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.
