II. Read the following passage and choose the correct answer.
The search for alternative sources of energy has led in various directions. Many
communities are burning garbage and other biological waste products to produce
electricity. Converting waste products to gases or oil is also an efficient way to dispose of
waste.
Experimental work is being done to derive synthetic fuels from coal, oil shale and coal tars.
But to date, that process has proven expensive. Other experiments are underway to
harness - power with giant windmills. Geothermal power, heat from the earth, is also being
tested.
Some experts expect utility companies to revive hydroelectric power 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 percent. The oceans are another potential
source of energy. Scientists are studying ways to convert the energy of ocean currents,
tides, and waves to electricity. Experiments are also underway to make use of the
temperature differences in ocean water to produce energy.

Read the following passage and choose the correct answer.

We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution. On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like nonrenewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the winds blow throughout the year. The five types include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, energy from moving water; biomass, energy from dead plants and microorganisms and finally, energy from the wind.

36. Which sentence is NOT TRUE about non-renewable energy sources?

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

In the twentieth - century, people depend on unlimited energy to power their everyday lives. A wide range of energy-run devices and modern conveniences are taken for granted, and although it may seem that we will never be in danger of living without those conveniences, the fact is that many supplies of energy are dwindling rapidly. Scientists are constantly searching for new sources of power to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend on the success of this search.

Coal, oil, and natural gas supply modern civilization with most of its power. However, not only are supplies of these fuels limited, but they are a major source of pollution. If the energy demands of the future are to be met without seriously harming the environment, existing alternative energy sources must be improved or further explored and developed. These include nuclear, water, solar, wind, and geothermal power, as well as energy from new, nonpolluting types of fuels. Each of these alternatives, however, has advantages and disadvantages.

Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they pose the daunting problem of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities located far from moving water. Harnessing energy from tides and waves has similar drawbacks. Solar power holds great promise for the future but methods of collecting and concentrating sunlight are as yet inefficient, as are methods of harnessing wind power.

Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resources, such as a combination of solar, water, wind, and geothermal energy and alternative fuels, such as alcohol and hydrogen, will ensure supplies of clean, affordable energy for humanity's future. 

Which of the following can be inferred from the passage? 

A. Our present energy sources must be eliminated and replaced with alternative sources. 

B. Demands for energy in the future are likely to decrease

C. The search for alternative energy sources is not over

D. Alternative sources of energy on this planet are very limited
