Read the following article and select the best answer. Article: Moral science is taught as a subject in most schools but with little effect. Perhaps part of the problem lies in the fact that morality is not a science, strictly speaking. It is too much of a social phenomenon, and also has too much of the personal and subjective things mixed within. Besides, morality itself changes with generations. So it is impossible to be defined in a textbook. I remember sitting through forty minutes of moral lessons, which told stories about little children who never told lies and were rewarded for their goodness. It had little effect and left no impression on me, though. If moral science has to be taught as a subject in schools, it needs a participatory approach. When you tell a child about morals, you also have to deal with social norms and cultural differences. You have to explain that morality can be subjective, and be able to co-exist in society. You will probably have to refer to the morals of the present time. The best way to tell a child how to live is to show him what is valued. If a child likes his friend, you have to make the child think about why. Once the child notices and recognizes goodness in others, he or she is likely to develop it as well. In fact, children learn most of their morals by watching people around them. They absorb behavior patterns from teachers and older students. They watch to see what is rewarded and who is punished. They learn on the sports field and through social work. Moral science lessons should simply consist of letting them live and interact, and watch you support correct values and reward good behavior. Question: Which is NOT the reason that moral science is taught in schools but with little effect? - Morality doesn't strictly belong to a science - Morality is more like a social phenomenon. - Different generations have different moral ideas. - Morality can't be written down in textbooks.
Morality can't be written down in textbooks.

Read the following 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: Toothed whales look for food under the sea by _ . - watching the shape and size of their objects - diving deep into the sea - sending and receiving sounds - making lots of noises
(Answer)
sending and receiving sounds

Read the following article and select the best answer. Article: Music is really powerful. Without music, movies would lose some of their attraction. No one disagree with the powerful effect music has on individuals. Whether this effect is positive or negative, however, often depends on the type of music listened to. And researches have shown that certain types of music own the ability to relieve one's anxiety, improve brain development in children, uplift one's memory and help patients to recover...just to name a few. It should come as no surprise then, that researchers from the Tufts University have found that background music has the ability to directly affect one's eating habits as well. They counted the bites of food individuals took at meals while listening to different types of music. The diners "ate at an average rate of 3.9 bites per minute", with about a third of the diners requesting more food after clearing their plates. On the other hand, with "spirited tunes, "the diners "sped up to an average of 5.1 bites per minute! "Not surprising however, when "calming flute instrumental" were played, the eating speed of the diners slowed "to 3.2 bites per minute--and the bites became smaller". They didn't request second helpings and praised that the food tasted better. Studies have clearly stated that one safe way of losing weight includes eating slowly. Since it takes about 20 minutes for your stomach to tell the brain that it's full, eating slowly will help you to eat to satisfaction--without overdoing it. With this important piece of information then, it leads one to believe that with the use of calming background instrumental music, one can slow their food digestion, "retraining" both the stomach and the brain to take in less food which could lead to weight lost. Is there any truth to this theory? One will never know unless they try it themselves. Even if it doesn't work for you, at least you'll achieve a bit of relaxing and pleasant environment during your meal periods. A great meal with great music--who could ask for anything more? Question: Which of the following statements agrees with the writer's view in the passage? - People will eat less if they don't like the background music. - Every type o f music has the power to affect people positively. - Most of the restaurants now offer background music for their customers. - Though we're not sure whether listening to music can help lose weight, it's worth a try.
