Dolphins live in a dark underwater world. It's often impossible to see each other or anything else around them, so sound plays an important role in their survival. To communicate with each other, dolphins produce all kinds of sounds. Only other dolphins understand what the sounds mean. Scientists haven't uncovered their secret communication, except for one kind of whistle. It might last less than a second, but this whistle is a big deal. Why? Because these whistles are actually names of dolphins - and every dolphin has one. Scientists call these sounds a "signature whistle." When other dolphins hear the whistle, they know which dolphin is calling. Dolphins often hunt by themselves but still need to stay connected to the group. Since they can't always see each other, dolphins use their signature whistles to check in with other dolphins hundreds of yards away. "In coastal areas, dolphins exchange whistles even when they're a third of a mile apart," says Greg Campbell, who studies animals. That means dolphins shout out to group members that might be nearly five football fields away. What's amazing is who names the baby dolphin. Not the mother. Not an auntie dolphin or another group member. Scientists believe the baby dolphin itself comes up with the signature whistle. Like human babies, a baby dolphin plays with sounds throughout its first year. While testing its sound skills, a baby dolphin is doing something amazing. It's creating or figuring out its signature whistle. How or why it chooses its signature whistle is not clear. Studies show that most of the time the signature whistle is nothing like its mother's or group members' whistles. When the baby dolphin is about a year old, its signature whistle is set. It repeats it often so the other dolphins learn to recognize it. Deciphering dolphin names is just the beginning of figuring out what dolphins communicate about. Do they chat about sharks? Discuss the tides? Maybe they even have a name for people. Someday scientists are to decipher the rest of dolphins'... A baby dolphin gets its name _ . A) soon after it was born B) according to its size C) all by itself D) with the help of its group

A butcher watching over his shop was really surprised when he saw a dog coming inside the shop. He went over to the dog and noticed it had a note in its mouth. He took the note and it read "Can I have 12 sausages and a leg of lamb, please. The dog has money in his mouth, as well." The butcher looked carefully and was surprised to find that there was really a ten-dollar note there. So he took the money and put the sausages and lamb in a bag, placing it in the dog's mouth. The butcher was so impressed, and since it was about closing time, he decided to shut up shop and follow the dog. So off he went. He followed the dog to a bus stop. The dog stopped and started looking at the timetable. The dog checked out the time, and then sat on one of the seats provided. Along came a bus. The dog walked around to the front, looked at the number, and went back to its seat. Another bus came. Again the dog went around to the front, looked at the number and climbed on. The butcher, by now, open-mouthed, followed it onto the bus. The bus traveled through the town and out into the suburbs. Eventually the dog got up, and moved to the front of the bus. It stood on two back paws and pushed the button to stop the bus. Then it got off with groceries still in its mouth. Well, the dog and the butcher were walking along the road, and then the dog turned into a house. It walked up the path, and dropped the groceries on the step. Then it walked back down the path, took a big run, and threw itself against the door. Then again, it threw himself against it. There's no answer at the house. so the dog waited at the door. The butcher watched as a big guy opened the door, and started shouting at it. The butcher ran up, and stopped the guy. "Why do you shout at the dog? It is really a genius." The guy responded, "You call this clever? This is the second time this week that this stupid dog's forgotten its key." Which of the following statements is NOT true? A) The butcher was curious so he followed the dog. B) The dog didn't get on the first bus because it was the wrong number. C) To get off the bus, you should let the driver know by pressing the button. D) The dog would be driven away by the big guy.
