Article: Homework can put you in a badmood , 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.

New input: Article: Kodak's decision to apply for bankruptcy protection is a sad, though not unexpected, turning point for a leading American corporation that pioneered consumer photography and dominated the film market for decades, but finally failed to adapt to the digital revolution. Although many attribute Kodak's downfall to "complacency ," that explanation doesn't admit the efforts with which the company went to reinvent itself. Decades ago, Kodak invented the first digital camera in 1975 -- but in a fateful decision, the company chose to focus on its traditional film business. Large companies have a difficult time switching into new markets. For example, although Kodak predicted the rise of digital photography, its culture was too rooted in the successes of the past to fully welcome the future. In the past, their history was so important to them. Now their history has become a liability. Kodak's downfall over the last several decades was dramatic. The 1980s brought new competition from Japanese film company Fuji Photo, which weaken Kodak by offering lower prices. Kodak's decision not to pursue the role of official film for the 1984 Los Angeles Olympics was a major loss. The bid went instead to Fuji, which exploited its sponsorship to win a key role in the market.

Options: (A) It went bankrupt all of a sudden. (B) It is approaching its downfall. (C) It is playing a dominant role in the film market. (D) It started the digital revolution in the film industry.
Asnwer: B
Solution:
Yes
