In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.
One example: Article: Homework can put you in a bad mood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.
Question: Researchers did experiments on kids in order to find out _ .

Now, solve this: 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.
Solution:
C
