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 from 39 to 43.
Jack McDougal - a 15-year-old high school student - set up a company with his dad three months ago. It's called Sun Mower and it's been a huge success for Jack. His grass-cutting equipment is powered by hi-tech batteries, which are recharged from solar panels. By replacing petrol with energy from the sun, Jack is also reducing air pollution and fighting global warming.
A school science project gave him the idea. “Our teacher asked us to think of ways in which we could make changes at home that would reduce our carbon footprint. We had recently had solar panels installed at home, and that gave me the idea.”
What if someone hasn't got a battery-powered lawnmower and solar panels at home? Jack says that's not a problem. “You can use an old-fashioned push mower instead of a petrol- powered mower. There are lots of easy things you can do to reduce pollution, clean up the atmosphere and fight global warming.”
Jack's idea has really taken off. More and more people in his area want him to mow their lawns using his Sun Mower. Jack said, “It's great that my business is successful, but it's even better that people are serious about improving the environment.”
