Article: The United States government is back in business. Early Thursday morning, President Barack Obama signed a bill to reopen the government. The budget bill, drafted by Senate late on Wednesday night, raised the government's debt ceiling and averted a serious economic crisis. "With the shutdown behind us," Obama said after the Senate vote, "we now have an opportunity to focus on a sensible budget that is responsible, that is fair and that helps hardworking people all across this country." Now that a settlement has been reached, formerly furloughed employees have returned to work, national museums and parks are reopening, and the government's gears are slowly beginning to turn again. Before the shutdown, a federal funding bill went back and forth between the Senate and the House. A major issue was whether or not the government would pay for changes in Obama's healthcare plan. The Senate, with a Democratic majority, wanted to pass a budget that would fund the new healthcare law. But the House, which has a Republican majority, did not want government money used that way. Because an agreement could not be reached on a budget plan, the government was forced to partially shut down. Sixteen days later, _ have come together to pass a measure that raised the country's debt ceiling. The debt ceiling is the strict legal limit Congress places on the amount of money that can be borrowed each year. Had this agreement not been met by October 17, the U.S. may not have been able to pay its promised payments. This legislation, or law, will fund the government through January 15. During this time, Obama and Congress will work on a long-term spending plan. The effects of the two-week government shutdown were widespread. In addition to national parks, museums, memorials and monuments were off-limits to visitors. Workers at government-run organizations like NASA and the Environmental Protection Agency were furloughed. Part of the new legislation will pay back the 800,000 workers who were without pay during the shutdown. Early Thursday, the Smithsonian Institution celebrated the government's reopening on Twitter. "We're back from the shutdown!" they wrote, announcing that museums would reopen Thursday and the National Zoo in Washington on Friday. To the delight of many people, that also means the return of the zoo's popular live Panda camera.
Question: What may have lead to the government shutdown?
Options: (A) Economic crisis. (B) The senate voting. (C) Dispute on the budget bill. (D) Lazy people across the country.

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.

Article: Cutting global warming pollution would not only make the planet healthier, it would make people healthier too, new research suggested. Cutting carbon dioxide emissions could save millions of lives, mostly by reducing preventable deaths from heart and lung diseases, according to studies released Wednesday and published in a special issue of The Lancet, a British medical journal. "Relying on fossil fuels leads to unhealthy lifestyles, increasing our chances of getting sick and in some cases takes years from our lives," US Health and Human Services Secretary Kathleen Sebelius said in a telecast briefing from her home state of Kansas. "As greenhouse gas emissions go down, so do deaths from cardiovascular and respiratory diseases. This is not a small effect." Instead of looking at the health ills caused by future global warming, as past studies have done, this research looks at the immediate benefits of doing something about the problem, said Linda Birnbaum, director of the US National Institute of Environmental Health Sciences. Some possible benefits seemed highly speculative, the researchers conceded, based on people driving less and walking and cycling more. Other proposals studied were more concrete and achievable, such as reducing cook stoves that burn dung , charcoal and other polluting fuels in the developing world. And cutting carbon dioxide emissions also makes the air cleaner, reducing lung damage for millions of people, doctors said. "Here are ways you can attack major health problems at the same time as dealing with climate change," said lead author Dr. Paul Wilkinson, an environmental epidemiologist at the London School of Hygiene and Tropical Medicine. Wilkinson said the individual studies came up with numbers of premature deaths prevented or extra years of life added for certain places. For example, switching to low-polluting cars in London and Delhi, India, would save 160 lost years of life in London and nearly 1,700 in Delhi for every million residents, one study found. But if people also drove less and walked or biked more, those extra saved years would soar to more than 7,300 years in London and 12,500 years in Delhi because of less heart disease.
Question: What does the passage mainly talk about? _ .
Options: (A) How can people live longer? (B) Cutting carbon dioxide emissions saves lives. (C) Global warming threatens people's lives. (D) People should stop relying on fossil fuels.
