Read the following passage and make the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions from 41 to 48.Scientists have discovered the bones of what may be the largest meat-eating dinosaur ever to walk the earth. The discovery was made by a team of researchers from Argentina and North America in Patagonia, a desert on the eastern slopes of the Andes in South America. Besides the interesting fact that the dinosaur was huge and horrifying, it is even more astounding that the bones of a number of the dinosaurs were found together. This discovery challenges the prior theory that the biggest meat-eaters lived as loners and instead indicates that they may have lived and hunted in packs. The Tyrannosaurus Rex lived in North America and was believed to hunt and live alone.The newly discovered meat-eater appears to be related to the Giganotosaurus family, being as closely related to it as a fox would be to a dog. It is actually not of the same family at all as the Tyrannosaurus Rex, being as different from it as a cat is from a dog.The fossilized remains indicate that the animals lived about 100 million years ago. With needle-shaped noses and razor sharp teeth, they were larger than the Tyrannosaurus Rex, although their legs were slightly shorter, and their jaws were designed to be better able to dissect their prey quickly and precisely.Read the following passage and make the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions from 41 to 48.Scientists have discovered the bones of what may be the largest meat-eating dinosaur ever to walk the earth.

The ancient Romans and Egyptians made candles from a type of fiber coated with wax. However, up until the nineteenth century, most candles were made from a substance called tallow, obtained from beef fat. Tallow candles were very smoky and, understandably, had an unpleasant odor. In the 19th century, candle makers learned to separate stearin, the solid form fat used as a type of glue, from tallow and used it to harden other fats. Candles that contained stearin would burn longer than previous ones and had a better smell. Stearin is still one of the main components of modern candle-making, and the techniques used to create candles today are much the same as they have been for many years. These days, the increase range of wax dyes, perfumes and other additives that are now available make candle making a very exciting and rewarding hobby. Sales of candles have increased greatly over the last few years, showing that they have become part of our lives again, not through necessity, but because of the magical atmosphere they create. In our increasingly stressful lives, the calming quality of candlelight has a relaxing effect that many enjoy. For those would like to learn to make candles, finding and buying candle-making kits is easy. Candle-making is definitely enhanced by the exciting possibilities of experimentation with various materials. Be brave and try out different effects – some of the most wonderful creations can happen by accident. With a bit of practice, you will be amazed at the very professional finish that can be achieved. Despite their delicate beauty, candles can, of course, be highly dangerous. One should never leave lit candles unattended, even for a few moments. Always make sure candles are securely placed within candleholders. Teach your children to respect a burning candle, and of course keep burning candles away from flammable materials. Keep your home safe by remembering that a candle is magical, but fire can be very destructive. Be careful, and enjoy the beauty of your candles!Which of the following best expresses the main idea of this passage?
