Q: Article: Many people say dolphins are very intelligent. They seem to be able think, understand, and learn things quickly. But they are smart like humans or more like cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are alike in some ways. How? FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins? Why do they assist the men? The dolphins get to eat some of the fish.

Options: (A) The comparison between dolphins and humans. (B) The relationship between dolphins and humans. (C) Different types of dolphins. (D) The habitual behavior of dolphins.

Q: Article: A 16-year-old South Dakota boy who became lost while hunting and spent 16 hours alone in the Black Hills National Forest says he was scared but still managed to make a survival plan. Austin DuVall, of Rapid City, became lost on Nov.3 while hunting with his father. He ran after a deer, and soon found himself alone. "I ran after a deer, but I didn't get it," he said. "Then I was really lost." He had only his hunting rifle and the clothes he was wearing. He had no food or water and had nothing that could help him find his way to safety. "I knew that no one could hear me. I decided to just sleep and get up in the morning and find safety," he said. Austin climbed up on a rock and slept through the night. Then he awoke and relied on skills he learned in a hunter safety course. He followed a stream to an occupied cabin. The couple there called his parents and cooked him a breakfast. " It's probably one meal I'll never forget for the rest of my life," he said. After DuVall's disappearance, a lot of emergency officials and more than 100 volunteers went searching for him. "He wasn't sitting there waiting for someone to come and find him," said his father, Steve DuVall. "We didn't find him; he found himself." Mike Kintigh, regional supervisor for the Game, Fish & Parks Department, said one or two hunters will go missing each year, but rarely for more than 24 hours. "We're a little bit unique in the Black Hills as it's hard to get lost for a very long time. That's because we've got so many roads here compared to the Rocky Mountains," Kintigh said. "You can certainly spend a very uncomfortable night in the woods like Austin did."
Question: After Austin realized he lost his way, he _ .
Options: (A) was very nervous but excited (B) cried aloud for help (C) tried to find a safe place (D) decided to sleep in the wild
