Find 7 mistakes in the paragraph and correct them:

Alternative sources of energy


In the " Search for Free Energy", Tutt's recently released book, he quotes " We ought to be able to obtain the energy we need without the consumption of material." These are not the words of some modern-day environmentalist, but of Nikola Tesla, in 1890. Among his invention was the device to generate electricity by harnessing "coming energy". The search for free, and expensive energy continues. Researchers are looking for "fuelless" technologies that will not pollute or run out, and they are not referring to the puny contribution of solar or wind power. The science establishment has so far been proven correct, there's no such thing as a free energy lunch but that hasn't stopped mad scientists trying. They've come up with numerable patents of "over unity" contraptions, supposed giving out more energy than you put in to get them going. The story is fascinating and rarely heavy-going, although the quotes can be overlong and the diagrams are adequately displayed. Tutt admits that only a fraction of what is claimed is true. But it's also true to say we cannot afford to dismiss them out of hand, as one of these conforming investigators may just be able to save our planet from climate change.

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.
1. Which is the best title of the passage?
A. Efficient Ways of Disposing of Waste B. The Use of Water Productions for
Energy
C. The Search for Alternative Sources of Energy D. New Discoveries in Geothermal Power
2. In the second paragraph, the phrase “synthetic fuels” could best be replaced by which of
the following?
A. Biological fuels B. Low burning fuels C. Fast burning fuels D. Artificial
made fuels

sources of energy is due to ___________ .
A. their being time consuming B. their being money consuming

C. the scarcity of sources D. the lack of technology their being
money consuming
5. The word “it” in the last paragrph refers to ____.
