Ques: There are new findings that not enough sleep may cause people to gain weight. Researchers say a lack of sleep can produce hormonal  changes that increase feelings of hunger. In one study, researchers in the United States examined information on more than 1000 people. The people had taken part in a long-term study of sleep disorders. Some people slept less than five hours a night. They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had 15 percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full. The scientists say these hormonal changes may be a cause of obesity in Western societies. They note the combination that sleep limitation is common and food is widely available. The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight. It seems that, for survival, the body may be designed to store more fat during times with less sleep. Researchers from Stanford University in California and the University of Wisconsin did the study. They found that the best amount of sleep for weight control is 7.7 hours a night.The Public Library of Science published the findings in its journal Medicine . Internet users can read the full study, free of charge, at plos. org. You can read the findings  _ A) Only on the Internet B) only in Medicine C) Both on the Internet and in Medicine D) Neither on the Internet nor in Medicine

Ques: About a year ago, a couple with three children moved into the apartment next door to mine. I never heard any noise from the children, but the parents were always yelling at the kids.     We often met in the hallway when we were coming or going. I always spoke, but the only answer I got was a "Hello" from the four-year-old girl.     One afternoon when I returned, they were just coming out of their apartment and the little girl was holding the door open for the others. I remained in the car doing unnecessary things. But when I looked up I saw the little girl was still holding the door open, waiting for me. I hurried as much as I could and thanked her.     I was really touched by her act of kindness. That afternoon I was at the K-Mart and I bought a white Teddy bear for her. The next day, there was a knock on the door and it was the little girl and her father. She was very proud of the bear and thanked me like I had never been thanked before.     Now when we meet in the hall, we all speak in a friendly manner. As time passes, I don't hear that yelling as often as before.     Last night we had about four inches of snow. I looked out at my car and wondered how I was going to keep my doctor's appointment. I went out to remove the snow. But when I opened my front door, I found my car was there with all the snow removed. You couldn't imagine how I felt at that moment. I thanked that family in my heart.     Isn't it amazing that a small kind act of a four-year-old girl could change so many things for the better? My guardian angel says that good things come from small acts. Which of the following is CORRECT according to the passage? A) The children were very naughty and often made their parents angry. B) Life must be very hard for the parents next door as they had a large family to support. C) The writer put off the appointment with his doctor because of the heavy snow. D) The little girl's kind act changed the relationship between the writer and her family.

Ques: School Report went international when the BBC News project's first global radio bulletin  was made at Randfontein High School in South Africa. Students from the school were joined by pupils from two other schools--Parktown High School for Girls and Impala Crescent Primary School--and went live  at 14:00 local time on 3 February, 2010. BBC producers Ros Smith and Kate Riley were invited to work with the schools. After deciding on their news topics, the students gathered vox pops from fellow students and their teachers. Tiffany said, "We had a chance to talk to other kids from other schools. This was great because Randfontein is a place which is not known to many people and away from modern civilization." Nomakhosi added, "Interviewing our teachers and classmates was interesting and I felt important while doing this." Chene commented, "My voice sounded like a whole new person. It takes some time to get used to hearing your own voice." Pupils, known as learners in South Africa, then worked with School Report producer Ros Smith to edit their audio  material while others started script-writhing . With the 14:00 deadline fast approaching, and the audio edited, the new School Reporters recorded their scripts so they could be added to the bulletin. Ros Smith was really impressed with the students' work. She said, "The stories they chose were an excellent mix. The final bulletin sounds really good, and they finished with 10 minutes to spare before the deadline." On 26 March students from the three schools took part in the School Report News Day with support from the Open Learning Systems Education Trust, and it was a big success. Which of the following is TRUE about Randfontein? A) It is a big city in South Africa B) it is a small and underdeveloped place C) it started the School Report News Day D) It invited Ros Smith and Kate Riley for a celebration
Ans: B

Ques: Watching bison up close is fascinating, like watching a grass fire about to leap out of control. With their huge, wedge-shaped heads and silver-dollar-size brown eyes, the 2,000-pound animals are symbols of another place and time. More than 100 bison now roam the 30,000-acre American Prairie Reserve in eastern Montana -- the first time they've inhabited that region in a century. Direct descendants of the tens of millions of bison that once populated the Western plains, they represent an epic effort: to restore a piece of America's prairie to the national grandeur that Lewis and Clark extolled two centuries ago. During that famous expedition across the Western states to the Pacific, the two explorers encountered so many bison that they had to wait hours for one herd to pass. In order to protect what's here and reintroduce long-gone wildlife (something the World Wildlife Fund is helping with), the American Prairie Foundation began purchasing land from local ranchers in 2004. It now owns 30,000 acres and has grazing privileges on another 57,000. Its goal over the next 25 years is to assemble three million acres, the largest area of land devoted to wildlife management in the continental United States. Already, herds of elk, deer, and pronghorn antelope roam the grasslands, where visitors can camp, hike, and bike. Cottonwoods and willows are thriving along streams, creating habitats for bobcats, beavers, and other animals. Not everyone shares APF's vision. Some residents of Phillips County (pop. 3,904) worry that the area could become a prairie Disneyland, overcrowded with tourists. But the biggest obstacle is the ranchers themselves, whose cattle compete with prairie dogs and bison for grass and space. "People like me have no intention of selling their ranches," says Dale Veseth, who heads the Ranchers Stewardship Alliance of 35 families in Phillips County and whose family has been ranching here since 1886. "They've been a labor of love through the generations." Instead, he wants APF to pay or ranchers to raise... What measures have been taken to protect the wildlife by APF? A) They have borrowed much money and developed new habitat. B) They have hired many farmers to raise bison on their farms. C) They have turned grassland into Disneyland to attract tourists. D) They have bought large land from farmers for bison to live on.
