Article: Do you still remember the funny question: why did the chicken cross the road? To get to the other side. Most people know this joke. But recently, some people have been much more concerned with how the grizzly bear and mountain lion can cross the road. Millions of animals die each year on US roads, the Federal Highway Administration reports. In fact, only about 80 ocelots , an endangered wild cat exist in the US today. The main reason? Road kill. "Ecopassages" may help animals cross the road without being hit by cars. They are paths both over and under roads. "These ecopassages can be extremely useful, so that wildlife can avoid human conflicts," said Jodi Hilty of the Wildlife Conservation Society. But do animals actually use the ecopassages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an ecopassage that went under a highway. This showed that the lion used the passage. Builders of some ecopassages try to make them look like a natural part of an area by planting trees on and around them. Animals seem _ . Animals as different as salamanders and grizzly bears are using the bridges and underpasses. The next time you visit a park or drive through an area with a lot of wildlife, look around. You might see an animal overpass! Question: When the writer says that animals seem "to be catching on", he means _ . Yes or no, is the answer "animals begin to learn to use ecopassages"?
No

Article: The early 1900s were very different from today, when toys were still the delight of children everywhere. Theodore Roosevelt's Presidency marks the beginning of the "Teddy Bear". In the year 1902,toy bears were named "Teddy" after the president's nickname. The Teddy Bear became known worldwide and it was only a few years later that the Teddy Bears were mass produced. In 1913,an item called the Erector Set was invented. It was a steel,motorized toy that children could use to build models of anything. Its creator was A.C.Gilbert,a medical doctor. Charles Pajeau created a similar wooden set called Tinker Toys in the year 1914.Tinker Toys were made for younger children. Raggedy Ann dolls first came on the scene after newspaper cartoonist Johnny Gruelle reproduced the doll he made for his daughter. That was in 1915. The following year,an architect's son named John Lloyd Wright,invented Lincoln Logs,which were interlocked to make structures. Two years after Mickey Mouse was created,stuffed Mickey Mouse dolls were made by Charlotte Clark. This was the start of Disney merchandise. The yoyo became popular in the United States after Donald Duncan bought a yoyo company in 1929. The ViewMaster,a three dimensional viewer,was developed by a camera enthusiast named William Gruber. The toy became popular when Gruber licensed Disney characters to make still, 3D images from Disney movies and television programs. Finally,in 1940,model airplanes were mass produced. They started out as a way for manufacturers to sell planes to the military,but later caught on as a toy. The toys that we know and love today have had their roots from these ancient times. Thanks to all these creative man's efforts, we know otherwise what we may never know. Question: Why were toy bears named "Teddy"? Yes or no, is the answer "To memorize President Theodore Roosevelt"?

Article: Satellites play big roles in modern life. Some look downward to monitor environmental conditions on Earth.Others look outward in search of major solar flares that can trouble the transmission of electrical power to homes and businesses. Some spy on our enemies. Others relay communications around the globe. But all of these million-dollar wonders of technology can be knocked out by a collision with space junk ---debris ( )from satellites and other earthly technology orbiting high above the planet. Now,a teen from Jordan has designed a satellite to chase down space junk , collect it and then deal with it. Even bits of space junk as small as dots of paint pose a threat , says Dana. That's because this debris orbits our planet at speeds up to some 28,200 kilometers per hour. Such high speed explains why tiny paint dots have damaged the windshields of space shuttles so badly that they needed to be replaced. Researchers have come up with many ideas for getting rid of space junk. Some have suggested vaporizing small bits with lasers. Others have proposed launching satellites to collect the debris. Dana's design falls into this category. Here's how hers would work : A radar system aboard the satellite would scan and find a piece of space junk.Then,thrusters would change the satellite's orbit so that it could chase down _ . As the satellite closed in on its prey, cameras would keep it on target. At the last minute,a door that leads to a container would open. This container needs to be strong so that it doesn't break apart when the satellite swallows the space junk,Dana explains. Finally,when the trash container was full,it would be lowered toward the earth on a kilometer-long cable and its contents released into the upper atmosphere. There, the space junk would harmlessly burn up just like a meteor does. Meanwhile, her satellite would roll the container back up so that it could collect more trash. Question: According to the Dana's design, space junk in her satellite _ . Yes or no, is the answer "will be destroyed by heat in the upper atmosphere"?
