Article: When nature is left alone, a balance is reached among the animals and plants living in one area. But when man starts his work in nature, the balance is likely to be destroyed. He grows a crop and takes it away to eat; then there are no dead leaves to fall on the ground, holding water while it sinks into the surface, or decaying and adding humus to the soil. Unless a farmer acts with knowledge and skill, he is therefore most likely to make the land poorer. To take the place of the useful matter in the crops that he removes, he uses some kind of fertilizer. Chemical fertilizers are of great help, but the waste products of animals and decaying remains of plants should also be put on the land. In some places, it is a habit to burn waste material lying about, but such burning destroys the useful matter in the dead plants. Although the ashes that are left are valuable when put on the land, a better practice is to bury the waste so that it decays and increases the humus in the soil. In the past, when the world population was much lower than it is now, a man had little difficulty in ordinary times in growing the food that was needed. When a field had been used some years and had become tired, the farmer could move to another place. The tired land then slowly recovered. Gradually grasses and other plants would appear on it and its productive power would slowly return to normal through their decay. But nature, left alone, would take a long time to bring back the land to its former state; the length of time required would depend on local conditions, but it might well be ten years. It is a bad practice to grow the same crop in a field year after year. If the crop is changed, the land will suffer less because it is treated and used in a different way. Different plants have different effects on the soil. Therefore, a change of crop will do less harm than the growing of the same crop year after year and a regular change to grass will do good to the soil. Much will therefore be gained if different crops are grown one... Question: We can learn from the passage that the tired land has gradually recovered _ . Yes or no, is the answer "after new grasses and other plants have decayed again"?
No

Article: Getting a good education is more important today than ever before. It is the best thing you can do to build a better future for your children and yourself. Most children in Canada attend public schools. Public schools are completely founded by governments through tax income. Boys and girls attend the same school and share the same courses and classes. Schooling in Canada is provided in English and in French. The rest of Canadian children attend private schools,which are supported mainly by fees paid directly by parents. Some private schools enroll only boys or girls. By law,children must attend school from age 5 to 16.Children are usually in school between 8:30 or 9:00 a.m.,and 3:00 or 4:00 p.m.Monday through Friday,from September to the middle of June. There are several different levels in the Canadian education system. The first is called Elementary Schools. In most provinces Elementary Schools include Kindergarten through Grade 7 or 8. From Grade 8 or 9 through 12 or 13,children go to Secondary School or High School. High School students must take certain courses for several years,such as English or French and mathematics. Some courses help students get a job after they graduate from school. Other courses prepare students for college or university. In Canada,teenagers usually make these choices for themselves,with the advice of their teachers,guidance counselor and parents. Schools usually offer extra activities at the end of the normal school day. These include sports,games,music and clubs. Most elementary and high schools encourage parents to take part in school activities. Parents' nights are organized from time to time. These are chances for parents to discuss their children's progress with teachers. You may wish to bring a friend with you. After graduating from high school,many young adults continue their studies through postsecondary education. Question: Which of the following statements is TRUE according to the passage? Yes or no, is the answer "If you don't send your fiveyearold child to school in Canada--you break the law in Canada."?
(Answer)
No

Ques: Article: The secret of carrier pigeons' unbelievable ability to find their way home has been discovered by scientists: _ follow the roads just like we do. Scientists now believe the phrase "as the crow flies" no longer means the shortest most direct route between two points. They say it is likely that crows and other day birds also choose AA-suggested routes, even though it makes their journeys longer. Scientists at Oxford University spent 10 years studying homing pigeons using global positioning satellite (GPS) and got a surprising result. The birds often don't use the sun to decide their directions. Instead they fly along motorways, turn at crossing and even go around roundabouts , adding miles to their journeys. "It really has knocked our research team sideways to find that after a decade-long international study, pigeons appear to ignore their inbuilt directional instincts and follow the road system," said Prof Tim Guilford, reader in animal behavior at Oxford University's Department of Zoology. Guilford said pigeons use their own navigational system when doing long distance trips or when a bird does a journey for the first time. "But once homing pigeons have flown a journey more than once, they can fly home on a habitual route, much as we do when we are driving or walking home from work," said Guilford. "In short, it looks like it is mentally easier for a bird to fly down a road. They are just making their journey as simple as possible." Question: Why do homing pigeons tend to follow the road system daring the r journey? Yes or no, is the answer "Because it is easier to make journey simple by following road system."?
Ans: Yes

Question: Article: Jeans are trousers made of a kind of clothe called denim. For many people, blue jeans represent American culture. The history of blue jeans usually begins with a man named Levi Strauss. Although he did not invent the jeans, he is considered the first person to produce and sell this kind of clothing in large amounts. Levi Strauss was born in Bavaria, Germany. In 1847, he and his family moved to the US. He opened a store, first in New York, and then in San Francisco, California. Among the products he sold were jeans. These trousers were especially useful for miners in California who needed clothing made of a strong material. Levi Strauss partnered with a clothing maker named Jacob Davis, who had invented a process for making rivets for jeans. These metal things helped strengthen the blue jean cloth to make the trousers stronger. In 1873, Strauss and Davis received a patent to officially own this invention. They began producing " copper-riveted waist overalls ". In 1928 the Levi Strauss company used the word "Levi's" as the trademark for their products. The 19th-century workers would probably be surprised to know that their trousers would one day become a fashion object. Today, jeans are worn by people of all ages, incomes and lifestyles. Jeans come in many colors other than blue and in many styles and at many prices. A national museum in Washington, D.C. has one of the oldest known pairs of Levi's jeans in its collection. Jeans have come to express different ideas about American culture based on the people who wear them. These include the heroes of the Wild West and famous Hollywood actors like James Dean and Marlon Brando in the 1950s. Writer James Sullivan published a book called Jean: A Cultural History of an American Icon. In the book, he says jeans serve as a sign for two American values, creativity and rebellion . Question: Which of the following statements is TRUE about jeans? Yes or no, is the answer "Strauss and Davis owned the invention of using rivets on jeans."?

No
