Read the following article and select the best answer. Article: American author Mark Twain once noted that "life would be surely happier if we could only be born at the age of 80 and gradually approach 18." Twain's words were only one of many complaints about aging. The ancient Greek poet Homer called old age "hateful", and William Shakespeare termed it "terrible winter". Alexander the Great, who conquered most of the known world before he died around 323 B.C., may have been looking for a river that healed the of age. During the 12th century A.D., a king called Prester John ruled a land that had a river of gold and a fountain of youth. But the name linked most closely to the search for a fountain of youth is 16th-century Spanish explorer Juan Ponce de Leon. He thought it would be found in Florida. In St. Augustine, the oldest city in the U.S., there's a tourist attraction. It is said to be the fountain of youth that Ponce de Leon discovered soon after he arrived in what is now Florida in 1513. However, elderly visitors who drink the spring's water don't turn into teenagers. But the tale of the search for a fountain of youth is so appealing that it survives anyway, says Ryan K. Smith, a professor of history. "People are more attracted by the story of looking and not finding than they are by the idea that the fountain might be out there somewhere." Still, a few grains of truth have helped to support . Kathleen Deagan, a professor of archaeology, says a graveyard and the remains of a Spanish mission dating back to St. Augustine's founding in 1565 have been discovered near the so-called fountain of youth. Michelle Reyna, a spokesperson for the Fountain of Youth Archaeological Park in St. Augustine, says the fountain has been a tourist attraction since at least 1901 and may have been attracting visitors since 1860. Question: According to the passage, who searched for a fountain of youth _ ? - Ponce de Leon - William Shakespeare. - Kathleen Deagan - Michelle Reyna
Ponce de Leon

Read the following article and select the best answer. Article: He is a familiar sight, the old man who asks change from drivers stopped at a red light on East 35th Street in Slidtown Manhattan every day. After all, he has been at it for 17 years now, seven days a week. With the help of a walker, he hobbles between lanes of traffic, approaching drivers, offering newspapers --- often a free paper collected from boxes on the sidewalk nearby --and asking for change."Help a guy out?" he repeats to drivers who will usually hand over a dollar or some change. Most drivers simply regard him as another homeless down-and-out ,but every so often one might realize that it's the legendary comedian Professor Irwin Corey, who is now 98. Over his eight-decade career, he has been on television and in comedy clubs, nightclubs and concert halls worldwide. He began his stage career on Broadway in 1943. Indeed, he still performs fairly regularly -- a week ago he flew to Chicago to play two nights at a local club. And though he has a homeless appearance, Mr. Corey lives in a comfortable 1840 carriage house on East 36th Street between Lexington and Third Avenues that he estimates could sell for $3.5 million. Mr. Corey said he gathers his daily take-- usually about $100, though there have been $250 days-- every few months and donates the money to a charity that buys medical supplies for children in Cuba. As for the drivers he solicits, Mr. Corey said, "I don't tell them where the money's going, and I'm sure they don't care." Mr. Corey has traveled to Cuba to donate personally. There are photographs of him with President Fidel Castro on his wall. One is with an inscription by Castro: With admiration, gratitude and affection. Question: Corey raises money in order to _ - help kids in Cuba build their acting career - improve some poor children's health - offer medical supplies to the homeless - provide the elderly with financial support
improve some poor children's health

Read the following article and select the best answer. Article: The researchers, led by Hwang Woo-suk, insist they cloned an Afghan hound, only to help investigate human disease, including the possibility of cloning stem cells for treatment purposes. But others immediately renewed calls for a global ban on human reproductive cloning before the technology moves any farther. "Successful cloning of an increasing number of species confirms the general impression that it would be possible to clone any species of mammals, including humans," said Ian Wilmut, a reproductive biologist at the University of Edinburgh who produced the first cloned mammal, Dolly the sheep, from an adult cell nearly a decade ago. Researchers have since cloned cats, goats, cows, mice, pigs, rabbits, horses, deer, mules and gaur, a large wild ox of Southeast Asia. So far, efforts to clone a monkey or another primate with the same techniques have failed. Uncertainties about the health and life span of cloned animals continue to exsist; Dolly died at a young age in 2003 after developing cancer and arthritis. Wilmut and others _ Hwang's achievement, reported Wednesday in the journal Nature. But they said politicians and scientists must face the larger issue -- how to go on with the research without crossing the moral boundary of copying human life in the lab. "The ability to use the technology is hopeful," said Robert Schenken, president of the American Society for Reproductive Medicine. "However, the paper also points out that in dogs as in most species, cloning for reproductive purposes is unsafe." The cloned puppy was the lone success from more than 100 dogs implanted with more than 1,000 cloned embryos. In a news conference in Seoul, the cloning team also condemned the reproductive cloning of humans as "unsafe and inefficient." Human reproductive cloning already is banned in South Korea. Other nations, including the United States, are divided on whether to ban just human cloning or cloning of all kinds, including the production of stem cells. Question: Accrding to the passage, scientists haven't been able to clone a _ so far. - deer - mule - monkey - mouse
