Article: It was a sunny winter day. I had gone down the tower when a blind man came toward me. He kept close to the wall, touching it lightly with his arm. I stood still and looked at him walking toward the tower. "What does a blind man want to climb up the tower for?" I wondered, "Not the view certainly, perhaps he wants to jump. "Thinking of this terrible reason, I thought I should follow him. He went up slowly and stopped from time to time. I followed him a few steps behind. When he got to the first corner of the bell tower, I came close to him. "Excuse me," I said as politely as I could, "but I wonder why you came up." "You'd never guess." he said. "Not the view or the fresh air on this winter day?" "No." he said. "Tell me, then." He smiled, "Perhaps climbing up the tower. You have noticed - and yet, not being blind, perhaps you won't - how the sun shines into the tower through the windows here and there, so that one can feel the cool steps suddenly become quite warm, even in winter. But behind the wall there is shade . There is no place so good as this for feeling the difference between light and darkness. Though I'm blind, I also want to feel the happiness brought by the sunlight. In fact, it isn't my first time to be here." He said and seemed as pleased as a child. I had never thought that even a blind man could have his way to enjoy the beautiful life. But we often paid no attention to its value because we never lost it. We went down the tower together and I left him. From then on, I began to treasure what life has given me.

Article: Humans may be a bad influence on their best friends---at least when it comes to problem-solving. In a task that wasn't very tough, wolves performed must better than dogs. All the animals had to do was pull the lid off a food container, containing a sausage treat. Monique Udell studies animal behavior at Oregon State University in Corvallis. She tested 10 pet dogs and another 10 dogs from an animal shelter. In one set of tests, a person was nearby but did not encourage or discourage the dogs. Those dogs typically spent 10 to 15 percent of their time gazing at the person. They spent a mere 5 percent of their time or less touching the container. Udell offered the same challenge to wolves. These animals had been raised and fed by people but still lived outdoors. Here, the wolves didn't look at the nearby person. Instead, they devoted about 90 percent of the time to struggling with the box holding a treat. When someone walked around the dogs and actively encouraged them to keep trying to open the box, the dogs did spend more time handling the problem. A few more even managed to open the box. But their success rate still did not match the wolves. The dogs and wolves were also tested when no one was present. But even then, the dogs didn't paw or teat the box much more than they did when a human was present.
Question: What was the effect of encouragement on the dogs?
Options: (A) It made their success rate improve a lot (B) It made them seek less guidance (C) It made them a little more devoted to the task (D) It made them able to compete with the wolves
Asnwer: C

Article: "Benjamin Franklin," Walter Isaacson tells us at the beginning of his long (but never boring) new biography, "is the founding father who winks at us." By that, Isaacson explains, he means Franklin is the most human--and most modern--of the men who shaped the American republic. We admire Washington, Jefferson and Adams, but they remain creatures of the 18th century. The man we encounter in "Benjamin Franklin"--funny, pragmatic and selfaware -- seems like one of us, or at least someone we'd like to be. Unlike Washington's cherry tree, Franklin's kite was real. His experiments with electricity made him one of the great scientists of his day. He was a middleclass businessman whose success as a printer and a journalist allowed him to retire at 42--and he devoted the rest of his life to his country. He was diplomat who persuaded the French to back the American Revolution and the author of the first great American autobiography. He was an excellent swimmer. There was almost nothing he couldn't do well, except write poetry. But what truly distinguished Franklin was his talent of being great and human at the same time. He owned slaves as a younger man, but in his last years became an abolitionist .When he fathered an illegitimate son, he acknowledged his fatherhood and took the responsibility of raising the boy. He seems strange today in the joy he took in compiling and creating all those self- improvement _ he published in Poor Richard's Almanac -- "early to bed, early to rise" and so on. Generations of lazy boys could have been happier without that. But he was no hypocrite . Isaacson tells us Franklin practiced what he preached, and often laughed at _ while he did so. By a happy accident, this is the second excellent biography of Franklin to appear in two years, after Edmund S.Morgan's inspiring "Benjamin Franklin."
