[EX Q]: Article: One day a student was taking a walk with his teacher. As they went along, they saw a pair of old shoes lying in the path. They were a poor farmer's, who was working in the nearby field. The student turned to the teacher, saying: "we will hide his shoes, and hide ourselves behind those trees, and wait to see what he will do." "My young friend," answered the teacher, "we should never make fun of the poor. Why not put a coin in each shoe, and then we will hide ourselves and watch?" The student did so and they both hid themselves behind the trees. The poor man soon finished his work, and came across the field to the path where he had left his coat and shoes. After putting on his coat, he put his foot into one of his shoes, and felt something hard. Then he bent down to feel what it was, and found the coin. Surprised, he looked at the coin, turned it around and looked at it again. He then looked around, but no person was seen. He put the money into his pocket, and continued to put on the other shoe. His surprise was doubled on finding the other coin. He couldn't control his feelings and fell to his knees, looked up to the sky and expressed his thanks. Then he spoke of his wife, sick and helpless, and his children without bread. He said the help would save them from dying. The student stood there deeply moved, and his eyes filled with tears. "Now," said the teacher, "are you not much happier than if you had hidden the shoes?"

[EX Q]: Article: If you want to see climate change, head north and keep going until you run out of globe. That is easier said than done. The Arctic is home to few people and covered in ice much of the year. But those who make their way to the icy seas of the Arctic Ocean will see a part of the planet that is warming and changing faster than anywhere else. In September, scientists announced at the National Snow and Ice Data Center that Arctic summer sea ice had fallen to its second lowest level since 1979, and probably long before that. The Arctic has lost an area of ice greater than the area of all U.S. states east of the Mississippi River. And what ice remains appears to be getting thinner and weaker. Nick Toberg and Till Wagner are polar ice scientists who are doing sea ice fieldwork. "There is plenty of data to suggest that the ice is becoming thinner as well as smaller in area," they say. The changes happening in the Arctic are a warning for the entire world . As polar expert Walt Meier puts it, " _ Some scientists worry that Arctic sea ice may be going from a downward spiral to a "death spiral", one from which there is no escape. As more ice melts , more dark open water appears. The darkness absorbs more heat, which speeds up the pace of melting. Until recently, many scientists thought it might take until the end of the century for the North Pole to become completely ice free during the summer. Now some believe it could happen by 2030 or even earlier. "The melting is happening faster in the real world than it has in the models," says Nick Toberg.
Question: Nick Toberg may agree that _ .
Options: (A) the ice in the North Pole will stop melting (B) the ice in the North Pole is melting faster than expected (C) the ice in the North Pole will melt before 2030 or even earlier (D) the ice in the North Pole will not disappear until the end of the century

[EX Q]: Article: It was an extremely hot day. My younger brother Walt and I had decided to go swimming in the stream behind Mr Blickez's house, because it would be the only way to cool ourselves down. Across his farm and through some woods was a deep swimming hole supplied by several cold springs . The only problem with our plan was that this farm was guarded by a huge mean Hereford bull . Mr Blickez had told us that Elsie, the animal's name, was the meanest bull in town, maybe even the county, and we believed in him. But the hotter it got, the more we thought there was reason to doubt about what he said. For one thing, we remembered Mr Blickez liked telling tall tales; for another, Elsie seemed like a strange name for a bull. Finally, I talked Mom into asking permission for us to walk through the farm, and Mr Blickez finally agreed. On our way across the farm, we stopped at the fence to admire the swimming hole. The sun shone brightly across the cool waters. We couldn't wait to get there. Suddenly, Walt shouted loudly. Elsie had run to him and was licking his back. I immediately hid under the fence. However, when I looked up, I saw that Elsie wasn't a big mean bull at all. She was just a friendly young cow, and she was going to keep licking my brother's back as long as he stood still. When we discovered the truth, we were so happy. We then ran to the swimming hole and jumped in. The water was just as wonderful as we had dreamed. After that day, we had many good days and we often visited our secret swimming hole guarded by the so-called "big mean bull".
Question: The author and his brother decided to go to swim because _ .
Options: (A) there was no water to take a shower at home (B) the weather was so hot that they couldn't stand it (C) Mr Blickez invited them to his house for swimming (D) they wanted to try their newly-found swimming hole
