Q: 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.

Q: Article: THURSDAY, July 9 (Health Day News) -- A new study that found that a lower calorie diet slowed the aging process in monkeys could be the best proof yet that restricted diets might do the same for humans. "The big question in aging research is, 'Will caloric restriction in species closely related to humans slow aging?'" said Richard Weindruch, senior author of a paper appearing in the July 10 issue of Science. This is the first clear demonstration that, in a primate species, we' re inducing a slowdown of the aging process -- showing increased survival, resistance to disease, less brain atrophy and less muscle loss. "This predicts humans would respond similarly," added Weindruch, professor of medicine at the University of Wisconsin and an investigator at the Veterans Hospital in Madison. Another expert noted that, despite some highly publicized studies in certain species, the link between restricted eating and longer lifespan has been far from proven. "The idea that dietary restriction extends lifespan in all species is not true. Many strains of rats and mice do not respond. In some strains, it' s actually deleterious," explained Felipe Sierra, director of the biology of aging program at the US National Institute on Aging (NIA), which supported the new study. "The fact that it doesn't work in some mice but it does seem to work in monkeys is surprising and it gives us hope." But there's a larger question: how to change humans' increasingly careless eating habits. "This finding doesn't give me hope that humans are going to go into dietary restriction," added Marianne Grant, a registered dietitian at Texas A&M Health Science Center Coastal Bend Health Education Center in Corpus Christi.
Answer: This experiment indicates restricted diets could extend humans' lifespan.

A: Which of the following statements about Weindruch is true?

Q: Article: Observe a child; any one will do. You will see that not a day passes in which he does not find something or other to make him happy, though he may be in tears the next moment. Then look at a man; any one of us will do. You will notice that weeks and months can pass. Days are greeted with nothing more than resignation . A man can not smile like a child, for a child smiles with his eyes, whereas a man smiles with his lips alone. It is not a smile; but a grin ; something to do with humor, but little to do with happiness. Sir Henry Stewart was a lawyer. He was certainly successful. It is twenty years ago since he came down to our village from London. I remembered some ten years ago when he was made a King's Counsel , Amos and I, seeing him get off the London train, went to congratulate him. We grinned with pleasure; he merely looked as miserable as though he'd received a penal sentence. It was the same when he was knighted. He never smiled a bit. He took his success as a child does his medicine. I asked him one day what it was like to achieve all one's ambitions. He looked down at his roses and went on watering them. Then he said "The only value in achieving one's ambition is that you then realize that they are not worth achieving." I recall this incident, for yesterday, I was passing his house, and had drawn up my cart just outside his garden wall. I had pulled in from the road for no other reason than to let a bus pass me. As I sat there filling my pipe, I suddenly heard a shout of joy come from the other side of the wall. I peered over. There stood Sir Henry doing nothing less than a tribal war dance of unashamed ecstasy . When he saw me staring over the wall, he shouted, "Come and see. Look! I have done it at last! I have done it at last!" There he was, holding a small box of earth in his hand. I observed three tiny shoots out of it. "And there were only three!" he said, his eyes laughing to heaven. "Three what?" I asked. "Peach stones", he replied. "I've always wanted to make peach stones grow, even since I was a child, when I used to take them home after a party, or as a man after a banquet. And I used to plant them, and then forgot where I planted them. But now at last I have done it, and, what's more, I had only three stones, and there you are, one, two, three shoots," he counted. And Sir Henry ran off, calling for his wife to come and see his achievement.
Answer: To watch Sir Henry water roses.
