sources of energy. T
3. People have never used nuclear energy. F
4. Energy is the ability to do work. T
5. We need new sources of energy. T
