question:
Article: Two thieves came to a house to steal something. They dug a hole in the wall of the house. There lived many mice in the house. The woman in the house saw a mouse crawl into the house in the moonlight. "Look! In comes one," she said to the man in the house. The thief was so frightened that he hurriedly crawled out of the house and said to the one waiting outside, "She found me when I was just in." But the thief outside didn't believe him, so he said, "Let us try to crawl into the house together." At that time two mice happened to crawl into the house, too. The woman saw the mice and shouted, "In come two, catch them!" The two thieves were terribly frightened. The man in the house said, "You saw them come in but where are they? I will catch them tonight." The two thieves started running away at once. The two thieves wanted to make it clear whether they had been found or not the night before. The next day they acted as men selling sweet potatoes and came before the house. The man and the woman were ploughing in their fields. The rope broke and the woman came home for a rope. She saw two men selling sweet potatoes and wanted to buy some. She picked out two which looked like mice. At the time the man couldn't wait for her any longer in the fields and he ran back from the fields to hurry her up. The woman showed the sweet potatoes to the man and said, "How they look like the two of last night." The man said, "I asked you to fetch a rope, why don't you hurry for it?" The two thieves ran away very quickly without their sweet potatoes.

Article: For new countries joining the European Union, and older ones getting used to their dark red passports, becoming "Europeans" is a bit like marrying into a large, eccentric family. Europeans have a lot in common but it is their differences, not their similarities, that attract the attention of sociologists and market researchers, and are more interesting. * 35% of Germans live alone, but only 9% of Spaniards. Perhaps this explains why Spaniards lead Europe in the habit of going out for a drink. * The British attend more adult evening classes than anyone else in Europe, and the Belgians least. So it can't just be the dark evenings. There are no figures on how many Britons go for a drink afterwards. If there were, they might be up at the top with Spain! * The British think black cats are lucky. Every other European country regards them unlucky. * The Dutch and Germans are the greatest caravaners , but the Germans like bigger beds in their caravans. * The French are the most athletic Europeans. Next come the Dutch. But the Belgians, just over the border, play fewest sports. * The Germans spend twice as much on heating as the Spaniards. Well, of course they do, it's colder. * Dutch husbands do the household shopping a lot more often than Italians or Spaniards. * The French are the champion public transport commuters of Europe. If you hate commuting, go and live in the Netherlands, where journeys to work are shorter than anywhere else. * The amount of direct eye-contact between strangers is three times greater among Spaniards than it is among the British or Swedes. Sharing a lift is torture for both the British and the Swedish. * No European countries really agree with any other about how to make good coffee. All of them are different. There are exceptions to all these rules. Deal with them in the spirit of my 8-year-old daughter. "If you don't understand each other's language, you just laugh a lot, and eat, and point at things."

Article: Since the first Earth Day in 1970, Americans have gotten a lot "greener" toward the environment. "We didn't know at that time that there even was an environment, let alone that there was a problem with it," says Bruce Anderson, president of Earth Day USA. But what began as nothing important in public affairs has grown into a social movement. Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. "The understanding has increased many, many times," says Gaylord Nelson, the former governor from Wisconsin, who thought up the first Earth Day. According to US government reports, emissions from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons. The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of "Green thinking " has become part of practices. Great improvement has been achieved. In 1988 there were only 600 recycling programs, today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution. Twenty-five years ago, there were hardly any education programs for environment. Today, it's hard to find a public school, university, or law school that does not have such a kind of program. "Until we do that, nothing else will change!" says Bruce Anderson.
Question: According to Anderson, before 1970, Americans had little idea about _ .
Options: (A) the social movement (B) environmental problems (C) recycling techniques (D) the importance of Earth Day
answer:
B
