Ques: Read the following article and select the best answer. Article: This story breaks my heart every time. Just two years after the discovery of tanzanite in 1967, a Maasai tribesman knocked on the door of a gem cutter's office in Nairobi. The Maasai had brought along an enormous block of tanzanite and he was looking to sell. His asking price? Fifty dollars. But the gem cutter assumed that a stone so large could only be glass and refused. It turned out that the gem was genuine and could have been worth close to $3,000,000! The gem cutter missed his chance to hit the jeweler's jackpot and make history. Would you have made the same mistake then? Will you make it today?

Ques: Read the following article and select the best answer. Article: A breathtaking trick potentially left over from our ancestors might be found in us -- the ability to sense oxygen through our skin. Amphibians, animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo. Now the same oxygen sensors found in frog skins and in the lungs of mammals have unexpectedly been discovered in the skin of mice. "No one had ever looked," explained Randall Johnson, a biologist researcher. Mice and frogs are quite distant relatives, so the fact they have these molecules in common in their skin suggests they might well be found in the skin of other mammals, such as humans. "We have no reason to think that they are not in the skin of people too," Johnson said. These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen--a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1a genetically removed from their skin failed to produce this hormone even after hours of such low oxygen. These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia without injecting drugs, which make up a multibillion-dollar market, Johnson said. Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. "It's hard to say what exactly might be done, however--there's a lot we don't know yet," Johnson explained. The scientists... Question: What is Johnson's attitude to the application of the findings to the athletes' training? - Hesitating - Doubting - Positive - Negative
Ans: Positive

Ques: Read the following article and select the best answer. Article: As a boy, Mark Twain caused much trouble for his parents. He used to play practical jokes on all his friends and neighbors. The nature of his jokes often led to violence . He hated to go to school and he constantly ran away from home. He always went in the direction of the nearby Mississippi. He liked to sit on the bank of the river for hours at a time and just gaze at the mysterious island and the passing boats. He learned many things about the river during those days. He learned all about its history and unusual people. He later made them part of the history of America in the book Tom Sawyer and Huckleberry Finn. Mark Twain received his genius from his mother. Obviously he didn't get it from his father. He once stated that he had never seen a smile on his father's face. On the other hand, his mother had the ability to say humorous things. The same ability made Mark Twain an extremely humorous public speaker. Question: According to the passage, Mark Twain was a _ boy. - shy - brave - naughty - poor

Ques: Read the following article and select the best answer. Article: The days of Europeans relaxing in the cafe with a newspaper and a seemingly endless cup of coffee appear to be numbered.A new English expression is popular in Europe these days:"coffee to go." "Five or ten years ago it was much more normal to sit in a cafe for several hours than it is nowadays,"says Joann,who works in a central Berlin coffee bar owned by the Canadian coffee and bakery chain Tim's. "There is a trend towards a more fast-paced life.But people still act surprised when you ask if the coffee is'to go'.You mean I can take it with me? they ask.." "Europe is often five or eight years behind trends in America,"says Joann."In the States.'coffee to go'is part of everyday life." Owing in part to Starbucks,it appears to be very much part of everyday life in many other countries too. The Seattle-based group compete with a growing number of global chains in attempting to reshape coffee drinking cultures in regions including Asia and the Middle East. The US is the model for continental Europe's new"coffee to go"culture:Each of the new cafe bars offers bagels,muffins,brownies and cookies to go with the coffee. But then,"coffee to go''might sound a little odd to English ears used to the words "takeaway"or take one. It does sum up the brisker pace of life since the city resumed its status as the German capital following the fall of the Berlin wall in 1989. As one more sign of the changing times,one of Berlin's most venerable coffee houses,cafe Einstein,has followed the trend by opening a small chain of coffee shops across the city. Taking coffee,slowly and in decorous surroundings,has been a feature of European coffee houses,particularly in German speaking countries,for decades. For the elderly citzens of Vienna it amounts to a ritual when they gather in coffee houses around the city for a cup of their favovrite drink and a piece of rich,creamy cake. Question: From the passage,we can see that_. - "coffee to go" springs in Europe these days - Europe is often a few years before trends in America - America often follows Europe's "coffee to go"culture - it's easy to reshape coffee drinking cultures in the Middle East
Ans:
"coffee to go" springs in Europe these days
