Read the article and select the best answer. Article: Ears are for hearing -- everyone knows that. But for a creature called the Cuvier's beaked whale, hearing starts in the throat, a new study found. The observation might help explain how all whales hear. The work might also help scientists understand how animals are affected by underwater sonar . This sonar, used by some ships, sends out sound waves to locate underwater objects. The Cuvier's beaked whale is a so-called toothed whale. Toothed whales dive deep into the ocean in search of food. As the whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to "see" the shape, size, and location of objects, even when they're 1,000 meters under the sea, where it is totally dark. To better understand how the whale hears, researchers from San Diego State University in California took X-rays of two Cuvier's beaked whales. The whales had died and washed up on the beach. Ted Cranford and his colleagues used the images to make a computer model of a Cuvier's beaked whale's head. Then, they modeled the process of sound traveling through the head. The researchers knew that some sounds get to the ears of a toothed whale through a structure called "the window for sound". Found on the lower jaw, this structure is very thin on the outside and has a large pad of fat on the inside. When the researchers used their computer model to work out how sound waves travel in the whale's head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal's jaw. From there, sound waves move through the throat, into a hole in the back of the jaw, and finally to the pad of fat near the animal's ears. Cranford guesses that other types of whales may hear through their throats. Further testing is needed to be sure. Eventually, the insight into how whales hear might explain whether sonar testing by military ships is causing the animals to wind up on beaches. Question: Which of the following describes the way taken by sound waves through a Cuvier's beaked whale? Options: A: A hole in the back of the jaw - the ears - the jaw - the throat. B: The jaw - the throat - a hole in the back of the jaw - the ears. C: The throat - the jaw - the ears - a hole in the back of the jaw. D: The ears - the throat - a hole in the back of the jaw - the jaw.

Read the article and select the best answer. Article: What is your body language saying to your children? What is their body language telling you? I had the honor of hearing Jan Hargrave speak the other day. She is one of four body language experts in the US. Jan Hargrave says we lie with the right side of our brains, so it is our left hand that gives us away. A person touching his nose, pulling at his ear or rubbing his eye with his left hand might be lying to you. Also, a person who, in any way, crosses any fingers might just be lying. That, she says, is a holdover from childhood, when we crossed our fingers to signal that we didn't mean what we were saying. When children squint their eyes, move their body away from you, or can't seem to make good eye contact, you may need to ask for a little more clarification. But just as important, children learn early how to read our body language when they are conversing with us. Here are some acceptance signals to let them know you are interested when they are talking to you. Lean towards them. Make good eye contact and smile. Open your arms. Let your hands relax with the palms showing: an open, upward palm always show acceptance. If your legs are crossed, make sure you are not crossing them away from your child. These are important because they signal to your child that you are focused on them and are accepting and welcoming them into your world. By paying attention, we can open those lines of important communication with our children and we can see the truth more clearly. I think it would be a mistake to use these tools to lie, but we need to be aware of the signals we are giving so we can show people that they really do matter to us. Question: We can learn from the passage that body language _ . Options: A: is hard to master for children B: can be understood in different ways C: may help improve communication D: is more likely to hide the truth

Read the article and select the best answer. Article: Renault's new Twizy could be the future of motoring ... or at least a big part of it. This is not some crazy future concept -- this is a real vehicle, fully electric, and on sale now. Prices for the Twizy start at PS6,690, with battery hire from PS45 a month. But is it a car? Technically no, it' s classified under UK law as something closer to a moped . A two-seater (the passenger sits behind the driver), the Twizy runs on electric power only, and is designed to cover all those little trips we do. And as 87 percent of Europe's drivers do less than 37 miles a day -- 50 per cent less than 12--there's really no need to be burning gas for that sort of journey. The Twizy is arguably the most unusual vehicle in this country. Other cars have been beautifully designed, others have been small, but no car has turned motoring on its head in quite the same way. The Twizy's batteries have a range of 62 miles, and it plugs into a standard socket like any other electrical equipment, going from flat to full power in three and a half hours. There are no full doors on the vehicle, so think of it like a covered moped with four wheels, but no noise and no need for a helmet. There's also a lower-powered type being designed, the Twizy 45, for which you don' t need a license. Seeing the Twizy in the flesh, you' re surprised by how striking it looks. Sit in it and everything feels right --just car enough to be easy, but different enough to be exciting. With the battery underneath you, the vehicle is suckered to the road, and the electric power means it accelerates with real energy up to about 50 mph. You don't feel you need any more. In the UK, the weather alone may make it a good buy, but the lack of easy access to outdoor sockets is the biggest challenge. Only time will tell if this brave move answers enough problems to find a place in our lives. Question: In which part of a magazine can we most probably read this text? Options: A: Travel. B: Technology. C: Economy. D: Environment.
