[Q]: 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.
Answer: It made them able to compete with the wolves
[A]: What was the effect of encouragement on the dogs?

[Q]: Article: My father left me a treasure when he died. It wasn't a big house or a car. It wasn't cash or gold. In the eyes of the world my father died a poor man. He was a simple mechanic who worked hard to support his family. My father's treasure, rather, was in a thousand wonderful memories that he gave me over the course of his life. One particular one stood out in my mind today. I was just a boy playing in the backyard of a friend's house while my father spent the afternoon under the hood of an old car, trying to get it running again. It seemed to take hours and I wasn't sure whether he could bring the ancient car back to life again this time. At long last, though, he closed the hood and turned the key in the ignition . There was a sweet smile of satisfaction on his face as the engine started. There was a twinkle of joy in his eye when he shook his head. And there was a quiet hum of happiness in his voice as we drove back home that day. This memory made a home in my heart and became a priceless pearl for my soul to cherish. Time and time again, my father showed me that a kind life, a giving life and a heavenly life was created one choice at a time. Not all of his choices were the right ones, but most of them were. He did the best he could. He lived the best he could. And he helped to bring out the best in me, too. He once said to me, "It is lucky that all of your choices are driven by love and inspired by joy." As I look back into those memories my father left me, I realize that each one of them inspired me to live and to love. May all of your choices bring memories of happiness to those around you!
Answer: Memories of his father and himself.
[A]: What was the most precious thing the author's father passed on to him?

[Q]: Article: It was the last day of my four-month interview to hold the job as a salesman in the World Trade Center -- in simpler words, an end to being perfect for four months. I took the last drop of my coffee, pushed in my chair, and said goodbye to my family -- little did they know, this could have been my final goodbye. I went to room 911, as I had the past three times, to meet my boss, Mr. Clarke. I was just about to have a seat, when suddenly I heard the sound of explosion. Then, the floor beneath my feet began shaking, which was when I began to realize that something had gone completely wrong. "Run! Let's get out of here!" Mr. Clarke cried. Seconds after the first massive explosion, I heard another explosion from way above. My heartbeat seemed to be the drum of a heavy-metal song and all the employees were rushing to get out; the lifts were out of order, and only screaming could be heard up and down the stairwell. All of us were unaware at the time that this was the airplane hitting the tower. Fire then began to swallow the walls and all you could see is gray smoke. Mr. Clarke had fallen and went unconscious. I used all my strength to throw his heavy weight on my shoulders and run down the steps. I then felt myself sinking into the floor. I ran and ran, but I was not going anywhere. The only option left was to jump. With Mr. Clarke still lying in my arms, I closed my eyes and jumped. My boss safely reached the edge of the trampoline a group of firemen held beneath us. However, I landed on the concrete floor and suffered a broken back and neck, which was considered lucky.
