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. Question: Which of the following best describes dolphins? Yes or no, is the answer "Friendly and smart."?
No

Article: 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 limitation is common and 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. Question: Which of the following shows the right way in which lack of sleep causes weight gain? Yes or no, is the answer "more ghrelin and less leptin-feeling hungry-eating more"?
(Answer)
No

Ques: Article: It's hard to track the blue whale, which has almost been killed off by commercial whaling. Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when, with the help of the US Navy, they are able to track a particular blue whale for 43 days recording its sounds. This was possible because of the Navy's former top secret system of underwater listening devices across the oceans. Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies. Earth scientists announced at a news conference recently that they had used the system for closely observing a deep-sea volcanic eruption for the first time and that they planned similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in the ocean and global temperatures. Different layers of ocean water can act as channels for sounds focusing them in the same way a stethoscope does when it carries faint noises from a patient's chest to a doctor's ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles. Question: What is the passage chiefly about? Yes or no, is the answer "The civilian use of a military detection system."?
Ans: Yes

Ques: Article: Edda, a Little Valkyrie's First Day of School Written and illustrated by Adam Auerbach. 32 pp. Christy Ottaviano/Holt. $15.50. Edda's home is in Asgard, "a land full of magic and adventure." But Edda, the littlest Valkyrie, doesn't have quite enough to do, until her father flies her "all the way to Earth for the first day of school." The contrast between home and school is hard to get used to (in one, she can ride reindeer; in the other she gazes guinea pig through glass at the classroom). In his first picture book, Auerbach mixes the two worlds perfectly. Children are likely to appreciate the joke. Planet Kindergarten By Sue Ganz-Schmitt. Illustrated by Shane Prigmore. 32 pp. Chronicle. $14.99. After careful preparations and a successful blastoff, a boy finds himself in a very unfamiliar environment. "We're aliens from many galaxies on Planet Kindergarten," he reflects as he sees his very varied classmates for the first time. Prigmore, who designs for the movie industry, uses black backgrounds and bright colors to give this space adventure visual excitement and humor. The Smallest Girl in the Smallest Grade By Justin Roberts. Illustrated by Christian Robinson. 42 pp. Putnam. $18.99. It makes sense that the author of the long, rhyming lines in "The Smallest Girl in the Smallest Grade" is a children's music performer. The story is about the power of one small person to fight prejudice. Sally, whom no one ever seems to notice, is "paying super extra special attention" to the "terrible stuff" happening around her. When she decides to take action, she's not alone for long. And Two Boys Booed By Judith Viorst. 32 pp. Margaret Ferguson/Farrar, Straus & Giroux. $16.59. Ever felt quietly confident one minute, and a shaking mess the next? In Viorst's story about determination, a little boy wakes up thinking about singing his song in the class talent show. Question: The book The Smallest Girl in the Smallest Grade was published by _ . Yes or no, is the answer "Putnam"?
Ans:
No
