Article: Discover Nature Schools programs Becoming Bears (Kindergarten-2 grade) By becoming baby bears, children learn from their "parent" to survive the seasons. Kids will find safety in the spring and learn kinds of food bears eat during the summer, and then create a cave for winter hibernation . After learning the skills needed to survive, students will go out of the cave as an independent black bear able to care for themselves. (1.5-2 hours) Whose Clues? (3-5 grade) Kids will discover how plants and animals use their special structures to survive. Through outdoor study of plants and animals, kids will recognize their special structures and learn how they enable species to eat, avoid their enemies and survive. Using what they have learned, kids will choose one species and tell how they survive in their living places. (3-4 hours) Winged Wonders (3-5 grade) Birds add color and sound to our world and play an important ecological role. Students will learn the basics of birds, understand the role birds play in food chains and go bird watching using field guides and telescopes. Students will do hands-on activities. Students will use tools to build bird feeders, allowing them to attract birds at home.(3-4 hours) Exploring Your Watershed (6-8 grade) We all depend on clean water. Examining how our actions shape the waterways around us. Go on a hike to see first-hand some of the challenging water quality problems in a city. Students will test the water quality to determine the health of an ecosystem. * Each program is taught for a class with at least 10 students. * All programs include plenty of time outdoors. So please prepare proper clothing, sunscreen and insect killers for children. * To take part in a program , please email dcprograms@mdc.mo.gov. Question: Kids who are interested in plants will choose _ . Options: A: Winged Wonders B: Exploring your Watershed C: Becoming Bears D: Whose Clues?

Scientists now believe the phrase "as the crow flies" no longer means the shortest most direct route between two points. They say it is likely that crows and other day birds also choose AA-suggested routes, even though it makes their journeys longer. Scientists at Oxford University spent 10 years studying homing pigeons using global positioning satellite (GPS) and got a surprising result. The birds often don't use the sun to decide their directions. Instead they fly along motorways, turn at crossing and even go around roundabouts , adding miles to their journeys. "It really has knocked our research team sideways to find that after a decade-long international study, pigeons appear to ignore their inbuilt directional instincts and follow the road system," said Prof Tim Guilford, reader in animal behavior at Oxford University's Department of Zoology. Guilford said pigeons use their own navigational system when doing long distance trips or when a bird does a journey for the first time. "But once homing pigeons have flown a journey more than once, they can fly home on a habitual route, much as we do when we are driving or walking home from work," said Guilford. "In short, it looks like it is mentally easier for a bird to fly down a road. They are just making their journey as simple as possible." Question: Why do homing pigeons tend to follow the road system daring the r journey? Options: A: Because they don't have their inbuilt directional instincts now. B: Because their own navigational system doesn't work. C: Because it is too hard to use their own navigational system. D: Because it is easier to make journey simple by following road system.

Q: Read the article and select the best answer. Article: A volcanic eruption in Iceland has sent ash across northern Europe. Airlines have stopped or changed the flights across the Atlantic Ocean, leaving hundreds of passengers stuck in airports. Grimsvotn is one of the largest and most active volcanoes in Europe. What makes Grimsvotn different is that it lies under a huge glacier of ice up to 12 metres thick. The hot volcano heats up the ice above it, which then forms a layer of water between glacier and the volcano, keeping it stable. As the water flows out from under the glacier, the pressure lifts. The lava from the volcano then comes up to the surface. This is exactly what is happening today. Now airlines have to make changes to their flights so as not to fly through the clouds of volcanic ash. According to KLM, one of Europe's biggest airlines, airplanes cannot go under the cloud or over it. Going through the cloud can result in ash getting stuck in the airplane's engines, causing damage to the plane. The eruption has also caused problems for animals in Iceland. The volcano left ash and sharp, glass-like rocks all over the countryside. Farmers are keeping their animals inside to stop them eating ash-covered grass or the sharp objects. Question: how many passengers were forced to stay in the airport? Options: A: thousands of passengers B: hundreds of passengers C: ten thousands of passengers D: 20000 of passengers
A: B

Read the article and select the best answer. Article: Last Sunday, Aron Ralston, an experienced hiker and mountaineer, set off to walk alone through the Bluejohn desert canyon in Utah. He was planning an eight-hour, 21-kilometer hike. While he was climbing through a narrow part of the canyon, a big stone weighing about 400 kilos fell and trapped his right arm. When he failed to return to the mountain camp where he was staying that night, people simply thought he had decided to camp out somewhere in the canyon. When he still had not returned by Tuesday, the alarm was raised, A search party set out on Wednesday evening, but there we no sign and his family began to fear the worst. In fact, Ralston, 27, was lying trapped in the canyon. By Tuesday, he had run out of water. By Thursday, he realized that he would not survive unless he took unusual action, so he used his pocket knife to cut his arm below the elbow . He then climbed down to the bottom of the canyon. There he met two other hikers, who helped him back to safety. He received some help at a local hospital before being carried to St. Mary's hospital in Grand Junction, Colorado for surgery. Ralston's astonishing survival brought equal amounts of praise and criticism. While praising the climber for his bravery and calm, experts also pointed out he had broken the first rule of outdoor pursuits. He had failed to leave words with anyone of where he was going that day. This was in fact Ralston's second near-death experience. In February, he was buried up to the neck in snow by an avalanche while skiing in the Colorado Rockies. Ralston not only managed to dig himself out but he also rescued his skiing companion, who had been completely buried in the snow. Ralton rescued himself and his friend in less than 15 minutes.
