The 14-year-old and her family had traveled by plane from Canton, Ohio. Now, as they approached the village, hundreds of cheering schoolchildren lined the entrance to the Hoa Lac School, a two-story concrete building that Carly had raised money for. Carly started helping others at eight, handing out Thanksgiving baskets at church to families in need. It was a snowy day, and she saw many girls didn't have warm coats. The next November, she went door to door asking for used coats, hats, gloves and scarves, and then handed them out with the baskets. But Carly wanted to do more. She remembered her grandmother's Rotarv Club ("") had, years earlier, raised money to build a school in Vietnam. That was what she now wanted to do. At 12, she began to raise money for Vietnamese children with a PowerPoint presentation. "The kids in rural Vietnam don't have decent schools. I want to give them a place to make their lives better," she told a room of 200 Rotarians. That summer, Carly set off with her family across Ohio, visiting three or four Rotarv Clubs a week. "We traveled like crazy people to all these meetings," recalls her mother, Kris. At first they got no donations. But one night, Carly and her dad, Fred, pulled up to a building in Minerva, Ohio. Carrying a laptop, a projector and a screen, they walked into a bar where 15 people were sitting around a long table. There was dead silence after Carly finished her presentation. Fred thought that was never going to work. Then someone made a motion: "Let's give this girl check right now." Minutes later, Carly walked out with her first donation: $500. Not everyone was _ about the idea of helping Vietnam. "Why should we help it?" asked one veteran . Carly replied simply, "They're kids. And I'm just a kid who wants to help out." As word spread, individual donors sent checks for as little as $5. A restaurant chain contributed $1,000. Carly's coach organized...

Read the following article and select the best answer. Article: Do we really know what dinosaurs looked like? Of course we do. We see them everywhere, not only in museums, but also in movies, magazines, and even in the toys we get from McDonald's. Since the days of early cinema, dinosaurs have captured our imaginations. They are often shown as scaly beasts with sharp horns and crocodile-like bellies . But the big screen dinosaurs are "a leap from what we know", Mark Norell, who studies dinosaurs at the American Museum of Natural History in New York, told Discover magazine. The reality of drawing dinosaurs for movie studios, magazines, or museums is that the artist often only has half of a skeleton to work with. Many existing and newly-discovered dinosaurs do not have a complete skeleton, which makes it difficult to tell what they looked like. And even with a complete skeleton, there is a lot of room for interpretation. "Look at an elephant's trunk and ears," Jason Brougham, a dinosaur sculptor at the American Museum of Natural History, told Discover magazine. "It's impossible to guess those features by only looking at the skeleton." Researchers suggest that the dinosaurs of old could have had trunks like an elephant or even red necks like a turkey. They could have had colorful spots, stripes , and other interesting patterns on their bodies, just like snakes. Yet, with only a few fossilized bones to study, it is impossible to know for sure. Remember the cruel and quick-running velociraptors in the US film Jurassic Park? Now experts believe that they were much smaller than in the movies, about the size of a large chicken, the BBC has reported. Since the 1990s, some well-preserved dinosaur fossils have been found in China's Liaoning province. Thanks to that, we have known for a while that one group of dinosaurs was covered in feathers. And thanks to the recent discovery of a feathered plant-eating species in Russia, many scientists now believe more dinosaurs than we previously thought had feathers, much like a chicken. Also, in 2007, scientists confirmed that... Question: The author mainly makes his point by _ . - making contrasts - giving examples - quoting numbers - describing movie scenes
