[EX Q]: Article: People like to look in the mirror often when they have a young and beautiful face. However, when one grows old, nobody wants to see their wrinkled old face in the mirror any more. So, many old people seldom look at their faces in the mirror. This is completely wrong. According to Wu Zhenyun, a professor from the Psychological Research Institute under the Chinese Academy of Sciences, a person's willingness to look in the mirror can reflect his or her mentality. When people don't care too much about their age, they will try to carry themselves with ease and natural poise . They don't mind looking in the mirror to see their own faces. Some people even love to look in the mirror from time to time to see whether they keep a good appearance. In this way, mirror becomes their best friend that help them to look confident. On the other hand, some people are afraid of being old. They don't want to see the wrinkles on their face and their hair turning grey. So they don't want to look in the mirror. This actually reflects a negative attitude they hold towards life. In the long term, they might suffer from psychological pressure or some sort of depression, which is actually not a wise act. " Everyone can make themselves look charming at every age stage. If one is confident, one will always look beautiful, it shows that they accept themselves." professor Wu said. Mirror cannot only give confidence to one. By looking in the mirror, one can even find the traces of some diseases from one's own face.

[EX Q]: 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.
