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.

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.

  It’s a sound you will probably never hear, a sickened tree sending out a distress signal. But a group of scientists has heard the cries, and they think some insects also hear the trees and are drawn to them like vulture to a dying animal. Researchers with the US Department of Agriculture’s Forest Service fastened sensors to the bark of drought-stricken trees clearly heard distress calls. According to one of the scientists, most parched trees transmit their plight in the 50-hertz to 50kilohertz range. (The unaided human ear can detect no more than 20 kilohertz). Red oak, maple, white pine, and birch all make slightly different sounds in the form of vibrations at the surface of the wood.

 

   The scientists think that the vibrations are created when the water columns inside tubes that run along the length of the tree break, a result of too little water following through them.

 

   These fractured columns send out distinctive vibration patterns. Because some insects communicate at ultrasonic frequencies, they may pick up the trees' vibration and attack the weakened trees. Researchers are now running tests with potted trees that have been deprived of water to see if the sound is what attracts the insects. “Water-stressed trees also smell differently from other trees, and they experience thermal changes, so insects could be responding to something other than sound”, one scientist said.

Question: All the following are mentioned as possible factors in drawing insects to weakened trees EXCEPT______.

A. thermal changes

B. sounds

C. changes in color

D. smells
