I'm taking a test and have to guess the right answer to the question after the article. Article: Can you speak to dolphins? Of course you can but you won't be able to understand them! We interviewed a biologist and asked her what research on dolphin communication has shown. This is what she told us. Just like dogs, cats and other mammals, dolphins communicate by using sound, vision , touch and taste. Each dolphin has its own signature whistle to identify itself and to call others. Dolphins don't have the ability to smell, but their hearing and eyesight are excellent. We also asked Jane if dolphins have got their own language. She told us that they have and that dolphins started talking to each other from birth. They make different sounds, including whistles, squeaks and click. Sometimes they even sound like a heavy metal band! We then asked Jane if any interesting experiments have been done. She told us that a very interesting experiment had been done with a mother dolphin and her two-year-old baby in an aquarium. They talked to each other over the telephone! The two dolphins were in separate tanks which were connected by a special under water system. Unfortunately the biologists couldn't understand what the dolphins were talking about because they haven't been able to decode dolphin language yet. However, it was very clear that the dolphins knew what they were talking about. Finally we asked Jane if there was hope that we would be able to understand dolphins in the near future. She told us that she and her team have been listening to dolphins for more than 17 years, using special equipment to record and analyze their language. Unfortunately they haven't been able to decode it yet, but who knows -- maybe one day we'll get a phone call from a dolphin. Question: The word "analyze" in the reading mean _ . Options: A: use B: translate C: copy D: study

I'm taking a test and have to guess the right answer to the question after the article. Article: Passage 3 A smile will tell people around you that you are a kind and friendly person. However, many people don't smile because they think they have ugly teeth. For example, one of my classmates, Mike, doesn't have very nice teeth, so that is why he seldom opens his mouth. He even says that he has lost confidence because of his teeth. So it is very important for us to look after our teeth. In fact, a lot of people have this problem. Some people inherit teeth problems from their parents, while others' teeth are damaged because of bad habits, like heavy smoking, eating too much sugar or not brushing teeth often. If your teeth are in bad shape, you should see a dentist and ask for help. They can help improve your teeth and tell you how to take care of them. Smiling can help you to feel more confidence and make people think of you as a more friendly person. If you want to keep healthy, you should not only smile but also laugh. An Indian doctor called Kataria said that young children should laugh about 30 times a day, while adults should laugh between 7 and 15 times a day. So please take this chance to smile and laugh now. Question: What has made Mike lose his confidence? Options: A: His bad habit B: His bad teeth C: Not smiling D: Eating too much sugar
