[EX Q]: Article: San Francisco has its cable cars. Seattle has its Space Needle. And, Longview has its squirrel bridge. The bridge, which has attracted international attention, is now a local landmark. The Nutty Narrows Bridge was built in 1963 by a local builder, Amos Peters, to give squirrels a way to cross the busy road without getting flattened by passing cars. The original bridge was built over Olympia Way on the west edge of the library grounds. Before the bridge was built, squirrels had to avoid traffic to and from the Park Plaza office building where office staff put out a nutty feast for the squirrels. Many times, Peters and others who worked in and near Park Plaza witnessed squirrels being run over. One day Peters found a dead squirrel with a nut still in its mouth, and that day's coffee break discussion turned into squirrel safety. The group of businessmen cooked up the squirrel bridge idea and formed a committee to ask the blessing of the City Council .The Council approved, and Councilwoman Bess LaRiviere named the bridge "Nutty Narrows." After architects designed the bridge, Amos Peters and Bill Hutch started Construction, They built the 60-foot bridge from aluminum and lengths of fire hose . It cost 1,000. It didn't take long before reports of squirrels using the bridge started. Squirrels were even seen guiding their young and teaching them the ropes. The story was picked up by the media, and Nutty Narrows became know in newspapers all over the world. In 1983, after 20 years of use, Peters took down the worn-out bridge. Repairs were made and crosspieces were replaced. The faded sign was repainted and in July 1983, hundreds of animal lovers attended the completion ceremony of the new bridge. Peters died in 1984, and a ten-foot wooden squirrel sculpture was placed near the bridge in memory of its builder and his devotion to the project.

[EX Q]: Article: Nathan's second-hand bike was good enough to get him anywhere he wanted to go. Of course, it couldn't match Tim's in a normal speed race, but all the fancy gears in the world wouldn't get you up Black Mountain. It was so steep in places that you had to get off your bike and push. On this particular afternoon, the odds were all on Nathan's side. First, he was stronger. Tim had always been thin, but recently he'd started to grow so fast that his arms and legs were like pieces of spaghetti. As well as being considerably fitter than his friend, Nathan knew the shortcuts up prefix = st1 /BlackMountain. So when Nathan accepted the challenge, he was sure he'd win. He nearly always did, in competitions with Tim. That was what was strange. Tim was so competitive, and yet he wasn't any good at physical things. By the time the two boys were three quarters of the way to the top, Nathan was clearly ahead. While the road zigzagged back and forth up the mountainside, in certain places, there were also vertical tracks, where water rushing down the slope in winter had bitten erosion courses into the soil. These had in turn been so overgrown by bushes and long grass in the spring that they looked like tunnels through the bush. The trick was to know where you could cut off a whole bend in the road by leaving the road and pushing your bike up one of these half-hidden pathways. If you chose the wrong one you'd struggle up for ten minutes and then suddenly reach a dead end. Then there was no choice but to go back.
Question: What did Tim challenge Nathan to do?
Options: (A) test who had the fastest bike (B) decide who was the most competitive (C) find the secret tracks on the mountain (D) race to the top of BlackMountain

[EX Q]: Article: There are many famous writers in the English world, among whom Jane Austen (1775--1817) has been popular with all ages. But then Jane Austen wrote her novels in England, she was writing about a world that most of us would not recognize. But today Austen's books are in greater demand than ever. In the last ten years, five of the six novels have been made into Hollywood films, while her books continue to be bestsellers. So why is Austen still popular? Richard Jenkyns, a professor of English at Oxford University, argues that her novels still appeal to people because they focus on issues that are as _ today as they were when she wrote them. Her novels are about women trying to find a perfect husband, but also explore issues surrounding marriage, friendship and the family. "The plots are fairly timeless stories about human interaction which are familiar to us," Jenkyns says. The most famous book Austen wrote is Pride and Prejudice,a love story betweenElizabeth Bennett and Mr. Darcy. At first the two characters do not get on. They finally fall in love, but still have to overcome opposition to their relationship from their families. All of Austen's books are easy to read, making them popular with children and adults, but they work on different levels so people can take what they need from them, author Kate Henry says. Austen is often praised as the greatest romance writer in the English language, so it is surprising she remained unmarried. "Maybe she was too much of a romantic, waiting for a perfect man," Henry says.
Question: Which of the following can NOT explain why Austen is still popular?
Options: (A) Her novels are all about love and marriage. (B) Her novels still make sense to today's people. (C) All her novels are easy to read. (D) Her novels benefit people of different reading levels.
