Article: Last Sunday, Aron Ralston, an experienced hiker and mountaineer, set off to walk alone through the Bluejohn desert canyon in Utah. He was planning an eight-hour, 21-kilometer hike. While he was climbing through a narrow part of the canyon, a big stone weighing about 400 kilos fell and trapped his right arm. When he failed to return to the mountain camp where he was staying that night, people simply thought he had decided to camp out somewhere in the canyon. When he still had not returned by Tuesday, the alarm was raised, A search party set out on Wednesday evening, but there we no sign and his family began to fear the worst. In fact, Ralston, 27, was lying trapped in the canyon. By Tuesday, he had run out of water. By Thursday, he realized that he would not survive unless he took unusual action, so he used his pocket knife to cut his arm below the elbow . He then climbed down to the bottom of the canyon. There he met two other hikers, who helped him back to safety. He received some help at a local hospital before being carried to St. Mary's hospital in Grand Junction, Colorado for surgery. Ralston's astonishing survival brought equal amounts of praise and criticism. While praising the climber for his bravery and calm, experts also pointed out he had broken the first rule of outdoor pursuits. He had failed to leave words with anyone of where he was going that day. This was in fact Ralston's second near-death experience. In February, he was buried up to the neck in snow by an avalanche while skiing in the Colorado Rockies. Ralston not only managed to dig himself out but he also rescued his skiing companion, who had been completely buried in the snow. Ralton rescued himself and his friend in less than 15 minutes.

Article: "Where is Papa going with that ax ?" said Fern to her mother as they were setting the table for breakfast. "Out to the hoghouse," replied Mrs. Arable. "Some pigs were born last night." "I don't see why he needs an ax," continued Fern, who was only eight. "Well," said her mother, "one of the pigs is a runt . It's very small and weak. So your father has decided to do away with it." "Do away with it?" shouted Fern. "You mean kill it?" "Don't shout, Fern!" she said. "Your father is right. The pig would probably die anyway." Fern pushed a chair out of the way and ran outdoors. The grass was wet and the earth smelled springtime. Fern's shoes were wetting by the time she caught up with her father. "Please don't kill it! It's unfair," she said. Mr. Arable stopped. "Fern," he said gently, "you will have to learn to control yourself." "This is a matter of life and death, and you talk about controlling myself." Tears ran down her cheeks and she took hold of the ax and tried to pull it out of her father's hand. "Fern," said Mr. Arable, "I know more about raising a group of pigs than you do. A weak pig makes trouble." "But it's unfair," cried Fern. "The pig couldn't help being born small. If I had been very small at birth, would you have killed me?" Mr. Arable smiled. "Certainly not," he said, looking down at his daughter with love. "But this is different. It's a pig." "There is no difference," replied Fern. Question: Why couldn't Fern control herself? Yes or no, is the answer "Because the pig was treated unfairly."?

Article: An American spacecraft is moving closer to a dwarf planet called Ceres . The American space agency's Dawn spacecraft is set to reach the planet-like object in March. Space agency scientists will then place Dawn in an orbit around the dwarf planet. Agency scientists want to know more about ice on Ceres. The spacecraft will gather clues about whether Ceres may have once had conditions to support life as we know it. Dawn left Earth more than seven years ago on a trip to explore Ceres and another dwarf planet, called Vesta . Both dwarf planets are in the main belt of asteroids , a group of large objects, between the planets Mars and Jupiter. Marc Rayman is the chief engineer and director of the Dawn mission. Scientists call Vesta and Ceres "protoplanets ". Mr. Rayman says they were in the process of becoming full-size planets when, in his words, "their growth was terminated ." Scientists believe Ceres is made of rock, and covered with ice. The Dawn mission is based in Los Angeles, California. Scientists there send second-by-second commands to the spacecraft. They direct its every move, including telling it what pictures to take. Dawn will make a map of the dwarf planet. It will also try to discover how Ceres' surface has changed. Carol Raymond is the deputy principal investigator of the project. He says Dawn made an unexpected discovery while orbiting Vesta. "Instead of being bone dry, which we expected, there were _ on the surface of Vesta that showed significant amounts of water bound in the rocks and possibly even free water that could have flowed on the surface in the past." She says that if Earth's water came from wet worlds like Vesta and Ceres, then life could have developed there, too. If Dawn finds that the environment of Ceres could have supported life, scientists may seek to explore the dwarf planet with other scientific instruments. Dawn will gather information about Ceres until the middle of 2016. It will then continue to orbit the small planet. Question: The passage mainly tells us _ . Yes or no, is the answer "NASA Spacecraft, Dawn, is moving closer to a 'Dwarf Planet'."?
