Ques:Article: Three "Great Walls" built around the United States' Tornado Alley could reduce tornadoes from destroying billions of dollars in property and endangering millions of lives, a physicist has claimed. Professor Rongjia Tao of Temple University, Philadelphia unveiled a proposal this week calling for the construction of three 1,000-foot barriers up to 100 miles long, which would act like hill ranges and soften winds before tornadoes could form, the BBC reports. The $16.9 billion plan would call for the faux hill ranges in North Dakota, along the border between Kansas and Oklahoma, and in Texas and Louisiana, ostensibly saving billions of dollars in damage every year, Tao said. The walls would not shelter towns, he said, but instead would soften the streams of hot southern and cold northern air that form tornadoes when they clash in the first place. But critics laughed at Tao's proposals. Leading tornado experts pointed to areas that are already protected by hill ranges the size of the barriers Tao is proposing, yet still have plenty of tornados, like parts of Oklahoma, Arkansas and Missouri. And even if the plan did work, it would create more problems than it would solve, scientists said, by creating catastrophic weather side effects. "Everybody I know is of 100% agreement - this is a poorly conceived idea," Professor Joshua Wurman of the Center for Severe Weather Research. "From what I can gather his concept of how tornadoes form is fundamentally flawed . Meteorologists cringe when they hear about 'clashing hot and cold air'. It's a lot more complicated than that." Question: What's the main idea of the passage? Yes or no, is the answer "The different opinions on the proposal that the walls will reduce the loss caused by tornadoes."?

Ans:No

Ques:Article: At most schools, "going green" means generating less trash or making an attempt to recycle.But at New York's Riverdale Country School, it means being encouraged to run and even jump in the hallway. That's because the school was the first to install ( ) the specially-designed Pavegen floor tiles in America. The tiles use kinetic energy expanded by the kids and transform it into electricity that can be used to power classroom lights, science projects and charge electronic devices. The first US installation of Pavegen tiles near the school's student center is thanks to 14-year-old Zach Halem, who managed to convince the officials to purchase them. Besides providing fun green energy, the tiles also serve as a learning tool. Every time a student steps on one, a brightly-lit LED board provides instant feedback on how much energy was generated. Depending on the force, every step results in between one to seven watts-enough power to light an LED street lamp for about 30 seconds. Made largely from rubber and other recycled materials the tiles are invented by the 26-year-old British industrial designer Laurence Kembell-Cook. While new to the US, they have been installed in numerous places in Europe, ranging from a London underground station to a marathon track in Paris. However, it was not until Pavegen started getting popular in London schools that Laurence realized that his invention not only saved energy, but was also fun! Though the young inventor will not give too many details about the technology behind this green tile, he says that it is very different from other kinetic energy harvesting systems. Whatever the secret, let's hope more US schools decide to install these fun tiles. In fact, why stop at schools? These tiles could be installed everywhere, from sidewalks to homes. Then we could all be "green" and have fun! Who knew that was even possible? Question: Which part of a website is the passage probably taken from? Yes or no, is the answer "Science."?

Ans:No

Ques:Article: Once in a blue moon, there is one on New Year's Eve. Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't expect it to be blue - the name has nothing to do with the color of our closest celestial neighbor. A full moon occurred on December 2. It will appear again on Thursday in time for the New Year's countdown. The New Year's Eve blue moon will be visible in the United States, Canada, Europe, South America and Africa. For partygoers in Australia and Asia, the full moon does not show up until New Year's Day, making January a blue moon month for them. A full moon occurs every 29.5 days, and most years have 12. On average, an extra full moon in a month - a blue moon - occurs every 2.5 years. The last time there was a lunar double take was in May 2007. New Year's Eve blue moons are rarer, occurring every 19 years. The last time was in 1990; the next one won't come again until 2028. "Blue moons have no astronomical significance," said Greg Laughlin, an astronomer at the University of California. "'Blue moon' is just a name in the same sense as a 'hunter's moon'(a full moon in octorber) or a 'harvest moon,'" Laughlin said in an e-mail. The popular definition of blue moon came about after a writer for Sky & Telescope magazine in 1946 misinterpreted the Maine Farmer's Almanac and labeled a blue moon as the second full moon in a month. In fact, the almanac defined a blue moon as the third full moon in a season with four full moons. Question: Compared with the hunters moon, the blue moon _ . Yes or no, is the answer "is rarer"?

Ans:No
