Ques:Article: BUKHANNON, West Virginia--Two rescue teams slowly moved along a two-mile path on Monday night to the site of a coal mine explosion that trapped 13 miners, who had not been heard from since the early morning accident. Meanwhile, at a nearby church, more than 250 family members and friends gathered, waiting for updates on the rescuers' progress. The miners were trapped at about 6:30 and many families weren't informed of the accident until about 10 a.m-more than three hours after it happened."It's very upsetting, but you've got to be patient, I guess," said John Helms, whose brother, Terry, was trapped in the mine. The trapped miners were about 260 feet underground and about 10,000 feet from the Sago Mine's entrance, said Roger Nicholson, general counsel from International Coal Group. At a late night news conference, Nicholson said one team had advanced about 4, 800 feet in the four hours since entering the mine just before 6 p.m.Another team entered the mine about 30 minutes later. He said the crew was very experienced, with some members having worked underground for 30 to 35 years.The miners were equipped with about one hour of breathable oxygen each.The company has not released the names of the miners. The teams test the air about every 500 feet, and have to disconnect (remove) the power to the phones they use to communicate with the surface before doing that." We don't want to be energizing anything if it's in an atmosphere with burnable gases," Kips said. The cause of the explosion was not immediately known.High levels of carbon monoxide were discovered shortly after the explosion, which delayed rescue efforts, but those levels have since subsided , authorities said. Question: If the first team advanced at an average speed, they could dig about _ per hour. Yes or no, is the answer "1,200feet"?

Ans:Yes

Ques:Article: Australia is largely a nation of immigration , with one in four of Australia's 21 million population born overseas. But immigrations hoping to become Australian citizens will soon have to take a test examining their knowledge of the country's history and institutions. While Australia prides itself on its multicultural background, the government wants newcomers to integrate more fully . Form later this year, new immigrants will have to show an understanding of the English language. They will also be required to answer 20 questions from a list of 200. Anyone who gives fewer than 12 correct responses will not be accepted. Immigrants will also have to accept what the government considers to be 10 important Australia values, including "mateship" and "giving people a fair go". Other important Australia values are said to include tolerance, compassion, gender equality and freedom of speech. The new citizenship application procedures are detailed in a 40-pages booklet . It describes Australia as "a nation at ease with the world and itself" but says that newcomers are expected to respect its values. The booklet sums up mateship as voluntary helping and receiving help from others, especially in difficult times. The immigration Minister said they aimed to achieve a balance between ethnic diversity and social stability , "particularly as we now draw people from so many different countries and so many different cultures". Critics have attacked the English language requirement, pointing out many immigrants could not speak English when they arrived. But the minister said, "We are trying to encourage people to learn English, because we think that is the way they will achieve their dreams in Australia." Question: Which is one of the reasons for the change of application? Yes or no, is the answer "To promote Australia ' values"?

Ans:No

Ques:Article: WASHINGTON--Two-thirds of the world's polar bear population could be gone by 2050 if predictions of melting sea ice hold true, the US Geological Survey reported on Friday. The fate of polar bears could be even worse than that estimate, because sea ice in the Arctic might be disappearing faster than the available computer models predict, the geological survey said in a report aimed at determining whether the big white bear should be listed as a threatened species. "There is a definite link between changes in the sea ice and the welfare of polar bears," said Steve Amstrup, who led the research team. He says Arctic sea ice is already at the lowest this year and is expected to retreat farther this month. That means that polar bears--some 16,000 of them -- will disappear by 2050 from parts of the Arctic where sea ice is melting most rapidly, along the north coasts of Alaska and Russia, researchers said in a telephone briefing . Other polar bears could survive beyond that date but many of those could be gone by 2100, Amstrup said. By this century's end, the only polar bears left might live in the Canadian Arctic islands and along the west coast of Greenland. "It is likely to result in loss of approximately two-thirds of the world's current polar bear population by the mid 21st century," the report's executive summary said. "Because the observed trajectory of Arctic sea ice decline appears to be underestimated by currently available models, this assessment of future polar bear status may be conservative ." In January, the US Fish and Wildlife Service proposed listing the polar bear as a threatened species, noting polar bears depend on sea ice as a platform to hunt seals, their main food. Without enough sea ice, polar bears would be forced onto land, but they are poor hunters once they get out of the water and ice, the researchers said. The bears' disappearance would probably take place as young cubs failed to survive to adulthood and females were unable to reproduce successfully. Question: What was the US Geological Survey intended to do? Yes or no, is the answer "To determine whether the polar bear was in danger."?

Ans:No

At one point she had all four paws on the camera and was keeping her balance. Mr Czapp added, "She jumped up there several times and I realized it could make a good picture. As I was leaving with the public's viewing window behind me, I thought I heard the camera go off but didn't think much of it. But when I checked the memory card afterwards, I was amazed to see Jessie had actually taken two pictures of me photographing her. I couldn't believe a fox had gained an advantage over me!
