Article: The crowd at the airport flowed forward. The passengers had been waiting for a couple of hours for an airline employee to open the door leading to the plane outside. No one was in a good mood. An old man got trapped in the middle of the rush. He fell down without being able to break his fall. His head hit the concrete floor. Blood poured from his forehead. He appeared to be unconscious. Everyone rushed past him, except Dana. She called for help. A minute later, a young airline employee showed up. Hardly looking at the old man, she told Dana to get aboard her plane. She said the old man would be okay, and walked away. Dana screamed for help. An airport supervisor appeared. He told Dana to get on the plane. Dana said that she was not moving until an ambulance arrived. The supervisor said her plane would leave without her. Dana said that she didn't care. An ambulance and two attendants finally arrived. The attendants said that the man would be okay, but he would need stitches . They put him into the ambulance and drove off. On her way out to the plane, which was still refueling, Dana saw the employee who had ignored the old man at first. The employee said, "You're lucky. The plane didn't leave without you." "The plane?" Dana asked. "Who cares about the plane? How could you be so cold? That was an old man; he could have been your grandfather! How would you like it if everyone just stepped over your grandfather and went on their way?" Question: What does the story mainly tell us about Dana? Yes or no, is the answer "She was the only person who helped the old man."?
No

Article: Thousands of dead red-winged blackbirds fell from the sky in an Arkansas town on New Year's Eve after massive injuries, tests by Arkansas officials concluded on Monday. Some 5,000 birds mysteriously fell from the sky in Beebe, Arkansas after dark on New Year's Eve. "The birds suffered from acute physical injuries leading to internal hemorrhage and death. There was no sign of infectious disease," the Arkansas Game and Fish Commission said in a statement. The birds were otherwise healthy, it said. One theory is that birds were frightened by New Year's fireworks and flew into buildings or other objects. "Loud noises were reported shortly before the birds began to fall from the sky," the statement said, adding that blackbirds have poor night vision and seldom fly at night. Another theory was that severe weather such as lightning accounted for the loud noises but this was _ because the violent weather had already left the area. "We're leaning more toward a stress event," said Arkansas Game and Fish Commission spokesman Keith Stephens. The commission also is trying to determine what caused the deaths of up to 100,000 fish over a 20-mile stretch of the Arkansas River near a dam in Ozark, 125 miles west of Beebe. The fish were discovered on December 30. Stephens said the commission expected results on the fish tests in probably a month. Since almost all the fish were one species -- bottom-feeding drum, Stephens said, the test was very important. Stephens also said: "The events do not appear related." Both that section of the river and the air at the site of the bird deaths were tested for toxins . Beebe is a town of about 4,500 people located 30 miles northeast of the state capital. Question: The passage is mainly developed by _ . Yes or no, is the answer "analyzing causes"?
No

Q: Article: While residents of wealthy nations tend to have greater life satisfaction, new research shows that those living in poorer nations report having greater meaning in life. These findings, published in Psychological Science, a journal of the Association for Psychological science, suggest that meaning in life may be higher in poorer nations as a result of greater religiosity . As countries become richer, religion becomes less central to people's lives and they lose a sense of meaning in life. "Thus far, the wealth of nations has been almost always associated with longevity, health, happiness or life satisfaction," explains psychological scientist Shigehiro Oishi of the University of Virginia. "Given that meaning in life is an important aspect of overall well-being, we wanted to look more carefully at differential patterns, correlates , and predictors for meaning in life." Oishi and colleague Ed Diener of the University of Illinois at Urbana-Champaign investigated life satisfaction, meaning, and well-being by examining data from the 2007 Gallup World Poll, a large-scale survey of over 140,000 participants from 132 countries. In addition to answering a basic life satisfaction question, participants were asked: "Do you feel your life has an important purpose or meaning?" and "Is religion an important part of your daily life?" The data revealed some unexpected trends: "Among Americans, those who are high in life satisfaction are also high in meaning in life," says Oishi. "But when we looked at the societal level of analysis, we found a completely different pattern of the association between meaning in life and life satisfaction." When looking across many countries, Oishi and Diener found that people in wealthier nations were more educated, had fewer children, and expressed more individualistic attitudes compared to those in poorer countries - all factors that were associated with higher life satisfaction but a significantly lower sense of meaning in life." The data suggest that religiosity may play an important... Question: What can be inferred from the passage? Yes or no, is the answer "Meaning in life doesn't have much to do with the amount of wealth one possesses."?
A: No

Article: There is an endless supply of stories about sleepwalkers . People have been said to climb on roofs, solve mathematical problems, write music, walk through windows, and do murder in their sleep. In Revere, Massachusetts, a hundred policemen searched for a lost boy who left his home in his sleep and woke up five hours later on a strange sofa in a strange living room, with no idea how he had got there. At the University of Lowa, a student was reported to have the habit of getting up in the middle of the night and walking three-quarters of a mile to the Lowa River. He would take a swim and then go back to his room to bed. An American expert on sleep claims that he has never seen a sleepwalker. He is said to know more about sleep than any other living man, and during the last thirty-five years he has lost a lot of sleep watching people sleep. He says, "Of course, I know that there are sleepwalkers because I have read about them in the newspapers. But none of my sleepers ever walked, and if I were to advertise for sleepwalkers for an experiment, I doubt whether I would get many takers ." Sleepwalking, however, is a scientific reality. It is one of those strange things that sometimes look quite fantastic . Doctors say that sleepwalking is much more common than is generally supposed. Many sleepwalkers do not try to find help and their sleepwalking is never recorded. Question: Generally speaking, sleepwalkers are people who _ . Yes or no, is the answer "do fantastic things during their sleep"?
No
