Article: Imagination and fantasy can play an important role in achieving the things we fear. Children know this very well. Fred Epstein, in his book I Make It to Five, tells a story he heard from one of his friends about Tom, a four-year-old boy with a cancer in his back bone. He came through several operations and a lot of pain by mastering his imagination. Tom loved to pretend, and he particularly loved to play superheroes. Dr. Epstein explained that it was actually a brilliant way for his young mind to handle the terrifying and painful life he led. The day before his third trip to the operating room, Tom was terribly afraid. "Maybe I could go as Superman," he whispered to his mom. Hearing this, the mother hesitated for a while. She has avoided buying the expensive costume , but finally she agreed. The next day Tom appeared as the powerful Superman, showing off through the hospital halls and coolly waving his hand to the people greeting him along the way. And Tom, with the strength of his fantasy, successfully made it through the operation. The power of imagination need not be reserved for children only. We all have the power to use our fantasies to attempt things we never thought possible, to go through those things that seem impossible, and to achieve what we never believed we could. Just as Dr. Epstein puts it, "If you can dream it, you can do it." It doesn't mean that you should dress as a superhero for your next job interview. But, next time you are tested in a way that seems impossible, imagine what it would take to overcome it. Become the person you need to become to win over your challenge and do it in your mind first. So, let your imagination run wild, and dare to dream.
Answer: He was seriously ill.

Article: In 1883. John Roebling was inspired by an idea to build a spectacular bridge connecting New York with the Long Island. However, bridge building experts throughout the world thought this was an impossible feat and told Roebling to forget the idea, but Roebling could not ignore the vision he had in his mind of this bridge. After much discussion and persuasion he managed to convince his son Washington, an up and coming engineer, that the bridge in fact could be built. The project started well, but when it was only a few months underway a tragic accident on the site took the life of John Roebling. Washington was injured and left with a certain amount of brain damage, which resulted in him not being able to walk or talk or even move. "We told them so." "Crazy men and their crazy dreams.'' "It's foolish to chase wild visions." Evcryone had a negative comment to make and felt that the project should be scrapped since the Roeblings were the only ones who knew how the bridge could be built. In spite of his handicap, Washington was never discouraged. One day he was lying on his bed in hospital, seeing the sky and the tops of the trees outside for just a moment with the sunlight streaming through the windows, and a gentle breeze bowing the flimsy white curtains apart when an idea hit him. He decided to make the best use of the only finger he could move. Thus, he slowly developed a code of communication with his wife. He touched his wife's arm with that finger, indicating to her that he wanted her to call the engineers again. Then he used the same method of tapping her arm to tell the engineers what to do. It seemed foolish but the project was under way again. For 13 years Washington tapped out his instructions with his finger on his wife's arm until the bridge was finally completed.
Answer: They are curious and modest.
answer:
Which of the following is true of Washington and his father?

Article: I appreciate how biking to work allows me to be outside for at least a small part of my day. I'm a senior program director. If I didn't bike to work, I'd spend my weekdays almost entirely indoors--underground tunnel. On the bike, I get trees, air and a great way to get to know city neighborhoods. Of course, I also get bad weather and city traffic. But it's worth the trade-off. The weather's not often bad, and rain and snow have their charms. I've been cycling to work since the late 1990s. I started when the city was doing some construction in the subways and rerouting passengers, which would have lengthened my trip considerably. I tried riding my sister- in- law's bike to work one day and liked it, so I bought my own. Even though I hadn't biked since I was a child, I got back into it right away. I bike during all four seasons. In summer, I wear shorts and a T- shirt and carry a messenger bag over my shoulder for my lunch and anything else I need. Once at the office, I change into business- casual clothes. In winter, I wear layers and a thin hat under my helmet. A cold winter day can be the best time to be on a bicycle. When the air is clear, free of oppressive summer haze, the city can look beautiful. Biking to work also _ during the workday itself. I have a rack on the back of my bike that accommodates panniers that allow me to pick up groceries. During work hours, a colleague will occasionally need to send or retrieve documents by messenger. If I have the time, I volunteer. Pedaling 30 blocks and back is a nice way to take a break from work--and to save the office a few bucks on messenger fees. I'm sure that some people thinking my mode of transportation might be afraid of Midtown traffic. I'm no hero; I don't want to get hurt riding to work. It just takes time getting used to it. There's a risk, but all travel has risks. They're worth it to me.
