Article: Many Americans are turning to Japan, they think, a country of high academic achievement and economic success, for possible answers. However, the answers provided by Japanese preschools are not the ones Americans expected to find. In most Japanese preschools, surprisingly little emphasis is put on academic instruction. In one survey, 300 Japanese and 210 American preschool teachers, child development specialists, and parents were asked about various aspects of early childhood education. Only 2 percent of the Japanese respondents listed "to give children a good start academically" as one of their top three reasons for a society to have preschools. In contrast, over half the American respondents chose this as one of their top three choices. To prepare children for successful careers in first grade and beyond, Japanese preschools do not teach reading, writing, and mathematics, but rather skills such as determination, concentration, and the ability to work as a member of a group. The huge majority of young Japanese children are taught to read at home by their parents. Like in America, there is diversity in Japanese early childhood education. Some Japanese kindergartens have specific aims, such as early musical training or potential development. In large cities, some kindergartens are attached to universities that have elementary and secondary schools. Some Japanese parents believe that if their young children attend a university-based program, it will increase the children's chances of eventually being admitted to top-rated schools and universities. Several more progressive programs have introduced free play as a way out for the heavy intellectualizing in some Japanese kindergartens.

Article: Many of the world's pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the needs of the people leads to further pollution by industry. If the rapid increase of world population in countries continues at the present rate, there may be much greater harm to human beings. Some scientists speak of the increase in numbers of people as "population pollution." About 2,000 years ago, the world population was probably about 250 million. It reached a billion in 1850. By 1930 the population was two billion. It is now three and a half billion. It is expected to double by the year 2,000. If the population continues to grow at the same rate, there will be 25 billion in the world a hundred years from now. Man has been using the earth's resources more and more rapidly over the past years. Some of them are almost used up. Now many people believe that man's greatest problem is how to control the growth of the population. The material supplies in the world will be far from enough to support the human population in time to come, if the present rate of increase continues. Already there is overcrowding in many cities and starvation in some countries. Should man's population keep on growing so rapidly as before? Many people believe that human survival in the future depends on the answer to this question.
Question: The rapid increase in population is considered to be _ .
Options: (A) the increase of resources (B) population pollution (C) the development of mankind (D) the present rate
answer:
B

Article: Robert Spring, a 19 century forger ,was so good at his profession that he was able to make his living for 15 years by selling false signatures of Americans. Spring was born in England in 1813 and arrived in Philadelphia in 1858 to open a bookstore. At first he became rich by selling his small but real collection of early U.S. autographs . Discovering his ability at copying handwriting, he began imitating signatures of George. Washington and Ben Franklin and writing them on the title pages of old books. To lessen the chance of detection , he sent his forgeries to England and Canada for sale. Forgers have a hard time selling their products. A forger can't deal with a respectable buyer but people who don't have much knowledge in the field. Forgers have many ways to make their work look real. For example, they buy old books to use the aged paper of the title page, and they can treat paper and ink with chemical. In Spring's time right after the Civil War, Britain was still fond of the Southern states, so Spring invented a respectable maiden lady known as Miss Fanny Jackson, the only daughter of General "Stonewall" Jackson. For several years Miss Fanny's financial problems forced her to sell a great number of letters and manuscripts . Spring had to work very hard to satisfy the demand. All this activity did not prevent Spring from dying in poverty, leaving sharp-eyed experts the difficult task of separating his forgeries from the originals.
Question: Why did Spring sell his false autographs in England and Canada?
Options: (A) There is a greater demand there than in America. (B) There was less chance of being detected there. (C) Britain was Spring's birthplace. (D) The price were higher in England and Canada.
answer:
B
