Question: 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."

Question: Article: It's a fact that we all dream. Some dreams seem to last for hours, others only for seconds. Some of us have strange dreams, some have interesting dreams, and some of us have unpleasant dreams. Tests in the 1980s showed that these dreams occur within 90-minute cycles, each cycle made up of six stages. In the last stage people experience rapid eye movement, known as REM, and it is in this stage that dreaming takes place. Eighty percent of people who were woken during this sixth stage could easily remember their dreams. On the other hand, when during the first five stages (NREM), only seven percent could describe a dream. However, of these same people woken during the first five stages, 74% were able to remember thinking activity, although they would not call it a dream. NerysDee, who has written about dreams in a book called "Your Dreams and What They Mean" says: "Perhaps during NREM sleep we are sorting out our outer mundane problems, but in REM sleep we are dealing with inside matters." She also makes the following statement about 90-minute cycle: It may also prove the reason why _ who wake in the middle of the night find it impossible to get to sleep again for at least an hour and a half. In other words, until they have missed out one complete 90-minute sleep period.
Question: Which of the following statements about dreams is TRUE?
Options: (A) Everyone dreams but very few can recall what they dream. (B) Some people have long dreams and others have very short ones. (C) People can only remember unpleasant dreams. (D) More than eighty percent of people can remember their dreams.

Question: Article: 1826, a Frenchman named Niepce needed pictures for his business .But he was not a good artist.So he invented a very simple camera .He put it in a window of his house and took a picture of his garden .That was the first photo. The next important date in the history of photography was 1837. That year, Daguerre, another Frenchman, took a picture of his studio. He used a new kind of camera and a different processs. In his pictures, you could see everything very clearly, even the smallest details. This kind of photograph was called a daguerreotype. Soon, other people began to use Daguerre's process. Travellers brought back daguerreotypes from all around the world. People photographed famous buildings, cities and mountains. In about 1840, the process was improved. Now photographers could take pictures of people and moving things. The process was not simple. The photographers had to carry lots of film and processing equipment. But this did not stop the photographers, especially in the United States, where from the 1840s daguerreotype artists were popular in most cities. Mathew Brady was a well-known American photographer. He took many pictures of famous people. The pictures were unusual because they were very life-like and full of personality. Brady was also the first person to take pictures of war. His 1862 Civil War pictures showed dead soldiers and ruined cities. They made the war seem more real and more terrible In the 1880s, new inventions began to change photography. Photographers could buy film readymade in rolls. So they did not have to make the film immediately. They could bring it back to their studios and develop it later, meaning that they did not have to carry lots of equipment. And finally, the invention of the small handheld camera made photography less expensive. With the small camera, anyone could be a photographer. People began to use cameras just for fun. They took pictures of their families, friends and favourite places. They called these pictures "snapshots". Photographs became very popular in newspapers in the 1890s. Soon magazines and books also used documentary photographs. These pictures showed true events and people. They were much more real than drawings. Photography had turned into a form of art by the beginning of the 20th century. Some photographs were not just copies of the real world. They showed ideas and feelings, like other art forms.
