Article: An article published recently in the scientific journal Nature is shedding new light on an important, but so far little has been appreciated, aspect of human evolution. In this article, Professors Dennis Bramble, and Daniel Lieberman suggest that the ability to run was a decisive factor in the development of our species. According to the two scientists, humans possess a number of anatomical features that make them surprisingly good runners. "We are very confident that strong selection for running,which came at the expense of the historical ability to live in trees-was helpful in the origin of the modern human body form," says Bramble, a biology professor at the University of Utah. Traditional thinking up to now has been that the upright body form of modern humans has come about as a result of the ability to walk, and that running is simply a by-product of walking. Furthermore, humans have usually been regarded as poor runners compared to such animals as dogs, horses or antelopes. However, this is only true if we consider fast running over short distances. Even Olympic athlete can hardly run as fast as a horse can gallop, and can only keep up a top speed for fifteen seconds or so. Horses and antelopes, on the other hand, can run at top speed for several minutes, clearly outperforming us in this respect. But when it comes to long-distance running, humans do astonishingly well. They can maintain a steady pace for miles, and their overall speed compares favorably with that of horses or dogs. Bramble and Lieberman examined twenty-six anatomical features found in humans. One of the most interesting of these is the nuchal ligament . When we run, it is this ligament that prevents our head from pitching back and forth or from side to side. Therefore, we are able to run with steady heads held high. The nuchal ligament is not found in any other surviving primates , although the fossil record shows that Homo erectus, an early human species that walked upright, much as we do, also had one. Then there are our Achilles... Question: It appears that the nuchal ligament _ . Yes or no, is the answer "enables us to run with steady heads"?
No

Article: Edward Wilson The Future of Life, . Edward Wilson is America's, if not the world's, leading naturalist. In The Future of Life, he takes us on a tour of the world's natural resources . How are they used? What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity of our earth. Wilson begins with an open letter to the pioneer in environment protection, Henry David Thoreau. He compares today's Walden Pond with that of Thoreau's day. Wilson will use such comparisons for the rest of the book. The problem is clear: man has done great damage to his home over the years. Van the earth, with human help, be made to return to biodiversity levels that will be able to support us in the future? Biodiversity, Wilson argues, is the key to settling many problems the earth faces today. Even our agricultural crops can gain advantages from it. A mere hundred species are the basis of our food supply, of which but twenty carry the load. Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas. At the end of the book, Wilson discusses the importance of human values in considering the environment. If you are to continue to live on the earth, you may well read and act on the ideas in this book. Question: We can infer that the text is _ Yes or no, is the answer "a book review"?

No

Ques: Article: Becoming a teacher is one of the best ways to make a difference in the life of a child and even older students. Here are some great scholarships and grant opportunities to get the ball rolling on your dreams of becoming a teacher. Straightforward Teacher Program This is one of the most popular and unique scholarships available for students working towards becoming teachers. The foundation offers their scholarships every three months as opposed to each year. During each payment, four students receive a $500 scholarship. Prezell Robinson Scholarship Program While this scholarship is available only to students in the state of North Carolina, it is so incredibly helpful that many students choose to study in the state for the only purpose of receiving it. It is offered to college students who come from low-income high schools or families that are interested in pursuing a long term career in education at any level. New York State Scholarship Program Officials in the state of New York founded this program to award students who want to give back to their community through their ability to teach. The catch for this scholarship is that the students must be pursuing a teaching career in mathematics or science at the secondary level. Also, because the program was designed to improve the education system in New York, the candidates must sign a service contract agreeing to work full time within the state for at least five years after graduation. Coca-Cola Scholarships You may have many opportunities for grants and scholarships through The Coca Cola Foundation. There is the Coca Cola Teaching Foundation that will provide free money for students pursuing an education in the teaching field. This is the most obvious for teachers, but do not be afraid to check out their other offers. Funds For Teachers Not all scholarships or grants are for students entering or already in college. The Funds for Teachers scholarships are for graduates who are already working in the field, but want to improve their possibilities, skills and... Question: How many students get their scholarships each year according to the Straightforward Teacher Program ? Yes or no, is the answer "Sixteen"?
Ans: No

Ques:Article: Scientists fear rising energy bills may lead to an increase in obesity after discovering a link between poorly-heated homes and higher body -fat. Researchers from the University of Stirling's Behavioural Science Centre set out to explore claims that warm indoor temperatures have contributed to rising obesity levels in winter.Instead, the team found that people who live in well-heated homes are more likely to have low body mass index levels while those who keep their heating turned down or off tend to be heavier. Dr Michael Daly, behavioral scientist and senior lecturer, said: "We set out to investigate the scientific claims that cooler indoor temperatures help us maintain a healthy weight by pushing our bodies to use up more energy. In fact, the research suggests people may eat less and burn more energy when in a warmer indoor environment. The 13-year study, published in the journal Obesity, involved more than 100,000 adults across England. Researchers found reduced weight levels among people living in homes heated to above 23degC(73F), which involved about 15,000 of the households studied. Dr Daly said: "As national gas bills continue to rise faster than the rate of inflation, this research suggests the obesity could worsen where heating is turned down below comfortable levels or off for long periods to cut costs." This is not just about people who live in well-heated homes being in the financial position to afford more expensive low-calorie foods, exercise classes and sporting activities, and therefore finding it easier to maintain a low BMI level.The study took age, sex, social class and other factors into account. "The comfortable temperature of 20degC -23degC is where we feel comfortable in our clothes and are neither hot nor cold.At temperatures above this, we use more energy and we eat less because our appetite is affected." Question: The findings of the research can be described as _ . Yes or no, is the answer "surprising"?

Ans:
No
