Article: On May 23,1989, Stefania Follini came out from a cave at Carlsbad, New Mexico. She hadn't seen the sun for eighteen and a half weeks. Stefania was in a research program, and the scientists in the program were studying body rhythms . In this experiment Stefania had spent 130 days in a cave, 30 feet in depth. During her time in the cave, Stefania had been completely alone except for two white mice. Her living place had been very comfortable, but there had been nothing to fell her the time. She'd had no clock or watches, no television or radio. There had been no natural light and the temperature had always been kept at 21degC. The results were very interesting. Stefania had been in the cave for over four months, but she thought she had been there for only two. Her body clock had changed. She hadn't kept to a 24-hour day. She had stayed awake for 20-25 hours and then had slept for 10 hours. She had eaten fewer meals and had lost 17lbs in weight as a result! She had also become rather depressed . How had she spent her time in the cave? As part of the experiment she'd done some physical and mental tests. She'd recorded her daily activities and the results of the tests on a computer. This computer had been specially programmed for the project. Whenever she was free, she'd played cards, read books and listened to music. She'd also learned French from tapes. The experiment showed that our body clocks are affected by light and temperature, For example, the pattern of day and night makes us wake up and go to sleep. However, People are affected in different ways. Some people wake up naturally at 5:00 am, but others don't start to wake up till 9:00 or 10;00 am. This affects the whole daily rhythm. As a result, the early risers are at their best in the late morning. The late risers, on the other hand, are tired during the day and only come to life in the afternoon or evening! Question: Where does the text probably come from? Yes or no, is the answer "A news story"?
**Answer**
No

Article: Have you ever had a day when everything seemed to go wrong, and nothing seemed to go right? Not too long ago I was having one of those days. I was discouraged, weary, and plain sad. My focus was on me. After all, no one else was experiencing the same trials I was. I expressed my upset state to my mother, hoping for some pity. Instead, she said, "I heard Jamie was having a difficult day too. Why don't you make her some cookies and take them to her this afternoon?" I didn't really want to, but decided that I didn't want to go back to my other problems just yet. I made the cookies and arranged them on a little plate. Then I made a card with a sunflower on it and wrote a small note of empathy. That afternoon I dropped by my friend's house. I went to the door and rang the bell. Soon, Jamie came to the door and looked at me in surprise for the unexpected visit. Before she could say anything I rushed, " I heard you were having a hard day and decided to bring you something. I hope your day goes better." The look that came over Jamie's face was one that I could never put into words. It was as if a darkened sky was suddenly lit with the golden rays of the sun; it was as if in that small act, her day was brightened. I got back into the car and for some amazing reason; I felt a lot better myself. That day I experienced the truth that James Barri attempted to describe, " Those who bring sunshine to the lives of others cannot keep it from themselves." Question: What do you think of the author's mother? Yes or no, is the answer "Instructional."?
**Answer**
Yes

Article: LONDON (Reuters)--New faces given to a Chinese man after a bear tore off part of his face and a FrenchCaribbean man disfigured by a rare tumor show that such transplants can work and are not medical oddities ,researchers said. The findings give hope to some people with severe facial disfigurement and suggest the transplants could prove longlasting without major problems.Despite the tissue rejection in the first year after their transplants,neither men had psychological problems accepting their new faces and have been able to rejoin society,they reported. Only three people have received face transplants.The world's first was carried out on French woman Isabelle Dinoire in November 2005 after she was disfigured in an attack by her dog.In 2007,her doctors reported that she had recovered slowly and steadily,overcoming two periods of rejection. In 2006,Chinese doctors performed a face transplant on a 30yearold hit by a bear.While there were some complications with tissue rejection following the operation,two years later the man was doing well,his doctors said."This case suggests that facial transplantation might be an option for _ a severely disfigured face,and could enable patients to bring themselves back into society," Shuzhong Guo and colleagues at Xijing Hospital in China wrote. A French team described their work on a 29yearold man who suffered from Von Recklinghausen disease,an illness that changes the shape of his face."The man,who was not named,was given a new nose,mouth and chin in a 2007 operation.He began to work 13 months after the transplant has more function in his face and has not rejected the new tissue," his doctors said. "Our case confirms that face transplantation is practical and effective for the correction of specific disfigurement," Dr.Laurent Lantieri and colleagues at the HenriMondor hospital outside Paris wrote. Question: What problem resulted from the facial operations? Yes or no, is the answer "The patients usually suffered from tissue rejection."?
**Answer**
No

Article: Many of us use them several times a day without really noticing.And yet the way we in lifts,or elevators as they are known in the US,reveals a hidden anxiety. Passengers seem to know instinctively how to arrange themselves in an elevator,like the dots on a die.With each additional passenger, the bodies shift,going into the open spaces. On your own,you can do whatever you want--it's your own little box.If there are two of you,you take different corners, creating the greatest distance. When a third person enters, you will unconsciously form a triangle .And when there is a square, with someone I every corner.A fifth person is probable going to have to stand in the middle. Why are we so awkward in lifts? "You don't have enough space," says Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin."Usually when we meet other people we have about an arm's length of distance between us. And that's not possible in most elevators, so it's a very unusual setting. It's unnatural." But perhaps there is more to it than just social awkwardness. "In the back of our minds we are a little anxious," says Nick White,an office in New York who was unfortunate enough to be trapped in a lift for41 hours. "We don't like to be locked into a place.We want to get out of the elevator as soon as possible, you know, it's a frightening place to be." During his terrible experience, he began to think of another encloses space-a tomb. Dr.Lee Gray agrees that a sense of disempowerment is the main cause of life anxiety. "You're in a machine that's moving, over which you have no control. You cannot see the elevator engine, you don't know how it's working," he says. Question: What does the text mainly talk about? Yes or no, is the answer "People's behavior in lifts."?

No
