Article: The African elephant, the largest land animal remaining on the earth, is of great importance to African ecosystem . Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna surroundings in which it lives, therefore _ of existence for millions of other animals that live in its habitat. It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas . In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters. Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well. What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem. Question: What is the passage mainly about? Yes or no, is the answer "The effect of African elephants' search for food."?
No

Article: Education is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them. Our purpose is to fit them for life. In some modern countries it has for some time been fashionable to think that by free education for all -- one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degree; they refuse to do what they think "low" work; and, in fact, work with hands is thought to be dirty and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor; we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our towns... In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability and, secondly, that we can realize that all jobs are necessary to society, and that is very bad to be ashamed of one's work. Only such a type of education can be considered valuable to society. Question: The writer wants to prove that _ . Yes or no, is the answer "our society needs all kinds of jobs"?
(Answer)
No

Ques: Article: A 26-year-old Montreal man appears to have succeeded in his quest to barter a single, red paper clip all the way up to a house. It took almost a year and 14 trades, but Kyle MacDonald has been offered a two-storey farmhouse in Kipling, Sask., for a paid role in a movie. MacDonald began his quest last summer when he decided he wanted to live in a house. He didn't have a job, so instead of posting a resume, he looked at a red paper clip on his desk and decided to trade it on an Internet website. The response was immediate --a fish pen was offered for exchange. MacDonald then bartered the fish pen for a handmade doorknob from a potter in Seattle. In Massachusetts, MacDonald traded the doorknob for a camp stove. He traded the stove to a U.S. soldier in California for a generator. Then he exchanged the generator for an "instant party kit" -- an empty keg and an illuminated Budweiser beer sign. MacDonald then traded the keg and sign for a snowmobile. He bartered all the way up to an afternoon with rock star Alice Cooper, a KISS snow globe and finally a paid role in a Corbin Bernsen movie. "Now, I'm sure the first question on your mind is, 'Why would Corbin Bernsen trade a role in a film for a snow globe? A KISS snow globe,' MacDonald said on his website."Well, Corbin happens to be arguably one of the biggest snow globe collectors on the planet. Now, the town of Kipling, Sask., Canada, with a population of 1,100,has offered MacDonald a farmhouse in exchange for the role in the movie. The town is going to hold a competition for the movie role. MacDonald said: "There're people all over the world that are saying that they have paper clips clipped to the top of their computer, or on their desk or on their shirt, and it proves that anything is possible and I think to a certain degree it's true." MacDonald, who has attracted international media attention in his quest, said the journey has turned out to be more exciting than the goal. "This is not the end. This may be the end of this part of the story, but this story will go on." Question: What can we learn about MacDonald? Yes or no, is the answer "His success largely depended on the Internet."?
Ans: No

Ques: Article: Millions of people all over the world spend their holidays travelling. They travel to visit other countries, modern cities and ancient towns.
